Incident at WINNIPEG / JAMES ARMSTRONG RICHARDSON INTL MB (CYWG)
2003-03-10: The crew of CAV 7519, a Saab 340, rejected their takeoff on Runway 31 at Winnipeg and taxied back to the apron. The nature of the problem was unspecified, however, TSB will contact the company.
2003-03-12: UPDATE TSB reported that the crew of a Calm Air Saab 340 rejected take-off on Runway 31 at the Winnipeg International airport and the aircraft taxied back to the terminal under its own power. The crew reported that when they advanced the power levers they did not get a proper left engine Automatic Power Reserve (APR) indication and rejected the takeoff prior to 80 knots. The aircraft departed shortly thereafter under its MEL with the APR placarded INOP. Maintenance personnel later discovered that a power lever microswitch in the center console was frozen. The console was heated and the microswitch functioned normally. It is believed that the microswitch froze as a result of the aircraft having been cold soaked prior to the flight.
2003-03-11: UPDATE Maintenance and Manufacturing reported that this was the first flight of the day for the a/c after a cold night on the ramp. During the takeoff roll, the APR (automatic power reserve) light came on. The problem was traced to a microswitch in the center power lever console for the APR system. The a/c had not been sufficiently pre-heated prior to takeoff. Heat was placed in the cockpit and the problem has not recurred.
