Which flights are you seeing canceled today? I haven't checked this morning, but the only canceled flights today that I saw last night were the return legs of aircraft that were supposed to fly to Europe last night, e.g., LHR-IAD was canceled today because last night's IAD-LHR was canceled.

Hopefully they have multiple lines of inspections going and can get them all done within the next few days to minimize further disruptions. We shall see how this evening's operations go. So far UA875 SFO-HND (N787UA) seems to be a go, and UA79 EWR-NRT (N227UA) departed EWR but is currently diverting to ORD for reasons unknown.

Update: good news:

Unrelated to the inspections. This was planned prior to departure and its a fuel stop due to weight & balance issues out of EWR.

I guess it was a borderline situation if a stop at ORD was all that was needed (after flying from there only from EWR, diversion off normal route, and fuel use associated with approach).

Perhaps related to this situation of shortened runways?

Remember the United 777-200 plane in Denver which had a catastrophic engine failure February 2021? This might be related to subsequent findings with those engines requiring follow on inspections or engine maintenance.

No. There are posts upthread indicating what the source of the issue is. Most if not all aircraft have returned to service following a relatively minor inspection.

No, it was a wing foil issue - not related to engines

I actually suffered the brunt of this yesterday when we had to use the shorter runway and my flight (UA79) couldn't fuel up fully which meant a forced refueling at ORD. Caused a four hour delay and caused hundreds to miss connections (no data, but it just looked like everyone was connecting which makes sense since it's still difficult to get into Japan), including me. That was fun, and super chaotic.

Regarding the Boeing issue, I'm glad they caught it and while the issue may be minor, I have to say it's been a while since I've seen a positive headline about Boeing and not about something that only gives the layperson pause. Not that Airbus is flawless either, but really wishing United's A350 order actually materialized into flying planes.

No inspection is minor.

Looks like the issue was failure to inspect leading edge slats. (no such thing as a "wing foil")

Per the article below:

https://simpleflying.com/united-airl...-cancelations/

"United Airlines grounded a number of aircraft earlier this week after discovering they had not received some of their routine inspections.
...
The FAA reported that United aircraft mechanics had failed to inspect the leading edge slats on many of its 777s. The slats play an essential role in flight, particularly during takeoff and landing. On most airliners, leading edge slats can be adjusted by the pilots to change the camber or shape of the wing to help it produce more lift.
...
The FAA has also begun an investigation into what led to the negligence of the inspections. United told the public on Tuesday that ten of the grounded aircraft have since undergone inspection and will be returned to service."

There is, but it has nothing to do with aviation.

Wing foil surfing!

Time to change the thread title again.
