NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
According to the flight crew, a loud explosion was heard a few seconds after reaching takeoff power and the takeoff was aborted. While taxiing, the tower informed the flight crew that flames were coming from the no. 4 engine. The aircrew stopped the aircraft and completed the engine fire procedures; however, the airport fire fighters extinguished the fire. An investigation revealed that the no. 4 engine had failed and high energy engine parts were released which resulted in damage to the airframe and the no. 3 engine. Most of the rotating components, forward of 7th stage compressor disk assembly, were released during the explosive failure. An examination of the first stage compressor fan blades showed that the no. 15 first stage fan blade, pn 531601K, had failed from fatigue. The failure occurred 3.2 hrs after overhaul.
