UPDATE from Aircraft Maintenance & Manufacturing: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. On the take-off roll from Iqaluit, NU, the crew of C-FERJ observed that the #2 engine failed to produce full power. The take-off was rejected and the aircraft returned to the main ramp without further incident. Upon further investigation, on the ramp, the crew determined that the #2 engine failed to respond to any thrust inputs and remained in Ground Idle. The #2 engine full authority digital engine control (FADEC) system was not operating normally and was Minimum Equipment Listed (MELd), allowing the aircraft to return to Yellowknife, NT for maintenance. Company maintenance in Yellowknife confirmed the fault and replaced the #2 engine FADEC module, conducted the necessary checks, which cleared the MEL. The aircraft was returned to service and there were no further reported incidents.

A Provincial Airlines de Havilland DHC-8-311 (C-GHRJ/PVL928) from Deer Lake, NL (CYDF) to St. Johns, NL (CYYT) on terminal ramp mistakenly activated its emergency locator transmitter (ELT) signal outside testing parameters.

A Central Mountain Air de Havilland DHC-8-102 (C-GMJJ/GLR748) from Fort St. John, BC (CYXJ) to Prince George, BC (CYXS) was taxiing on the ramp, for Runway 21 for departure, at the time.

A call was received from Pacific radio advising that a Kan-Arm Contracting Ltd. Piper PA-31 (C-GDJR) on a training flight from Chilliwack, BC (CYCW) was inbound to Abbotsford, BC (CYXX) with a total electrical failure and possibly no landing gear. The pilot gave their intentions and estimated time of arrival (ETA) at CYXX by telephone. Aircraft Rescue and Fire Fighting (ARFF) and 911 were put on standby. The aircraft landed safely with minimal operational impact. A Swoop Inc. Boeing 737-800 (WSW107) on a flight from Hamilton, ON (CYHM) to Abbotsford, BC (CYXX) was moved to a different approach and some VFR aircraft held out on the ground.
UPDATE TSB Report #A19P0167: C-GDJR, a privately operated Piper Navajo PA-31-310 aircraft took off from Chilliwack, (CYCW) BC on a training flight with two pilots on board. When the gear was selected up, the crew observed a gear unlocked indication. The gear was cycled and a gear down and safe indication was achieved. The crews intent was to return to CYCW, but when they selected flaps down there was no movement of the flaps and the landing gear down and locked lights faded out. The crew made the decision to divert to Abbotsford, (CYXX) BC because it had a long runway and emergency equipment. During the diversion to CYXX, all electrical power was lost and communications equipment failed. Using a cell phone, the crew contacted the Kamloops Flight Service Station and declared a Mayday. They explained the situation, stated their intention was to land in CYXX, and requested to have ARFF standing by. On short final, enough electrical power returned for the crew to see they had a landing gear down and locked indication. The aircraft landed uneventfully and taxied to the ramp. Maintenance determined via a continuity check that the RH alternator field wire had an intermittent fault caused by a broken wire and / or a bad terminal crimp. They also found the LH engine noise filter had been removed from the alternator circuit, and wire terminals were taped with automotive electrical tape.
