Primary finding
Probable cause
The pilot's inability to maintain a climb after an attempted takeoff in high density altitude conditions, which resulted in a forced landing on a road and subsequent landing gear collapse.
Investigator assessment
Analysis narrative
The pilot was departing from an airport where the density altitude was 7,700 feet. While departing with a slight left quartering, the airplane lifted off from the runway near the mid field point and began slowly climbing. Crossing the end of the runway, the airplane yawed and then began to lose altitude. After the airplane exited the airport boundary, which was on a plateau, it continued to lose altitude and descended down the sloped terrain. Unable to gain airspeed or maintain altitude, the pilot initiated a forced landing to a road. During the landing, the right main and nose landing gear collapsed. The right wing and lower fuselage were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
