$Kelsey, United States: The National Transportation Safety Board (NTSB) has released its final investigation report into the severe turbulence incident involving United Airlines Flight 1890, concluding that air traffic control failed to disseminate a critical pilot weather report that could have reduced the severity of the event. The Board said the aircraft encountered an unanticipated region of moderate-to-severe turbulence during descent into Newark Liberty International Airport, resulting in serious injuries to three flight attendants, while 277 other occupants were not injured. The incident occurred on February 10, 2024, when a Boeing 777-222ER, registered N788UA, was operating a scheduled domestic service from Los Angeles International Airport to Newark under Part 121 operations. While descending through approximately 21,500 feet (FL215) in instrument meteorological conditions, the aircraft encountered a localized pocket of turbulence that produced rapid vertical accelerations between 0.55 g and +1.82 g over several seconds. The sudden motion lifted unsecured crew members from the cabin floor and threw them into the ceiling and surrounding structures. Three flight attendants sustained serious injuries, including spinal fractures, a shattered femur, head trauma, and intracranial bleeding. Despite the injuries, the flight crew maintained control of the aircraft and continued to a safe landing at Newark, where emergency medical services met the aircraft at the gate. According to the report, the flight crew conducted standard preflight and in-flight turbulence assessments using Weather Services International (WSI) and SkyPath tools. Both systems showed only light to moderate turbulence along the planned route, and the onboard weather radar did not display any significant convective activity. Dispatch had advised the crew earlier in the flight that only one moderate turbulence report had been received from another regional jet descending into Newark, and no further warnings were issued as the aircraft approached the terminal area. Approximately three minutes before the incident, another aircraft, ACA548, reported moderate turbulence to Boston Air Route Traffic Control Center (ZBW ARTCC) while flying ahead of United 1890 on the same route near the Hancock VOR. That report was not acknowledged or passed on to the following aircraft. The NTSB determined that the probable cause of the accident was the aircraft’s encounter with a localized region of moderate-to-severe turbulence associated with strong upper-level wind shear and convective cloud tops. Contributing to the severity of the outcome, the Board found that air traffic control failed to disseminate the earlier pilot weather report, which reduced the flight crew’s situational awareness and limited their opportunity to seat cabin crew and secure the cabin before the encounter. Investigators stated that the controller handling the sector did not hear the initial turbulence report and therefore did not relay it, despite Federal Aviation Administration procedures requiring the solicitation and distribution of pilot weather reports during significant turbulence conditions. Meteorological analysis showed the presence of a cold front, embedded thunderstorms, and a strong jet stream with winds exceeding 110 knots near 21,000 feet, creating wind shear and clear-air turbulence at the tops of cloud layers. Satellite imagery and model data confirmed that turbulence conditions were present in the exact altitude band flown by the aircraft. The NTSB concluded that the flight crew followed proper procedures and used all available tools, but the most relevant real-time warning the pilot report issued minutes earlier was not provided to them, making the turbulence effectively unanticipated.$

Galveston, United States: New federal investigative findings reveal critical communication misunderstandings and extremely limited visibility as major factors immediately preceding the December 22, 2025, crash of a Mexican Navy medical flight in Galveston Bay that killed six people and left two seriously injured, according to the preliminary report released by the U.S. National Transportation Safety Board (NTSB). The Beechcraft B300 aircraft, registered ANX1209 and operated by the Mexican Navy, was on a humanitarian medical mission coordinated with the Michou y Mau Foundation. The flight was transporting a severely burned pediatric patient from Mérida, Mexico, to Shriners Children’s Hospital in Galveston, Texas, when it crashed into West Bay during its approach to Scholes International Airport shortly before 3:15 p.m. local time. According to the NTSB preliminary report, Houston Approach Control cleared the flight crew for an RNAV (GPS-based) approach to Runway 14 but did not clear the aircraft to land. The flight crew’s initial readback mistakenly stated they were “cleared to land,” prompting controllers to twice clarify that the aircraft was cleared only for the approach and not for landing. Controllers then directed the crew to contact the tower. Despite repeated clarifications, the crew’s responses indicated persistent misunderstanding. During the final stages of the approach, air traffic controllers issued multiple low-altitude alerts, but received no further communication from the flight crew before radar contact was lost. The preliminary report and weather observations confirmed dense fog and severely restricted visibility during the aircraft’s final descent. Controllers advised the crew that cloud ceilings near the airport were approximately 300 feet, a condition that significantly limits visual reference and places heavy reliance on instrument procedures. Local weather data and witness accounts indicate visibility at times was as low as approximately a quarter mile with heavy sea fog common along the Texas Gulf Coast under certain conditions further complicating the approach. The aircraft impacted the waters of West Galveston Bay approximately half a mile from the shoreline. Six occupants including the pilot, co-pilot, two flight crew members and two passengers were fatally injured. Two passengers, reported to be a flight nurse and the mother of the pediatric patient, survived with serious injuries. Search and rescue operations immediately following the crash involved the U.S. Coast Guard, Texas Department of Public Safety, Galveston County Sheriff’s Office and local first responders. The wreckage was located in shallow water, facilitating recovery efforts. The NTSB’s preliminary report is part of an ongoing investigation to determine all contributing factors. These factual reports do not assign probable cause but document the circumstances surrounding the accident based on available data, including air traffic control communications and radar information. Federal investigators will continue to analyze cockpit voice recordings, flight data, maintenance records and meteorological data. A final report typically released 12–24 months after an accident will include a probable cause determination and safety recommendations aimed at preventing similar tragedies.

Dhana, India: A preliminary investigation report released by India’s Aircraft Accident Investigation Bureau (AAIB) has detailed how a Cessna 172S training aircraft operated by Chimes Aviation Pvt. Ltd. crashed during a go-around at Dhana Airstrip in Madhya Pradesh on December 10, 2025, leaving a 22-year-old trainee pilot with minor injuries and destroying the aircraft. The aircraft, registered VT-CAZ, was returning from a solo cross-country training flight when the accident occurred at 08:43 UTC (2:13 pm IST) while attempting to land on Runway 35. According to the AAIB, the trainee pilot made an initial approach but aborted the landing due to instability. During a second approach, the aircraft floated beyond the touchdown zone, prompting air traffic control to order another go-around. As the pilot advanced power, the aircraft pitched up abruptly, rolled left, and lost control, crashing onto the unpaved ground beside the runway. The pilot managed to unbuckle and escape from the wreckage. No fire broke out, but the aircraft sustained substantial damage, including shattered propeller blades, collapsed nose landing gear, broken windscreens, and bent wings. The trainee pilot held a valid Student Pilot License, had 74.5 flying hours, all on the Cessna 172, and had been medically cleared and well rested before the flight. A breath-analyser test conducted before departure was also normal. The aircraft, built in 2014, had a valid airworthiness certificate and had completed a 50-hour maintenance inspection just one day before the accident, on 9 December 2025, with no defects reported. Weather conditions were also favourable, with clear skies, 6 km visibility, and light winds, ruling out bad weather as a contributing factor. AAIB teams have secured the wreckage and recovered Garmin G1000 flight data, CCTV recordings, and engine and airframe components for detailed analysis. Fuel and oil samples are also being tested. Because the aircraft and key components were manufactured overseas, the US National Transportation Safety Board (NTSB) and Germany’s Federal Bureau of Aircraft Accident Investigation (BFU) have been notified and are assisting the Indian investigation. The AAIB stressed that the findings are preliminary and aimed only at preventing future accidents, not assigning blame. A final report will determine the root cause of the loss of control during the go-around.

Zurich, Switzerland: Swiss International Air Lines has come under withering scrutiny after a federal safety investigation found the carrier failed to act on an eight-year-old aircraft safety warning, contributing to a serious in-flight pressurisation failure on a transatlantic flight in 2024. The Swiss Transportation Safety Investigation Board (STSB) released its final report this month, saying the airline’s inaction was “incomprehensible from a safety perspective,” after a faulty component on an Airbus A330 forced pilots to execute an emergency descent and divert back to Zurich Airport in September 2024. On September 13, 2024, an Airbus A330 registered HB-JHI operating flight LX18 from Zurich to Newark Liberty International Airport encountered a critical pressurisation problem shortly after take-off. During ascent, the aircraft began losing cabin pressure due to a defective component within the pressurisation system, a “skin check valve” which failed to seal properly. Although both outflow valves indicated “fully closed,” the aircraft was unable to build sufficient differential cabin pressure. According to the STSB report, cockpit instruments showed inadequate pressurisation despite normal system settings. Cockpit crews donned oxygen masks, manually deployed passenger oxygen systems, and initiated an emergency descent at approximately 5,000 feet per minute before returning safely to Zurich. All 205 passengers and 12 crew members evacuated normally, and no injuries were reported. The STSB’s investigation found that the root cause of the pressurisation failure was a mechanically compromised skin check valve that had not been replaced in over eight years, despite Airbus issuing a service bulletin in 2016 recommending its earliest possible replacement and regular inspections every 24 months. The manufacturer’s bulletin identified that the original valve design was prone to hinge wear, vibration damage and spring failure, all of which could lead to air loss and potential depressurisation events during flight. European aviation regulators and maintenance manuals require that such service bulletins be carefully considered by operators to ensure fleet safety. Investigators noted that the defective valve on the SWISS aircraft remained in service far beyond its recommended inspection and replacement interval, even after being removed and inspected multiple times without upgrading to the redesigned part. The report concluded that this prolonged delay in corrective maintenance directly contributed to the in-flight incident. In its final recommendations, the STSB urged the European Union Aviation Safety Agency (EASA) to mandate the skin check valve replacement on all applicable Airbus A330 and A340 aircraft via a formal Airworthiness Directive rather than relying on voluntary compliance with service bulletins. The board cautioned that gradual decompression events can elude crew awareness in early stages, increasing risk if they occur at cruising altitudes. SWISS International Air Lines, part of the Lufthansa Group, had not issued an immediate public response, and the airline had not yet provided a formal comment in response to the STSB’s final report.

Jakarta, Indonesia: Indonesian authorities confirmed on Friday that all 10 victims from the fatal crash of an Indonesia Air Transport (IAT) ATR 42-500 turboprop aircraft have been recovered, concluding a seven-day search and rescue operation on the steep slopes of Mount Bulusaraung in South Sulawesi. The aircraft, registered PK-THT, disappeared from radar on January 17 while on a maritime surveillance mission for the Ministry of Marine Affairs and Fisheries. It was en route from Adisutjipto Airport, Yogyakarta, to Sultan Hasanuddin International Airport in Makassar when contact was lost during its final approach. Rescue teams, comprising personnel from the National Search and Rescue Agency (Basarnas), military, police, and volunteers, faced rugged terrain, steep ravines, dense fog, and volatile weather throughout the operation. Bodies were found in scattered locations on the mountainside and transported to forensic specialists in Makassar for Disaster Victim Identification (DVI) procedures. By Friday morning, the 10th and final victim had been located, marking the official end of the recovery phase. Authorities expressed condolences to the families of the victims and reiterated support for identification and repatriation processes. A key breakthrough in the investigation came with the recovery of the aircraft’s cockpit voice recorder (CVR) and flight data recorder (FDR) from the wreckage. A joint SAR team located both units intact in the tail section of the aircraft on January 21, despite adverse weather delaying initial access. Following extraction from the crash site, the devices were secured and transported to a checkpoint in Tompobulu village, before being handed over to the National Transportation Safety Committee (KNKT), Indonesia’s official air accident investigation authority. Basarnas Chief Air Marshal Mohammad Syafii confirmed that the recorders will be analyzed to reconstruct the sequence of events leading up to the crash. Earlier in the response, the KNKT classified the crash as a Controlled Flight Into Terrain (CFIT) incident, indicating the aircraft was under control when it impacted the mountain slope although classification does not imply pilot intent or assign fault. The investigation team has not yet publicly disclosed a definitive cause, citing the ongoing analysis of flight recorder data and other evidence. The ATR 42-500 turboprop was conducting a routine surveillance mission in support of fisheries and maritime resource monitoring when it vanished. Initial reports indicated 10 people on board, including seven crew members and three passengers from the Ministry of Marine Affairs and Fisheries. The mountainous crash zone spans portions of Maros and Pangkajene and Islands regencies, complicating early rescue efforts and driving a multi-agency coordinated response.

Portland, United States: A federal court in Portland, Oregon, has sentenced 58-year-old New Delhi businessman Sanjay Kaushik to 30 months in federal prison for conspiring to illegally export sensitive aviation components from the United States to Russia in violation of U.S. export control laws. The sentence was handed down on January 15, 2026, and is to be followed by 36 months of supervised release. Kaushik, who was arrested in Miami, Florida, on October 17, 2024, remained in U.S. custody throughout the legal proceedings and pleaded guilty on October 9, 2025, to one count of conspiracy relating to the sale and attempted export of aviation technology with dual civilian and military applications to Russian end users. According to the official U.S. In a Department of Justice (DOJ) press release, Kaushik and his co-conspirators began their activities in September 2023 by purchasing aviation technology and components, including an Attitude and Heading Reference System (AHRS) , a navigation and flight-control device from an Oregon-based supplier. Such pieces of technology are subject to strict export licensing under the U.S. Export Control Reform Act and the Export Administration Regulations due to their potential military use and strategic importance. To dodge these controls, Kaushik’s group falsely asserted that the AHRS and other materials were destined for use in civilian helicopters in India, operated by his India-based company. Prosecutors established that the ultimate goal was to ship the technology through India to Russian end users, a move that would have directly violated U.S. sanctions and national security safeguards. Federal authorities intervened before the shipment could leave U.S. soil and detained the AHRS, effectively blocking the illegal export. U.S. Attorney for the District of Oregon Scott E. Bradford described the operation as “a calculated, profit-driven scheme involving repeated transactions, substantial gains, and coordination with foreign co-conspirators, including sanctioned Russian entities.” Assistant Attorney General for National Security John A. Eisenberg emphasized that individuals who seek to circumvent export laws, especially for technologies with potential military applications, “will be prosecuted to the fullest extent of the law.” Kaushik faced a federal grand jury indictment returned on November 20, 2024, on three counts related to conspiracy, attempted illegal export, and making false statements in connection with an export. At sentencing, the court took into account his guilty plea and cooperation, but highlighted the serious national security implications of the conduct. Legal analysts say the case underscores the rigorous enforcement of U.S. export control regulations, particularly amid heightened global tensions and sanctions against Russia. The DOJ and related enforcement agencies have signaled that they will continue to pursue individuals and entities that attempt to bypass controls designed to prevent sensitive technologies from reaching prohibited destinations. Kaushik’s sentence of 30 months, while significantly less than the maximum statutory penalty that could have exceeded several years, reflects both the gravity of the offence and the discretion exercised by the court. Upon release, he will be subject to three years of supervised freedom under U.S. oversight.
