I just had an interesting thing happen. I just had my flight canceled (that was already canceled from today, which is a whole other drama filled story) and spoke with an agent about it. It's UA788 EWR-SFO on tomorrow the 20th (https://www.united.com/en/us/flights...-20/EWR/SFO/UA). The 1k agent I spoke with said there was some FAA filing issue and so they grounded a bunch of 777s around the world which I found curious, especially since they rebooked me on... Another 777. Anyone heard anything about this by chance? The whole thing seems odd.

MIscommunication w/ agent referencing previous grounding? The 777s that were grounded at that time had a specific engine. If grounding has again been put in force, maybe only certain 777s have been taken out of service, not all, allowing your subbed 777 to fly.

Yeah there's no real info and that's totally plausible.

Just poking around though, I'm occasionally seeing other routes with a 772 getting pulled with the same cryptic message. Could be a total coincidence though, but yeah thought I'd ask and see if anyone's heard anything.



Oh I should have clarified, they rerouted me and my new leg is on a 772. My original leg in the original post remains canceled.

Something's definitely up...in addition to the OP's flight, the following PW 772ER flights this evening have been canceled for MX reasons so far:

UA1666 SFO-EWR (N796UA)
UA918 IAD-LHR (N791UA)
UA932 IAD-FRA (N788UA)
UA2059 SFO-EWR (N786UA)
UA30 EWR-MUC (N785UA)
UA2215 EWR-LAX (N782UA)
UA915 IAD-CDG (N224UA)
UA149 EWR-GRU (N227UA)
UA106 IAD-MUC (N216UA)
UA148 GRU-EWR (N217UA)

UA70 EWR-AMS (N799UA) took a 3.5 hour delay and is currently taxiing to the runway. The PW 772HDs and the GE 772ERs don't seem to be affected at this time.

Paperwork snafu perhaps?

An unknown/unverified source posted this on Twitter:


Update: UA70 EWR-AMS has since taken off, so whatever paperwork snafu must've been resolved for that one aircraft.

A 772 is a 777 (777-200). A 773 is a 777 (777-300).

bob_the_d

Ah yeah that's why I thought it was odd. The agent said there was an FAA notice grounding 777-200's which is what canceled my original EWR-SFO leg, and they rerouted me to EWR-NRT which is still on a 777-200. It's just generally leaving me with more questions than answers, I guess.

Wow, that's a lot of affected px.

There was a quick weather event which rolled through the area this evening around 6pm. Hope UA doesn't back out of proper compensation.

Possibly th4e new grounding is due to an incomplete documentation that an agreed FAA repair (sic) action had not been fully complied with

Is it all PW 772s or a subset?

this morning the PW 772ER is flying however, UA2678 using N220UA for ORD-SFO is in the air currently

It seems to be/have been a subset.

N226UA, the frame originally scheduled to operate OP's UA788 EWR-SFO this morning, is also airborne as UA1755 EWR-IAH. Hopefully these are indications that the issue is fairly minor and that all frames can return to service today or tomorrow.

I am supposed to be outbound on a 772 today. I noticed cancellations stacking yesterday and again today. I called the GS line and the only information they have have about cancellations are due to the queen's funeral. Three different conversations in the last 24 hours yielded no useful information. Two if the reps were not even aware of cancellations, the third said they sent a question up the line, but no response back. With this disruption, mostly on international routes United needs to come clean.

Could this be related?
WASHINGTON, Aug 2 (Reuters) - The Federal Aviation Administration (FAA) on Tuesday issued an airworthiness directive for all Boeing (BA.N) 777 airplanes over safety concerns.The directive was prompted by high electrical resistance within the gust suppression sensor because of corrosion. The FAA said the gust suppression function is a non-essential feature that provides a minor improvement to ride quality during lateral wind gusts at low airspeeds.

Airlines must disable the gust suppression function within three months or before 75,000 total flight hours. The directive requires disconnecting connectors and capping and stowing wires attached to affected modules.

The directive, which is effective immediately, covers 279 U.S. registered 777 airplanes of U.S. registry. The FAA said Boeing is "currently developing a modification that will address the unsafe condition", and once the change is approved the FAA could issue another rule.
