| B727 @ National Museum of Commercial Aviation |
The National Museum of Commercial Aviation in Atlanta currently has three aircraft: a FedEx Boeing 727, a FedEx Fokker F-27 and an AirTran DC-9-50. Today we performed some hydraulic service on my 2nd favorite tri-jet ... the B727; number one of course being the L-1011. Even with the aircraft sitting still there are a number of service tasks that have to be performed from time to time because fluids, such as hydraulic fluid, that are needed to keep basic operation of the aircraft stairs (aka. air stairs) will slowly evaporate and bleed out of the systems.
The hydraulic service access for the B727 is right behind the left main-gear wheel well, as indicated in the picture above. If you are not too tall you can actually quite comfortably reach everything in the service center while standing up:

The fluid that we used to replenish the hydraulics with is the lovely Skydrol 500B. I say lovely because it is pretty nasty stuff when you get in contact with it.

Even without power on the aircraft the hydraulic system can be replenished with a hand-pump. So, all in all it didn't take that long to put about a gallon of Skydrol 500B into the B727.
