Anyone know what the latests A/D is on the RR 522/524 engines?
Completion date has to be done by Aug 25 2006 my sources tell me.
Was told this was at a costs of 70,000 usd per engine.
Any idea how long it takes to accomplish this and whats involved?

411A

Yes indeed, 'tis fast approaching, this year for -22B engines and (IIRC) next year for the -524 varient.
HSGB and shaft location difficulties, some have complied already, some haven't.

So I guess the drop dead date is near.
What are the chances of companies getting an extension on this A/D?
Bet some of them are not aware this option may be available.

411A

There may well be no extension possible, as these AD's were published some time ago, and operators were given ample time to comply....or at least that was the theory.
Time will tell.

There have been a couple of HSGB failures/fires, and I do personally know of several fan locator bearing failures (I had two), but no shaft migration incidents that I know of...

I would think there is no chance of an extension, as a tech services Engineer I have only ever seen one extension which was for B757 flap angle gear boxes, this extension was granted as the only company that made Them went out of business so none were available.
is it this one? if so its only$1400 to comply with. http://www.airweb.faa.gov/Regulatory...3?OpenDocument

Thanks Matkat and 411.
Not sure if this is the same A/D I was told about but will research further.
Some of the areas seem the same.
Will find out the exact A/D and reply.

AD 2003-14-21 applies.

Any idea if the local Thai DCA can grant an extension overiding the FAA on this matter?
Thats what we are being told down here.

411A

I sincerely doubt it.
Having said that, perhaps if the right pockets are filled......
One never knows.

matkat

Earl, yes They can this is only because the FAA A/D was not issued by the state of manufacture if the CAA had issued this A/D (and maybe They have under a diffrent number) then it would be mandatory and no extension would be possible.

Interesting, I always thought that any state could ignore issuing their own AD if not under another states regulatory agency.

What I think that I'm saying is that if the Thai's regulatory agency agrees to abide by CAA regulations, then they must enforce a CAA issued AD. However with that said, if the AD was issued by the FAA then it's up to other states to decide whether to enforce it. from my underatanding most states other than the US, Europeans, do accept either the US or European ADs, but not necessarily both.

With that said, it would in my view be of significant interest if the CAA has not accepted and endorsed an AD issued by the FAA, thus leaving many other states to rely on their own.

I hope I haven't confused this issue too much
