FACTORS WERE THE LOSS OF ENGINE POWER DUE TO FUEL STARVATION AS A RESULT OF FUEL LINE BLOCKAGE. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, cruise - fuel system,line - foreign material/substance (contributing factor) - fuel system,line - blocked(total) (contributing factor) - fuel system - starvation (contributing factor) - Forced landing, emergency descent/landing - Hard landing, emergency descent/landing - flare - delayed, pilot in command (cause) - landing gear,tailwheel - separation ## Analysis THE PILOT HAD BEEN AIRBORNE FOR ABOUT 5 MINUTES WHEN A TOTAL LOSS OF ENGINE POWER OCCURRED. HE EXECUTED A FORCED LANDING TO A RECENTLY PLANTED SOYBEAN FIELD. THE AIRPLANE LANDED AND THE TAILWHEEL SEPARATED AND IMPACTED THE RUDDER RESULTING IN STRUCTURAL DAMAGE. A POST-ACCIDENT EXAMINATION OF THE FUEL SYSTEM REVEALED PIECES OF RUBBER IN THE LEFT MAIN TANK, FUEL LINE, AND THE HEADER TANK. ## Factual narrative On June 10, 1995, at 1615 central daylight time, an Ayres Corp S2R-T34, N3105E, was substantially damaged during a forced landing near DeValls Bluff, Arkansas. The commercial pilot was not injured. The aircraft was being operated by Vincent Aviation Inc., under Title 14 CFR Part 137. The flight originated from the Valley Airport, near DeValls Bluff, Arkansas, at 1610. Visual meteorological conditions prevailed for the local aerial application flight and a flight plan was not filed. The pilot stated, during an interview conducted by the investigator-in-charge, that the flight had just departed and was en route to a designated field for spraying. The airplane experienced a total loss of engine power and he executed a forced landing to a recently planted soybean field. The airplane landed and the tailwheel assembly separated from the airframe striking the rudder. The pilot reported that the airplane struck an "unknown object." On the Pilot/Operator Report, the pilot states that "small pieces of rubber [were] found in left main fuel tank, fuel line, and header tank." Sufficient material was found to block the fuel line to the engine, with subsequent total loss of engine power. The source of the rubber particles found in the fuel system is unknown. ## Aircraft - Registration: [N3105E](https://openairdocs.org/aircraft/N3105E), registered now, S/N T34-177, built 1992 (OpenAirDocs) - Reported make and model: AYRES S2R-T34 - Registry model: [Ayres S2R-T34](https://openairdocs.org/model/ayres-s2r-t34) (registry code 0970106) (OpenAirDocs) - Registry engine: [Pratt & Whitney Canada PT6A-6 series](https://openairdocs.org/engine/pratt-whitney-canada-pt6a-6-series) (registry code 52150, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: T34-177 - Engines: P&W PT6A-34 750 horsepower turbo prop - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: Vincent Aviation Inc. - Airworthiness certificate: Special, Restricted (Special) - Last inspection: 100 hour, June 1, 1995, 56 hours before - Departed: PVT ## Flight crew As NTSB recorded them.
