Cyclic, any chance you can post the front page pls? Is the EASB only relevant to EC225 or 332's or all models?
Tks

As HC says, you need a TIPI log-in to see it.

I can see how it looks a suspension bar but Im pretty sure that's one of the Aft Float Support Struts! ��
I think you are right P clips wrong colour for MGB area.

Bizarrely is only applies to EC225 LP helicopters.

The Airbus legal and PR machine obviously doesn't want to shake up its other customers!

MGB fittings

EASB 53A058..Interestingly reminiscent of issues with frame 5295 cracking and fitting loss of torque concerns from 10 years ago.Not,so far,a clear cut case of misplaced or incorrect suspension bar pins.

So Airbus decides to not ground EC225LPs, Shell Norway decides to stop all CHC Norway flights (with S92) indefinately, and now EASA sends out directive saying among other things to check suspension bar for "correct installation".

Starting to sound like maintenance error perhaps. Although this is only speculation at this point.

Tks cyclic, my TIPI currently dont incl 225 but got it!

Maybe this is not the only cause but the scary thing to all off us should be that all French helicopters fly using the stays and between 120, 130, 350, 365, 330, 332 and 225 how many hours were accumulated before now? Yes theres differences between pins vs bolts and nuts vs some split pin other baby pins etc but in principle they all the same for all these hours and years? Not a critisism or finger pointing, just a very sobering thought and reminder to stick to basics.

Very sad for the lives lost, 225 lost and for the engineers involved as I do not know how they are coping and hope they have support threw this regardless off the outcome!

My thoughts as well Mitchaa! The following statement was from sbs.com


"We are as certain as we can be that a technical error caused the accident. We don't think it was due to human misinterpretations," the director of the board's aviation department, Kaare Halvorsen, told reporters on Tuesday.


Thank Kaare, that really clears things up .... throw a smoke bomb out there for now.

why the need to check MGB chip detectors, filter and HUMS data?
Perhaps they read your posts on the value of HUMS

Why does the EASA-AD include more checks than the bulletin from Airbus?

When you encounter a HUMS alert on certain MGB condition indicators, with for example a rising trend, the workcard will often tell you to check the chip detectors and the Oil filter.

If they believed the failure was to do with the suspension rods then why the need to check MGB chip detectors, filter and HUMS data?
Would seem prudent to me that while you are at it just check a few other things?

Looking for and being aware that strange or unusual things can happen is what helps to keep you alive in this business.

Apologies for my previous misidentification of the suspension bar in the first photographs as being the LH bar.

Identification was based on the EC225LP IPC which I now see is wrong.

Based on the Aircraft Maintenance Manual and the EASB it is in fact the RH suspension bar.

Just goes to show even the manufacturer has problems getting it right.

Am I right in thinking that there is an engine in the way of that front mounting? And is that the explanation for the timings in EASB?

Probably because they feel that more checks are needed that those recommended by Airbus. All of which points to the consideration of a number of failure scenarios.

The EC225 and AS332L2 MGBs share a lot of commonality. The major difference is the flared housing on the 225 MGB vs the conical housing on the 332. The main module is very similar, and the epicyclic is effectivley the same on both types. Given the commonalities AS332 MGB/epicyclic failures shouldn't be discounted.

I hope you are seriously kidding. Being an advisor and making such biased and unverified statements doesn't bode well. That is profoundly unprofessional. If you were an advisor working for me your contract would be terminated here and now and I would send out a warning to any related/known other company about avoiding your service under any circumstance.
