C-FUJE, an Embraer ERJ 170-200 aircraft operated by Sky Regional Airlines, was conducting flight SKV7675 from Boston/General Edward Lawrence Logan Intl (KBOS), MA to Toronto/Lester B. Pearson Intl (CYYZ), ON. Just before activating the flap lever during the descent into CYYZ, the flight crew observed a SLAT FAIL EICAS message.

The flight crew interrupted the approach and requested vectors in order to complete the checklist. Subsequently, ARFF was requested on stand
by for the flapless landing, and the aircraft landed on Runway 05 without incident. The aircraft stopped on the taxiway for inspection, and was authorized to taxi to the gate, followed by ARFF behind.

The operator’s maintenance inspected the aircraft and determined that the number 2 Slat/Flap Actuator Control Electronics (SF-ACE) needed to be replaced.

C-GKUK, a Bombardier DHC-8-400 aircraft operated by Jazz Aviation LP, was conducting flight JZA8909 from Greater Moncton Roméo Leblanc Intl (CYQM), NB to Montreal/Pierre Elliott Trudeau Intl (CYUL), QC with 4 crew members and 61 passengers on board.
During cruise flight at 16 000 feet, the aircraft experienced a loss of cabin pressure, accompanied by a loud popping sound heard from the back of the aircraft.
The flight crew donned their oxygen masks, initiated an
emergency descent to 10 000 feet, and declared a PAN PAN. The flight continued to destination without further incident.

The operator’s maintenance identified a leak from a faulty cargo door seal.

C-GLKY, a de Havilland DHC-8-300 aircraft operated by Perimeter Aviation LP, was conducting flight PAG663 from Winnipeg/James Armstrong Richardson Intl (CYWG), MB to Sandy Lake (CZSJ), ON with 3 crew members and 28 passengers on board. Shortly after takeoff, the flight crew received a lavatory smoke alarm, followed by the smell of smoke. The flight crew decided to declare an emergency, and returned to CYWG where the aircraft landed without further incident
with ARFF responding.
An inspection of the aircraft revealed a leaking compressor seal of the right engine (Pratt & Whitney Canada PW123), that introduced oil into the engine bleed air system. The aircraft was removed from service, and the engine was replaced.

C-GGGQ, a B200 Beech King Air aircraft operated by Miccar Aerial (dba Good Spirit Air Service), was conducting flight GT1128 from Prince Albert (Glass Field) (CYPA), SK to Yorkton Muni (CYQV), SK with only the 2 pilots on board. During the descent through 12 000 feet approximately 40 nm north of CYQV, the flight crew noticed fluctuations in the fuel flow and gas generator speed (ng) for the left engine (Pratt & Whitney Canada PT6A-42). As the flight continued in the descent, the left engine parameters returned to normal, then followed by a dramatic engine rollback. The flight crew feathered the engine, noticed an increase in ITT, and performed a precautionary engine shutdown. The aircraft landed without further incident in CYQV with emergency services
responding.

The operator’s maintenance replaced the fuel control unit.

The flight crew shut the engine (IAE V2500) down in accordance with QRH procedures, declared an emergency, and returned to CYYZ. The aircraft landed back on Runway 33R without further incident; there were no
reported injuries.
The operator’s maintenance replaced the Fuel Metering Unit and the Electronic Engine Control.

The aircraft was then returned to service.

C-FUOW, a privately-registered Cessna 340A aircraft, was conducting a flight from Vernon (CYVK), BC to Ponoka Industrial (Labrie Field) (CEH3), AB with 1 pilot and 2 passengers on board. Passing through 16 000 feet after the departure from CYVK, the right engine (Teledyne Continental TSIO-520-NB) experienced an uncommanded shutdown. The pilot feathered the propeller, declared a MAYDAY, and diverted to Kelowna (CYLW), BC where the aircraft landed without further event.

Maintenance personnel performed a ground run of the right engine, however were not able to determine the cause of the shutdown. Further investigation is ongoing.

C-FYMK, a Cessna 208B aircraft operated by Superior Airways, was conducting a flight from Red Lake (CYRL), ON to Pikangikum (CYPM), ON with the pilot and one passenger on board. During the initial climb at approximately 400 feet AGL, the pilot received a traffic alert, and initiated a best rate of climb. The aircraft then climbed out, and missed a helicopter by approximately 300 feet. It was reported that the traffic was C-GBOU, a privately operated Robinson R44 II helicopter.

The pilot of C-GBOU had reported its position 8 miles to the north east, during the initial takeoff roll of C-FYMK.

C-GOGT, a Beech 200 King Air aircraft operated by Missinippi Airways, was conducting flight MA03 from Thompson (CYTH), MB to Norway House (CYNE), MB with 2 crew members and 1 passenger on board. While climbing through 11 500 feet after the departure from CYTH, the left engine (Pratt & Whitney Canada PT6A-41) chip detector light illuminated.
The flight crew elected to perform a precautionary shutdown of the engine, declared an emergency, and returned to CYTH where the aircraft landed without further incident.

C-GOPP, a float equipped de Havilland DHC-3T aircraft operated by Harbour Air, was conducting sightseeing flight HES305 from Vancouver Harbour (CYHC), BC with 1 crew member and 9
passengers on board. During cruise flight, the pilot was unable to reduce the engine power setting while moving the power lever. The pilot entered an orbit over CYHC, and consulted with the operator’s maintenance. Subsequently, an emergency was declared, the engine (Pratt & Whitney Canada PT6A-34) was shut down, and the pilot performed a successful power-off water landing. The aircraft was then towed to the Vancouver Harbour dock. There were no injuries.

C-GLQQ, a Bombardier DHC-8-400 aircraft operated by Porter Airlines, was conducting flight
POE122 from Newark/Liberty Intl (KEWR), NJ to Toronto/Billy Bishop Toronto City (CYTZ), ON with 4 crew members and 27 passengers on board. As power was reduced once the aircraft reached its initial cleared altitude of 14 000 feet after the departure from KEWR, the flight crew noticed an unusual noise coming from the engines. Simultaneously, a POWERPLANT message was received, which prompted the flight crew to execute the QRH. In the absence of abnormal engine indications, the flight crew continued to monitor the situation, and contacted the operator’s maintenance via ACARS. Following a step climb to FL180, the number 2 Propeller Electronic Control (PEC) caution light illuminated, and the number 2 propeller RPM rose to 1060. The flight crew executed the QRH one more time, shut the number 2 engine (Pratt & Whitney Canada PW150A) down, declared an emergency, and elected to divert the aircraft to WilkesBarre/Scranton Intl (KAVP), PA where it landed without further incident with ARFF standing by. Following an inspection, the aircraft taxied to the terminal building.
Maintenance personnel determined that the number 2 Beta Feedback Transducer (BFT) failed, causing the propeller to initially go into an underspeed condition, followed by an overspeed condition. It was held at higher than normal propeller speeds (1060) by the Over Speed Governor (OSG) until the flight crew shut the engine down. The incident has been entered into the operator’s Safety Management System for further investigation.
