Aircraft damage: Substantial
Category:Accident
Location:Garfield County, north of Glenwood Springs, CO -   United States of America
Phase: Landing
Nature:Private
Departure airport:Provo, UT (PVU)
Destination airport:Colo. Springs, CO (FLY)
Investigating agency: NTSB
Narrative:
The private pilot stated that, shortly after reaching cruise altitude on the cross-country flight, engine cylinder head and exhaust gas temperatures displayed on the multifunction display (MFD) became erratic. Since the pilot had previously experienced trouble with the MFD sensory input unit, he reverted to monitoring the analog gauges, which were registering normal temperatures. Shortly thereafter, the engine backfired and the pilot sensed a partial loss of engine power, followed by a further decrease in power. Unable to maintain altitude and realizing he would be unable to reach any nearby airports, the pilot made a forced landing on a snow-covered plateau, resulting in substantial damage.

Postaccident examination of the airframe revealed large quantities of water in the wing tanks, which likely accumulated during the time the airplane was on the mountain before recovery and during storage. The airframe fuel gascolator contained a large amount of debris and rust. The gascolator was replaced with a surrogate unit, and a subsequent test run of the engine revealed no anomalies. It is likely that the loss of engine power was the result of fuel contamination; however, the source of the contaminants could not be determined, because fuel samples from the departure airport contained no contaminants.


Probable Cause: A partial loss of engine power due to fuel contamination from an undetermined source.
