EASA has certified a redesigned vertical bevel gear shaft for the Airbus Helicopters EC225, which was grounded for nine months in 2012 and 2013 after a series of in-flight failures. Manufacture of the redesigned gear shaft is under way for production aircraft and retrofits, with first installations (for both applications) planned for this year’s second half.
