Air India Flight Uses Emergency Engine Similar to Crashed AI 171; Pilot Body Says Fuel Switch Check Insufficient

Air India Flight Deploys Emergency Engine Similar to Crashed AI 171; Pilot Association Criticizes Limited Safety Checks
Emergency Deployment of Ram Air Turbine Raises Safety Concerns
On October 4, an Air India Boeing 787 operating the Amritsar–Birmingham route experienced a critical incident when its Ram Air Turbine (RAT) unexpectedly deployed during the final approach phase. The aircraft managed to land safely, but the event has reignited apprehensions regarding the safety of Boeing 787 aircraft, drawing direct comparisons to the tragic AI 171 crash in June that claimed 260 lives, including 19 on the ground.
The RAT is an emergency device designed to generate power through wind speed in the event of dual-engine failure or loss of electrical and hydraulic systems. In both the recent incident and the AI 171 crash, the RAT’s deployment was a central feature. The Federation of Indian Pilots (FIP) reported that the Aircraft Health Monitoring (AHM) system on the Birmingham flight detected a fault in the Bus Power Control Unit (BPCU), which likely triggered the RAT’s automatic deployment at an altitude of approximately 500 feet.
Calls for Comprehensive Inspections and Regulatory Scrutiny
In response to the incident, FIP President G. S. Randhawa addressed a letter to the Directorate General of Civil Aviation (DGCA), urging a thorough inspection of all Boeing 787 electrical systems operating in India. Randhawa criticized the regulator’s response following the AI 171 crash as inadequate, noting that only the fuel control switches of Air India’s 787 fleet were examined. He emphasized the need for a more exhaustive review to prevent future occurrences.
The AI 171 crash on June 12, involving a flight from Ahmedabad to London Gatwick, remains under investigation by India’s Aircraft Accident Investigation Bureau (AAIB). Preliminary findings indicated that the engine fuel control switches were inadvertently cut off seconds after takeoff, resulting in a catastrophic loss of thrust. Cockpit voice recordings revealed confusion among the pilots regarding the switch-off, with neither accepting responsibility.
Families of the victims have initiated legal action against Boeing and Honeywell, alleging that defective fuel switches and a flawed locking mechanism contributed to the crash by allowing the switches to be unintentionally turned off during critical moments. However, the U.S. Federal Aviation Administration has stated that these switches do not appear to have caused the accident.
The AAIB’s preliminary report also highlighted that the aircraft had not undergone all recommended inspections and that the throttle control module, including the fuel switches, had been replaced in 2019 and 2023. The Supreme Court of India has expressed strong criticism of the handling of the crash investigation, describing the premature release of the preliminary report by aviation authorities as “irresponsible.”
Ongoing Investigations and Safety Implications
The Federation of Indian Pilots continues to stress that multiple electrical-related incidents involving Boeing 787 aircraft necessitate urgent, fleet-wide inspections. The pilots’ association warned that without comprehensive checks, similar incidents could recur, posing significant safety risks.
As investigations proceed, the aviation community and regulatory bodies remain focused on assessing whether current safety protocols and inspections are sufficient to prevent further emergencies involving Boeing 787 aircraft in India.
