Probable cause

A partial blockage of the fuel filter, causing fuel starvation. A contributing factor was the rough terrain.

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
Fuel system,filter - blocked(partial)Cause
Forced landingDescent - emergency
In flight collision with terrain/waterLanding - roll
Terrain condition - rough/unevenFactor

Analysis

While in normal cruise flight, the engine lost power. The pilot made a forced landing next to a dirt road in a canyon. During the landing, the landing gear folded back and buckled the fuselage. Additional tubular structure members were bent. Post-accident examination revealed that fuel flow was restricted due to a partially obstructed fuel filter.

Factual narrative

The pilot was en route from Billings, Montana, to Twin Falls, Idaho. After diverting to Columbus, Montana, and detouring to Cody, Wyoming, the pilot turned towards Dubois, Wyoming. Shortly thereafter the engine lost power. The pilot could see he had 4 gallons of fuel in the right tank and 3 gallons is the left tank. He was able to restart the engine, but it lost power again. The pilot made a forced landing next to a dirt road in a canyon. During the landing, the landing gear folded back and buckled the fuselage. Additional tubular structure members were bent.

The airplane was recovered and taken back to Twin Falls. The pilot's mechanic inspected the airplane and said that fuel flow was restricted due to a partially obstructed fuel filter.
