Incident at YELLOWKNIFE NT (CYZF)

Summary

2001-04-27: The crew of C-GSYN, a Beech King Air, was inbound to Yellowknife on a flight from Gjoa Haven, when they reported having shut down one engine. C-GSYN landed without further incident at 1823Z with CFR on standby.
2001-04-30: UPDATE TSB reported that the Adlair Aviation Beech 100 was enroute from Gjoa Haven to Yellowknife when an engine fire warning light flickered for the number two engine, a Pratt & Whitney PT6A-28. Engine power was reduced and then the light came on intermittently, then came on steady. The engine was shut down. The aircraft landed, without incident at Yellowknife with ERS on standby. The reason for the fire warning light is unknown.
2001-05-01: UPDATE Maintenance and Manufacturing reported that company maintenance inspected the # 2 engine area and the fire warning system. There was no evidence of any type of fire having taken place. All of the connectors in the wiring system of the fire warning system were inspected and cleaned, the system checked serviceable repeatedly. There is speculation that the fire warning may have been set off by sunlight entering around the exhaust cut-out of the forward upper engine cowling. There are shields installed in this area to preclude the entrance of suns rays, past experience has indicated that occasionally they will enter. An SDR has been submitted and the A/C has been returned to service.
