On 2 June 2016 , following the crash of an H225 in Norway which revealed a potential safety issue with the main rotor assembly , the EASA issued an emergency airworthiness directive that grounded the H225 fleet ; by July 2016 , 80 per cent of the worldwide fleet had been grounded as a result , while some operators such as the French military continued to operate its fleet . In October 2016 , the grounding order by the EASA was lifted ; some countries , including the United Kingdom and Norway , chose to maintain operational restrictions for the type . Norwegian operator Statoil , who had contracted the CHC H225 which crashed , maintained it will not return to using the helicopter even if restrictions are lifted . The company has instead relied on the Sikorsky S-92 to meet its needs since the crash . By December 2016 , three separate lawsuits were filed by separate H225 operators , claiming that the type had been sold in a defective state due to the flaw being " inherent "
