The Aircraft Accident Investigation Bureau (AAIB) late Friday published its preliminary report on the fatal Air India plane crash that killed 260 people in Ahmedabad on June 12.
In its 15-page report, AAIB said the wreckage site activities, including drone photography/videography have been completed and the wreckage has been moved to a secure area near the airport.
Here are the key takeaways from the 15-page report:
Wreckage site activities, including drone photography/videography completed; wreckage moved to secure area near Ahmedabad airport
Both engines of crashed Air India plane retrieved; components of interest for further examinations have been identified, quarantined
At this stage of probe, there are no recommended actions to Boeing 787-8 plane operators
Investigation team will examine additional evidence that are being sought from stakeholders
Fuel samples taken from the bowsers and tanks used to refuel the aircraft were tested at the DGCA’s Lab and found satisfactory
Very limited amount of fuel samples could be retrieved from the APU filter and Refuel/Jettison valve of left wing
The testing of these samples will be done at a suitable facility capable of carrying out the test with the limited available quantity
The EAFR data downloaded from forward EAFR is being analyzed in detail
The statement of the witnesses and the surviving passenger have been obtained by the Investigators.
Complete analysis of postmortem reports of the crew and the passengers is being undertaken to corroborate aeromedical findings with the engineering appreciation
As per the EAFR data, the aircraft crossed the take-off decision speed V1 and achieved 153 kts IAS at 08:08:33 UTC. The Vr speed (155 kts) was achieved as per the EAFR at 08:08:35 UTC. The aircraft air/ground sensors transitioned to air mode, consistent with liftoff at 08:08:39 UTC
The aircraft achieved the maximum recorded airspeed of 180 Knots IAS at about 08:08:42 UTC and immediately thereafter, the Engine 1 and Engine 2 fuel cutoff switches transitioned from RUN to CUTOFF position one after another with a time gap of 01 sec
The Engine N1 and N2 began to decrease from their take-off values as the fuel supply to the engines was cut off
In the cockpit voice recording, one of the pilots is heard asking the other why he cut off the fuel, to which the other replied that he did not.
