The helicopter was out of service for over a month during summer 2018 as a technical failure was investigated . Flight operations were also suspended for two weeks in August 2018 as the aircraft , vehicles and airbase buildings were examined to ensure no contamination resulting from the 2018 Amesbury poisonings was present . The aircraft did not respond to the poisonings as it was again grounded due to a technical failure , but there was concern that traces of Novichok may have been transferred onto equipment used by critical care paramedics who responded in rapid response vehicles
