The stall warning horn sounded, and the airplane began to descend to the left. He was able to lower the airplane's nose, and the airplane touched down in the grass area that outlined the left side of the runway surface and then bounced. He cut the engine's power, and the airplane touched down again on the nosewheel and the left main landing gear. The pilot applied right rudder, and he was able to steer the airplane onto the runway and stop. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that during takeoff initial climb, once above the tree line, he felt as though the airplane encountered, "a strong quartering tailwind." The stall warning horn sounded, and the airplane began to descend to the left. He was able to put the airplane's nose down, and the airplane touched down in the grass area that outlined the left side of the runway surface and bounced. He cut the engine's power and the airplane touched down again in the grass area on the left side of the runway and "went onto the nose-wheel and the left main. The pilot applied right rudder and he was able to steer the airplane back onto the runway and stop. The airplane sustained substantial damage to the left wing. The pilot reported that about the time of the accident, the wind at the accident site was calm. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N424BC](https://openairdocs.org/aircraft/N424BC), registered now, S/N 17252171, built 1964 (OpenAirDocs) - Reported make and model: Cessna 172 (F) - 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: 17252171 - Year built: 1964 - Airframe hours: 6191.6 - Engines: Continental O-300-D 145 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Pikeside Flying Club Inc - Registered owner: Pikeside Flying Club Inc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 7, 2019 - Departed: VG18, Bayse, VA - Destination: MRB, Martinsburg, WV - Airport: VG18, Sky Bryce, runway 23, 2,240 × 50 ft, asphalt - Equipment: Stall warning system, Electronic flight bag or handheld device ## Flight crew As NTSB recorded them.
