DL617 SFO-NRT, operated by a 763, is diverting to SEA according to FlightAware. Map shows it doing a circle off the Washington coast at the moment.

Medical, mechanical, or something else?

I also believe this is one of the SkyTeam livery a/c. I am guessing a mechanical issue.

After the drama that has happened on aircraft in the past couple weeks, I think I'm out of guesses!



If I wanted your opinion, I'd give it to you!

Seems like quick descent from FL to 10. Not rapid but it did not take long.

Based on that information, it would appear that N175DZ is the aircraft in question. According to FlightAware, N175DZ flew ATL-SFO earlier today before this flight.

It is currently working on another loop off of Forks and has already airborne for 3hrs. Presumably it needs to get under MLW, but how long will that take?

Coincidentally, another DL 763 is operating LSF (Fort Benning, GA) - SEA and arriving shortly. If, by a stroke of good fortune, it is a returning military charter for Joint Base Lewis-McChord, DL would have a spare aircraft in exactly the right place.

Interesting...I'll keep an eye on the track and see if I can catch her inbound to SEA. She'll probably fly right over my house!

Could be, but a lot of the JBLM charters fly directly to TCM, not SEA. I was once extremely confused by an NW 742 crossing over BFI and subsequently making a south turn way too late to be going to SEA...only later did I find that it was heading for TCM. The LSF-SEA flight may well be a charter that's being repositioned to pick up these SFO-NRT folks.

No horror stories people...

The captains window has a loud squeal eminating from it.

it says on Flightaware that it's landing shortly, as of posting....anybody at SEA have any idea what's up?

Somehow, I missed it. Weather's pretty cloudy but the ceilings are low enough that I can still see most everything in the pattern from my front porch...probably underestimated the time delay on FlightAware and stepped outside a moment too late. Looks like it's down safely though, sure we'll hear more soon.

Given the decent and the squeal (see above) from the cockpit window, I would "guess" pressurization problems would be a concern. To me, the squeal indicates there was an issue with window sealing system and the pilots diverted just to be safe.

I too wonder if that's the case. The fact that the 763 descended somewhat quickly and stayed at 10k while presumably getting under MLW off of WA supports your theory.

I don't believe that is coincidence. Appears that there was some type of communication between the flight crew of DL 617 and the Dispatcher back at the DL control center in ATL. Perhaps the flight dispatcher recommended the diversion to SEA because he was made aware by others that a spare aircraft was available there as opposed to air returning to SFO with no spare ETOPS aircraft. The time they spent going in circles burning off fuel to get below MLW could have been spent flying directly back to SFO.

It doesn't appear that this charter involved JBLM. The aircraft departed SEA @ 0230PST 3/28 en-route VCV-LSF-SEA. The charter appears to have been for the VCV-LSF and they (DL) just used a 767 that would have RON/RAD in SEA 3/28. You are correct that charters for JBLM do in fact use TCM as opposed to SEA as I have seen flight plans filed for TCM.

That could be, but a fully equipped maintenance base can get a window changed in about an hour. SEA is a major DL maintenance base, so I'd expect them to have the equipment to swap out a window and the airplane was only on the ground for about 2 hours.



If you have never designed an airplane part before, let the real designers do the work!

The LSF-SEA 763 (N183DN) continued on to PEK, so it was not replacing DL617.

Also, N175DZ, which was 617 is now flying to KIX

Can't be. The Mariners arrived into NRT last week. It was all over on the Japan News regarding Ichiro Suzuki playing in his turf. Prior to opening day, the Seattle Mariners played against the Yomiuri Giants.

I thought the 767-300ER has fuel jettison. Why would they be circling for three hours to get down to MLW?
