My 2 Cents....
This doesn't sit with me well - but Bose has it here.
Yep - MP screwed up and yes, he knows it. But he also has commented on the fact that he feels the CAA should come down his 'student'. Nope....sorry, but that is MP's responsibility.
As has been pointed out many times this was, I believe, single crew - there is no P2 function and even if there was it would be entirely at the behest of the aircraft commander (MP) or 'company' (the school) to insist on whatever corrective action (punishment) they felt necessary.
As commander, MP is responsible for the safe and propper conduct of the flight and from a commercial point of view he has a responsibility to his customer (the other pilot) to ensure that learning points are, well, exactly that. Sad fact, but the customer has paid to be 'watched' to ensure he could conduct a flight safely. MP failed in this respect.
PPP,PPP
Sad, yes.
Ballsy to admit the original error, yes.
Naive to expect anyone to share the blame? very much so!
