The defining event best describes what happened. - [Landing-flare/touchdown: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Boeing A75N1(PT17), 32 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=1380134), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md) ## Analysis The pilot said he was attempting to make a 3-pt. landing in a tailwheel-equipped airplane, when he flared too low, and the airplane bounced. Upon touchdown from the bounce, the airplane entered an unrecoverable yaw moment due to insufficient rudder authority, and the airplane spun 270° off the runway. As the airplane exited the runway, the lower right wing struck the ground resulting in substantial damage. The pilot reported there were no preimpact mechanical malfunctions or failures of the airplane that would have precluded normal operation. ## Aircraft - Registration: [N17N](https://openairdocs.org/aircraft/N17N), registered now, S/N 75-3667, built 1943 (OpenAirDocs) - Reported make and model: BOEING A75N1(PT17) - Registry model: [Boeing A75N1(PT17)](https://openairdocs.org/model/boeing-a75n1-pt17) (registry code 1380134) (OpenAirDocs) - Registry engine: [Lycoming R680](https://openairdocs.org/engine/lycoming-r680) (registry code 41540, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 75-3667 - Year built: 1943 - Airframe hours: 2826 - Engines: Lycoming R-680E3B 240 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, April 24, 2025 - Destination: Same as departure - Airport: BTV, Patrick Leahy Burlington Intl, runway 01/19, 4,112 × 75 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
