FACTORS INCLUDE FENCE POSTS STRUCK DURING ROLLOUT AT THE EMERGENCY LANDING SITE. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, cruise - normal - reason for occurrence undetermined (cause) - Forced landing, descent - emergency - On ground/water collision with object, landing - roll - object - fence post (contributing factor) ## 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. ## Aircraft - Registration: [N9768Y](https://openairdocs.org/deregistered/N9768Y-1998-03-17), registration cancelled 1998-03-17, S/N D7154 (OpenAirDocs) - Reported make and model: BEECH P-35 - Registry model: [Beech P35](https://openairdocs.org/model/beech-p35) (registry code 1151530) (OpenAirDocs) - Category: Airplane - Serial number: D-7154 - Airframe hours: 5447 - Engines: CONTINENTAL IO-470N1 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Intermountain Aero, Inc. - Registered owner: Intermountain Aero, Inc. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, October 16, 1993, 230 hours before - Departed: SLC, SALT LAKE CITY, UT - Destination: CYS, CHEYENNE, WY - Flight plan: IFR ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB SEA95LA130](https://openairdocs.org/ntsb/SEA95LA130), Jun 25, 1995: Beech P35 (N9768Y), Challis, ID, destroyed. Probable cause: THE PILOT'S FAILURE TO MAINTAIN AN ADEQUATE SUPPLY OF FUEL FOR THE FLIGHT. THE TERRAIN CONDITION WAS A FACTOR. From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
