Probable cause

The engine power loss due to fuel contamination, and the lack of suitable terrain on which to land.

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.

Loss of engine power(total) - nonmechanicalCruise - normal
Fluid,fuel - contaminationCause
In flight collision with terrain/waterDescent - uncontrolled
Light(s) - none suitableCause

Analysis

The pilot stated the engine quit while flying into a canyon at about 600 ft AGL. After switching to another tank, it restarted, but the descent could not be arrested before crashing into the trees. The pilot thought the engine quit from contamination in the tank, which was at a very low level. The airplane was destroyed by post-impact fire.
