AT 1237 THE PLT ADVISED WORLAND FSS THAT THE ENG HAD LOST POWER AND HE WAS GOING DOWN. THE PLT SAID THAT ON FINAL APCH HE HAD TO PULL UP TO AVOID POWER LINES. THE ACFT STALLED AND NOSED INTO GROUND. THE CRASH SITE WAS 5 MI EAST OF GREYBULL, WY. THE FUEL SELECTOR VALVE WAS POSITIONED ON THE LEFT TANK. THE LEFT TANK WAS FOUND TO BE EMPTY AND THE RIGHT TANK WAS FULL. THE ACFT HAS 2 FUEL TANKS, EACH HOLDS 46 GALS (44 USABLE). THE DISTANCE FROM AURORA TO GREYBULL IS APRX 354 NAUTICAL MI. TIME EN ROUTE WAS APRX 2 HRS, 37 MIN. THIS COMPUTES TO AVERAGE 136.2 KTS GROUND SPEED. PERFORMANCE CHART FOR 8000 FOOT PRESSURE ALT GIVES A NUMBER OF POWER SETTINGS THAT WILL YIELD AVERAGE FUEL CONSUMPTION RATES BETWEEN 10.3 AND 17.8 GPH AND AVERAGE TRUE AIRSPEED BETWEEN 111 AND 151 KTS. ## Aircraft - Registration: [N6277Z](https://openairdocs.org/aircraft/N6277Z), registered now, S/N U20606211, built 1979 (OpenAirDocs) - Reported make and model: CESSNA TU206G - Registry model: [Cessna TU206G](https://openairdocs.org/model/cessna-tu206g) (registry code 2073357) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: U20606211 - Airframe hours: 26 - Engines: CONTINENTAL TSIO-520-M 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Michael A.
