UPS MD-11 crash at SDF

Boris Badenov said:
Ran across a parked MD tonight (er, last night, whatever) in SJU. It was powered up and there were ladders all over the place, so El Capitan ventured over and button-holed a line mechanic. Said line mechanic was just doing routine mx, but believed that they'd be back flying in the May/June area. (He also said that there was not as yet any directive on how to comply with the AD, so). Worth what you paid for it, but interesting.

What do you mean May/June? They’re going to be flying intra Europe in February 😏.

Every MX person that talked about the MD last week mentioned they were being buttoned up for long term storage so the airplane being down that long makes sense. In reality who knows. I just fly my schedule and do what I have to if the schedule gets too crazy.

You know, even for official record keeping purposes, I still think the guy who died from his burn injuries should count as a UPS crash fatality. He’d be alive if it wasn’t for his burns and injuries from the crash. And he was in the hospital the entire time. Sure, legality wise the family can sue, get money, etc.

But there’s something to say about the official count of death for the accident versus not.

Any investigation, repair resolution, or potential return to service updates?

Nope! All the MD’s I’ve seen across the system have been sealed up for long term storage. I think the company figured out it’s going to be longer than just a few weeks.
 
They were doing de-icing on a FedEx MD11 at EWR on New Years Day, kind of surprising. Maybe for training?

The UPS MD11 at MSP is all sealed up COVID style.

Apparently they de iced ours in ORD as well when they had snow at the beginning or middle of December. Something with a bigger brain and more MX knowledge might have a why.

Either way I think it’s going be a while and a few unsavory things might found before we hear anything worth talking about.

The NTSB just posted an update here (PDF): https://www.ntsb.gov/investigations/Documents/DCA26MA024 Investigative Update.pdf


The last page, which shows selected FDR parameters, seems to indicate to my untrained eye that shortly after engine 1 departed the aircraft, engine 2 began to stall and / or surge, and then shortly thereafter began to spool down. You can see the engine 2 N1 and N2 speeds start to rapidly degrade at the exact same time aircraft roll angle begins to increase commensurately. Absolutely horrible.
 
Boeing told operators in 2011 there could be a problem with the part that cracked after several they found the problem on four failures, but told operators it wasn't a safety issue.

I wonder how much this increases Boeing's liability.

Cracked part in fatal UPS crash flagged in 2011 by Boeing

A cracked part found on a UPS MD-11 cargo jet that crashed in November in Kentucky was flagged in a Boeing service letter more than a decade earlier, the National Transportation Safety Board said on Wednesday.

Liability?
That's an ABSOLUTE "YES"
Any jury in the country will crucify them.
 
Wellllll we don’t yet know if the bearing race failure was causal to the lug failure. Maybe it was, maybe it wasn’t. If it was, that’s a pretty big oversight in their analysis of the original bearing problem.

It looks like engine two started to stabilize right at the end. They almost had it.

To be clear, I think it’s entirely possible that the bearing failure caused the lug failure. I’d say it’s even likely, it seems like a large coincidence for the failed bearing to just happen to be in the same lug that failed. It’s not hard to imagine a scenario where a broken bearing race and movement of parts not intended to move would initiate fatigue cracking in the lug. We just won’t know until the metallurgy geeks do their thing
