Electrical System Failure
While on a local flight, the aircraft's electrical charging system failed due to a broken alternator drive belt. The pilot secured all unnecessary electrical equipment and returned to the airport.
Pattern Entry and Communication
Upon entering the traffic pattern, the pilot heard the tower controller ask if the aircraft was 45V and, if so, to rock its wings. The pilot complied and was cleared to land. This was the last radio transmission received by the pilot.
Landing Gear Indication and First Approach
When the pilot extended the landing gear, the gear-down indicator light did not illuminate. Realizing the approach was high and fast, the pilot elected to go around.
Second Approach and Gear Warning
On the second approach, the tower controller attempted to warn the pilot that the landing gear was not down. The pilot reported that he called the tower to inquire about the gear status, and when he did not receive a reply, he assumed the gear was down.
Touchdown and Runway Excursion
The landing gear collapsed on touchdown, and the aircraft ran off the side of the runway. The pilot stated that he did not use the emergency gear extension system.
