Juan is pretty well-positioned to make these videos; he's a veteran Air Force 'Mishap' investigator and instructor, a current 777 pilot, and a licensed Airframe & Powerplant certificate holder.

This is the third in sequence as he notes.

He lost an engine during a night flight from Hawaii to LA, and said the final 2 hours of that flight was the longest five years of his life. Stuck the single-engine landing at LAX, right on the first hashmarks.

I have read that those splayed wingtip pieces are made by Pocock in the Seattle area. Pocock is the Seattle company that built all the beautiful cedar / mahogany rowing / crew shells for the University of Washington and others, which gave way to super lightweight carbon fiber rowing shells that were world class and appeared in the Olympics regularly, which led to being an expert carbon fiber engineering firm.

If you go watch The Boys in the Boat movie, those are Pocock shells that beat the nazis. That boat that those boys rowed to the gold medal is displayed overhead in the U of Washington crew house.

I think they were also worried when the plug popped out, people would read the sign on the engine…..

This is looking bad for Boeing….UA is finding loose bolts on their Max-9s…someone forgot the torque wrench and the Loctite…

From Juan’s video, the plugs get put in at Wichita, but get removed and reinstalled in Renton when the fuse is fitted out for end customer.

Right - the last person who touched it was Boeing Renton.

I don’t get where the seal is. The “sheet metal” skin is flush with the fuselage skin and there has to be a tiny panel gap to fit it.

You don’t have to seal it that tightly. Pressure differential is only 8 psi or so

Bad humor time

Boeing renamed “ Bolting”

We serve hot nuts , make sure they aren’t metal

The last time Boeing made a profit was 2018.
More deep diving with Juan.


Note his correction about the door plug as received from Spirit.
Interesting picture of the wifi installation being done by "Others."
Sounds like the -9s are going to be grounded for a while.

Ah, so Spirit did the final bolting of that door.

I always learn a lot from his pieces.
