Probable cause

The pilot's inadequate preflight planning and his delayed decision to reverse the airplane's direction.

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 said that he was attempting to cross a high altitude mountain pass, but the airplane's climb capability was diminished due to the prevailing high density altitude. The pilot reversed the direction to begin a circling climb, but the airplane struck a tree. A nearby resident found the pilot and wreckage about 30 hours after the accident. The pilot said that the airplane's engine operated normally and that the airplane did not experience any preimpact malfunctions or failures.

Factual narrative

On August 12, 1996, about 1130 hours Pacific daylight time, an American AA-1, N5616L, crashed in a mountainous area near Rosamond, California. The pilot was conducting a visual flight rules personal flight to Grants Pass, Oregon. The airplane, registered to and operated by the pilot, was destroyed. The certificated private pilot, the sole occupant, sustained serious injuries. The flight departed William J. Fox Airport, Lancaster, California, about 1045 hours.

A deputy sheriff reported that a resident near the accident site found the airplane on August 13, 1996, at 1745 hours.

The pilot said in a telephone interview conducted on August 15, 1996, that he topped off the fuel tanks before departing William J. Fox Airport. He said that the airplane would not clear the mountain pass near Rosamond due to the high density altitude. After realizing that the airplane would not negotiate the mountain pass, he began to circle to gain additional altitude, but the airplane struck a tree. The pilot said that the engine operated normally.
