The Royal Canadian Air Force has resumed flights of its Sikorsky CH-148 Cyclones, multiple Canadian news outlets have reported. The helicopters were grounded about one month after an incident in March, when an aircraft experienced what reports have called a “severe bump” during a training flight.
Although the aircraft was able to land safely, Sikorsky and the Air Force launched an investigation. Reports have said the investigation found the cause of the incident was a software issue in the flight control system. Safety measures have reportedly been put in place pending the software upgrade, which would be developed by Sikorsky over a series of months. These measures would be subject to change as the Air Force progresses toward resuming training, test and evaluation, reports said.
CTVNews and Global News quoted Col. Peter Allan, wing commander of the Shearwater base in Halifax, Nova Scotia, as saying, "It's more about modes of the computer they can employ while in particular flight mode ... at the end of the day, it doesn't affect our ability to do training and operational testing and evaluation.”
