Probable cause
The pilot's failure to maintain adequate airspeed, resulting in a stall, hard landing and collapse of the main landing gear.
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 stated that he allowed the approach to the mountaintop to get too low and slow. Just prior to touchdown, one wing stalled, causing the airplane to land hard. One main landing gear collapsed and one wing hit the ground.
