What do you think happened to Alaska 1282 losing the plug? NTSB also reported the depressurization lights had come on 3 times prior to the accident. How can you all check that?

[@StigAviation]

I believe the news is already out and it was a case of loose bolts that hold the plug. As for pressure checks… we can perform pressurization on the ground. Basically seal the aircraft and pump it up using the air conditioning system

[@stevec7793]

Im just glad no one was seriously injured or worse. Shouldnt the pilots have written up the indicator lights coming on especially since it happened twice while the aircraft was on the ground? Would that be a reason to ground the plane from service until the issue was corrected?

[@StigAviation]

@@stevec7793 in my opinion yes, the Pilot should’ve written it up, or maybe they did and whatever procedure they performed, corrected that issue at the time. Once again, I don’t know all the details of what transpired with that aircraft. So it would be purely speculation, and, I cannot speak on something I don’t know, that would be unprofessional of me.

I worked in emergency services in Upstate SC. Lockheed has a facility in our area (now they build the F-16 there). At that time, they had the repair contract on all the Air Force KC10 tankers. They allowed us to practice confined space rescue in the wing structures of these aircraft. Despite their size, it's still difficult to move around when you're kitted out with respirator and supplied air lines.

[@StigAviation]

Most definitely very difficult, here’s the interesting part, getting inside the tank is actually not that hard, moving inside and maneuvering through the baffles is a nightmare, especially when you start getting to the tips of the wings. And the most difficult part is usually getting out of the tank.

[@kentuckyken6479]

Hey Stig, I found the ratcheting open ending wrenches you showed on your tool video. Had to enlarge a frame of the video to read “Alden” on the wrench. Found out they were originally called Alden wrenches (named for their inventor) but that company is no longer in business. After some patent fights, I believe Chicago Brand (Medford OR) bought them out and currently make them. They are still polished stainless steel, so no chrome chips to worry about as you mentioned, but are not quite the same quality as the old Alden ones. I bought a set as soon as I saw your video. Thanks for making me aware of them. They are perfect for tight spaces and so much easier to use since you don’t have to take them off and on the nut or bolt. Just Google Alden wrenches. Your videos are highly informative and your attitude is infectious. Keep up the good work keeping us all safely flying.

Hi stig what is the minimum quantity of fuel that can be jettisoned? Is it possible to jettison fuel if remaining fuel in the center tank is 200 kg during flight? Center fuel tank pump Low pressure light illuminates if there is low fuel in the center fuel tank.

I’ll be honest with you I can’t remember what’s the minimum amount. I would have to look that up. As for the center tank, the fuel from the center will be pumped into the wings regardless of jettisoning from the wings.

So what you’re saying is that those wings are completely filled with gas like a bottle of water?

Yup. 👍

[@buckerjungmann]

A 777 holds around 45,000 gallons total. It’s got to go somewhere, and the wings are hollow anyway. If I remember correctly, each wing holds about 13,500 gallons. The remainder is in a center tank in the fuselage, which is burned before the wing fuel for structural considerations. I rarely flew one with full fuel though. If the trip doesn’t require full fuel tanks, it’s not carried as it takes fuel to haul it. The few times I had the tanks completely full on a 777-300 (313,000 pounds or something over 45,000 gallons) I was flying from DFW to Hong Kong… 16+ hrs. An amazing airplane. Then along came the 787.

There's so much to be an expert on - do maintenance engineers specialise, or are you expected to know how to maintain everything?

[@StigAviation]

It’s not about knowing how to repair everything it’s about more of basic knowledge and knowing how to interpret manuals. The manuals have all the technical data that we follow. Also, it helps that we know how to use tooling properly.

Stig, would you please show us what component failed in the Alaska Airlines 737 and caused the loss of pressurization? Thanks.

[@StigAviation]

My friend it’s already out in the news. The bolts that hold the plug. I don’t need to make a video or explain it when it’s already done.

[@zlee11]

@@StigAviation what plug are they talking about?

[@StigAviation]

The things that actually blew out is a dummy plug. They have an option to have a door there, depending on seat configuration.
