inform Air Traffic Control (ATC) of an engine failure on take off, with the failure in the number one engine. This mistake is indicative of a high stress level within the cockpit, and the breaking down of situational awareness. The air traffic control gave immediate clearance for an emergency return to Karachi, which was acknowledged by the flight crew. This acknowledgment would be the last contact with the stricken aircraft. Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR) data indicates that, after the last radio message, the captain observed the First Officer moving the feather control for engine number two, asking "What are you doing?" The first officer replied that the engine was not feathered properly. It seems likely that the first officer became fixated on this one goal, removing all other situational awareness and to the exclusion of other tasks. By this point, the speed of the aircraft was with increasing pitch attitude and right angle of bank. On the CVR recording further reduction in engine sound was observed. Flight Data Recorder (FDR) information showed that bank angle continually increased. The high stress levels of both pilots resulted in near overload and loss of situational awareness. This meant that the asymmetrical thrust caused by full power application to the functional number one engine and lack of thrust from number two, went unnoticed and was not corrected. Landing gear remained extended and airspeed continued to bleed off, rapidly approaching stalling speed. The cockpit voice recordier noted the beginning of continuous stall warning alerts. The captain is recorded calling out Holy verses from the Quran and "Bismillah (In the name of God)". The ground proximity warning alert, "whoop, whoop", could be heard until the end of the recording. Aircraft The aircraft involved was a twin-turboprop Beechcraft 1900C-1, with Pakistani registration AP-BJD. It was built in 1991 and at the time of the accident had accumulated around 18,000 flight hours. Passengers and crew On board the aircraft were 17 passengers, 2 pilots, 1 technician and 1 security guard. The captain was 53-year-old Naeem-ul-Haq, a Pakistani national born in 1957. He was described as quite religious. He joined the Pakistan Air Force (PAF) Academy in Risalpur in 1977 as trainee pilot. During his service career, he flew various training / fighter and light communication aircraft including MFI-17, T-37, FT-5, FT-6, Piper (Seneca-II), Beech Baron, Y-12, Super King (B-200), Cessna-172 and Cessna-402 aircraft.
