The aircraft took off from runway 25L at 07:04 hours. After takeoff the aircraft experienced abnormal operation of engine no. 2 and the flight crew decided to turn back to Karachi Airport. The controller cleared the flight for a right hand downwind for runway 25L.
Meanwhile the crew were having difficulties dealing with the emergency situation. They failed to retract the undercarriage and the captain mistakenly referred to engine no. 1 as the one that was experiencing performance issues, while both crew knew this was engine no.2. According to the cockpit voice recorder the flight officer attempted to manually feather the no.2 propeller without the captain's instructions and before the aircraft had reached an altitude of 400 feet per recommended procedures.
While joining the right hand downwind for 25L the right hand bank angle increased to a maximum of 52°. Speed decreased and the aircraft was continuously losing altitude under stalled state. The aircraft impacted terrain at 07:05.
Factors leading to the Accident
The aircraft accident took place as a result of combination of various factors which directly and indirectly contributed towards the causation of accident.
1. The primary cause of accident includes, inappropriate skill level of Captain to handle abnormal operation of engine No 2 just after takeoff, failure of cockpit crew to raise the landing gears after experiencing the engine anomaly, execution of remedial actions by FO before the attainment of minimum safe altitude of 400 ft AGL resulted in non conformance and non compliance of cockpit crew to OEM recommended procedures to handle such situations.
2. The lack of situational awareness and CRM failure directly contributed towards ineffective management of the flight deck by the cockpit crew.
3. The contributory factors include inadequate cockpit crew simulator training monitoring mechanism both at operator and CAA Pakistan levels in respect of correlation of previous / current performance and skill level of cockpit crew during the simulator training sessions along with absence of conduct of recurrent / refresher simulator training between two annual simulator checks in accordance with ICAO Annex-6 guidelines and CAA Pakistan (applicable ANOs) requirements for specific type of aircraft in a year.
