Overview of the Air India Ahmedabad Crash

The Aircraft Accident Investigation Bureau (AAIB) has released a preliminary report on the tragic Air India plane crash in Ahmedabad. The incident involved a Boeing 787-8 Dreamliner, which was operating as AI171, bound for London’s Gatwick Airport. The aircraft crashed shortly after takeoff, resulting in the deaths of 241 passengers and crew members, with only one survivor. The crash also claimed the lives of 19 people on the ground, bringing the total fatalities to 260. This event is considered one of the deadliest aviation disasters in India’s history.

Critical Findings from the AAIB Report

The AAIB’s 15-page report highlights several crucial findings. Both engines of the aircraft shut down mid-air within seconds after takeoff due to the fuel cutoff switches being moved from RUN to CUTOFF in rapid succession. This action led to an immediate loss of power. Cockpit audio recordings revealed a conversation between the pilots, where one questioned why the engines were cut off, and the other denied doing so.

Emergency Measures and Attempts to Recover Control

In response to the engine failure, the Ram Air Turbine (RAT), a device designed to provide emergency hydraulic power, was automatically deployed. CCTV footage from the airport confirmed this deployment shortly after takeoff. Despite efforts by the pilots to restart the engines, only partial recovery of engine 1 was achieved, while engine 2 failed to restart before impact. The aircraft remained airborne for just 32 seconds before crashing into a nearby building.

Technical and Environmental Conditions

The investigation found that thrust levers were at idle, although black box data indicated that takeoff thrust was still engaged, suggesting a possible disconnect or failure. Fuel tests showed no contamination, and environmental conditions were favorable with clear skies and light winds. The flap settings and landing gear positions were normal for takeoff.

Pilot Credentials and Potential Oversights

The report confirmed that both pilots were experienced, medically fit, and well-rested. No immediate evidence of sabotage was found; however, an existing FAA advisory regarding a potential flaw in fuel switches had not been addressed by Air India inspections. The aircraft was within its weight and balance limits, with no dangerous goods onboard.

Implications for Aviation Safety

This preliminary report underscores the importance of addressing known technical advisories and ensuring rigorous inspection protocols to prevent similar tragedies in the future. The findings will likely prompt further investigations into maintenance practices and safety measures within the aviation industry.
