I cannot vouch for the conduct of RAFAT as a unit, because I have no personal knowledge of it. What I would say is that the criticism made of it in this SI bears a familiar ring from previous SIs/BOIs. What did the Mull pilots have for breakfast? Did they have any at all? In that case it acted as a diversion from the elephant in the room, that the aircraft was grossly unairworthy and was flying under an illegal RTS.
Mull showed clearly that lying, stealing, and cheating existed at the very top of the RAF High Command. Illegal orders were issued by Air Rank Officers who are still not condemned, only those who refused to obey them are. If such an example is set by those in High Command, it is only a matter of time before such practice appears at a unit near you!
RAFAT may well need attention in that regard, again I do not know, again I take what the MOD says, through its MAA subsidiary, with a pinch of salt. What does need attention is the RAF High Command. By protecting their predecessors they continue to compromise Air Safety. While the UK Military Airworthiness Authority remains in house, vested in the MAA (see what I did there Easy Street?) that will continue to be the case. While the MAAIB remains in house and within the MAA, it will continue to be the case.
The MAA has been judge and jury in its own regard. This aircraft was unairworthy. That is the elephant in the room!
