A Royal Canadian Air Force CH-149 Cormorant search and rescue (SAR) helicopter crashed at the 9 Wing air base in Gander, Newfoundland and Labrador, the Canadian armed forces confirmed.
There were six crew onboard the helicopter at the time of the crash on March 10.
While four members have already been released and are with their squadron members, two members are currently in hospital receiving treatment, according to the service.
The extent of their injuries or the circumstances of the mishap remain unclear.
The air force only said the helicopter was conducting hovering maneuvers at the Gander airport prior to the accident.
Photographs of the crashed helicopter which appeared online showed the airframe on its side, with its tail and wings apparently missing.
An investigation into the accident is currently ongoing, coordinated by the country’s Directorate of Flight Safety.
The CH-149 Cormorant is a long-range helicopter dedicated to search and rescue. It can operate in severe conditions, making it ideal for Canada’s challenging geography and climate. The helicopter can carry up to 12 stretchers or a load of 5,000 kilograms.
