Probable cause

The failure of the turbocharger scavenging pump resulting in the total failure of the engine, and the pilot's failure to compensate for wind conditions that led him to over fly the runway during his forced landing. Factors were the pilot's diverted attention due to smoke in the cockpit, and the tailwind weather condition.

Analysis

The pilot said that the engine began to run rough, and he could smell smoke in the cockpit. He said that the smoke got worse, and he shut off the master switch. He saw the airport, headed for it, and his engine power began to fail. He attempted to land on runway 16, with a 22 knot gusting to 26 knot tailwind, but was too high. The pilot said he turned right, to approximately 180 degrees, to miss some buildings. He landed approximately 1,000 feet from the departure end of the runway in scrub-covered terrain. The airplane impacted a berm, and nosed over. The airplane's vertical stabilizer, left wing, and fuselage were damaged. Postaccident examination of the engine by a mechanic revealed that the turbocharger's oil scavenger pump had failed. The mechanic said that the scavenger pump's failure would cause the engine's oil to pass overboard.

Factual narrative

On May 31, 2000, approximately 1650 mountain daylight time, a Cessna TR182, N738FN, was substantially damaged during a forced landing to Milford Municipal Airport, Milford, Utah. The private pilot, sole occupant in the airplane, received minor injuries. The airplane was being operated by the pilot under Title 14 CFR Part 91. Visual meteorological conditions prevailed for the cross-country flight that originated from Cedar City, Utah, approximately 50 minutes before the accident. No flight plan had been filed.
