Probable cause
The high cycle fatigue failure of blades on the stage 1 high pressure compressor, which resulted in blade fracture and subsequent internal engine damage and fire.
Sequence of events
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
The air carrier b 737 300 was on takeoff roll, when the aircrew was advised by other airplanes that 'smoke and flames were...coming from the right engine.' The crew aborted the takeoff, stopped the airplane on the runway and ordered an evacuation by the emergency slides. None of the 5 crewmembers nor the 128 passengers were injured. The engine fire was suppressed when the engine was shutdown. The failure was contained to the engine interior. Examination of the engine revealed a high cycle fatigue failure of 2 blades of the stage 1 high pressure compressor.
