After establishing the airplane on a 1-mile final approach to the runway, the pilot initiated a sideslip to maintain runway centerline. After touching down about 800 feet beyond the runway threshold, a gust of wind struck the airplane and it veered off the runway. The airplane crossed a taxiway then struck a concrete culvert before flipping over and coming to rest inverted. The pilot stated that once the aircraft veered left, he could not recover. Both of the airplane’s wings and the empennage were substantially damaged during the accident. The pilot reported that there were no preimpact mechanical malfunctions or failures of the airplane that would have precluded normal operation. ## Aircraft - Registration: [N6327F](https://openairdocs.org/deregistered/N6327F-2022-09-03), registration cancelled 2022-09-03, S/N 18264160, built 1975 (OpenAirDocs) - Reported make and model: CESSNA 182 (P) - 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: 18264160 - Year built: 1975 - Airframe hours: 1967.9 - Engines: CONT MOTOR O-470 SERIES 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Baldrick Aviation Partnership LLC - Registered owner: Baldrick Aviation Partnership LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 5, 2020, 47 hours before - Departed: DYL, Doylestown, PA - Destination: Same as departure - Airport: N47, Pottstown Muni, runway 26, 2,704 × 75 ft, asphalt - Equipment: Handheld GPS, Auto-pilot, ADS-B, Stall warning system ## Flight crew As NTSB recorded them.
