August 5, 2021


TSB Report #A21Q0066: A Parachutisme Adrénaline Inc. Cessna P206A (C-FMHQ) was on a parachute flight from the Trois-Rivières, QC (CYRQ) airport. On the landing roll, directional control of the aircraft was lost and the aircraft ended its course on the grassy part of the runway. The aircraft’s propeller was damaged; the pilot, the only occupant on board, was not injured.
Aviation Incident Report #17224: When landing on Runway 23 at Trois-Rivières, QC (CYRQ) after a parachute drop, a Parachutisme Adrénaline Cessna P206A (C-FMHQ) from Trois-Rivières, QC (CYRQ) to Trois-Rivières, QC (CYRQ) made a runway excursion into the grass south of Runway 23, at about the height of Taxiway A. The pilot reported that when the nose wheel touched down after the main landing gear in the centre of the runway, the aircraft began to veer slightly to the left. The pilot unsuccessfully attempted to correct it by throttling right. With increased movement to the left, additional right throttle pressure was applied until full deflection, again unsuccessfully. The pilot then applied the right brake to attempt to correct the aircrafts trajectory, which did not seem to respond to the rudder pressure. Now sliding to the left and seeing only trees and a fence in front, conducting a go-around was no longer an option for the pilot. At this point, both brakes were applied to slow the aircraft down as much as possible before exiting the runway. The aircraft ended its course with its nose in the grassy part. The engine continued operating and running normally. Since no damage was apparent, the pilot taxied on the ground without assistance up to Planet-Air Maintenance. The aircraft appeared to respond properly to the brake/rudder commands while taxiing on the ground following its exit from the runway. The aircraft was sent to an approved maintenance organization (OMA) that will inspect and try to determine if a mechanical failure might have been the cause. An inspection will take place following the event. On the flight operations side, since the exact reason for the incident was not known at the time of the report, a discussion was held regarding best flight practices.

UPDATE: TSB Report #A21Q0051: A privately registered Cessna 185 on floats that was tied to a private dock on Rivière des Prairies, approximately 4 NM north-west of Montréal/Pierre-Elliott-Trudeau, QC (CYUL), was getting ready to perform a local visual flight rules flight. While the aircraft taxied on water, the pilot followed the checklist in preparation for takeoff. The checklist did not indicate to check for removal of the control surface locking device and the aircraft was not equipped with an approved device. However, an unapproved device had been installed the previous day and had not been removed during preparation for takeoff. The aircraft began its takeoff on the water when the pilot noticed that the flight controls were blocked. The aircraft was able to rise above water but was not able to rise any further. The aircraft descended back down and nosed over forward just as the floats touched the water’s surface, and then flipped over. The pilot was held in the seat by a 4-point seatbelt and was wearing a PFD. The pilot was able to quickly evacuate the aircraft and was not injured. A boat came to rescue the pilot, who was brought to shore.

April 25, 2021


A Carson Air Ltd. Beech 1900D (C-FBTR/CRN511) from Kelowna, BC (CYLW) to Prince George, BC (CYXS) experienced an issue with its landing gear while on approach to CYXS. The pilot decided to return to CYLW. The aircraft landed at CYLW at 1759Z without issue, with the Aircraft Rescue and Fire Fighting (ARFF) unit on standby. The pilot did not declare an emergency.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. On approach into Prince George, BC (CYXS), the flight crew of CRN511 had no green "gear down" annunciation. Once the crew had established that the landing gear was down and locked, they chose to return to Kelowna, BC (CYLW), where maintenance could address the issue. Maintenance found that the landing gear green annunciators were unlatched and would only show green when pushed in and held. Once the annunciators were manually reset, they functioned normally. The flight crew had inadvertently unlatched the annunciators during flight, which caused the indication to be lost. The flight crew have been briefed on annunciator operation.

April 8, 2021


A privately registered Mooney M20K from Langley, BC (CYNJ) to Langley, BC (CYNJ) reported a faint emergency locator transmitter (ELT) signal on the ground as it taxied in and shut down.

February 17, 2021

Incident at 10NM PRINCETON BC (CYDC)

A CGPUC Holdings Ltd. Socata TBM 700 (C-GPUC) from Vancouver/Boundary Bay, BC (CZBB) to Red Deer, AB (CYQF), at FL310 and near the Princeton (YDC) very high frequency omnidirectional range (VOR), declared an emergency due to a pressurization issue. C-GPUC conducted a descent to 15,000 feet and returned to origin location.
UPDATE: TSB Report #A21P0012: C-GPUC, a Socata TBM 700 (Series A) turboprop aircraft destined for Red Deer, AB (CYQF), was at FL310 near the Princeton, BC (CYDC) VOR when the pilot declared an emergency due to a pressurization issue. The flight descended to 15,000 feet and returned to Boundary Bay, BC (CZBB).
UPDATE from Maintenance and Manufacturing: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. The organizations Person Responsible for Maintenance (PRM) advised that the cause of the event was the failure of the COMM1 antenna to remain attached to the aircraft. In other words, a loss of pressurization occurred due to the Comm 1 antenna departing the aircraft. When the antenna departed the aircraft, it resulted in lost communications and a 3/4" hole in the bottom of the aircraft where the antenna cable was attached to the antenna, which is what led to the loss of pressurization. A subsequent inspection revealed that the antenna was held in place by 6 x 8/32 sealed screws, which are supposed to go into an 8/32 nut plate that is fastened to the doubler inside the fuselage. The inspection after the incident revealed that the aircraft (most likely) left the factory with #10 nut plates on the doubler, which meant that the screws were never truly fastened and the antenna was held on with PRC/sealant. The aircraft maintenance engineer (AME) was consulting with the manufacturer to find a solution. Service Difficulty Report (SDR) no. 20210223023 was submitted. No further action is required.

Incident at ABBOTSFORD BC (CYXX) (ATM - inaccurate aeronautical information)

At Abbotsford, BC (CYXX), the ground (GND) frequency 121.8 MHz main and back up (b/u) transmit function and the automatic terminal information service (ATIS) frequency 119.8 MHz were unserviceable (U/S) due to construction at the airport terminal that involved telecommunication (Telco) lines. The Technology Operations Coordinator (TOC) was advised. The outage occurred from 1856Z to 1944Z. The tower used the hand-held radio (NICAN) frequency during the outage.

Incident at TORONTO / LESTER B. PEARSON INTL ON (CYYZ) (ATM - inaccurate aeronautical information)

The tower controller instructed a PSA Airlines Bombardier CL-600-2D24 (JIA5020) from Toronto/Lester B. Pearson, ON (CYYZ) to Charlotte, NC (KCLT), holding on Taxiway V west of Runway 33R, to line up for Runway 33R. A Jazz Bombardier CL-600-2D24 (JZA8784) from Toronto/Lester B. Pearson, ON (CYYZ) to Washington National, VA (KDCA), holding on Taxiway D east of Runway 33R, thought the instruction was for them and proceeded to line up. JIA5020 held its position. Both aircraft departed without operational impact. There may have been some interference from simultaneous transmissions.

An American, corporately registered Cessna 650 (N891SH) from Toronto/Lester B. Pearson, ON (CYYZ0 to Charlotte, NC (KCLT) was issued the BETES 2 standard instrument departure (SID) from Runway 05 in CYYZ. After departure, contrary to the SID, N891SH was observed turning right, towards the departure path of Runway 06R. A China Southern Airlines Company Boeing 787-9 (B1243/CSN5052) from Toronto/Lester B. Pearson, ON (CYYZ) to Guangzhou Baiyun, China (ZGGG) was in the process of lining up on Runway 06R, and was held until N891SH cleared the area. When asked by the South Departure controller, the pilot of N891SH claimed to have mis-read the SID, and thought they were ok to turn right. No loss of separation. No impact to operations.

Incident at LONDON ON (CYXU) (ATM - weather observation systems)

At London, ON (CYXU), the temperature, dew point and wind sensors failed, necessitating the use of the Vaisala hand-held unit. Technology Operations Coordinator (TOC) advised. This occurrence also took place the day before, but only included issues with the temperature and dew point. Apparently, the current issue stems from a different problem than the prior days issue. The portable Vaisala was reading up to 4 degrees higher than the air temperature from the other London sites: the local uncertified thermometer, and WSN (the local Environment Canada AUTO 8 station). Environment Canada Forecast called CYXU to advise that the surrounding sites were 3 to 4 degrees lower and they needed confirmation because the higher temperature supported a change in forecast and more potential for convective weather. Impact on operations: increase in workload, and risk of an incorrect forecast based on inaccurate backup.

Incident at TORONTO / OSHAWA EXECUTIVE AIRPORT ON (CYOO) (Aerodrome, runway or taxiway shutdown)

A privately registered Cessna 182F from Toronto/Oshawa, ON (CYOO) to Scugog/Charles Landing, ON (Water) (CHS4) departed from Runway 23, and immediately requested to return for a landing due to an oil leak. The aircraft attempted to land on Runway 12 unsuccessfully and overshot the runway. The aircraft landed safely on Runway 23. The aircraft exited the runway and shut down until the airport manager (APM) arrived. Multiple aircraft held outside the control zone until runway inspections were complete.

Incident at LONDON ON (CYXU)

A Diamond Flight Centre London Inc. Diamond DA 20-C1 (C-GDFO) from London, ON (CYXU) to London, ON (CYXU), inbound from the northwest (NW), was given a clearance. Shortly after, the pilot called on the tower land-line (while still outside of the control zone) and stated that they had lost communications. The pilot squawked 7600 and was once again cleared inbound. The pilot then re-established communications on their hand-held radio and landed without further incident.
