A few minutes later, C-GZKD called back to advise they had their ELT re-cycled, and now the ELT was gone. No impact on operations.

The Fort St. John, BC (CYXJ) flight service station (FSS) observed a target on the NAV CANADA Auxiliary Radar Display System (NARDS) entering the CYXJ control zone from the southeast. No response on the mandatory frequency. The FSS got ahold of the aircraft on 126.7 MHz via hand-held radio (NICAN) and identified the target as a Yellowhead Helicopters Ltd.

TSB Report #A22C0040: C-FDOD, a Bell 412 helicopter operated by Wisk-Air Ltd., was returning 4 drums containing Jet A-1 (UN 1863) fuel from a cache near Prospect Lake, ON, to the Ontario Ministry of Natural Resources (OMNR) fire base at Red Lake, ON. The pilot supervised the loading and the sling gear had been inspected and found serviceable prior to departure. After takeoff, the pilot de-activated the electrical release on the cyclic control. Approximately 8 minutes later, the load of 4 fuel drums fell to the ground. All of the drums were damaged and 3 released their contents. The remaining drum still held fuel. The fuel drums were retrieved by OMNR personnel on June 12 and remediation of the site was conducted. Details of the event were reported to CANUTEC. The operator reported that abrasion to the retaining strap connecting the load to the belly hook indicated that it had worked itself around and under the hook keeper. The hook and release mechanism were inspected and found serviceable. The emergency foot release had not been used. The operators aircrews that used the same helicopter type and hook system were notified.

Unknown operational impact.

At Sioux Lookout, ON (CYXL), while the receiver (RX) on 121.5 MHz was unserviceable (U/S), the hand-held radio (NICAN) had been used to monitor the frequency. It was discovered to be off at 0050Z, thus 121.5 MHz was unmonitored. No known impact to operations.

Upon exiting Pad 6, an Air Transat Airbus A321-271NX (TSC186) from Toronto/Lester B.

Aviation Incident Report: A Kenn Borek Air de Havilland DHC-6-300 (C-FDHB) from Liberia, Costa Rica (MRLB) to Houston, TX (KHOU) landed on Runway 4 and taxied to Taxiway R. After the aircraft was clear of the runway and switching to ground control, the aircrafts brakes and left tire caught on fire. There was a small amount of smoke coming from the aircraft, but no visible flames. The fire station was alerted and rolled the trucks, however, before the trucks arrived, the pilot put out the fire using an on-board fire extinguisher. The aircraft was towed to the fixed-base operator (FBO). No damage to airport property. No injuries. Extent of damage unknown.
UPDATE: TSB Report #A22F0022: C-FDHB, a Kenn Borek Air Viking DHC-6-200 was conducting a flight from Liberia/Daniel Oduber Quirós Intl, Costa Rica (MRLB) to Houston/William P. Hobby, TX (KHOU). After landing in KHOU, the pilot applied brakes to exit via the taxiway and felt that the airplane grabbed a bit more then usual on the left-hand side. After exiting the runway, the flight engineer on board called Fire on the left-hand side of the airplane. The pilot stopped the airplane and shut down the engines. The flight engineer jumped out and extinguished the fire on the left-hand main landing gear with a hand held onboard fire extinguisher. After inspection, it was discovered that the left-hand brake caliper had broken free from its mount and rotated forward, severing the hydraulic lines.

A Maxium Mechanical Ltd. Cessna T210K (C-GCDJ) from Kelowna, BC (CYLW) to Calgary/Springbank, AB (CYBW) declared a "PAN PAN" on 121.5 MHz over Ghost Lake due to low cloud. The tower tried to reach the aircraft on the National Voice Communication System (NVCS) and the hand-held radio (NICAN), but the aircraft reported "readability 1-2". Air Canada relayed messages between the tower and the aircraft in distress. With assistance, the aircraft managed to locate the Trans Canada Highway and followed it, low-level, to the field for landing. No impact to operations.

A Conair Group Inc. Rockwell 690A (FGD135) from Whitehorse/Erik Nielsen, YT (CYXY) to Whitehorse/Erik Nielsen, YT (CYXY) reported a punctured left main tire upon landing on Runway 14R.

At 1727Z, the tower cleared a McMurray Aviation Beech 1900C (C-GLPJ) from Fort Chipewyan, AB (CYPY) to Fort McMurray, AB (CYMM) to land on Runway 08, which C-GLPJ read back. At 1728Z, technologists requested that the Unit Operations Specialist (UOS) reset the tower position National Voice Communication System (NVCS), which resulted in all NVCS at all positions to fail. At 1729Z, C-GLPJ asked the tower if they were cleared to land, but received no response due to the equipment failure, and so the aircraft conducted a missed approach. The tower turned on the hand-held radio (NICAN) and issued missed approach instructions. C-GLPJ landed at 1737Z. No other impact to operations.

A power loss occurred at 1158Z at Rankin Inlet, NU (CYRT). The Duty Specialist advised the Technology Operations Coordinator (TOC) that the very high frequency (VHF) transmitters were unserviceable (U/S). The TOC advised the specialist that the generator at the VHF site failed to auto-start. The Team Supervisor (TS) was sent to inspect/restart. The Duty Specialist used the hand-held radio (NICAN) for vehicle and aircraft movements. Human Weather Observation System (HWOS) sensors were also U/S and the 1200Z weather (WX) report was sent late due to other duties being performed. No impact to operations. The generator needed to be manually started and the TOC advised not switching to auto start mode until commercial power was restored. TS to return to transmitter site at that time.

The Thompson (YTH) flight service station (FSS) reported that a Perimeter Aviation flight (PAG773) requested to have their VFR flight plan closed.

WEN3419 initially requested a return to CYQM and then requested a diversion to Halifax/Stanfield, NS (CYHZ) due to the availability of maintenance. The pilot declared "PAN PAN" at 1837Z. The Aircraft Rescue and Fire Fighting (ARFF) unit was requested. No additional assistance required. Aircraft held until 1955Z to burn fuel and landed safely at 1959Z.

A commercial power bump caused frequency 119.00 MHz to fail. The controller switched to the hand-held radio (NICAN) and communicated with aircraft. The Technology Operations Coordinator (TOC) was advised.

At approximately 1525Z, an Air Inuit de Havilland DHC-8-314 (C-GXAI/AIE859) from Quebec/Jean Lesage, QC (CYQB) to Wabush, NL (CYWK) advised they were breaking off the approach and proceeding to hold at the fix ODGAL at 5000ft to work through a checklist. AIE859 held at ODGAL until 1602Z, at which time they advised they were diverting to Schefferville, QC (CYKL) but did not provide a reason.
