Cathay Pacific Grounds All A350 After TrentXWB Engine Fire

[ATLcrew]

No, but I know what you say about me...

Glad to help. The sayings are as follows: even a broken clock is correct twice a day, and even a blind squirrel sometimes finds an acorn.

You're welcome.

Ah, welcomed at last.

I guess this is your version of credit where credit is due (though the AD prediction was sort of a no-brainer IMHO).

You can't possibly be the same ATLcrew who chastised BoeingBobby for being disrespectful.

[BoeingBobby]

No, but I know what you say about me, which is not always deserved. What was that you were saying to BoeingBobby about respecting others rather than just writing them off as idiots?

Or liars!

[3WE]

…and forum members sometimes crave popcorn.

You're welcome.

Yeah, thanks.

Malaysia Airlines claims to have found the same fault on one of its six A350-900s. I believe this would out of scope for the EAD currently.

The AD is directed at the Trent XWB-97, which I think is only used on the A350-1000. This appears to be an easy external engine inspection and a quick fix, so I question the wisdom in limiting it to just the -97. Hopefully it will be extended throughout the XWB range. Safer than sorrier.

An update from 9/19:

Since EASA issued AD 2024-0174-E, in-service and in-shop inspections have identified that a specific cleaning process available during engine refurbishment may lead to fuel manifold main fuel hose degradation.

Additionally, it was determined that Trent XWB-75, Trent XWB-79, Trent XWB-79B and Trent XWB-84 engines were also the subject of the suspect cleaning process, and therefore are potentially affected by the unsafe condition addressed by this AD.

Prompted by this development, the affected cleaning process was discontinued by maintenance organisations as instructed by Rolls-Royce Maintenance Repair and Overhaul Quality Alert No. MRO 2024-21 issue 1. Additionally, Rolls-Royce issued the NMSB, as defined in this AD, to provide repetitive inspections for populations of engines potentially affected by the suspect fuel manifold main fuel hose cleaning process.

And:

In addition to the anomaly identified on the No. 17 secondary fuel manifold hose [on the incident aircraft], five additional secondary fuel manifold hoses were found to have either frayed metal braids or collapsed structures inside the hose.

Updated EAD with broader scope. Compliance date is now October 3.
