Air India Express crash: Position of plane's throttle and spoilers leaves experts perplexed

Thiruvananthapuram: Two major contradictory findings during the inspection of the Air India Express aircraft, which crashed in Kozhikode last week, have left experts perplexed.

While the Air India Express plane's cockpit throttle was found to be in the forward position, the spoilers on the wings were partially open. The throttle's forward position indicates the aircraft could have been trying to take off while the position of the spoilers indicates the aircraft was in a braking mode when the accident happened.
Once the engine is put into forward throttle position, the wing spoilers close automatically. The spoilers, which are opened fully when an aircraft touches the runway, are used to slow down the aircraft.

"In the case of the aircraft that met with the accident, the cockpit throttle was in the forward position and, at the same time, the spoilers on the wings were partially open. Chances are there that rescue workers might have held on to various cockpit devices. But one can't change the position of cockpit throttle as it gets jammed in hydraulic pressure soon after the accident," said an Airports Authority of India official. Whether the impact of the crash led to the opening of the spoilers is another question.
