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.

UPDATE: TSB#A16O0075: C-GDJH, a Learjet 35A operated by Keewatin Air LP as flight KEW102, was on a Medevac flight from Iqaluit, NU (CYFB) to Ottawa/MacDonald-Cartier Intl, ON (CYOW). While in cruise, the crew received a LOW HYD annunciator light. The hydraulic quantity was also noted to be decreasing and pressure was down to 1000 psi. The crew contacted the operator?s maintenance who advised that airport personnel at CYFB found evidence of hydraulic fluid where the aircraft had been parked. The crew followed QRH procedures and declared an emergency, as well as requesting a tow vehicle after landing in CYOW. After the landing gear was extended on approach, the hydraulic pressure dropped to zero while the main landing gear indicated two red unsafe lights with two green lights. The crew followed QRH procedures once more and extended the landing gear manually. The standby pump was used to lower the flaps and regain some hydraulic pressure. ARFF was on standby for the landing. After touchdown, the brakes were operational, however the spoilers did not deploy. The aircraft was able to exit the runway without assistance from the tow vehicle. Post flight inspection by maintenance personnel revealed a leak from a hydraulic pressure line due to chafing from a worn Adele clamp. The chafing created a small hole in the line which allowed the hydraulic fluid to leak. The line was replaced and a full inspection of all clamps was performed by maintenance.
