A North Cariboo Air de Havilland Dash 8-300, registration C-GLWN performing flight NCB-4098 from Calgary,AB to Primrose,AB (Canada) with 3 crew, was climbing through about 16700 feet out of Calgary when the crew received indications of the left hand engine (PW123) torque rolling back. No additional indications, changes of parameters or cautions occurred. The crew declared emergency, worked the related checklists and diverted to Edmonton International Airport,AB (Canada) for a safe landing.
The Canadian TSB reported maintenance determined after studying the FDR data, that the #1 Engine Electronic Controller had an intermittent fault. The EEC was replaced, the engine was checked without any further anomaly and the aircraft was returned to service.
