terminus - I am only going by what the AD says. It seems unlikely that with all teh discussion that have been going on between CAA and EASA, that a new AD would be published that doesn't satisfy the CAA. Where have you seen the information that makes you say what you do?
Perhaps the confusion is the difference between "increased MOD 45 monitoring" - by means of analysing the groundstation data at 3 hr intervals or whatever. This still require the ultrasound inspections.
Versus
The MOD45 cockpit monitoring. Once this is in place, the requirement for the ultrasound, which is contained in para 2 of the AD as I said, is removed. The relevant sentence in the AD para 4 is:
(4) Modification of an EC 225 helicopter as required by paragraph (3) of this
AD constitutes terminating action for all the requirements of paragraph (2)
of this AD.
my bold
SAS, yes that is the intention, but that aspect is not yet covered in the AD. I guess they can't mention it in the AD until its certified.
