The airplane then landed hard, tearing the right main landing gear off, followed by the nosewheel landing gear. Postaccident examination revealed that the airplane’s fuselage was buckled aft of the main landing gear attachment points and that both tips of the two-bladed propeller were curled aft in a manner consistent with the engine producing power at the time of impact. A witness reported that he heard the sound of metal contacting the ground and observed the airplane dragging its wing. He also observed the main landing gear separate from the airplane and the baggage door open. He did not hear the engine increase power for a go-around. The closest automated weather reporting station, located about 21 miles southeast of the accident site, reported wind from 220 degrees at 8 knots. ## Factual narrative The pilot reported that as he neared for touchdown on runway 32, the airplane encountered a strong gust of wind that pushed him “off the runway”. He stated that he added power, but the engine did not respond. The airplane then landed hard; tearing the right main landing gear off, followed by the nose-wheel landing gear. An examination of the airplane following the accident revealed that the airplane’s fuselage was buckled aft of the main landing gear attachment points and the both tips of the two-bladed propeller were curled aft in a manner consistent with engine power at the time of impact. An individual, who was opening up his hangar, reported that he heard “the sound of metal contacting the ground”; turned and saw the accident airplane dragging its wing. The witness also saw the main landing gear separate from the airplane, and the baggage door, “pop” open. He also added that he did not hear the engine increase power, for a “go-around.” The automated weather reporting station, located about 21 miles southeast of the accident site, reported at 1051 winds at 220 degrees at 8 knots. ## Aircraft - Registration: [N9317G](https://openairdocs.org/deregistered/N9317G-2013-08-06), registration cancelled 2013-08-06, S/N 18260857, built 1971 (OpenAirDocs) - Reported make and model: CESSNA 182P - Registry model: [Cessna 182P](https://openairdocs.org/model/cessna-182p) (registry code 2075816) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18260857 - Airframe hours: 3820 - Engines: CONT MOTOR O-470 SERIES 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Pauls Valley Flyboys LLC - Registered owner: Pauls Valley Flyboys LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, November 17, 2010 - Departed: KPVS, Pauls Valley, OK - Destination: 7F7, Clifton, TX - Airport: 7F7, Clifton Muncipal, runway 32, 3,000 × 50 ft, asphalt ## Flight crew As NTSB recorded them.
