MAX190 received and read back the authorization while taking off. No impact on operations.
Update: According to information from the Commercial and Business Aviation Division, the error was due to the two pilots? poor understanding of the authorization received. The pilots interpreted the controller?s response as a VFR takeoff validation.

Incident at Active Pass, BC NDB (AP)

Approximately 5-7 minutes after a privately registered Cessna 172 from Boundary Bay, BC (CZBB) to Courtney Airpark, BC (CAH3) received routing instructions from air traffic control (ATC), the aircraft was unreachable and subsequently squawked 7600.

Check was made with local aircraft within the zone. Two pilots indicated ELT signal strength decreases and ends as they descend onto CYBL. Information was passed to the RCC.

March 3, 2010

Incident at Bagotville Area (Moncton ACC) (TCAS alert)

At approximately 15:28Z, ACA868, Boeing 767-300, enroute from Toronto (CYYZ) to London (EGLL) at 37,000 ft., reported that they had an aircraft on TCAS at the same flight level off their left side. After reviewing the radar tapes it appears that an F18 working in the Bagotville (CYBG) area left the airspace and proceeded toward ACA868. The aircraft in question was squawking code 0103 then squawked 1200 when leaving the Bagotville airspace proceeding directly toward the Air Canada flight. The target was lost on Radar shortly thereafter. The pilot and Bagotville MTCU were contacted and informed us the F18 (Alout55) proceeded from the military airspace doing a high altitude climb, 20,000 ft. per minute, and leveled off at 9,000 ft. then proceeded to Baie-Comeau (CYBC) for a VFR approach before returning. The TCAS alert may have been caused by the high rate of climb. The National Operations Centre (NOC) and NORAD/Sidecar were advised. Nil TSB.

UPDATE / Add Info from TSB: A09P0233 - The Air Norterra Boeing 737-200 aircraft, operating as MPE9601, took off from Comox for Victoria and was cleared to 9,000 feet. Before the aircraft was handed over to Victoria Terminal, Comox Military Terminal cleared MPE9601 to maintain 13,000 feet, but the revised altitude was not passed to Victoria Terminal. An operating irregularity occurred when the aircraft entered Victoria terminal's airspace at 13,000 feet and safety was not assured.

June 12, 2009

Incident at 5230N/10600W

NATO 11, a military E3 Sentry was en route from CFB Cold Lake to CFB Bagotville when the aircraft entered Class A airspace without an ATC clearance. The crew had been instructed by Cold Lake MTCU to obtain an IFR clearance via them at mission completion.

March 9, 2009

Incident at CONKLIN (LEISMER) AB (CET2)

NCB 886, a Beech King Air C90 operated by North Cariboo Flying Service, was en route IFR from Conklin to Calgary when Edmonton Centre observed the aircraft on radar at 10,600 feet ASL within CYR 221.

March 22, 2007

Incident at VICTORIA INTL BC (CYYJ)

At 1441Z an American-registered corporate Cessna C501, on a IFR flight from Victoria to Anchorage, AK, departed on Victoria International Runway 09 on a Victoria Three DEP, which has instructions to climb to 3000' on runway heading and contact Victoria Terminal after passing 1,000'. The aircraft climbed to 3,000' on runway heading without contacting the Terminal. As the aircraft was heading for Whitby MTCU airspace, the controller coordinated with Whitby for a point out. At 1446Z and 17 miles from Victoria Airport, the controller was able to contact the pilot of the aircraft on frequency 121.5. The pilot was instructed to turn right two zero zero degrees, maintain 4,000' and to expedite climb for terrain. The pilot acknowledged, and the aircraft was observed climbing to 4,800' before finally leveling out at 4,000'. The aircraft continued on without further incident.

November 29, 2005

Incident at Vicinity of Confederation Bridge

C-FYPU, Piper PA28, enroute Summerside (CYSU) to Waterville (CCW3) VFR, lost communication and transponder return at 1900Z. Prime target observed consistent with track of C-FYPU. TGO998, BE90, St. Anthony (CYAY) to Moncton (CYQM), was vectored to the vicinity of the prime target. TGO998 cancelled IFR and descended when the PA28 was in sight. The PA28 did not seem to be in any difficulty. Greenwood MTCU was advised and contacted Waterville airport. C-FYPU landed at Waterville at 2010Z. Aircraft had a complete electrical failure. TSB Case Closed
TSB Update: A05A0153: While transiting VFR from Summerside to Waterville, the pilot of C-FYPU, a PA-28-140, was advised that Moncton ACC was not receiving his transponder. He then noticed that his radio transmissions were not being heard. Shortly afterwards the aircraft's electrical system failed. ATC diverted a Transport Canada Beech 90 to investigate. As C-FYPU was not in distress, it continued en route. Moncton ACC advised Greenwood and Waterville of the inbound aircraft. C-FYPU made an uneventful NORDO landing at Waterville. The electrical failure was caused by a broken field wire on the alternator.
Maintenance & Manufacturing Update: The pilot advised that maintenance staff found that the field wire on the alternator had separated allowing the battery to discharge and cause a complete electrical failure.

September 1, 2004

Incident at CAMPBELL RIVER BC (CYBL) (Alleged Canadian Aviation Regulations (CARs) infraction)

Central Mountain Air flight GLR342 a Beech 190 called FSS at Campbell River on MF. The assisting specialist responded and asked the aircraft to standby. The specialist was copying clearance from Comox MTCU on phone line for the Beech 190 who was taxiing for a runway 11 departure. C-GKNH a Parallel Aviation Cessna 172M then broadcasted ""to position and rolling"" and entered runway 29. The specialist finished copying the clearance, but did not read it back as required in order to advise the Cessna 172M that he needed an advisory before departure and before entering the runway. The Cessna 172M complied by vacating runway 29 and taxiing for runway 11. When the specialist advised Comox ATC of the Beech 190 departure time, he was told that he had not read back the clearance as required.

March 17, 2004

Incident at MOOSE JAW / AIR VICE MARSHAL C.M. McEWEN SK (CYMJ)

C-FGZQ, a Cessna 340, departed Estevan SK and the pilot requested an IFR clearance to Swift Current. The flight-planned route would have taken the a/c through the CFB Moose Jaw (YMJ) Military Terminal Ccontrol Unit (MTCU) and so the Winnipeg ACC Controller issued a clearance with an ammended route circumventing the MTCU. The pilot, after numerous attempts, had still not read back the correct routing portion when communications were lost due to poor frequency coverage. The pilot did deviate from his assigned route and transited the Moose Jaw Military Terminial Control Area. The flight's activity was co-ordinated with Moose Jaw TCU prior to penetration. The pilot later called ACC to report that his a/c was experiencing radio, GPS and autopilot problems.

February 5, 2002

Incident at GREENWOOD NS (CYZX) (Conflict - potential, Conflict - loss of separation, ATS operating irregularity)

Operating irregularity. At 2248Z the Moncton ACC (Digby Sector Controller) issued a clearance for CFC1624 (a P3) to LICZ via Greenwood direct to YQY flight planned route at 9000 ft. At 2307 the Moncton ACC issued a clearance via the Greenwood MTCU for C-GJDI (a DHC6) from Waterville airport (approximately 10 nm east of Greenwood) to Saint John airport, to maintain 3000 ft. The 3000 ft altitude was used to ensure sufficient separation with CFC1624 crossing track in airspace controlled by Moncton. Greenwood reported the departure of C-GJDI at 2312Z, confirming the coordinated altitude of 3000 ft. At 2316 the Greenwood controller advised Moncton that C-GJDI was cleared to 4000 ft in order to meet direction of flight rules. This now put C-GJDI within Moncton controlled airspace with no planned separation with CFC1624. TSB Evaluating
