Group Flight Safety Staff had a duty to comment on each and every incident and accident from a Flight Safety perspective. This would require consultation with the Air and Engineering Staff for that type of aircraft -irrespective of any assessment of Human Failings. It could also require consultation with Medical, Administrative, Air Traffic Control and Movements Staff.
This process would have been repeated at STC level and, in this particular case, it was repeated at MOD level with the final review carried out by CAS.
