On final approach to Port Albert, the twin engine aircraft hit the ground short of runway threshold. The undercarriage were sheared off and the aircraft slid for several yards before coming to rest. While all five crew members were unhurt, the aircraft was damaged beyond repair.

While cruising at an altitude of 7,000 feet by night and in marginal weather conditions, the aircraft hit the slope of Mt Cheam located near the Fraser Valley, in the region of Chilliwack. SAR operations were conducted but eventually suspended after few days as no trace of the aircraft nor the 13 occupants was found. The wreckage was spotted by hunters in August 1943.

One minute after takeoff from Gander Airport, while climbing by night, the aircraft stalled and crashed in a wooded area, killing all four crew members. They were engaged in a transatlantic delivery flight to England.

The seaplane left Dartmouth on a maritime patrol flight over the North Atlantic. The crew made a stopover in Sydney before continuing to Torbay, north of St John, Newfoundland. En route, in unknown circumstances, the aircraft crashed into the Trinity Bay, off Port Rexton. The aircraft was found floating upside down few hundred yards off shore by local fishermen and all five crew members were killed.

The pilot was attempting to land in the Saint Laurent River in strong winds. Upon landing between Longue-Pointe-de-Mingan and the Anticosti Island, the aircraft went out of control and sunk. Five crew members were killed while four others were rescued.

Shortly after take off from Abram Lake, south of Sioux Lookout, the engine failed. The aircraft stalled and crashed on the shore. No casualties.

The twin engine aircraft left Patricia Bay Airport in the early morning to perform a navigation exercise over the Vancouver Island. En route, the crew encountered poor visibility and the aircraft failed to return. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the crew was found. On October 25, 2013, almost 71 years later, hikers found the wreckage in a hilly and wooded area located near Mesachie Lake.

Sgt William Baird, wireless operator,

The aircraft was piloted by Captain Secord when it crash landed in a bog in a remote portion of the Little Macatina River, in southwestern Labrador. The pilot made a forced landing due to fuel shortage. The aircraft was on a reconnaissance mission and landed due to low fuel. The crew were rescued three days later, but the aircraft was abandoned, most likely due to the remoteness of the crash site.
