Spotted: Four AA 777s in HKG parked in HK maintenance hanger today.

Anyone know what's going on?

They are receiving maintenance

Interesting

Given HK's daily DFW flight, I thought one frame is enough. Maybe the rest came from PEK and PVG, perhaps. But it is a heck of a lot of maintenance at HAECO in one go.

Receiving the new 2 class interior, perhaps?

As indicated by the 772 CIP thread, three of them, if not all of them, are undergoing C-Checks and the CIP.

Actually, exactly one is receiving CIP at present.

Whoops, my mistake. Thanks JonNYC

AA previously performed 777 heavy checks at its former in-house maintenance base at Alliance airport in Fort Worth (AFW). During its bankruptcy, it closed that base and outsourced the heavy maintenance of its 777 fleet to HAECO. AA has 47 772s and as they're due for heavy checks every 18-24 months, I'm not sure that I agree that seeing four of them in the hangar is more than necessary.

Not only has AA outsourced the heavy C checks, but the cabin reconfiguration has also been outsourced to HAECO, so all 47 of them will need to pass thru HKG for heavy checks and for the cabin refresh over the next couple of years. Heavy C checks can take 3-4 weeks, so seeing more than one at a time at the hangar doesn't seem unreasonable to me.

Don't blame ya, that thread is getting a lot of speculative noise and that's making it quite confusing to follow.

If 4 were spotted, it's the one almost certainly being CIP'd (N787AL), N788AN which is CIP'd already but has been out of service for a few weeks and the 2 others, unknown what they're in for, all the guessing notwithstanding.

As we know, the thread for this discussion is here:
