Probable cause

The collapse of the left main landing gear due to a broken gear tooth in the landing gear actuator.

NTSB narrative

The pilot reported that, when he put the landing gear handle down, the left main landing gear did not indicate that it was locked. He cycled the landing gear several times in an attempt to get it down and locked before landing. During the landing, the left main landing gear collapsed, and the left horizontal stabilizer and elevator were substantially damaged. Disassembly of the left main landing gear actuator revealed that a gear tooth from the piston assembly had broken off, which prevented the left main landing gear from locking in the down position. The reason for the gear tooth failure could not be determined.
