Incident at FORT MCMURRAY AB (CYMM)

A Landcare Aviation Inc. Cessna 172S (N370JA) from Fort McMurray, AB (CYMM) to Calgary/Springbank, AB (CYBW) departed on the CYMM 2 standard instrument departure (SID). The controller turned N370JA southbound before issuing a departure clearance for a Landcare Aviation Inc. Cessna 172P (N53134) from Fort McMurray, AB (CYMM) to Calgary/Springbank, AB (CYBW). On departure, N53134 broke the CYMM 2 SID and turned southbound. Separation was decreased to 3.4NM, where 5NM is required.
Update: TSB Report #A20W0057: Landcare Aviation Inc. Cessna 172S (N370JA) and Cessna 172P (N53134) were departing Fort McMurray (CYMM), AB, on a flight to Rome (KRME), New York, USA. The two aircraft had filed instrument flight rules (IFR) flight plans and were both departing on the Fort Mac 2 Standard Instrument Departure (SID). N370JA departed first and climbed straight ahead, as required, expecting to climb to seven thousand feet as directed in the SID. At 2500 feet above sea level (ASL), the departure controller cleared N370JA for a right hand turn and released the aircraft from the SID before issuing a departure clearance for N53134. On departure, N53134 did not follow the Fort Mac 2 SID departure, turning Southbound early and without authorization. Separation decreased to 3.4NM, where 5NM was required.

Incident at SAULT STE. MARIE ON (CYAM) (Ground handling services)

TSB #A16O0151: C-GGBF, a de Havilland DHC-8-402 aircraft operated by Jazz Aviation LP, was conducting flight JZA8330 from Sault Ste. Marie, ON (CYAM) to Toronto/Lester B. Pearson Intl, ON (CYYZ). Prior to departure, during the turn around on the ground in CYAM, ground handling personnel did not inspect all baggage and cargo compartments as per Standard Operating Procedures (SOP) and therefore, 858 lbs of baggage was left onboard in hold number 3, and was unaccounted for. The aircraft departed for CYYZ and flew uneventfully although the MAC was 5.39% forward of the forward limit. As a new cabin crew was taking over on the following flight in CYYZ, they discovered the bags in hold number 3. The flight crew advised that they did not notice anything unusual about the behavior of the aircraft during the flight. The operator performed a review of the SOPs with the ramp personnel in CYAM and will be sending out a complete review to all employees.

The Heli-Inter Inc. Robinson R-44 Beta II helicopter (C-GFHC) was on a local VFR flight from Ottawa (Gatineau) Airport (CYND). NAV CANADA staff at Ottawa Tower reported that, on completion of a city tour, the helicopter was observed at a reported altitude of 1,300 feet in CYR538 (Rideau Hall). The pilot was advised of the correct altitude with regard to CYR538 prior to returning to Ottawa (Gatineau) Airport (CYND). Ops. impact -- none.
UPDATE Follow-up information received from Commercial & Business Aviation (Québec Région) [2011/09/14]: A Civil Aviation Safety Inspector (CASI) contacted the operator about this occurrence. The CASI was advised that according to the pilot, the route flown was the normal one for the air tours of the city of Ottawa. That afternoon, the cloud base was a bit low and the pilot was given permission to conduct the tour at an altitude of 1,200 feet. For the pilot, the aircraft passed over the MacDonald-Cartier Bridge near Parliament Hill. In conclusion, the pilot was very aware of the controlled/restricted airspace which the aircraft passed close to. The operator has subsequently changed the air tour flight path (of downtown Ottawa) by several miles to avoid future problems of this nature. __________ Selon le pilote, c?est le circuit habituel pour les tours de ville d?Ottawa. Cet après-midi là, le plafond était un peu bas et la tour lui a autorisé le vol à 1200 pieds. Pour lui, il a passé au-dessus du Pont Mac Donald Cartier à l?écart du parlement. En conclusion, il semble qu?il est passé trop proche de la zone contrôlée en connaissant très bien sa présence. La compagnie va changer de quelques miles la trajectoire du tour de ville pour éviter toute confusion à ce sujet.
