Re: A321 Tire Replacement

Actually, you won’t find tire replacement criteria in the AMM, but rather in the individual airlines Procedures Manual.

Re: A321 Tire Replacement

As was stated earlier, if the tire was found flat on arrival, both the flat tire and the opposite tire have to be replaced. A321 wheels take much longer to change due to brake fans (if equipped). Plus, if the contract maintenance personnel have little experience with these wheels, you are looking at...

You must have flown on a 707-331. They were finally retired in 1979. This was probably planned a long time and there was no point painting them in the new livery unless necessary.

Re: Question For the Mechanics: Which Commercial Aircraft Have Been Easiest and Most Difficult For You to Work On?

This question is more easily answered with regards to engines. For me, no question, the easiest engine is the RR Trent 892. Most things are mounted on the fan case, which gives much easier access. Fuel control changes are a breeze. It’s not always RR. PW2000s had the edge over the RR211. Late model ...

Re: Is it possible to access the cargo compartment from the passenger compartment?

On a 777, you can access the forward cargo from the E&E compartment, which itself is accessed from a hatch in the floor in the first class galley. To open that hatch you need to be able to unlock it. The 787 has no such access.

The thing you must remember, aircraft brakes are on landing gear that retracts into limited space. That motion limits what you can do with aircraft brakes. Generators, motors, batteries and the associated wiring and control systems would make this all impractical.
