NTSB narrative
During an instructional flight, the pilot receiving instruction performed an emergency landing gear extension; however, the left main gear did not extend despite multiple attempts, and the instructor chose to land with the gear retracted, resulting in substantial damage to the fuselage. Examination revealed that the left main landing gear pivot assembly shaft had fracture-separated near the pivot housing. Metallurgical examination of the fracture surfaces revealed signatures of overstress. The overstress fracture of the pivot assembly resulted in the failure of the left landing gear to fully extend.
Probable cause
An overstress fracture of the left main landing gear pivot assembly, 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.
