thanks fr8mech. Is runaway trim possible on non-Boeing aircraft? It seems like on Boeing aircraft, Boeing commercial aircraft, that you have to grab a spinning wheel and that there is a lot of cranking involved in trimming manually. Maybe I am wrong. How about other aircraft? Runaway trim is possib...Jump to post

So, if you look to the left of the spoiler handle of the MD11, you’ll find 2 black and white striped handles. These are commonly referred to as the suitcase handles. Push forward, nose down…pull aft, nose up. The early Douglas aircraft have them also. So do the MD8X aircraft, near as I can tell Forg...Jump to post
And changing wheels without a jack. Not that anyone would ever use disobey an AMM.
It is canted forward, as is just about every other Douglas aircraft I can think of.
I can’t recall why Douglas chose to do it that way.
Fun fact…the center gear on the MD11 is also canted.
I’ve never been a flight attendant nor got a look at their training, but I suspect they do it because they have the opportunity to. The faster they get those loose, unrestrained items out from in front of people, the better. From a security point of view, it keeps them moving around the cabin. Reduc...Jump to post
Your ligaments or cartilage may have issues. It could also be.........arthritis.... Might be worth having a discussion with a MD.

Oh, I’m sure age has something to do with it, but I find it strange that these issues disappear as I continue my exercise and don’t come back again until I’m set to workout again.

If it's edge wear, on one side of the tire (the "shoulder" tread if you will), I'm thinking it's a torque-link shimming problem. This would put the tire out of alignment making it wear with an uneven pattern. An imbalance will usually result in a shimmy of some sort. Assuming that it’s at...Jump to post
After 4'ish years of illness, injury, apathy, imagined time-constraints, etc. I've decided to run & workout again.

Hawk, more info needed.
Is it one position on a specific aircraft?
One position on all aircraft?
Or, just a general question on tire wear?
And, is it really shoulder wear, or is it edge wear?
I read somewhere that after one landing the balance/alignment would be out so no point really. I’ve built up exactly 3 wheel assemblies in my 34 years in maintenance. Two B727-2xx mains and one B757 nose, and that was 33 years ago. We did balance them, but it was crude. There is a dot near the bead...Jump to post
No, not on the big jets. The only thing that is rigged is the steering system, and the wheel assemblies* have nothing to do with that. That’s all in the cabling and the valve. *there is a possibility that a pair of nose tires that are a mismatch in wear…a new tire paired with an old, almost worn to ...Jump to post
I wonder if Kapton insulted wiring played any part in the loss of TWA Flight 800. Not sure what kind of wiring was used in the wing tanks of those older Boeing 747's.

Normal aircraft vibrations can cause damage to any wire. Wire will rub against other wires, clamps, lacing or structure.

But from a logical perspective, if you don't know that someone is dead, and you decide to shoot that person multiple times, I think we can draw a reasonable conclusion that you are trying to make sure that person is dead. If you thought the guy was alive, then you are clearly trying to kill him. If...Jump to post
Could analog television stations be received onboard a private aircraft with one of these antennas? If I remember my schooling, the VHF TV band was pretty low on the VHF spectrum. So, maybe?

Ok, you’re the prosecutor. Prove that the driver did not know the guy was dead. That seems fairly simple. Did he get out of the car and check for vitals? If not, then he doesn't know the guy is dead.

Can a pressure switch with a valve device, or pressure control system that can control pneumatic pressure and prevent airflow noise? These things are already installed in the systems.

Change in pneumatic pressure is a probable cause. When the engines are pulled back to flight idle, the high stage valves open to supply the needed air to maintain the cabin. What you’re feeling/hearing is probably just the increase in pressure until the pack flow valves catch-up. I could be wrong…ne...Jump to post

You can't have "attempted murder" for someone who is already dead. If you do not know if the other guy’s death, then surely it is attempted murder? It’s about the attempt, not the result.

My take on this: Stand your ground: it certainly started as a stand you ground situation. Assuming the driver wasn’t committing a crime while attempting to use the ATM, he had no duty to retreat or flee, and had every right to defend himself.

There was one case where a bleed air duct detached during a severe turbulence encounter.

Those are VHF antennas. The Global only has 2 VHF systems installed, unless there’s a third antenna obscured by the #3 engine. The Pan Am has 3 systems installed. When was the third installed?

Without looking at the book, I'm pretty sure that Boeing considers wheel wells as enclosed spaces for classifying fuel leaks, so welding in there would be a no-no.
Normally, if something needs to be welded, it is removed from the aircraft.
