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

During a practice run-on landing the aircraft started to vibrate violently and an almost simultaneous fire occurred. Both pilots and an eyewitness stated that the run on landing was very smooth. Both pilots stated that something mechanical let loose during the landing. Since the destruction of the aircraft by the fire was so severe, examination and metallurgical analysis was not conclusive.
