The defining event best describes what happened. - [Landing: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Piper PA-18-135, 8 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=7101820), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md) ## Analysis The flight instructor reported that during landing, the upwind wing raised, and power was applied for a go-around. The nose was lowered, and aileron was applied into the wind, but there was insufficient airspeed to sustain flight. The airplane settled and contacted a drainage ditch, which resulted in substantial damage to both wings. The instructor reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N1136](https://openairdocs.org/aircraft/N1136), registered now, S/N 18-4041 (OpenAirDocs) - Reported make and model: PIPER PA-18-135 - Registry model: [Piper PA-18-135](https://openairdocs.org/model/piper-pa-18-135) (registry code 7101820) (OpenAirDocs) - Registry engine: [Lycoming 0-290 series](https://openairdocs.org/engine/lycoming-0-290-series) (registry code 41506, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 18-4041 - Year built: 1953 - Airframe hours: 3642 - Engines: LYCOMING 0-320 SERIES 140 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 29, 2022 - Departed: 5MN1, Nary, MN - Destination: Same as departure - Airport: Y49, Walker Muni, runway 33, 3,220 × 75 ft, asphalt ## Flight crew As NTSB recorded them.
