Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many aircrew were deemed negligent by reviewing officers despite contrary findings by the RAF Board of Inquiry between 1983 and 2011.

The information requested is not held in the format requested and could be provided only at disproportionate cost. Although an incomplete collection of 550 Boards of Inquiry (from 2008 redesignated Service Inquiries) into RAF flying accidents from the period in question is held, there is no central document recording the outcomes.
