All Sea King helicopters grounded after N.S. incident

All Canadian Sea King helicopters have been grounded pending an investigation into an incident late Monday night at a Canadian Forces Base near Halifax, the Department of National Defence has announced.

A Sea King helicopter struck the tarmac with its main rotors just before midnight Monday during a landing at CFB Shearwater in Eastern Passage, N.S., after a training flight.

DND confirmed that the helicopter experienced a “flight safety occurrence.”

The CBC’s Paul Withers reports a hangar on the air base was also damaged by the debris. The rotors were sheared off.

DND said the four crew members aboard the aircraft were not injured.

CFB Shearwater is located across Halifax Harbour from the city itself.
