The airplane became airborne again, and the pilot initiated a go-around. During the go-around, the airplane entered a left bank and the pilot attempted to correct; however, the landing gear contacted the ground between the runway and taxiway, collapsing the nose and right main landing gear, and the airplane came to rest in the grass area adjacent to the taxiway. The airplane’s fuselage sustained substantial damage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N689PG](https://openairdocs.org/aircraft/N689PG), registered now, S/N 1889, built 2008 (OpenAirDocs) - Reported make and model: CIRRUS DESIGN CORP SR20 - Registry model: [Cirrus Design SR20](https://openairdocs.org/model/cirrus-design-sr20) (registry code 2130000) (OpenAirDocs) - Registry engine: [Continental IO-360-ES](https://openairdocs.org/engine/continental-io-360-es) (registry code 17160, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 1889 - Year built: 2008 - Airframe hours: 3247.6 - Engines: Continental IO-360-ES 200 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Texas Skies Flight School - Registered owner: Sky Flea Aero LLC - Airworthiness certificate: Standard, Normal - Departed: 5C1, Boerne, TX - Airport: 5C1, Boerne Stage Airfield, runway 17, 5,006 × 60 ft, asphalt - Equipment: Stall warning system, Electronic primary flight display, ADS-B, Airframe parachute, Auto-pilot, Electronic multifunction display ## 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.
