Analysis

The pilot experienced a loss of power while in cruise flight at 11000 feet, while on an IFR flight. He attempted remedial action, including selecting another fuel tank, checking magnetos, and otherwise attempted restarting the engine. During landing roll on the dirt road selected for the forced landing, the aircraft impacted railroad ties used as fence posts, causing substantial damage. After the accident, the aircraft engine was run, a different wing was installed, and the aircraft was test flown with no observed anomalies.

Factual narrative

On July 20, 1994, at 2033 mountain daylight time, a Beech P-35, N9768Y, lost power and collided with terrain during a forced landing thirteen miles southwest of Laramie, Wyoming. Visual meteorological conditions prevailed at the time and an IFR flight plan was filed. The pilot and two passengers were not injured and the airplane was substantially damaged.

While in cruise flight at 11000 feet, the aircraft's engine lost power. The pilot declared an emergency, attempted to restart the engine, and performed a forced landing, attempting to land on an old dirt road. On rollout the airplane struck a fence post in the middle of the road, and it was substantially damaged.

After the accident, an FAA inspector inspected all fuel, ignition and induction systems, and the engine was run. The damaged wing was replaced and the aircraft was test flown with no discrepancies noted.
