The sightseeing flight operated under the provisions of 14 CFR Part 91, with no flight plan filed. Visual weather conditions prevailed at the time of the accident. The airplane sustained substantial damage, and the six persons on board the airplane were not injured. The flight departed First Flight Airstrip, Kill Devil Hills, North Carolina, at 1355 hours. According to the operator, the pilot was conducting a routine sightseeing flight when he experienced a loss of engine power. The pilot established an emergency descent to a county road. During the forced landing, the airplane struck an automobile and a road sign. An examination of the engine assembly disclosed that the mixture control cable rod end had separated at the carburetor, and the mixture control lever on the carburetor was in the fuel cutoff position. During the functional check of the engine, the engine operated normally. ## Aircraft - Registration: [N1670U](https://openairdocs.org/deregistered/N1670U-2003-04-14), registration cancelled 2003-04-14, S/N 20700270, built 1974 (OpenAirDocs) - Reported make and model: CESSNA 207 - Registry model: [Cessna 207](https://openairdocs.org/model/cessna-207) (registry code 2073602) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 00270 - Airframe hours: 18000 - Engines: CONTINENTAL IO-520 300 horsepower reciprocating - Damage: Substantial damage - Flight: Part 91 - Registered owner: Kitty Hawk Aero Tours - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, August 30, 1994, 80 hours before - Departed: FFA, KILL DEVIL HILL, NC - Destination: FAA ## Flight crew As NTSB recorded them.
