I am going through exactly the same thing, different maintenance lot. IO540 spot on in that the CAA will do NOTHING.
I had a conversation with senior at Gatwick last week, who hinted it is all my fault, the second time this has been insinuated.
Best of luck, if owners actually knew what was going on, and took an interest
then all hell would break loose. Problem appears that a lot of them are just glad to get the aircraft back in the air, at cheapest cost, illegal or not.
Dont think this is libel
