A PAL Provincial Airlines de Havilland Dash 8-100, registration C-FDND performing flight PB-1925 from St. John's,NL to Goose Bay,NL (Canada), was climbing through 12,000 feet when the crew received indication that the right hand engine (PW120A) had reverted to manual mode and its ECU (electronic control unit) had dropped offline. The crew continued the flight and was climbing through FL215 when the crew noticed an unexpected yaw and noticed the right hand engine's torque had decreased. Shortly afterward the crew received an oil pressure indication for the right hand engine and the engine was shutting down. The crew completed the engine failure checklist and returned to St. John's for a safe landing.

The Canadian TSB reported maintenance replaced severel components and carried out a test flight. The cause of the power loss is under investigation.
