Incident Summary
During cruise, the pilot detected an odor suspected to be from overheated electrical wiring. In response, the pilot diverted to a nearby airport for a precautionary landing. After establishing communication with the tower, the pilot shut down all electrical power.
Approach and Landing
Prior to landing, the pilot restored electrical power to lower the landing gear using normal procedures. The pilot assumed the gear was down and locked, but did not obtain a positive indication. The pilot did not use the hand crank to verify the gear was locked. Upon touchdown, the landing gear collapsed.
Investigation Findings
The investigation noted that the pilot did not use the hand crank to confirm the gear was locked before landing. The gear collapse occurred because the gear was not properly locked in the down position.
