Canada has 26 of the ship-borne maritime helicopters, with a final one slated for delivery this year. The $5.8-billion fleet is normally used to provide air support for the Royal Canadian Navy. Their missions include surface and subsurface surveillance, search and rescue, and anti-submarine warfare.

'On May 1, the Commander of 1 Canadian Air Division ordered a temporary pause to flying operations for the CH-148 Cyclone fleet, after questions emerged in late April about whether various spare parts for the aircraft were potentially in use beyond their service life. The temporary pause to flying operations was lifted as of May 27,' Kened Sadiku, who speaks for the Department of National Defence (DND), said in an email.

'Certain aircraft components have a defined service life to ensure continued safety and airworthiness. Because using parts beyond their defined service life would pose risks to the safety of personnel and equipment, the decision was made to temporarily pause flight operations until certainty is regained.'

DND, the military and Sikorsky, which manufactured the helicopters, 'have been working together to identify potential parts of concern. This includes components of the Cyclone's landing gear, tail rotor driveshaft flange and auxiliary power unit, as well as engine parts,' Sadiku said.

The Cyclone 'fleet is currently facing some challenges, such as aging datalink systems as well as sensor and other capabilities that are overdue for important upgrades,' he said. 'Specific details, however, cannot be provided for reasons of operational security.'

Military and government officials 'are working together with industry partners to determine a way forward for the aircraft and the capabilities it supports,' Sadiku said.

'The Cyclone remains capable of supporting Royal Canadian Navy operations and will continue to do so for the foreseeable future.'

Sadiku wouldn't confirm Sikorsky has put a hefty price tag on replacing the Cyclones' ageing datalinks — used to communicate digital information such as radar images to other aircraft, warships and shore bases. 'The datalink upgrade project is still under evaluation, as such, schedule and costs are still being negotiated.'
