Not necessarily. Think about it, what variants of the H225 are still being flown and by whom? What was the 'material' fix by AH that enables this? Convincing the offshore market of course is a different thing altogether. AH might only have to wait for the AIBN report (and EASA approval).

First they have to properly understand why the gears didn't nearly last as long as they predicted. That is a prerequisite for any potential fix. My understanding ist they haven't really understood the mechanism behind.
Depending on the exact cause it might be in the best case just a re-design of the epicyclic gears or -more realistically- a bigger re-design of multiple components in the MGB. Worst case would be a complete re-design of the MGB although I doubt this will be necessary.
Most likely is the second case. This would probably take somewhere between 6 and 12 Months. But these 6- 12 Months would only start once they found the cause.
It was their big mistake to stop digging at some point after G-REDL.

Those operators who fly their own H225's such as Bristow must be in line for substantial 'loss-of-revenue' compensation. Same probably applies to the lessors. This sad saga will run into millions of $.

I said
It is imperative that Eurocopter get the EC225 back in service.

It is intolerable to customers to have Sikorsky have a monopoly and a simultaneous shortage of airframes as that will just drive cost up for the oil companies at a time of low oil price.

Ignore the petitions! With oil workers putting up with 30% pay cuts and more time offshore they will take whatever helicopter their company aviation advisor deems safe enough, just as they have done before after past accidents.

Obviously the advisors have to play being let-down with Eurocopter for the moment, to divert attention from their own past aircraft selections, but the world goes on.
And the only thing Industry Insider contradicts is that S-92 prices are going up.

II - I do know the trick of telling a supplier the other guy is cheaper! Amazing how often it works to beat down the lowest bidder
Have you tried telling them the other guy will air freight the S-92s in for free?

Do though remember old boy I'm retired now. Which is also why twisted wrench I still think of EC/AH as as Aerospatiale and the 'H'225 is just a marketing name.

This story has taken a turn very reminiscent of the Chinook if you remember that far back.

Unfortunately for UNITE, the workforce isn't as 'unionised' as they would like.

If the second type of epicyclic design has never failed (which I believe is the case - please correct me if I'm wrong) then a redesign might be unnecessary. The fundamental problem, as you rightly point out, is that the investigation has so far been unable to establish why the first type of epicyclic design failed and why it was not detected in advance. Without that we can't conclude that moving to the type 2 design will solve the problem. It is these two uncertainties that have blighted the aircraft's reputation and are the major factors preventing the rehabilitation for the brand.

The cause of the Chinook Crash was determined and effective corrective action taken.

That so far is not the situation with the 225 at this point in time.

Total is about to resume 225 crew change flights with Omni in Brazil.

Unite doesn't issu such a statement without reason,that means that NS operators are on the way to reintroduce the 225.

That's being brought back to a contractual level of serviceability to hand back to the leasing company.

There are a few which have to be brought up to airworthy spec for return to lessors, under the CHC Chapter 11 they were not required to be airworthy.

There are very few in the NS who were about at the time of the Chinook crash, or who care about the event today.

Oh yes there are. The biggest proportion offshore is 50, 60, and some 70 year olds with long memories

And since none of them are likely to be offered a ride in a Chinook anytime soon I'm sure they spend little time comparing failure-modes.
