Probable cause
Power loss due to a failed cracked cylinder. A factor was the lack of suitable terrain for the forced landing.
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 the initial climb after takeoff the pilot experienced a total power loss due to a failure of the number three cylinder. Forced landing terrain impact resulted in damage to the left wing spar and separated the left main landing gear.
