He shut down the engine and, after getting out of the airplane, he observed that the left wing of a Piper had collided with the left side of the Cessna’s rudder and vertical stabilizer, tipping the vertical stabilizer to the right and twisting and buckling the fuselage. The pilot of the Piper reported that, while he was taxiing to get fuel with no intent for flight, he saw the tail of the Cessna directly in front of him. He applied right brake action and swiveled his airplane to avoid directly hitting the Cessna with the propeller. The pilot added that he had no idea why he was unable to see the Cessna in time to avoid the collision. ## Factual narrative While standing in the run-up area waiting to taxi onto the runway, the pilot of the Cessna heard a loud noise and felt movement of his airplane. He shut the engine down and got out to see that the left wing of a tail-wheel equipped Piper had collided with the left side of the Cessna’s rudder and vertical stabilizer. The pilot of the Piper reported that he was taxiing to get fuel, with no intent for flight, and as he turned off the taxiway to the run up pad in order to run the engine prior to getting fuel, he saw the tail of the Cessna directly in front of him. He applied right brake action and swiveled his aircraft to avoid a direct collision with his propeller. The pilot added that he had no idea of why he wasn’t able to see the Cessna in time to avoid the collision. ## Aircraft - Registration: [N8713U](https://openairdocs.org/deregistered/N8713U-2018-03-07), registration cancelled 2018-03-07, S/N 17252617, built 1965 (OpenAirDocs) - Reported make and model: CESSNA 172F - Registry model: [Cessna 172F](https://openairdocs.org/model/cessna-172f) (registry code 2072414) (OpenAirDocs) - Registry engine: [Continental 0-300 series](https://openairdocs.org/engine/continental-0-300-series) (registry code 17022, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17252617 - Airframe hours: 3558 - Engines: Continental O-300 165 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Jeffery L Winters - Registered owner: Jeffery L or Calinda S Winters - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 19, 2012, 71 hours before - Departed: MAN, Nampa, ID - Destination: MAN, Nampa, ID - Airport: MAN, Nampa Airport, runway 11, asphalt ## Flight crew As NTSB recorded them.
