I can totally agree with Boeings stance, they are the design authority for the Chinook, to circumnavigate that both undermines their authority and then allows things to be embodied on the aircraft that they have no say or control over.. And let's face it, that would have been know when purchased.
Having said that at contracts being signed the MOD accepted that Boeing were the design authority, they are the people they should be working with on all aspects of Airworthiness, to simply say "ouch we are not paying that' would get your EASA Approvals withdrawn in the Civil world...
One does wonder the legal ramifications if a Chinook crew is killed due to MOD negligence under failing to comply with Airworthiness requirements laid down by the manufacturer.
Incidentally wasn't one of the major advantages of the Jaguar that the design authority had transferred to the MOD, thus allowing upgrades to be carried out both cheaply and quickly?
