At 45 NM northwest of Chibougamau airport (CYMT), QC, and at FL250, the aircraft experienced rapid cabin depressurization. The crew conducted an emergency descent to 10 000 ft and cancelled the emergency once stabilized. They then asked to change their destination to La Grande Rivière Airport (CYGL), QC, where the aircraft landed without difficulty. No one was injured. July 23, 2015 Update: According to the maintenance personnel, the cause of the loss of pressurization was an emergency exit door seal that froze.

Incident at ST-JEAN QC (CYJN) (Communication navigation surveillance/air traffic system)

A privately owned Ward Star 125 was on a VFR flight from St-Jean (CYJN) to an unknown destination. At 0005Z, the aircraft was seen taxiing on Taxiway CHARLIE and taking off from Runway 29 without communicating with the tower. After takeoff, the aircraft headed north and the tower controller informed the Montréal terminal control unit (TCU) of the situation and the possibility that the aircraft may enter Class C airspace even though it did not seem to have a radio or transponder. The TCU continued to follow the aircraft on the primary radar and saw it cross St-Hubert (CYHU) controlled airspace, northbound, at an altitude estimated by the control tower to be approximately 1 600 ft. The TCU manager informed the sector?s Regional Operations Control Centre (ROCC) so that the flight could continue to be followed. The target eventually disappeared from the primary radar when it was approximately 10 NM north of the Mirabel (YMX) VHF omnidirectional range (VOR). There was no impact on ATC operations.

Incident at Vancouver ACC (ATM - other, ATM - NAVAIDS/radar)

At 0157z, AT&T had a T1 trunk failure somewhere between Vancouver city and Vancouver International airport (CYVR), causing the loss of the following services: Wallensteen Radar - all three lines (2 radar and the maint. line) 133.5 (Airports) 134.55 (East) 134.2 (Airports) 413 circuit 512 circuit 581 circuit 582 circuit North Bay ROCC Hotline and Landline Impact on ACC and users was minimal, due to time of day and low traffic volume. Sectors with frequency loss were able to utilize other frequencies with similar coverage area and circuit loss was minimized with outside line and/or hotline communication. Loss of radar was handled with procedural separation with no significant restrictions on the users. Eastside and Airports complexes were most affected with radar frequency and landline losses. The West Complex, the Terminals and ATOS also affected by Circuit losses. Outside facilities where circuits terminate were also affected. Full services were restored at 0714z.
