The cabin crew of a Jet Airways flight mistook a flickering red light for a fire in the aircraft's engine just before take-off after which the pilot over-reacted and ordered emergency evacuation that resulted in injuries to 25 passengers last month, a probe report has said.
It was found that there was no blaze or even smoke in the cabin of the 9W-2302 Mumbai-Chennai flight, which was then taxiing to the runway and was stopped on the taxiway by the pilot, Directorate General of Civil Aviation (DGCA) said.
The red flicker emanating from the anti-collision light at the bottom of the Boeing 737-800 fuselage created an optical illusion that was mistaken for a fire by the crew members, the final probe report on the August 27 incident at the Mumbai airport said.
The DGCA blamed the captain for "over-reacting" to the situation and ordering evacuation even after all indicators inside the cockpit showed there was no fire. There were 139 passengers on board.
The cabin crew was also blamed for not ensuring proper preparation for evacuation and failing to give proper instructions to the panic-stricken passengers, leading to "chaos inside the cabin".
Four passengers were seriously hurt and 21 received minor injuries as they rushed out through the over-wing exit and jumped off the slide chutes that were deployed and inflated, the 35-page report said.
"It is the illusionary situation due to the red light emanating from the anti-collision light at the bottom of the fuselage in line with the wing, which reflected on the bottom of the wing with quick intermittency," it said.
