The Boeing Co.’s four-engine Dreamlifter, a heavily modified 747-400 cargo jet that shuttles parts for the company’s 787 Dreamliner around the world, is in the process of having its Pratt & Whitney 4062 engines upgraded to the modernized version of the same engines.
The upgraded 4062 engines are the same as those used on the twin-engine Boeing (NYSE: BA) KC-46 Pegasus tanker.

Makes sense. Boeing seems to be getting 10-12 hours/day utilization out of them, quite surprising for such a specialized aircraft. That's enough to spend some money to save fuel.

The PiP is good for a 2-3% reduction in fuel burn and is available on all PW4062 family engines.

So this will make 3 789's HU will have taken delivery off in the past 2 days

The sale was reported a few months ago, but so far the shell is still at Paine Field. It's been moved around a few times to various storage spots.
I doubt Boeing would want such a visible reminder of the mess that was early 787 production on exhibit. Complete early build 787s are one thing, but a frame in LN5's condition (partially dismantled in preparation for rework, then scavenged for parts) would send a very different message. I'm sure it will be scrapped eventually.
Yunus747 wrote:But if any museum would really have interest in that frame and would involve itselve on getting it, maybe they consider not to scrap it. It may not be that they do not want it to be displayed by any means. I do not not what the process was with the two 788s that are in a Museum, if Boeing came and said 'hey, do you want to show them', or if the museums made themselves strong for them getting the planes.

It's in their new pavilion and is opened up so you can walk thru and even check out the flight deck
( behind plexiglass of course)

Do they have a full interior installed on it? I haven't been to MOF in a couple years and this bird wasn't there last time I went. I was fortunate enough to go on board LN3 when it was doing it's "world tour" prior to the 787's EIS, but there were only a few rows of seats in each class set up to demo what it would look like. Did get to play with the mood lighting and sit in the captain's seat though, so that was a good trade off

Would it not be a good idea for Boeing to keep LN4 for various testing? They have sold every other prototype (787-10, 737-8 & 737-9) besides the second 787-10 prototype although I would presume that they will sell that one aswell.

Is this still planned, has it happened already or has sb. new pictures of it? It would be much nicer to see it in a Museum or something, especially when you get an 'inside look' because some parts are missing.

Eventually we have to learn how to scrap a mostly CFRP aircraft...LN5 is probably the guinea pig. I'm sure how it is best scrapped will be well documented.

since design testing is better accomplished on a current in production aircraft, and there is no need to incorporate previous production enhancements, Boeing typically "leases" an aircraft from an obliging customer for the tests.

I believe LN5 has been written off and was removed from the inventory. Boeing took a one off charge on this aircraft last year.
