Commander says it will take six months to fix software problem that grounded air force's helicopters

A commander at the Shearwater base in Halifax says it will take about six months to completely fix a software problem that grounded the air force's Cyclone helicopters.

Colonel Peter Allan, who is wing commander at Shearwater, says the fleet of CH-148 helicopters that are used to train crew resumed flights last month after being grounded in March.

The Royal Canadian Air Force had said the  helicopters experienced a "severe bump" during a training flight on March 9th, causing a sudden descent before the pilot safely landed.

Allan says the problem was found to be a software issue in the aircraft's flight control computer, which caused a sudden restart of the system.
