NTSB narrative
The pilot reported the purpose of the flight was to practice maneuvers and perform system checks on the airplane. The pilot extended the landing gear during the flight, and although the gear appeared to be extended the down-and-locked light did not illuminate. The pilot made multiple attempts to lower the gear, including performing the manual extension procedures. The pilot performed a low pass over the airport and was informed by his mechanic that the gear appeared to be extended. During the subsequent landing, the right main landing gear collapsed, resulting in substantial damage to the right horizontal stabilizer and elevator.
Postaccident examination revealed that the left main landing actuator barrel had a longitudinal fracture. Metallurgical examination of the fracture surfaces revealed signatures of overstress. The overstress fracture of the actuator resulted in the failure of the landing gear to fully extend. A functional test and examination of the hydraulic power pack revealed no anomalies that would have precluded normal operation.
Probable cause
An overstress fracture of the left main landing gear actuator, which resulted in the failure of the left main landing gear to fully extend and lock into place.

- 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, 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.
