1997-07-28: The pilot and only occupant of C-FSZT
was returning after a local pleasure flight and a normal landing was accomplished, but as the a/c was rolling out, the landing gear collapsed. Maintenance determined that the gear was down but not locked due to in all likelihood to contaminants in the hydraulic system. The pilot suspects that he did not see the unsafe gear warning light because the landing was made into the setting sun. UPDATE When the pilot had selected gear down for landing, the gear only partially extended, and the manual pump did not function to complete the extension. After the incident, when maintenance lifted the a/c, the gear selector was cycled without result, yet when the manual system was activated, the pump came on and the gear extended fully.
