She made five uneventful short field landings and was going to switch to soft field landings. While on approach, she noticed the airplane was left of centerline therefore during touchdown, she applied right rudder and right aileron. The airplane turned right, then turned left, and was heading off the runway. She then decided to abort the landing; however, the nose wheel was not straight and when she applied full power, the airplane veered off the left side of the runway and toward a row of hangars. The airplane struck the door of a hangar with the right wing, propeller, and then the left wing before coming to a stop on the ramp, which resulted in substantial damage to the wings, fuselage, and engine mounts. The owner reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N772J](https://openairdocs.org/deregistered/N772J-2023-01-14), registration cancelled 2023-01-14, S/N 366, built 2016 (OpenAirDocs) - Reported make and model: JABIRU AIRCRAFT PTY LTD J170-D - Registry model: [Jabiru Aircraft PTY J170-D](https://openairdocs.org/model/jabiru-aircraft-pty-j170-d) (registry code 06001BB) (OpenAirDocs) - Registry engine: [Jabiru 2200A](https://openairdocs.org/engine/jabiru-2200a) (registry code 34803, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 366 - Year built: 2016 - Airframe hours: 236 - Engines: JABIRU 2200A 85 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Airworthiness certificate: Special, Special light-sport (Special) - Airport: OKV, Winchester Rgnl, runway 32, 5,498 × 100 ft, asphalt - Equipment: Stall warning system, Electronic primary flight display, Electronic multifunction display, ADS-B ## Flight crew As NTSB recorded them.
