- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Loss of control on ground
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The pilot reported that on downwind for landing on runway 13, he observed that the wind tetrahedron indicated a west wind and the windsock was flapping around. While on base leg, the pilot experienced slight turbulence. The pilot reported that on touchdown, there were some "sudden gusts," and as he added normal braking, the right tire failed, which caused a loss of directional control and subsequent skid. The left main landing gear collapsed, and the airplane slid to a stop on the taxiway. The aft fuselage was substantially damaged. A witness reported that the airplane touched down about halfway down the runway with an estimated 15 knot tailwind. The pilot applied the brakes and the airplane skidded down the runway. Shortly after, the right tire "blew out," and the airplane continued to slide sideways down the runway. Subsequently, the left main landing gear collapsed, and the left wing and tail struck the runway. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot's failure to maintain control of the airplane during the landing roll, which resulted in a landing gear collapse.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
