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 pilot apparently had neglected to check his engine oil supply before takeoff since there was no oil in the crankcase at the time of the accident. If five quarts of oil (the amount the pilot reportedly stated was in the engine at takeoff) had leaked out during a five minute flight, then the bottom of the fuselage and the empennage assembly would have been coated with oil. Examination of the aircraft at the accident site showed no signs of an oil leak. The forced landing was made on rough and uneven terrain. After touchdown the nose gear contacted a dirt bank and collapsed.
