What happened
On April 10, 2010, an ACT-Havoyollari Airbus A300B4-200, operating flight DHX-521, was performing a takeoff from Bahrain International Airport in Muharraq, Bahrain. The aircraft, registration TC-ACE, was a freight flight destined for Bagram Air Base, Afghanistan, carrying 7 crew members.
During the takeoff roll, the No. 2 engine suffered an uncontained low pressure turbine disk failure. The failure was accompanied by a loud bang and the engine burst into flames, resulting in the release of debris and fluids onto the runway. The crew performed a high-speed rejected takeoff and activated the fire suppression system. The aircraft came to a safe stop and the crew evacuated the plane. There were no injuries reported.
The investigation
The Kingdom of Bahrain did not conduct an investigation into the incident. The engine was transported to MyTechnic MRO at Sabiable Gökçen Airport in Istanbul, Turkey. Components recovered from the runway—including the LPT stage (S)3 and S4 rotor disks, the turbine rear frame, the exhaust nozzle, and the centerbody—were shipped alongside the engine.
Between June 15 and June 26, 2010, the Dirección General de Aeronáutica Civil (DGAC) of Turkey performed an analytical disassembly inspection of the engine, with the United States participating as the State of Design and Manufacture.
