The pilot was using S-turns as he taxied, in an attempt to see ahead of the airplane's large engine and cowling. While taxiing, the pilot of the warbird failed to see a stationary and occupied motor glider. The warbird's right wheel ran over the wing of the motor glider, resulting in minor damage to the warbird, and substantial damage to the motor glider. ## Analysis (aircraft 1) A North American SNJ-5 tailwheel warbird airplane, was taxiing on the ramp after landing.

The Grob, which was stationary but with its engine running, was substantially damaged. Visual meteorological conditions prevailed at the time of the accident. Both flights were personal and were being conducted under the provisions of Title 14 Code of Federal Regulations Part 91 without a flight plan. The pilots on board both airplanes were not injured. The flight of the SNJ-5 originated at 1445 from Centennial Airport (APA), Englewood, Colorado. The flight of the Grob had not yet originated. According to the pilot of the SNJ-5, he landed on runway 8L. He exited the runway on taxiway Echo, merged onto taxiway Foxtrot, and taxied south across runway 8R and onto the ramp. From there, he taxied southwest towards taxiway Alpha and some private hangars, located in the southwest corner of the ramp. The pilot used S-turns as he taxied. The SNJ-5's right wheel ran over the right wing of the Grob. The SNJ-5 sustained minor damage to its right wing tip, leading edge and right aileron. According to the pilot of the Grob, he had stopped and was obtaining taxi clearance and ATIS information when the SNJ-5's main landing gear rolled over his right wing. Damage to the Grob included a broken right wing spar. The outer portion of the right wing and the leading edge of the vertical stabilizer were crushed. The wooden propeller of the motor glider was also damaged. ## Aircraft 1 - Registration: [N12KY](https://openairdocs.org/aircraft/N12KY), registered now, S/N 90995, built 1943 (OpenAirDocs) - Reported make and model: North American SNJ-5 - Registry model: [North American SNJ-5](https://openairdocs.org/model/north-american-snj-5) (registry code 6400418) (OpenAirDocs) - Registry engine: [Pratt & Whitney R1340 series](https://openairdocs.org/engine/pratt-whitney-r1340-series) (registry code 52016, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 90995 - Airframe hours: 5208 - Engines: Pratt & Whitney R-1340-AN-1 600 horsepower reciprocating - Damage: Minor damage - Flight: Personal, Part 91 - Operator: Richard Wells - Registered owner: North American War Birds, LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, November 1, 2006, 14 hours before - Departed: APA, Englewood, CO - Destination: PUB, Pueblo, CO - Airport: PUB, Pueblo Municipal ## Aircraft 2 - Registration: [N39810](https://openairdocs.org/aircraft/N39810), registered now, S/N 3813, built 1983 (OpenAirDocs) - Reported make and model: Burkhart Grob Flugzeugbau G103 Twin Astir - Registry model: [Burkhart Grob Flugzeugbau G103 TWIN ASTIR](https://openairdocs.org/model/burkhart-grob-flugzeugbau-g103-twin-astir) (registry code 1660202) (OpenAirDocs) - Registry engine: [Bombardier ROTAX (ALL)](https://openairdocs.org/engine/bombardier-rotax-all) (registry code 09050, reciprocating) (OpenAirDocs) - Category: Airplane - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Clifford L.
