Incident at LONDON ON (CYXU) (Conflict - potential, Communication navigation surveillance/air traffic system, Communication error, ATS operating irregularity)

Supplemental information from T.S.B. Initial Notification (#A05O0098): At 2136Z, the westbound American Eagle Canadair Regional Jet (flight #EGF192) aircraft reported to the Oakville Sector West High controller and received clearance to climb to FL350, which the pilot readback. At London (YXU), EGF192 passed under and to the left of an Air Canada Regional Jet (flight #ACA520) who was eastbound at FL350. The vertical spacing was 2,500 feet at the time that the aircraft passed each other (minimum vertical spacing required is 1,000 feet). At 2140Z, the controller handed off EGF192 at FL350. The Minneapolis (MSP) controller asked the Oakville controller to confirm FL340. The Oakville controller confirmed FL340 and then turned EGF192 right 30 degrees and instructed the aircraft to descend to FL340. This instruction was required to avoid opposite direction traffic, a Midwest Express Boeing 717 (flight #MEP5) aircraft who was level at FL350 eastbound on a reciprocal track. Although there was no loss of separation, EGF192 and MEP5 were 6 NM apart laterally when separation was assured. NAV CANADA is conducting an Operational Safety Investigation (OSI).
The A.M.R. American Eagle Airlines Inc. Canadair Regional Jet 700 aircraft (operating as EGF192) was on a scheduled IFR flight from Buffalo (Greater Buffalo) International Airport, NY (U.S.A.) (KBUF) to Chicago (O'Hare) International Airport, IL (U.S.A.) (KORD). The Midwest Airlines, Inc. (Oak Creek, WI) Boeing B-717 aircraft (operating as MEP5) was on a scheduled IFR flight from Milwaukee (General Mitchell) International Airport, WI (U.S.A.) to New York (La Guardia) International Airport, NY (U.S.A.) (KLGA). At 2136Z, the flight crew of EGF192 reported to the Oakville Sector West High Controller and received clearance to FL350. The flight crew read back the clearance. At London (CYXU), EGF192 passed under (and left of) ACA520, who was eastbound at FL350. There was 2,500 feet of vertical separation at the time the aircraft passed. At approximately 2140Z, the controller handed off EGF192 at FL350. The MSP Controller asked the Oakville Controller to confirm FL340. The controller confirmed FL340. The Oakville Controller instructed EGF192 to turn right 30 degrees and descend to FL340. This instruction was required to avoid opposite direction traffic, MEP5 (who was level at FL350 eastbound on a reciprical track). EGF192 and MEP5 were laterally 6 NM apart when separation was assured.

Incident at QUÉBEC / JEAN LESAGE INTL QC (CYQB) (TCAS alert)

Air Canada Boeing 737 ACA520 was advised it might receive a TCAS advisory because Institut aéronautique de la Capitale Cessna 152 C-GQQE was in the circuit at 1300 feet. As anticipated, ACA520 received a traffic advisory followed by a resolution advisory when it was 3 NM on final at 1300 feet. ACA520 had the Cessna visual and landed without further incident. ACA520, un Boeing 737 d'Air Canada, a été informé d'une possibilité d'avis du système de surveillance du trafic et d'évitement des collisions (TCAS) car C-GQQE, un Cessna 152 de l'institut aéronautique de la Capitale, était en circuit à 1300 pieds.

Incident at QUÉBEC / JEAN LESAGE INTL QC (CYQB) (TCAS alert)

Air Canada Boeing 737 ACA520 was 3 NM on final for rwy 06 at Quebec City (CYQB) when it received two TCAS resolution advisories. There were two traffics in the circuit, including Institut aéronautique de la Capitale Cessna 152 C-GQQE. Traffics were exchanged, and no further advisories were issued after C-GQQE landed. On the first advisory, ACA520 applied throttle to pull up, but the advisory was immediately cancelled, then reissued a few seconds later. The aircraft was advised of the problem C-GQQE was having, and it continued the approach and landed without further incident. ACA520, un Boeing 737 d'Air Canada, était 3 MN en finale pour la piste 06 à Québec (CYQB) lorsqu'il a reçu deux avis de résolution du système de surveillance du trafic et d'évitement des collisions (TCAS). Il y avait deux trafic en circuit dont C-GQQE, un Cessna 152 de l'Institut aéronautique de la Capitale. Les trafics ont été échangés et lorsque C-GQQE s'est posé, il n'y a plus eu d'avis TCAS. Au premier avertissement, ACA520 aurait remis les gaz pour effectuer une remontée mais l'avis s'est terminé immédiatement pour reprendre quelques secondes plus tard. L'appareil a été informé du problème de C-GQQE, il a continué son approche et a atterri sans autre incident.
