During landing, the right main landing gear collapsed after the pilot received no safe indication despite gear appearing extended. Post-incident inspection showed the system functioned properly.

Incident Overview

During the approach to land, the pilot lowered the landing gear but did not receive a locked indication. The landing gear safe indication did not illuminate, prompting the pilot to recycle the landing gear multiple times and perform emergency procedures without success. A low approach over the airport was conducted, during which rescue personnel reported that all three landing gear appeared to be fully extended. However, upon landing on the runway, the right main landing gear collapsed.

Post-Inspection Findings

During aircraft recovery, the right main landing gear was found not locked into position. A mechanic manually pulled the right downlock overcenter mechanism to the full lock position, noting resistance on the downlock. Subsequently, the operator conducted an inspection during which the landing gear system was cycled approximately 5 to 8 times, and the system functioned properly through all cycles.

Emergency Procedures

No further details regarding the specific emergency procedures or actions taken by the pilot were provided in the source.
