TSB Report #A21P0088: C-IWBN, a privately operated Murphy Rebel advanced ultralight, was conducting a flight from Cranbrook/Canadian Rockies, BC (CYXC) to an abandoned airstrip at Sage Creek, BC, with 1 pilot on board. During a slow descent at 1300 feet AGL, the engine (Rotax 912ULS) made an escalating high pitched whine that was followed by a complete engine failure within approximately 5 seconds. The pilot performed a forced landing on a logging road without engine power. The left wing contacted trees during the landing roll, instigating a ground loop which caused the aircraft to veer off of the logging road as it came to a stop. The pilot was not injured and the aircraft was substantially damaged. An engine teardown found that the piston failed in the #2 cylinder. The annual inspection, including an engine borescope and dynamic vibration analysis, was completed 3 flight hours prior to the accident, with no faults found in the engine.

A White Bear Industries Ltd. Robinson R44 II (C-FWBL) on a flight from Terrace, BC (CYXT) informed the CYXT flight service station (FSS) that it had conducted an emergency landing due to an aircraft issue. The aircraft was damaged upon landing. A helicopter was sent to pick up the pilot and passenger. No impact on operations.
UPDATE: TSB Report #A21P0046: C-FWBL, a privately operated Robinson R44 II operated by White Bear Industries Ltd., was enroute from Lakelse Lake, BC, to Fort Nelson, BC (CYYE) with one passenger on board when the pilot received a low main rotor RPM warning horn and light, with both engine and main rotor tachometer needles decreasing. The pilot performed a forced landing on a mountain logging road approximately 15 NM NE of Terrace, BC (CYXT). The pilot noticed while in the auto-rotation descent that the reciprocating engine RPM was fluctuating (Lycoming IO-540-AE1A5, 6 cylinder, fuel injected). During the flare to touch down, with collective and aft cyclic application to arrest the descent and forward motion, the helicopter skidded forward for about 15 feet on the gravel road. The helicopter remained upright on its skids, and both the pilot and passenger exited with no injury. The helicopter suffered substantial damage when the main rotor struck the tail boom during touchdown. The tail boom remained only partially attached to the rest of the structure by the internal driveshaft assembly connected to the tail rotor gearbox. Maintenance was contracted to inspect the helicopter drivetrain and initially could not find or replicate any defect that would suggest a mechanical malfunction or explain the low main rotor RPM reported by the pilot.

TSB Report #A21O0053: A privately registered, amateur-built Cozy Mk IV was conducting a VFR flight from Carp, ON (CYRP) to Arnprior, ON (CNP3). After announcing their landing intention on 122.7 MHz, the pilot was on final for Runway 28 when they saw a truck towing a floatplane, a privately registered Cessna 172I, on the North side of the runway and proceeding to the runway from Taxiway A. As the airplane continued the final approach, the pilot noticed the truck with the airplane in tow proceeded to cross the runway and move toward the seaplane ramp access road. The Cozy Mk IV aircraft landed on Runway 28 and was still on its main landing gear when passing the floatplane on the trailer, lowering the nose shortly after. The truck towing the floatplane was not equipped with a VHF radio and the driver did not see the aircraft on final approach when they stopped at Runway 28. The truck driver saw the arriving airplane when they were already on the runway, and accelerated to clear the runway. The Cozy Mk IV aircraft completed the landing roll without further incident.
UPDATE: Aviation Incident Report #17182: A privately registered, amateur-built Cozy Mk IV from Carp, ON (CYRP) to Arnprior, ON (CNP3) was conducting an overhead approach into CNP3 from the north, with radio call over the city of Arnprior, at 1600 feet. When the aircraft was over CNP3 at 1400 feet, they made a second radio call immediately following the Skyvans radio call. They entered the mid-downwind for Runway 28 at 1400 feet and made the radio call accordingly. The aircraft lowered its landing gear and called base and then final. They saw a pickup truck towing a privately registered Cessna 172I on the right side of the runway (north) moving south toward the runway. The aircraft continued its approach and the truck did not stop at the edge of the runway. The truck continued across the runway approximately 1200 feet in front of the aircraft as it crossed the threshold of Runway 28. The aircraft moved a few feet to the right of the centreline to ensure no contact during braking. The truck continued on its route to the seaplane ramp and did not stop. The truck had no flashing light and did not stop and check for arriving/departing aircraft before crossing the runway. The truck did not make any radio calls on 122.7 MHz.
UPDATE: Aviation Incident Report #17182: Arnprior, ON (CNP3) synchronized the pilots in flight video with CNP3s 4K surveillance cameras. The vehicle pulling the trailer does come to a complete stop prior to entering the runway. The camera used in the cockpit is a wide angle lens, making things appear further away than they are. Observation: The pilot was still on their main as they passed the trailer, lowering the nose just shortly after.

TSB Report #A21W0007: A privately registered Bellanca 7ECA was operating on a VFR flight from Airdrie, AB (CEF4) to a private airfield near Rimby, AB (6NM SW). While approaching the airfield to assess the field condition, the aircraft was maneuvering at low-level and inadvertently struck a power line which ran across a road. The power line was severed and the pilot immediately landed the aircraft straight ahead on the road. The pilot, who was the sole occupant, received no injuries. After landing, the aircraft was taxied into the farm yard, where it was shut down and secured. Aircraft damage was limited to the cowling and propeller.

TSB Report #A21W0011: A privately registered Piper PA-22-108 was operating on a local flight from Labrie Field-Ponoka Industrial, AB (CEH3). The aircraft departed CEH3 at 2050Z (1350 local) and flew locally for approximately 35 minutes in cruise flight, at 4000 feet ASL, when the engine (Lycoming O-290-D) rpm suddenly decreased from 2300 rpm to 1500 rpm. The pilot applied carburetor heat, checked both magnetos and switched fuel tanks; however, the engine rpm did not improve. The pilot initiated a forced approach 21NM NE of CEH3. While on approach to land, the pilot attempted to re-apply power and the engine rpm increased to 1800 rpm, which lasted approximately 20 seconds before engine power reduced to 1300 rpm. The pilot observed that the oil pressure was in the green band. While reapplying power, the aircraft overshot the intended landing area, and continued towards the next field. While approaching the next field, the aircraft crossed under a power line and over a road. At this time, the pilot observed a loud thud as the vertical stabilizer struck the power line. The pilot continued to land on the field and slid into a high wire fence, striking a fence post. The fence wire slid over the cowling and broke the windshield before the wire sheared. The aircraft came to rest leaning to the right, with the right wingtip resting on the ground. The pilot, who was the sole occupant, was uninjured. The emergency locator transmitter (ELT) was not activated. The aircraft received damage to the propeller and engine cowling, and had a bent left wing strut and windshield. Inspection of the engine revealed oil on cylinder 1 and blistered paint at the base of the cylinder. The engine contained 3.5 quarts (qts) of oil and it was observed that the engine exhaust was dripping engine oil.
