WHAT ON EARTH is Going on with the Boeing 777X?!

-----------------------------------------------------
Boeing just can’t catch a break: its newest and biggest airliner seemed to be progressing nicely this summer, until a NEW problem stopped it in its tracks.
So… what happened, that caused the plane’s certification program to freeze again, how bad is it, and… do we know when this giant will actually start flying with passengers?

It feels less like "Boeing can't catch a break nowadays" more "Boeing have cut too many corners too many times".

[siriusk]

At this point, the new plane uses 100% less fuel. Can't get better than that.

I remember an old documentary on the story of the Boeing 777. When the original 777 was being developed, Boeing engineers were sitting right next to the shop floor and would go and see everything up close and personal and work out any issues, go back and redesign the parts and come back and check the fix. They in fact spent more time on the shop floor than in their offices, getting things done hands on and in real time. The. The MD mismangaers took over and began by taking all the engineers's large offices away, firing or retiring all the senior engineers then outsourcing everything to 3rd parties and hiring rookies to keep the costs down (Penny wise, pound foolish). Damn, I have always hated senior management with a passion, because my first company was one sinking ship too.

I prefer them to find these issues now rather than do it when it is approved to fly passengers.

What's really interesting is that the thrust links were damaged during normal operation. Not after a bird strike or other extreme stress situations.

Cheating, bullshitting, and therefore loosing the trust of the FAA is the gift that keeps on giving for Boeing.

[Prstag]

Also fair play to the FAA for being so stringent and tough with Boeing and not allowing Boeing to rush this plane through

[trghtGuy]

As a mechanical engineer, I imagine it is straightforward to design a thrust link which will hold up. The fact that cracks appeared suggests a few possibilities:
* Problems with the metallurgy of the component (manufacture)
* Incorrect dimensions of the load bearing section (manufacture)
* Unforeseen forces applied to the member (design). Hard to believe you could surprise Boeing here ...
Thankfully this time the probelm was caught before any passengers boarded.

[aegaeon]

Boeing doesn't deserve a break, people died and they tried covering it up blaming the victims.

Mentor, your videos are awesome. But I am a retired Boeing 777 and 747-8F captain. I hold type ratings on 727, 757, 767, 777, 747-400/8F. To correct you, the Boeing 747SP was developed by reducing its length in order to increase range to fly the few customers that wanted a specific range without a refuel stop using the 747 classic. The 747SP was not originally designed for thin low capacity routes

[PavelKostromitinov]

For me personally, the most interesting part was starting around 19:00, when it came around to the aircraft construction.
Please, we want more technical videos!

Cracks in the thrust links? Jesus christ. These are brand-new planes. Cracks already is a sign of just terrible workmanship of the metal.. Incredible.

[Skyer]

@mentour 7:20 "Popular between Airlines, Passengers and Pilots" You can add Maintenance crews to that too.
Sadly I have not worked on one yet (infact I have only touched 737-8 and Max-8) myself but from all my colleagues who have worked on multiple types all had praised the 777 for being very maintenance friendly.

A ‘slight crack’ in a fan blade eventually ripped an engine to shreds in one of your videos. A thrust link failure could tear an engine clean off and take part of the wing with it. Kudos to the inspectors that spotted it 👍

[thomasfholland]

Petter I hope your channels will allow you to get to spend more time with your family. I made that choice here (in Stockholm) because I knew I would never get back the time lost while my children were growing up. For me that’s been the best part of my life so far.

[jeromehugh]

Knowing that the second thrust link held up after the failure of the first one suggests that it is not a static design failure and also it proved the point that its a failsafe design. However having failed this early in its life cycle makes it hard raises a lot of questions over its fatigue sizing.It's possible that flaws were not detected during the manufacturing.

[maladaptedmalarkey]

It is amazing these insane turbofans even work at all. I had the amazing opportunity to tour the GE fan blade assembly plant near San Antonio and it was incredible to see how much engineering goes into just the blades.

"The 737 that I *used to* fly"

;) Welcome to full time content production!

[miscbits]

As a FWIW, the original 777 was offered with folding wingtips - a grand total of zero customers took the option

[walterpleyer]

Making a feel good story about Boeing these days is an ambitious endeavor
