Aircraft Accident/Incident Report

Pahrump, Nevada 89102
Sunday, September 21, 2003 11:05 PDT

NTSB Narrative Summary Released at Completion of Accident

The airplane collided with rising terrain while maneuvering to gain altitude shortly after departure. After an uneventful departure, the airplane approached a mountain range, and the pilot opted to execute a 360-degree turn in an effort to gain altitude. While turning, he noticed a significant downdraft, and despite the continuous use of full throttle, the airplane was unable to climb. He attempted to maneuver the airplane to avoid contacting terrain, but the airplane descended about 250 feet per minute and impacted the terrain. The pilot reported no preimpact mechanical malfunctions or failures with the airplane. He thought that the accident could have been prevented if he had maneuvered the airplane away from mountainous terrain. With the temperature and pressure from the nearest reporting station, the density altitude was calculated to be in excess of 4,800 feet.

NTSB Probable Cause Narrative

the pilot's failure to maintain altitude/clearance from the mountainous terrain while maneuvering, which resulted in an in-flight collision with terrain.
