Incident at 50 miles N MONTRÉAL / PIERRE ELLIOTT TRUDEAU INTL QC (CYUL)

Update TSB #A15Q0121: A Propair Beech A100 (PRO102/C-FDOU) took off from Chibougamau/Chapais to conduct a medical flight to Montréal/Pierre Elliott Trudeau. The crew declared an emergency because of a problem with the landing gear. After flying over the flight service station (FSS) at Mirabel (CYMX) and conducting usage checks, PRO102 obtained confirmation that the gear was extended. The crew cancelled the emergency and the aircraft landed at Montréal/Pierre Elliott Trudeau without further incident. Examination of the aircraft revealed that a right main gear power control unit (PCU) leak (Avia Design ADI-7999-003-3) caused a hydraulics and aircraft wheel retraction system failure.
A Propair Beech 100 (PRO102) MEDEVAC, from Chibougamau (CYMT), QC, to Montréal (CYUL), QC, declared an emergency because of a landing gear problem. The aircraft conducted a low altitude pass at Mirabel (CYMX), QC, so that the flight service station (FSS) could visually confirm the position of the gears. After conducting a few manoeuvres and checks in flight, the pilot received confirmation that the wheels were extended (three green lights). PRO102 cancelled the emergency and landed without incident at 1855Z.
Update (Aircraft Maintenance): A civil aviation safety inspector (CASI) looked into this incident. The CASI communicated with the operator to obtain more information. The necessary repairs and tests were undertaken and the aircraft was returned to service. The CASI was satisfied with the information provided and indicated that no other follow-up by Transport Canada was required for the time being.

Incident at TERRACE BC (CYXT)

Shortly after departing Terrace, BC (CYXT) for Vancouver, BC (CYVR), a Hawkair Aviation de Havilland DHC 8-102 (C-FDNG/ HA113) reported an unspecified indicator issue to Vancouver area control centre (ACC), cancelled IFR and indicated returning to CYXT. HA113 landed without incident. No impact on operations.
Update from Maintenance & Manufacturing: On departure from Terrace, BC (CYXT) the left hand (LH) attitude director indicator (ADI) toppled. This indicated a failure of the LH attitude and heading reference system (AHRS) computer. Due to the availability of parts the crew elected to return to CYXT for maintenance. Shortly after heading back the ADI came to life and all indications were normal. It was elected to replace the AHRS computer as the failure modes are such that they will start to occasionally fail and reset until they fail completely. After the AHRS computer was replaced function checks were done and the system was checked serviceable. The aircraft has had no further issues.

Incident at GANDER INTL NL (CYQX)

CME602, Beech 200, enroute from St. John?s (CYYT) to Gander (CYQX), at 21:33Z, conducted a missed approach due an indication and proceeded to Deer Lake (CYDF). The aircraft landed in Deer Lake at 22:07Z. Nil TSB.
UPDATE Maintenance & Manufacturing: While on approach to Gander the flight experienced a glide slope issue on the Number two Attitude Direction Indicator (ADI). When they saw a discrepancy between the Number 1 Flight Director command bars and the Number 2 glide slope they decided to overshoot and continue on to Deer Lake. The decision to overshoot Gander was also weather related. The glide slope functioned properly in Deer Lake and in Halifax; however, the command bars were off which they snagged in Halifax. The avionics shop could not fault the ADI or the Glide slope. They replaced the Number 1 ADI for the command bar issue. Both ILS systems were checked and tested normally.

Incident at GOOSE BAY NL (CYYR)

TSB - A04A0004: The Labrador Airways Cessna Caravan C208, operating as LAL523 on a flight from Nain to Natuashish, was cruising at 3000ft ASL when the pilot the pilot noticed the aircraft was climbing slowly with the auto pilot on. The auto pilot was selected off and the aircraft abruptly nosed up. Elevator trim was not effective in trimming the aircraft and the pilot had to apply excessive control column force to keep the aircraft in level flight. The pilot advised he was diverting to Goose Bay and a short time later he declared an emergency. The aircraft landed at 1104 ADT without incident. Maintenance personnel inspected elevator trim system and found the presence of moisture inside of both elevator trim actuator shafts. The actuators were disassembled, cleaned and regreased. The trim system then function checked normally and the aircraft was returned to service. The company is considering increasing the lubrication frequency for the trim actuators. This aircraft operates in a cold climate and is frequently cold soaked before being moved in to the hangar. This is conducive to condensation and moisture accumulation over time that can later freeze and hinder trim movement.
