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.

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.
