JTO:-
The SI did what it was directed to do; nothing more and nothing less. It was rightly commended by the DG MAA.
Which makes my point succinctly. It should not be up to the DG MAA to commend an investigation by the MAAIB into an airworthiness related accident, but to jolly well get on and carry out its recommendations. One is reminded of the BA737 tragedy at Manchester, when training had to be greatly modified and much extra kit installed in all aircraft on the UK register above a certain size. All that was recommended by the
independent AAIB and enforced by the
independent CAA on all UK AOC holders.
Am I alone in finding your quote disturbing, in the light of previous BoIs featured in this Forum? They did what they were directed to do. That was the problem.
