AI117 Archives - Aviation Today

Birmingham, United Kingdom: An Air India Boeing 787‑8 Dreamliner operating flight AI117 from Amritsar, India, to Birmingham, UK, declared a general emergency due to low fuel on the evening of 8 January 2026 after prolonged holding caused by severe winter weather and the temporary closure of Birmingham Airport. The aircraft was safely diverted to London Heathrow Airport where it landed without incident, airline and flight tracking data show. Flight AI117, registration VT‑NAC, was approaching Birmingham in worsening weather as Storm Goretti brought heavy snowfall and dangerously low visibility, leading airport authorities to suspend runway operations. Visibility dipped well below the minima required for a safe landing, forcing the crew to abort the initial approach and enter a holding pattern. With extended time spent circling near the destination, fuel reserves fell toward critical levels. In response, the crew transmitted Squawk 7700 the transponder emergency code indicating a serious onboard issue requiring urgent air traffic control priority signalling a general emergency due to low fuel. This prompted expedited handling and coordination with UK air traffic control for diversion. Air Traffic Control cleared the Boeing 787 to divert to London Heathrow Airport (LHR), chosen for its longer runways and advanced Category III Instrument Landing System (ILS) capable of accommodating landing in degraded weather conditions with enhanced safety margins. The aircraft touched down safely on Heathrow’s runway 09L and subsequently taxied to gate B49 with no reported injuries to passengers or crew. Air India flight operations encountered significant disruption as snow continued to impact Birmingham Airport operations throughout the evening. The airport’s decision to close the runways was part of ongoing safety precautions amid rapid snow accumulation and deteriorating meteorological conditions. A declaration of Squawk 7700, a universal aviation emergency code does not automatically reflect a catastrophic failure; rather, it alerts all air traffic units that the flight requires priority handling due to a critical situation, in this case driven by fuel management considerations following a prolonged holding pattern.

Air India 787 Declares Emergency Over Low Fuel, Safely Diverts To London Heathrow

New Delhi, India: The Directorate General of Civil Aviation (DGCA) has directed Air India to carry out a comprehensive inspection of the Ram Air Turbine (RAT) systems across its entire fleet of Boeing 787 Dreamliners. This action comes after an incident in which the RAT deployed automatically on one of the airline’s aircraft during landing in Birmingham, UK. Boeing has also requested that other 787 operators report any similar occurrences worldwide. The DGCA has specifically instructed Air India to verify the stowage integrity of the RAT in all aircraft where the Power Conditioning Module (PCM) was recently replaced. The Ram Air Turbine serves as an emergency backup system, providing hydraulic and electrical power if the aircraft’s main engines fail. It operates by using the aircraft’s forward motion to spin a small turbine that extends from the fuselage underside. This ensures critical flight control systems and avionics remain operational during emergencies, such as dual-engine failures or complete electrical system loss. Notably, the RAT deployed during the June 2025 crash of Air India flight AI171 after a dual-engine flameout at Ahmedabad, resulting in the loss of 260 lives. The recent directive stems from an October 4, 2025, incident involving Air India flight AI117, flying from Amritsar (ATQ) to Birmingham (BHX), where the RAT deployed automatically at around 500 feet during descent. The aircraft landed safely, with all electrical and hydraulic systems reportedly functioning normally. According to the DGCA advisory, “Air India has been advised to review the work package of ‘D’ Check for the actions required in view of the change of PCM module, for any discrepancies.” The regulator noted that the RAT is rarely activated during routine operations and is typically reserved for critical failures, making any uncommanded deployment a serious concern. Air India confirmed that despite the unexpected RAT deployment, all onboard systems were stable throughout the flight. Following the incident, the Federation of Indian Pilots (FIP) requested the DGCA to inspect the electrical systems on all Boeing 787s operating in India. In a letter, FIP President GS Randhawa highlighted that the Aircraft Health Monitoring (AHM) system had detected a fault in the Bus Power Control Unit (BPCU), which could have triggered the RAT deployment. The BPCU is essential for managing electrical power distribution, and any malfunction may activate backup systems. FIP emphasized that this incident points to potential systemic electrical vulnerabilities in the Boeing 787 and called for thorough inspections of all aircraft in the country. Civil Aviation Minister Ram Mohan Naidu stated, “The DGCA is already on the job. Once we have more details, we will coordinate with the relevant stakeholders to ensure preventive measures are implemented and such incidents are avoided in the future.” The DGCA has extended its review beyond Air India, requesting Boeing to provide a detailed report on preventive measures and to share information on similar uncommanded RAT deployments globally in recent years. This aims to identify any recurring patterns and enhance the safety protocols of the 787 fleet.

DGCA Orders Air India To Reinspect RAT Systems On All 787s After Uncommanded Deploy

New Delhi, India: The Directorate General of Civil Aviation (DGCA) has directed Air India to carry out a comprehensive inspection

New Delhi, India: An Air India Boeing 787-8 Dreamliner operating flight AI117 from Amritsar to Birmingham experienced an uncommanded deployment of its Ram Air Turbine (RAT) during final approach on October 4, raising fresh concerns over the safety of the carrier’s widebody fleet. The aircraft, registered VT-ANO, landed safely in Birmingham, though its return service to Delhi was cancelled and the jet was grounded for detailed inspections. India’s aviation regulator, the Directorate General of Civil Aviation (DGCA), has launched a probe into the incident. According to officials, all electrical and hydraulic systems remained stable despite the RAT deployment. Routine maintenance checks recommended by Boeing were performed on the aircraft, and no discrepancies were reported. The DGCA has stated that the jet will be cleared to return to service only after thorough inspections are completed. The Federation of Indian Pilots (FIP) President G S Randhawa has formally written to the DGCA, warning that limiting post-crash inspections to fuel control switches is insufficient. Instead, the group has urged regulators to expand checks to the electrical systems of all Boeing 787 aircraft in India. The FIP highlighted that the aircraft’s Aircraft Health Monitoring (AHM) system flagged a fault in the Bus Power Control Unit (BPCU), which manages the electrical power distribution and may have triggered the RAT deployment. The union stressed that this mirrors deeper systemic issues rather than isolated switch malfunctions.
