1996-07-04: The aircraft arrived at Thunder Bay with the pilot and one passenger onboard. While taxiing off runway 07/25 onto taxiway Bravo, the aircraft's master warning light illuminated. The pilot immediately shut down both engines. The aircraft however, had not quite cleared the runway which caused 4 flights to be delayed. The pilot was unable to restart the engines and eventually was towed to the Imperial Oil hangar. Maintenance inspected the aircraft. The engines were started and shut down a number of times without difficulty. It was determined that the gear air to ground squat switch had not engaged which meant that the engines could not be started on the ground. (Safety feature) It was suggested that while the aircraft was towed the microswitch was realigned. A new air to ground squat and micro switch are being installed at Thunder Bay.
