As the airplane began to move from the ramp, the leading edge of the right wing struck a parked and unoccupied airplane. The right wing received damage that required the removal of the right wing leading edge from wing station 100 to 190, removal and replacement of a forward wing stringer, and installation of new leading edge wing skin. ## Factual narrative On September 17, 1999, about 1440 Alaska daylight time, a wheel equipped Cessna 207 airplane, N36CF, sustained substantial damage after colliding with a parked airplane at the Bethel Airport, Bethel, Alaska. The accident airplane was being operated as a visual flight rules positioning flight under Title 14, CFR Part 91, when the accident occurred. The airplane was operated by Yute Air Alaska Inc., Anchorage, Alaska. The commercial certificated pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed. VFR company flight following procedures were in effect. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on September 17, 1999, the company Director of Operations reported the pilot was starting to taxi from the company ramp. The pilot was positioning the airplane to Akiachak, Alaska, to begin an air taxi charter flight. As the pilot began to taxi away from the ramp, the leading edge of the right wing struck a parked and unoccupied, Cessna 207 airplane, N7594I. On September 28, 1999, a Federal Aviation Administration (FAA) operations inspector, Anchorage Flight Standards District Office (FSDO), notified the NTSB IIC that the repair to the right wing entailed the following: Removal of the right wing leading edge from wing station 100 to 190, removal and replacement of a forward wing stringer, and installation of new leading edge wing skin. ## Aircraft - Registration: [N36CF](https://openairdocs.org/deregistered/N36CF-2012-05-07), registration cancelled 2012-05-07, S/N 20700269, 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: 20700269 - Airframe hours: 25976 - Engines: Continental IO-520-F 300 horsepower reciprocating - Damage: Substantial damage - Flight: Positioning, Part 91 - Operator: Yute Air Alaska Inc. - Registered owner: M And M Leasing - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, August 20, 1999, 92 hours before - Destination: Z13, AKIACHAK, AK - Flight plan: Company VFR - Airport: PABE, Bethel ## Flight crew As NTSB recorded them.
