Aircraft Accident/Incident Report

Markleeville, California 96120
Sunday, October 26, 1997 16:00 PST

NTSB Narrative Summary Released at Completion of Accident

The aircraft was destroyed when it impacted trees in mountainous terrain at about 7,850 feet msl. The density altitude was calculated to be about 8,400 feet. Examination of the trees and the aircraft wreckage disclosed that the aircraft was in near level flight at the time of initial tree contact. The aircraft gross weight at the time of impact was calculated to be about 3900 pounds; the maximum certificated takeoff weight was 3500 pounds. No mechanical malfunction was found in the airframe or the engine. The owner had personally installed a set of amphibious floats and a three-blade propeller. The installation was not inspected or signed off for return to service, and there was no evidence that the weight and balance had been recomputed.

NTSB Probable Cause Narrative

the pilot's improper planning/decision, which resulted in his failure to maintain sufficient altitude or clearance from mountainous terrain. Factors relating to the accident were: the excessive gross weight of the airplane, the high density altitude, and the high (mountainous) terrain.
