Help! Any Good General Tips On 747-400F's

Thu Oct 26, 2006 11:47 am

Hey. I start a job working 747-400F (80 %), DC-10, MD-11, 757 and an A330's. I was wondering if anyone has some good little tricks on the 747-400F since I will be on my own and going to a 747 from CRJ's and ERJ's.

Buy bigger tools. Your 1/4" drive will be a little small.

Always make sure that the push button on the steering bypass "pip" pin pops out when you insert the pin. Pull down hard on the bypass "pip" pin to ensure that the spring loaded locking balls will hold the pin in place.

Often, the locking mechanism on the bypass "pip" becomes sticky and the locking balls will not hold the pin in place. When you insert the pin into the steering bypass hole, there may be enough friction to hold it in place, but one you start pushing back, movement of the steering summing lever can reduce the friction on the pin and allow it to drop. Expensive crunching noises may quickly follow.



When installing the tow bar on a 747, give it a hard tug to make sure it is engaged. The 747 uses two vertically moving pins to engage with the tow fitting on the NLG. Some tow bar designs make it hard to see if these pins have gone through the holes on the tow fitting.

Always try and access the Main Equipment Centre (MEC) from the external hatch. There is a panel on the main-deck to allow you to climb down, but during loading / unloading operations, freight pallets can move across this opening. There is a safety switch on the main-deck access panel to cut power to the loading system when the panel is removed, but you still don't want to risk having your head chopped off by a pallet.

Hi RJWrench85, Buzz here. Jet Mech in Aussie has a couple valid points. One that I'd add is to learn how to use the CMC to BITE test the systems.

If you can get any training in the Boeing systems, take it. Boeing hooks up things a bit differently than the RJ's. When you understand the systems you can troubleshoot better.

And don't lose your 1/4 drive sockets... despite what EMBQA says there's still a lot of small hardware holding things down (for access) on the Lump. Boeing does it that way.

Engines don't give us much problem, high oil consumption once in a while or maybe one ignition inop, or anti ice valve.

g'day

Your 5/16 and 3/8 sockets will still get a workout  Smile

Just watching them on through trips (Fuel Load, Oil Checks, God forbid something breaks I will have to do some work)

I got to get shown a 747-200 (Man they have enough analog gauges to kill somebody) and it had a quick turn so I had to put the brake fans up to the mains.

Thanks for the tips and I am glad I kept my 1/2" drives nice and shined up!

Line Maintenance is a Challenge.Not much you can do if a Snag requiring Component replacement arises unless the Spares arrive.
But it a good thing to have to tackle snags in Line.It helps one work,think & troubleshoot against time.

Just remember one thing I once heard. When things get complicated, things go wrong. And the complicated things are often the most expensive things to fix.

Have fun.
