$Delhi, India: India’s Aircraft Accident Investigation Bureau (AAIB) has released its preliminary findings into the crash of a Tecnam P-Mentor trainer aircraft operated by Redbird Flight Training Academy, which went down during a routine training sortie near Suktara Airfield in Madhya Pradesh on December 8, 2025, injuring both occupants. The accident involved aircraft VT-RFO, which was conducting a circuit and landing check when it suffered a sudden loss of engine power on final approach, forcing the instructor to attempt an emergency landing. The aircraft struck a power cable and crash-landed in a field approximately 920 metres from the runway threshold, the report said. The impact snapped a 33 kV power line, triggering an outage across 80–90 nearby villages. According to the AAIB, the aircraft had already completed two touch-and-go landings earlier in the sortie and was on its third approach when the incident occurred. As the aircraft turned onto final approach to Runway 10 at Suktara, the instructor, noting the runway perspective, asked the trainee pilot to increase power. The trainee responded that the engine power was already set at approximately 75 percent. Moments later, both pilots observed a drop in engine RPM, indicating a loss of power. The instructor immediately took control, informed air traffic control of a forced landing, and maneuvered the aircraft to the right of the approach path while maintaining landing configuration. During the descent, the aircraft struck an overhead power cable and crash-landed in an adjacent field. There was no post-impact fire, and the emergency locator transmitter activated automatically The flight instructor sustained minor injuries, while the trainee pilot suffered a serious injury, including a maxillary fracture, the report noted. The aircraft was substantially damaged, with broken propeller blades, bent engine mounts, collapsed landing gear, fuselage structural damage, and damage to the engine oil, coolant, and exhaust systems VT-RFO, manufactured in 2024, was powered by a Rotax 912 iSc3 Sport piston engine and had valid certificates of registration and airworthiness at the time of the accident. Maintenance records reviewed by investigators showed no deferred defects, and the aircraft had completed a 50-hour inspection less than three weeks prior to the crash. The trainee pilot had accumulated 46 hours and 40 minutes of total flight time, with just over three hours on type, while the instructor held more than 2,250 flight hours, including 420 hours on the Tecnam P-Mentor. Both pilots had adequate rest prior to the flight and tested negative in pre-flight breath analyser checks The flight was conducted under day VFR conditions. While Suktara Airfield does not have a formal meteorological facility, local weather observations indicated five kilometres visibility and light winds at the time. The aircraft took off shortly before sunset, which occurred at 1158 UTC, with the crash taking place at approximately 1226 UTC AAIB clarified that the report is preliminary and does not establish a final cause. Investigators have secured the wreckage, retrieved data from the aircraft’s Garmin display memory card, and collected fuel and oil samples for laboratory analysis. The Engine Control Unit (ECU) is also scheduled for detailed examination to assess engine health and performance parameters. The sole objective of the investigation is the prevention of accidents and incidents, the bureau stated, noting that findings remain subject to change pending further analysis.$

AAIB Preliminary Report Flags Engine Power Loss In December 2025 Redbird Aircraft Crash

$Louisville, United States: Federal investigators have identified a crucial aircraft component with a known history of failures as a key focus in the ongoing probe into the UPS Cargo Flight 2976 crash that killed 15 people in November 2025. The National Transportation Safety Board (NTSB) disclosed this week that the metal housing around a spherical bearing assembly part of the structure securing the left engine to the wing on the McDonnell Douglas MD-11F freighter exhibited signs of metal fatigue and cracking before breaking during takeoff. The failure of this part is believed to have precipitated the catastrophic sequence that ended in the fatal crash. Flight 2976 departed from Louisville Muhammad Ali International Airport on Nov. 4, 2025, bound for Honolulu, Hawaii. Seconds after beginning its takeoff roll on Runway 17R, the aircraft’s left engine and its pylon separated from the wing. Surveillance footage reviewed by investigators shows the engine detaching and vaulting up and over the fuselage as the freighter lifted briefly into the air before descending into an industrial area just beyond the airport perimeter. The crash claimed the lives of all three crewmembers aboard and 12 people on the ground, and left numerous others injured. The NTSB has confirmed the component at the center of the investigation, the metal housing around the spherical bearing connecting the engine pylon to the wing had a documented history of four prior failures on other MD-11 aircraft, according to a Boeing service advisory issued in 2011. At that time, Boeing, which later acquired McDonnell Douglas, determined the issue did not constitute a “safety-of-flight condition” and recommended visual inspections rather than a mandatory redesign. The advisory also suggested a newer version of the part that eliminated the design feature where cracks can initiate, but did not compel operators to adopt it. Investigators are now reviewing how that advisory was incorporated into routine maintenance and whether inspectors and operators, including UPS, followed the recommendations. Preliminary NTSB findings show that detailed inspections of the engine mount parts were last performed in October 2021, and the aircraft was not scheduled for another detailed check until several thousand more flight cycles were completed. Critics have questioned whether the existing inspection intervals were sufficient to detect the developing fatigue cracks. The MD-11 involved was 34 years old, an age at which structural components on aircraft are more susceptible to wear and fatigue. All MD-11 and related DC-10 models remain grounded across U.S. cargo fleets pending enhanced inspections and corrective actions. The NTSB has recovered both the flight data recorder (FDR) and the cockpit voice recorder (CVR). Analysis of the cockpit recordings and detailed metallurgical examinations of the fractured parts continue as investigators work toward a final probable cause determination. The board has not yet released a complete conclusion on the chain of failures that led to the engine separation. UPS has reiterated its cooperation with the ongoing investigation and expressed condolences to victims’ families. Boeing has acknowledged the probe but has not issued further comment beyond confirming the existence of the earlier service advisory.$

Muan County, South Korea: South Korea’s Ministry of Land, Infrastructure and Transport has formally admitted that a key navigation structure at Muan International Airport did not meet safety standards and likely contributed to the severity of Jeju Air Flight 2216 crash flying from Bangkok to Muan International Airport in South Korea, on December 29, 2024, during an emergency landing after suspected landing gear issues. The aircraft belly‑landed, skidded off the runway, and collided with a concrete embankment, which caused a catastrophic explosion and contributed to the high fatality count. Of the 181 people on board 175 passengers and 6 crew 179 were killed, with only two flight attendants surviving with serious injuries. Earlier South Korea’s parliament had approved an independent investigation into the December 2024 Jeju Air crash that killed 179 people, responding to delays and criticism of the official probe. Under the new law passed on December 22, 2025, an 18‑member cross‑party panel will examine all aspects of the disaster including potential mechanical issues, bird‑strike risk, the aircraft’s final moments, and whether government agencies tried to conceal findings by the main investigation body. This independent review follows growing pressure from victims’ families and lawmakers for greater transparency and credibility in the ongoing examination of the country’s deadliest aviation accident. The aircraft, Jeju Air Flight 2216, a Boeing 737-800 arriving from Bangkok, belly-landed on the runway after suffering a suspected bird strike that disabled its landing gear. It then overran the runway and struck a concrete mound supporting the localizer system, a navigation aid used for precision approaches triggering a catastrophic explosion. Only two cabin crew members survived. Opposition lawmaker Kim Eun-hye released documents from a government-commissioned analysis indicating that the concrete mound should have been designed to be fragile, able to break easily upon impact given its proximity (less than 240 m) to the runway end. Under airport safety operation standards, such structures must be breakable if situated within this safety area to minimize impact forces in runway overruns. The ministry acknowledged that during a 2020 upgrade project, the mound was not modified to meet these criteria. Simulations by the Korean Society of Computational Structural Engineering, commissioned by the Aviation and Railway Accident Investigation Board, found that without the rigid concrete mound the aircraft could have slid to a stop after sliding beyond the runway without sustaining fatal structural damage. A frangible design would similarly have greatly reduced impact severity, possibly allowing the aircraft to breach the perimeter fence and slide into open terrain with no serious injuries expected. The ministry’s admission has reignited criticism from politicians and victim families, with some lawmakers arguing the disaster was largely preventable and that longstanding regulatory oversights were to blame. Opposition figures described the embankment as a “mound of death” and alleged that officials attempted to suppress or delay release of critical safety findings. In parliament, a special committee is examining the crash and broader aviation safety protocols. Rep. Kim Eun-hye has accused the government of negligence dating back decades, asserting that the structure violated both domestic and international safety practices. Families of the victims are demanding greater transparency and accountability. While the simulation report has heightened focus on the airport structure, a final official investigation by the Aviation and Railway Accident Investigation Board is still pending. Prosecutors and police have separately searched offices of Jeju Air and airport operators for documents related to aircraft operations and runway safety features. Experts continue to examine multiple factors in the crash, including whether the aircraft’s engines were functioning at impact and whether procedural or emergency response issues contributed to the outcome. In the aftermath of the crash, the Transport Ministry and airport authorities have pledged to review and upgrade runway safety areas nationwide, ensuring that navigational aids and nearby structures comply with both domestic regulations and International Civil Aviation Organization (ICAO) standards. Reports indicate plans to remove the concrete embankment at Muan and replace it with breakaway installations at Muan and other regional airports.

New Delhi, India: India’s Aircraft Accident Investigation Bureau (AAIB) has recommended a comprehensive one-time inspection of airlines’ safety management systems (SMS) by the Directorate General of Civil Aviation (DGCA), following its 35-page final investigation report into a serious air proximity incident involving two IndiGo aircraft in Delhi airspace on November 17, 2023. The incident involved IndiGo Flight IGO2113, an Airbus A321 operating from Delhi to Hyderabad, and IndiGo Flight IGO2206, an Airbus A320 operating from Delhi to Raipur. The two aircraft came dangerously close to each other shortly after departure, breaching the minimum separation standards mandated for controlled airspace. Fortunately, the Traffic Collision Avoidance System (TCAS) alerts helped pilots maintain safe separation, and no injuries or damage to the aircraft were reported. The AAIB’s final report identified multiple factors that contributed to the near-miss. The crew of IGO2113 failed to correctly set up and verify the Standard Instrument Departure (SID) data, which is critical for maintaining a safe climb trajectory. In addition, monitoring during the climb phase was insufficient, leading to reduced vertical and lateral separation from IGO2206. The bureau also noted that six previous SID deviation events involving IndiGo aircraft between August and November 2023 had not been reported through mandatory safety reporting channels, highlighting weaknesses in both the airline’s internal safety culture and compliance with regulatory requirements. In response to these findings, the AAIB has recommended that the DGCA carry out a one-time inspection of the safety management systems of all scheduled operators and the Air Navigation Service Provider. The goal is to evaluate the effectiveness of hazard identification, risk assessment, and reporting culture, as well as compliance with mandatory occurrence reporting. The AAIB has also emphasized that airlines must ensure that all previous and future incidents are reported promptly and accurately to both the DGCA and the AAIB. The Airports Authority of India (AAI) has been advised to review ATC procedures, particularly during high-intensity simultaneous departures, and to assess the Short Term Conflict Alert (STCA) system and airspace design to prevent future separation breaches. IndiGo has been recommended to take corrective action by ensuring accurate entries into the Flight Management and Guidance System (FMGS), minimizing cockpit disturbances during pre-flight setup, and strengthening cross-checks during training. Aviation safety experts note that these recommendations are critical for maintaining operational safety, especially as India’s air traffic continues to grow rapidly. The AAIB’s recommendations focus on the importance of robust safety management system audits, procedural discipline, and a culture of compliance to prevent near-misses from escalating into accidents. The DGCA is expected to follow up on the AAIB’s recommendations, potentially conducting targeted inspections across airlines and air navigation services to identify and rectify systemic vulnerabilities. The incident and the bureau’s final report highlight the vital role of near-miss investigations in reinforcing aviation safety, ensuring that lessons from minor incidents are institutionalized and preventive measures are implemented effectively.

Seoul, South Korea: South Korea’s National Assembly has passed legislation to establish an independent parliamentary investigation into the December 2024 Jeju Air plane crash, intensifying scrutiny of the official accident inquiry and responding to mounting pressure from victims’ families and lawmakers. The bill, approved on 22 December 2025, empowers an 18-member panel of lawmakers to conduct a comprehensive review of the crash that killed 179 people, making it the deadliest aviation disaster in South Korean history. Lawmakers involved in the inquiry will have powers to subpoena officials, demand documents and hold hearings with representatives from the transport ministry, aviation authorities, Jeju Air and other relevant bodies. Relatives of the victims have voiced growing frustration over the pace and transparency of the official probe. According to parallel reporting, families question the credibility of the existing investigation and allege it has failed to resolve key questions nearly a year after the crash. At memorial events marking the anniversary of the tragedy, families lit candles and demanded full accountability, emphasizing that the delay in public findings deepened their pain and hindered trust in official processes. President Lee Jae Myung issued a public apology to the families, recognizing their anguish and pledging to uncover the truth behind the disaster. He acknowledged systemic issues in how aviation safety is overseen and stressed the need for meaningful reforms. Authorities and investigators have grappled with technical challenges related to the crash probe. Interim reports indicated that both engines sustained bird strikes, and subsequent analysis found that one engine was shut down despite sustaining less damage than the other, raising questions about crew actions and procedural adherence. Additionally, past updates have shown broader industry implications, including regulatory discussions on runway safety infrastructure and aircraft oversight. The Jeju Air incident has reverberated across South Korea’s aviation sector and political landscape, fuelling debate over accident investigation independence, aviation infrastructure standards, and public accountability. The parliamentary inquiry, set to conduct its work over a designated period with possible extensions, represents a significant escalation in legislative involvement in aviation oversight.

Washington, United States: The United States government has formally acknowledged partial fault in the January 29 mid-air collision between the U.S. Army Black Hawk helicopter and a commercial regional jet near Ronald Reagan Washington National Airport, a disaster that claimed 67 lives and stands as the deadliest aviation accident on U.S. soil in more than two decades. In a 209-page federal court filing responding to a wrongful-death lawsuit filed by the family of victim Casey Crafton, the Department of Justice stated that the government “owed a duty of care to Plaintiffs, which it breached, thereby approximately causing the tragic accident.” The admission of liability is rare in aviation cases and directly acknowledges failings by both military and civilian aviation entities. According to the court filing, the Army helicopter crew did not maintain “appropriate and safe visual separation” from the approaching regional jet, a Bombardier CRJ-700 operating as American Eagle Flight 5342 from Wichita, Kansas, carrying 60 passengers and four crew. The helicopter was conducting a night-vision goggle training mission. The Justice Department also acknowledged that an air traffic controller at Reagan National Airport failed to follow Federal Aviation Administration (FAA) procedures for visual separation of aircraft, a critical lapse in a congested airspace where civilian and military traffic intersect. Although the government admitted it bore responsibility, it said that other parties, including American Airlines and its subsidiary PSA Airlines, also played roles and have filed motions to dismiss claims against them. The collision occurred at approximately 8:46 p.m. EST over the Potomac River, just before the regional jet was to land on Runway 33. All 64 occupants of the passenger aircraft perished along with the three soldiers aboard the helicopter. Prior investigations identified the helicopter’s altitude exceeding its designated flight path limits and questioned whether night-vision equipment and a malfunctioning altimeter may have hindered the crew’s ability to detect the oncoming jet. Among those killed were members of the figure skating community, coaches, and family members returning from a competition, a factor that drew public attention and intensified scrutiny of safety practices. Legal experts described the government’s admission as unusual and a significant development for the families seeking compensation. The move allows lawsuits to proceed under the Federal Tort Claims Act, a statute that waives sovereign immunity under defined circumstances. A widow of a passenger killed in the collision had filed a wrongful-death lawsuit against American Airlines, the Federal Aviation Administration (FAA) and the U.S. Army, alleging the carriers and government agencies failed in their duty to protect the flying public; the suit, filed on behalf of her late husband, claims oversight lapses and ignored warning signs contributed to the crash and seeks accountability and compensation for victims’ families. Separately, lawmakers have responded with legislative action. The U.S. The Senate recently passed bipartisan safety legislation requiring advanced tracking systems, such as Automatic Dependent Surveillance–Broadcast (ADS-B), on military helicopters operating near civilian airports, a measure aimed at preventing similar tragedies. NTSB preliminary findings indicate that faulty altitude data and gaps in air traffic control oversight were significant factors in the January 29 Potomac River mid-air collision, suggesting that the U.S. Army Black Hawk helicopters may have been flying higher than its intended altitude because onboard barometric altimeters were under-reading actual height, while air traffic controllers relied on inadequate situational information and procedures that failed to detect or resolve these discrepancies before impact. The board’s early analysis also highlighted systemic weaknesses in how visual separation responsibilities and helicopter route structures were managed in the congested Reagan National Airport airspace, underscoring both technical and procedural lapses that contributed to the fatal convergence of the helicopter and the American Airlines regional jet. The National Transportation Safety Board (NTSB) continues its independent probe. A final probable-cause report, expected in early 2026, will provide a definitive technical explanation of the collision and recommendations to improve airspace safety.

Beijing, China: A Beijing court has delivered a significant legal ruling in one of the longest-running civil matters connected to the disappearance of Malaysia Airlines Flight MH370, ordering the airline to pay compensation to the families of eight passengers more than 11 years after the aircraft vanished. On 8 March 2014, Flight MH370, a Boeing 777 operating from Kuala Lumpur to Beijing, disappeared from radar just under an hour after take-off with 239 people on board. Despite extensive international search efforts in the southern Indian Ocean and intermittent private expeditions, the main wreckage of the aircraft has never been found and the cause of its disappearance remains unresolved. The Chaoyang District People’s Court in Beijing ruled that Malaysia Airlines must pay 2.9 million yuan (approximately US$410,000) to each of the eight families whose relatives were aboard the flight and have now been legally declared dead. The compensation is intended to cover funeral expenses, emotional distress, and other financial losses, according to the court statement. This judgment represents the first formal Chinese court decision awarding damages in MH370-related litigation. A spokesman for the court said that 47 other cases were withdrawn after the families reached out-of-court settlements with Malaysia Airlines and its international arm, while 23 cases remain pending in the Chinese legal system. Most of the passengers on MH370 were Chinese nationals, giving Chinese courts jurisdiction over compensation claims under international air law and domestic regulations. Under the Montreal Convention, airlines are liable for proven damages in international air transport, with additional court proceedings often required to quantify emotional and non-economic damage. Malaysia Airlines has not publicly commented on the ruling at the time of publication. The compensation ruling comes as renewed interest and activity surrounds the ongoing search for MH370’s wreckage. Malaysian authorities have announced plans to restart a seabed search operation at the end of December 2025, focusing on a designated area of the Indian Ocean informed by the latest data and analysis from marine robotics firm Ocean Infinity operating under a “no-find, no-fee” contract. This new search phase underscores the enduring quest for answers from families and aviation experts nearly a decade and a half after the disappearance of the flight, one of the most enduring mysteries in modern aviation history.

Auckland, New Zealand: An Airbus A320‑Neo operated by Air New Zealand (Flight NZ249) experienced an uncommanded engine shutdown mid‑flight last year, due to a defective fire‑switch, the Transport Accident Investigation Commission (TAIC) confirmed in its interim report released on 4 December 2025. The incident occurred on 1 December 2024, when the aircraft was en route from Wellington to Sydney. Approximately 40 minutes after takeoff, the No. 2 engine unexpectedly shut down following activation of the overhead fire‑switch despite no pilot input. The crew declared a mayday and safely diverted to Auckland Airport, with all 154 passengers and crew unharmed. TAIC’s report identifies internal damage to the fire‑switch mechanism as the primary cause. A retaining pin inside the switch had bent, reducing the latching security and allowing vibration or normal operation to trigger the switch inadvertently. Inspections revealed that the panel surrounding the switch also showed signs of deformation, further contributing to the uncommanded activation. “The fire‑switch is designed to be manually operated only in case of an actual engine fire,” TAIC noted. “Its activation without pilot input posed a significant safety risk.” The commission also highlighted that the same fire‑panel design is used across the global A320 fleet indicating that other aircraft could potentially be affected. The switch manufacturer had issued service bulletins in late 2024 recommending inspection of previously repaired panels, but those checks focused on visually detectable external damage. Following the ANZ incident, Airbus expanded its guidance to inspect all affected fire‑panels for any signs of deformation within 1,000 flight cycles. The European Union Aviation Safety Agency (EASA) has since issued an Airworthiness Directive mandating such inspections and, where necessary, replacement of defective panels. Air New Zealand reportedly removed suspect panels from its fleet in early December 2024. On 28 November 2025, Airbus triggered another major safety action ordering a global recall of approximately 6,000 A320‑family aircraft, following a serious mid‑air flight‑control issue linked to corruption of flight‑control data under intense solar radiation. In a statement, Airbus described the recall as “precautionary,” urging all operators worldwide to apply an immediate software rollback (or, where required, hardware modifications) before affected aircraft are flown again. This recall reportedly the largest in Airbus’s 55‑year history affects over half of the global A320 fleet and has already prompted airlines across the U.S., Europe, Asia and beyond to ground jets for urgent software updates.

New Delhi, India: The Directorate General of Civil Aviation (DGCA) has grounded an Air India Airbus A320 aircraft and launched a formal investigation after it was found to have operated eight commercial flights without a valid Airworthiness Review Certificate (ARC). The lapse was discovered during a routine night‑halt inspection by an engineer, who noticed the aircraft’s ARC had expired. The certificate is mandatory to ensure the aircraft meets maintenance and safety standards before any flight. DGCA officials confirmed the aircraft had flown eight “revenue sectors” on 24–25 November 2025, despite the absence of a valid ARC. Flying without this certificate is considered a serious compliance violation as it directly pertains to flight safety. Following the discovery, DGCA immediately grounded the aircraft and suspended all personnel responsible for approving its release to service pending the outcome of the investigation. The regulator has also instructed Air India to conduct an internal compliance audit to identify systemic gaps and prevent future lapses. In a statement, Air India acknowledged the incident, calling it “regrettable.” The airline said it self-reported the breach to DGCA, suspended the staff involved, and initiated its own internal investigation. It reaffirmed its commitment to strict safety and regulatory compliance. Operating an aircraft without a valid airworthiness certificate poses significant safety risks and could potentially impact insurance coverage for the aircraft, including hull, liability, and passenger insurance. It has been described as a Level‑1 violation, the most serious type of compliance failure concerning aircraft safety standards. The aircraft was part of the former Vistara fleet, which merged with Air India in late 2024. After the merger, DGCA renewed ARCs for 69 of 70 aircraft. The 70th aircraft, which later operated eight sectors, had undergone an engine change, during which its ARC expired. Despite this, it was mistakenly released into service. DGCA’s inquiry will determine whether penalties, fines, or further actions against responsible personnel are warranted. Air India’s internal investigation will also examine systemic compliance gaps and recommend measures to prevent recurrence.

Louisville, United States: The National Transportation Safety Board (NTSB) said on Thursday its preliminary investigation into the Nov. 4 crash of UPS Flight 2976 in Louisville has identified fatigue cracks and areas of overstress failure on the left engine pylon aft mount lug, a structural connection that attaches the engine/pylon assembly to the wing. Investigators said the cracking preceded the accident and likely contributed to the pylon’s structural failure and subsequent separation of the left engine during takeoff. The accident involved MD-11F freighter N259UP, operating a domestic UPS cargo flight from Louisville Muhammad Ali International Airport (SDF) to Honolulu, which was destroyed after impacting terrain shortly after liftoff. All three crewmembers aboard the aircraft and eleven people on the ground were fatally injured; 23 additional people on the ground were reported injured. The NTSB opened its investigation the day after the accident and recovered perishable data and wreckage for examination. According to the preliminary report, investigators documented evidence of fatigue cracking in the left pylon aft mount lug and signs of overstress on adjacent structure. The report notes that when one side of the pylon support failed from fatigue cracking, the remaining structure could not carry the redistributed load and experienced overstress failure. Investigators are now focused on the component’s maintenance and inspection history to determine why the cracks were not detected. NTSB officials said the discovery of fatigue cracks is a “major clue” in determining how the structural failure began but emphasized the investigation remains ongoing. The NTSB has invited parties including the FAA, UPS, Boeing (which acquired the MD-11 program after merging with McDonnell Douglas), GE Aerospace, and labor representatives to participate in the probe, and it will continue to collect and analyze flight data, maintenance records and metallurgical evidence. A final report is typically issued about a year after an accident. The preliminary finding prompted immediate regulatory and industry responses. Boeing recommended that operators temporarily ground MD-11 aircraft pending further analysis; several carriers, including UPS and FedEx, temporarily removed MD-11s from service. The Federal Aviation Administration issued airworthiness directives that temporarily grounded the MD-11 and the related DC-10 model because of design commonalities affecting the pylon/wing attachment. Local officials and first responders described a scene of intense destruction on impact. Video and photographic evidence included in the NTSB packet show the left engine separating from the aircraft and the airplane striking structures near the airport perimeter before being consumed by post-crash fire. Authorities closed portions of the airport in the immediate aftermath and emergency services responded to multiple ground casualties. Investigators said they will continue metallurgical analysis of the failed pylon components, review the aircraft’s full maintenance and repair history (including recent work performed by third-party repair facilities), and reconstruct load and stress conditions immediately prior to failure. The agency also is reviewing whether inspection protocols for that specific lug/component were adequate given the airplane’s age and usage cycles.
