1996-08-02: The crew of N187US
started up the no. 2 engine when a fire ignited because of unburnt fuel in the tail pipe which caused flames to shoot rearward some 8 feet. Maintenance suspect igniter problems. The starting was discontinued. The aircraft is still on the ground in Churchill. UPDATE: Maintenance personel in Calgary traced the engine problem to a fault with the flow divider, which was replaced. The flap problem was traced to a flap control torque limiter which was causing the flaps to lock up. All four flap torque limiters were replaced. The old -9 torque limiters were replaced as per a BAE service letter with an upgraded - 11 torque limiter. The operator has experienced similiar problems with the old -9 torque limiters and will be informing the Civil Aviation Authroirities in Dublin, Ireland.
