Incident at MONTRÉAL / PIERRE ELLIOTT TRUDEAU INTL QC (CYUL) (ATS operating irregularity)

At departure, there was a loss of lateral separation between a WestJet Encore Bombardier DHC-8-402 (C-GWJK/WEN3535) from Montreal/Trudeau, QC (CYUL) to Toronto/Pearson, ON (CYYZ) and an Air Transat Airbus A321-271NX (C-GOIE/TSC546), from Montreal/Trudeau, QC (CYUL) to Bordeaux–Merignac, France (LFBD) when the tower forgot to instruct WEN3535 to turn before its takeoff.
TSB Update #A19Q0099: C-GWJK, a WestJet Encore de Havilland DHC-8-400, was on flight WEN3535 from Montreal/Pierre Elliott Trudeau, QC (CYUL) to Toronto/Lester B. Pearson Intl, ON (CYYZ). C-GOIE, an Air Transat Airbus 321-200, was on flight TSC546 from CYUL, to Bordeaux/Mérignac, France (LFBD). Simultaneously, the 2 aircraft positioned themselves for their respective takeoffs: WEN3535 on Runway 24R, and TSC546 on Runway 24L. The information available to the controller responsible for the departures indicated that WEN3535 had to make a 30° right turn during the initial climb; however, this information was not transmitted to the crew by the controller in service. After the 2 aircraft had each received their respective departures, there was a change in controller. When the replacement controller noticed that WEN3535 was not initiating the right turn as specified in the data system, he instructed the crew to turn right to obtain the required separation. The takeoff paths were parallel, and the separation was consequently reduced to 1.3 NM horizontally and 900 ft vertically before WEN3535 initiated its turn.

January 3, 2019

Incident at 26NM HALIFAX / STANFIELD INTL NS (CYHZ)

A WestJet Encore Ltd. Bombardier DHC-8-402 (C-GWJK/WEN3428) from Halifax/Stanfield International, NS (CYHZ) to St. Johns International, NL (CYYT) returned to CYHZ due to a gear issue. The aircraft held to burn fuel. At 1255Z, the aircraft declared "PAN PAN" and requested Aircraft Rescue and Fire Fighting (ARFF) services on landing. After a tower fly-by for a gear check, the aircraft landed safely at 1343Z. The Joint Rescue Coordination Centre (JRCC) Halifax was advised.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. On the evening before the event, a Service Bulletin was accomplished on the nose landing gear of tail 443 (C-GWJK). The modification involved replacement of the drag strut lower lock link. This task required the removal and reinstallation of the Nose Landing Gear (NLG) lock proximity sensor brackets. Following the CADOR event, Maintenance found that the NLG lock sensors had been rigged to the nominal gap (~0.050”). However, the inductance readings in the Proximity Sensing Electronic Unit (PSEU) were too far (8.029mH and 8.010mH, rigging range is 8.196mH-8.438mH). No movement was found on the sensor brackets. The sensor rigging was adjusted to within the appropriate range, gear swings were carried out, and the aircraft was returned to service.
TSB Report #A19A0002: C-GWJK, a Bombardier DHC-8-400 aircraft operated by WestJet Encore, was conducting flight WEN3428 from Halifax/Stanfield Intl (CYHZ), NS to St Johns Intl (CYYT), NL. Upon selection of landing gear up shortly after the takeoff, the nose landing gear failed to retract. The flight crew declared an emergency, and performed a low approach for a visual inspection by the control tower. Following a holding of approximately 1 hour to burn fuel, the aircraft landed without incident at CYHZ. The flight crew was able to taxi the aircraft to the gate under its own power. The operator’s maintenance determined that the rigging for the NGLK1 and NGLK2 sensors needed to be reset. A gear swing was completed, and the aircraft released to service.

Update from the TSB: The Boeing 737-200 (C-GWJK) initial take-off on runway 15 was rejected due to an incorrect reading on the #2 engine (JT8D-17A) EPR gauge. The aircraft was taxied to a run-up area where the problem appeared to correct itself. On the second take-off attempt, the incorrect EPR reading returned. The aircraft was taxied back to the gate where maintenance cleaned an electrical connector for the EPR controller. The aircraft successfully departed Prince George airport on the third attempt.

February 9, 2003

Incident at Kelowna (TCAS alert, Conflict - potential, Conflict - loss of separation, Alleged Canadian Aviation Regulations (CARs) infraction)

Update from the TSB: A loss of separation occurred between a Boeing 737-269 [C-GWJK] operated by Westjet Airlines as Flight 31 and a Beech 100 [C-GHOC] operated by Ken Borek Air. The 737 was inbound to Kelowna, just North of Vernon at 11,000 feet ASL when the pilot called the Center to cancel IFR and requested from the Tower to land straight-in on runway 15. Tower suggested to join left downwind for runway 33 and fly out over Lake Okanagan. The B100 on departure from runway 33 was instructed to follow the SID as they were tracking east of the localizer. Flight 31 continued toward the lake on a track that would take the aircraft across the localizer just North of the LW Beacon. The 737 pilot queried ATC if B100 would be turning East, ATC responded in the affirmative and asked the pilot to turn left and fly down the east side of the valley. ATC repeated the instruction to turn left and the pilot began a fairly abrupt left turn. Shortly thereafter, the 737 pilot received a TCAS resolution advisory (RA), to climb. He advised ATC they were following the RA and observed that the separation was about 1.5 miles lateral and 400 feet above the traffic. The 737 was able to climb clear of conflict and proceeded to land.
WJA31 southbound approximately 11 north of the airport, KBA100 approximately 11 north of the airport climbing northbound 1nm east of the localizer. Traffic passed, WJA31 told to make a left turn, WJA31 was not observed making the left turn. WJA31 reports TCAS RA at approximately 8000'. Kamloops sector advised no report from KBA100. Passed with 1nm and 800'.

July 20, 1997

Incident at Calgary, AB

WJA 50 was taxiing for departure on a regular scheduled flight to Regina and proceeding north on Taxiway C. The pilot reported that one of the a/c's engines had injested a plastic bag in the vicinity of Taxiway CA. The a/c taxied across Runway 16 to the holding bay to carry out some further checks, and then the pilot said he was ready for takeoff. As the a/c was rolling on Runway 16, a takeoff warning horn sounded, so the crew aborted the takeoff. The crew taxied the a/c back to position and attempted a second time to take off, but the same thing occurred, so the crew brought the a/c back to the terminal. Maintenance states that the problem could not be duplicated during subsequent checks, but it is suspected that the speed brake quadrant switch was out of sequence. It was also believed that the plastic bag injestion was not a factor in the takeoff aborts. The a/c has been returned to service. UPDATE As the crew advanced the power levers for takeoff, the takeoff warning horn sounded, so the crew retarded the levers and taxied off the runway. They checked the trim, flap settings and speed brakes and everything was in the normal takeoff configuration, but when power was increased for the second attempt to takeoff, the warning sounded again, so the crew took the a/c back to the terminal. Maintenance could not diagnose any problems and the a/c later departed without incident. It is suspected that the speedbrake quadrant switch may have malfunctioned or was out of sequence. The a/c had a crew of 5 and 95 passengers on board.
