GOA JET AIRWAY 27 DECEMBER 2016 ACCIDENT OCCURRED DUE TO CREWS FAULT: REPORTS

The Indian investigators have resolute that Boeing 737-800, skidded off the runway in Dabolim as crew did not allow the aircraft’s engines to stabilise their thrust before take-off.

At 5AM, on 27th December 2016 Mumbai bound flight suffered a runway excursion during take-off from Goa.  Around 15  out 161 on board passengers had suffered injuries. While, the airport remained closed for couple of hours on that day. Directorate General of Civil Aviation had initiated an detailed inquiry into the incident.

According to reports the aircraft, operated by Jet Airways and bound for Mumbai, had lined up on runway 26 after backtracking and performing a 180° turn. India’s accident inquiry committee states that the crew advanced the thrust levers to the 40% setting. But while the left-hand engine was running at 40% of N1, the right-hand one had only reached 28% when the captain commanded full take-off thrust. This failure to allow the CFM International CFM56 engines to stabilise led to a thrust imbalance as the aircraft accelerated.

Within 10-12 seconds the aircraft departed the paved surface and the crew attempted to brake and use rudder and nose-wheel steering to correct its course.  The jet left the runway and turned in a wide right-hand arc, eventually coming to rest facing the opposite direction and 219m from the edge of the runway. It collided with a path-indicator lamp as well as a 2.3m pillar during the excursion, and the aircraft suffered substantial engine, undercarriage and fuselage damage.

Investigators state that the rejected take-off manoeuvre was conducted “incorrectly”, pointing out that only the right-hand thrust lever was retarded to idle thrust.

Investigators state that first officers should be “more assertive” with regard to adherence to standard operating procedures. The inquiry also says a call-out, confirming stabilisation of engine power, should be introduced after initial thrust application.   —- Inputs Flight Gobal
