the current practices of ignoring or refitting U/S parts, or conducting unauthorised repairs, will be deemed illegal
Surely such practices are contrary to existing Military Airworthiness Regulations already, Riga? If not they damn well should be, unless in accordance with the MEL! It's a big enough challenge to ensure that the military be supplied with aircraft that meet Military Airworthiness Regulations which patently does not necessarily happen now. That the military should then make them unairworthy by such practices is totally unacceptable, genuine operational requirements in wartime conditions excepted and open to MAA scrutiny.
