The operator of the police helicopter that crashed through the roof of a Glasgow pub last Friday grounded its entire fleet of Eurocopter EC135s for a time last year amid serious concerns about rotor hub shaft cracks, according to public records.
Accident investigators in the U.K. haven’t indicated that the grounding played a role in the crash, which claimed the lives of nine people and injured dozens inside the packed pub, but say the issue nonetheless will be one area they and Eurocopter technical personnel will consider as the search for clues into what went wrong continues.
