What happened
During the approach phase of flight, the pilot attempted to extend the landing gear by moving the handle to the down position. However, the left main landing gear down indicator light failed to illuminate. After notifying air traffic control, the pilot performed a go-around and attempted to cycle the landing gear handle again, but the indication remained unchanged.
In an attempt to verify the status of the gear, the pilot reduced engine power during the final approach to check for the presence of an unsafe gear audible warning. Because the warning did not sound, the pilot decided to proceed with the landing despite the indicator light failure. The pilot requested that tower controllers visually confirm the position of the gear, and the controllers reported that the gear appeared to be down.
Upon touchdown, the left main landing gear collapsed. The aircraft subsequently departed the side of the runway and struck a taxiway sign, causing substantial damage to the airplane. There were no injuries reported in this incident.
