NTSB narrative
The pilot receiving instruction performed a short-field landing to a runway. During the rollout, about 750 ft from the touchdown point, the right main landing gear collapsed, and the right wing contacted the runway, which resulted in substantial damage to the right aileron. A postaccident inspection revealed the right main landing gear brace rib had separated from the wing structure. Examination of the failed components revealed the separation did not occur due to faulty adhesion from the original installation. In addition, an 8- to 10-inch crack was discovered between the upper and lower wing skin bonds to the airplane’s center section spar. That crack would have resulted from some type of force or stress to the airplane, such as a hard landing. However, no hard landings in the airplane had been reported. The airplane had undergone a 100-hour/annual inspection about 3 weeks before the accident, with no reports of damage or faults related to the landing gear. The airplane had been flown for about 35 hours since the inspection by multiple pilots. It is likely that the separation of the right main landing gear support assembly and the crack were initiated by a hard landing that was not reported since the inspection. The condition of the right main landing gear brace rib likely began to deteriorate and the right main landing gear subsequently collapsed during the accident flight.
Probable cause
The failure of the right main landing gear brace rib for reasons that could not be determined based on available information.

- 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, coordinates, cause areas. 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.
