Sharjah - Khartoum

The Aircraft was operating a flight from Sharjah International Airport, UAE to Khartoum International Airport, Sudan, with a total of six persons on board: three flight crew members (captain, co-pilot, and flight engineer), a ground engineer, and two load masters. All of the crew members sustained fatal injuries due to the high impact forces. Sometime after of liftoff, the core cowls of No. 4 engine separated and collapsed onto the departure runway, consequently No. 4 Engine Pressure Ratio (“EPR”) manifold flex line ruptured leading to erroneous reading on the EPR indicator. The crew interpreted the EPR reading as a failure of No. 4 engine; accordingly they declared engine loss and requested the tower to return to the Airport. The Aircraft went into a right turn, banked and continuously rolled to the right at a high rate, sunk, and impacted the ground with an approximately 90° right wing down attitude.
