The pilot also noted that the windsock on the northern end of the airport was limp. During landing, as the main wheels touched down, the pilot applied slight nose forward pressure on the yoke. Shortly thereafter, the right wing lifted rapidly and the pilot added right aileron and increased power in an attempt to regain control and perform a go-around. The airplane started to veer to the left side of the runway and the pilot reduced the power. The airplane exited the left side of the runway, proceeded through a fence, and entered a ditch. The airplane slid along the ditch until it came to rest perpendicular to the runway. The pilot reported no mechanical failures or malfunctions with the airframe or engine prior to the accident. ## Factual narrative The pilot reported that while nearing the destination airport he listened to the automated weather which indicated wind from the north at 3-4 knots. The pilot also noted that the windsock on the northern end of the airport was “limp.” During landing, as the main wheels touched down, the pilot applied “slight” nose forward pressure on the yoke. Shortly thereafter, the right wing lifted rapidly and the pilot added right aileron and power to attempt to regain control and perform a go-around. The airplane started to veer to the left side of the runway and the pilot reduced the power. The airplane exited the left side of the runway, proceeded through a fence, and entered a ditch. The airplane slid along the ditch until it came to rest perpendicular to the runway. During the accident sequence, the airplane’s fuselage and wings were substantially damaged. The pilot reported no mechanical failures or malfunctions with the airframe or engine prior to the accident. ## Aircraft - Registration: [N230SS](https://openairdocs.org/deregistered/N230SS-2014-11-25), registration cancelled 2014-11-25, S/N 108-4193, built 1948 (OpenAirDocs) - Reported make and model: STINSON 108-3 - Registry model: [Stinson 108-3](https://openairdocs.org/model/stinson-108-3) (registry code 9230408) (OpenAirDocs) - Registry engine: [Continental O-470R](https://openairdocs.org/engine/continental-o-470r) (registry code 17071, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 108-4193 - Airframe hours: 961 - Engines: Teledyne Continental Motors O-470 Series 230 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: David J.

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.
