He then elected to fly to the “Lynx Strip” and flew across the runway and did not notice any “significant [wind]” at low altitude or on the water of a nearby pond. He performed two passes over the runway from different directions and again noted the wind was “negligible.” He performed two landings to the north then a full stop landing to the south. He departed and performed a “left traffic teardrop” for a final landing to the north. Either at touchdown or just moments before he felt drag on the right wing and realized the right wingtip was, “in the small Black Spruce [trees] to the right of the runway.” He applied left rudder and some aileron input to correct back to center, but the drag on the right wing increased. The airplane made an arc to the right and contact black spruce trees off the right side of the runway coming to rest upright perpendicular to the runway facing east. According to the airplane manufacturer, the total wingspan of the airplane was about 36 ft. Postaccident examination of the airplane revealed damage to the leading edges of both wings which was greater than 10% of the total wingspan; therefore, the damage was considered substantial. ## Aircraft - Registration: [N178TT](https://openairdocs.org/aircraft/N178TT), registered now, S/N 278-78, built 1978 (OpenAirDocs) - Reported make and model: BELLANCA 8GCBC (NO SERIES) - Registry model: [Bellanca 8GCBC](https://openairdocs.org/model/bellanca-8gcbc) (registry code 1220803) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 278-78 - Year built: 1978 - Airframe hours: 2209.8 - Engines: Lycoming O-360-C2E 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Lockwood Kurt G - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 24, 2021 - Airport: None, Lynx Strip, runway 36, 660 × 50 ft, grass/turf - Equipment: Stall warning system, Handheld GPS ## Flight crew As NTSB recorded them.

Aircraft landed right of centerline on off-airport area, impacting brush, causing aircraft to arc other wing into brush. From the NTSB's public API. 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. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
