UA Temporarily Grounds Boeing 772 (PW Power); returning to service: late May 2022
 

Now Japan is grounding all 777's? Overkill, I think. Unless the power plants are P&W too and they feel there might be a problem within.

Looks like just 777s with P&W engines. Shouldn't impact 777-200LRs (don't know if Japan has any flying there) or 777-300ERs as those only have GE engines.

I wouldn't be surprised to see other countries issue a temporary grounding, namely because the cost of doing so is relatively low right now given how many aircraft are parked and others underutilized. I'd imagine there are very few airlines that would be impacted beyond the immediate short-term issue of getting their other aircraft and crews to take over the flying.

EDIT: Wiki shows about 10% of all 777s have P&W engines, and it appears a decent portion of those are in storage already. I'd expect 100ish planes grounded if they grounded all PW4000 777s.

Nope, Japan is grounding only the PW power 772 and 773, it is not overkill as JL had a PW power ex JD 772 suffer the exact same problem just two months ago, so this is a pattern but not a one off incident, in a matter of fact this happened 3 times in 3 years already when you add on the sister ship to yesterday's 772 suffer the same problem back in 2018.

This may now be worthy of a second thread, but UA is now removing all the P&W 772s from the active fleet to undergo additional inspections. Will likely result in some pretty major shifts, in particular on the Hawaii routes.

Hardly surprising the FAA are grounding them for inspections.

Swapped me to a 777-300 on my SFO-HNL flight Monday. Very happy.

24 active + 28 in storage

Good for UA for getting ahead of this. Where is PW?

Probably shouldn't have pushed back those A350 deliveries

$BA gap down tomorrow is inevitable

Please change your title, as only PW power 772 affected, UA also have sCO 772 and 77W, these are GE90 power and unaffected

Yes, that title got me alarmed.

Fortunately my upcoming '772' flight (per reservation summary) has been assigned a 773 (per flight status) for at least a week. :)

Changed but I think it requires a mod to change title on the post list. My bad for forgetting to specify planes with PW engines only.

Thanks. Hope a moderator can update the thread listing title soon.

There is some related discussion in the UA328 thread.

Maybe will move here.

FAA is 'calling for' more thorough inspection of PW engines, and Japan has grounded PW 777.

Actually, only the mods can change a thread title. You'll want to alert mods to your own post 1 ("report bad post", even though we know it's not bad per se) so they can change it.
