The pilot had not yet retracted his flaps and lost directional control of the airplane. The airplane departed the left side of the runway, traversed through the grass, and came to rest in a swale, resulting in substantial damage to the fuselage and engine mount. The pilot did not report any mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N8210R](https://openairdocs.org/aircraft/N8210R), registered now, S/N 30421, built 1972 (OpenAirDocs) - Reported make and model: BELLANCA 17-30A - Registry model: [Bellanca 17-30A](https://openairdocs.org/model/bellanca-17-30a) (registry code 1220433) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 30421 - Year built: 1972 - Airframe hours: 3538 - Engines: Continental IO-520-K1A 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 7, 2023 - Departed: KDTL, Detroit Lakes, MN - Destination: Same as departure - Airport: XVG, Longville Muni, runway 31, 3,549 × 75 ft, asphalt - Equipment: Auto-pilot, Electronic flight bag or handheld device ## Flight crew As NTSB recorded them.
