Incident at 10 nm southeast of Killaloe (YXI) VOR

C-GRPM, an FA20, North Bay (CYYB) to Ottawa (CYOW), shut down left engine 10nm southeast of Killaloe (YXI) VOR and declared an emergency requesting priority. No impact or delays incurred and aircraft landed safely at 1753z.
From the TSB Notification - A02O0040: C-GRPM, a Falcon 200 aircraft, was climbing through 15000 feet, en route to Ottawa MCIA, when an odour was detected in the cabin. The aircraft levelled off at 17000 feet and the odour became visible smoke in the cabin. The flight crew switched both bleed air switches off and the smoke disappeared. The crew determined that the problem was with the left engine (Honeywell ATF-3-6A-4C). A short time later the left engine oil pressure began to fluctuate and the oil temperature increased. The flight crew reduced left engine power to idle; however, the oil pressure continued to fluctuate and dropped below minimums. The engine was shut down and an emergency was declared. The aircraft continued to Ottawa and landed without further incident. Maintenance determined that a carbon seal failed in the engine resulting in the loss of engine oil.

Another aircraft: GIPV, a Geffair Navajo PA31 that had just departed Mirabel VFR for Dorval (CYUL). KNX7056, a Knighthawk Air Express FA20 coming IFR from Ottawa (CYOW), was on visual left-hand approach for Rwy 06 at Mirabel (CYMX) and in contact with the control tower. It was observed in an outbound climbing right turn. The control centre controller asked the tower to return the pilot to his frequency for an explanation. The pilot explained that he took evasive action away from traffic that he thought was in conflict with his aircraft. He also reported that he had to take this action because he did not receive adequate information from the control tower. The ACC returned the pilot to the Mirabel tower frequency. The radar printouts show that the traffic in question, a PA31 at 2000 ft south of the southbound approach, was never in conflict. The minimum distance between the two aircraft was never less than 3 radar miles laterally and 600 ft vertically. The required minimum separation is 1 radar mile or 500 ft. Autre aéronef: GIPV, Navajo PA31 de Geffair qui venait de partir de Mirabel à vue (VFR) à destination de Dorval (CYUL). KNX7056, FA20 de Knighthawk Air Express en provenance aux instruments (IFR) d'Ottawa (CYOW), était en approche visuelle par la gauche pour la piste 06 à Mirabel (CYMX) et en contact avec la tour de contr,le. Il a été observé dans un virage à droite en éloignement et en montée. Le contr,leur du centre de contr,le a demandé à la tour de retourner le pilote sur sa fréquence pour une explication. Le pilote a expliqué qu'il a pris une action évasive pour s'éloigner d'un trafic qu'il croyait être en conflit avec son appareil. Il a également signalé qu'il avait dû prendre cette action n'ayant pas reçu des informations adéquates de la part de la tour de contr,le. Le CCR a retourné le pilote à la fréquence de la tour de Mirabel. Les imprimés radar indiquent que le trafic en cause, un PA31 à 2000 pieds au sud de l'approche en direction sud, n'a jamais été en conflit. La distance minimale entre les deux aéronefs n'a jamais été de moins de 3 NM radar latéralement et de 600 pieds verticalement. L'espacement minimal requis est de 1 mille radar ou 500 pieds.

Incident at MONTRÉAL / PIERRE ELLIOTT TRUDEAU INTL QC (CYUL) (Conflict - loss of separation, ATS operating irregularity)

Two aircraft: N801SC (FA20), IFR from Binghamton, NY, to Dorval (CYUL), and ARN257 (B190), IFR from Bagotville (CYBG) to CYUL. N801SC and ARN257 behind it were both on radar vectors for Rwy 24 at CYUL. When 14 NM east of Dorval (CYUL), N801SC had to be vectored across the alignment to provide additional separation for a Medevac preceding it. Following this manoeuvre, the controller was late in advising ARN257 to turn in order to stay clear of N801SC; the two aircraft were 2.3 NM apart at the same altitude. There was no complaint from the pilots. Neither aircraft received a TCAS advisory. Deux aéronefs: N801SC (FA20), IFR, en provenance de Binghamton, (NY) vers Dorval (CYUL) et ARN257 (B190), IFR en provenance de Bagotville (CYBG) vers CYUL. N801SC suivi de ARN257, étaient tous deux sur vecteurs radar pour les pistes 24 à CYUL. À 14nm à l'est de Dorval (CYUL), N801SC a dû être guidé à travers l'alignement afin de fournir un espacement additionnel à un Medevac qui le précédait. Suite à cette manoeuvre, le contr,leur a tardivement avisé ARN257d'effectuer un virage pour l'éloigner de N801SC, mais les deux aéronefs se sont retrouvés à 2.3nm l'un de l'autre, à la même altitude. Il n'y a eu aucune plainte des pilotes. Les deux appareils n'ont reçu aucun avis TCAS.

15 NM in final for rwy 11 at Mirabel Airport (CYMX) from Ottawa (CYOW), KNX7056 (FA20) suffered a communication failure. Mirabel Tower transmitted it clearance to touch down using light guns. At 2 NM in final, the pilot was receiving the tower. The aircraft touched down without incident. No impact on operations. UPDATE: The TSB investigation revealed that the crew of the Falcon 20 suffered a partial loss of VHF reception and selected the communication failure code on the transponder. Inspection revealed that water or moisture probably got into the co-pilots audio unit when it was changed in the rain. Alors qu'il était à 15nm en finale pour la piste 11 à l'aéroport de Mirabel (CYMX) en provenance d'Ottawa (CYOW), KNX7056 (FA20) a subi une panne de communication. La tour de Mirabel lui a transmis l'autorisation de se poser avec l'aide de signaux optiques (light gun). À 2nm en finale, le pilote recevait la tour. L'appareil s'est posé sans encombre. Pas d'impact à l'exploitation. MISE À JOUR: L'enquête du BST a révélé que l'équipage du Falcon 20 a subi une perte partielle de réception du VHFet a alors sélectionné le code de panne de communication sur le transpondeur. Après inspection, une fuite d'eau ou de moisissure se serait probablement introduite à l'intérieur de la boîte audio du copilote, car lors du chargement, il y avait des averses de pluie.

At 0242Z, as he was in approach 5 NM northeast of Dorval Airport, the pilot of KNX1701 (FA20) declared an emergency because of loss of an engine. The aircraft was given priority and vectored for final. AES was advised. The aircraft touched down at CYUL without incident at 0247Z. UPDATE: The TSB investigation revealed that poor management of the fuel balancing system caused engine 1 to stop for lack of fuel. The crew therefore declared an emergency and were assigned priority. The crew were able to restart the engine as the aircraft was in final for the runway. The landing proceeded without incident. À 0242Z, alors qu'il était sur l'approche à 5nm au nord-est de l'aéroport de Dorval, le pilote de KNX1701 (FA20) a déclaré une urgence, suite à la perte d'un moteur. Une priorité lui a été donnée et l'appareil fut guidé pour la finale. Les services d'urgence aéroportaires (SUA) ont été avisés. L'aéronef s'est posé à CYUL sans encombre à 0247Z. MISE À JOUR: L'enquête du BST a révélé qu'une mauvaise gestion du système de balancement du carburant a entraîné l'arrêt du moteur #1, dû à un manque d'alimentation de carburant. L'équipage a alors déclaré une urgence et une priorité leur a été accordée. L'équipage a été en mesure de repartir le moteur, alors que l'avion était en finale pour la piste. L'atterrissage s'est déroulé sans problème.
