That would be all well and good if an 'unacceptable' recommendation from Boscomber always meant no RTS from ACAS.
But it doesn't. ACAS can, does, and has signed MAR's for aircraft deemed unacceptable by Boscombe Down.
If an aircraft can get an RTS/MAR without Boscombe's formal recommendation, then there is no automatic blanket answer, and it has to be judged on a case-by-case basis.
So why not the Chinook HC3?
