Pa-31t Question

[Propsfullfwd]

Does anyone know if there is an accumulator on this aircraft for the props, gear or brakes? If there is will you please tell me about the system. And can someone tell me alittle about the fuel system.

Thanks

PA-31T Systems

The PA-31, from what I remember: For the propeller, "A combination of nitrogen or air pressure, a spring, blade counter weights, and governor regulated oil pressure is utilized to change the pitch of the propeller blades. Nitrogen or air pressure is supplied from the precharged propeller chamber." As for the landing gear and brakes, it uses a hydraulic reservoir for the gear with engine driven pumps and a master cylinder for the brakes just like most general aviation aircraft. As for the fuel system, it consists of four fuel cells (40 gal outboard and 56 gal inboard) of which 187.3 is usable. There are two engine driven fuel pumps and two emergency fuel pumps. There are also a couple of annunciator lights that warn of an probable fuel flow interruption. There is also a cross feed system in place as well. I think that's all, if you have any other questions PM me. Also, if there is something here that is incorrect, someone jump in a correct me. As always consult the POH (ok, now i'm sounding like a lawyer). Have fun!

Not quite

I believe the poster was asking about a PA31T. A much different animal than a PA31. It's pressurized and powered by PT-6's. The props are 3 bladed Hartzells, full feathering and reverse. No accumulators. The props are spring and counterweight assisted toward feather and governor oil pressure towards low pitch/reverse. Same props as on a Beech 99. The landing gear operates the same as any PA31. 2 engine driven pumps and a reservoir/powerpack in the nose. The fuel system is different, too, with tip tanks and nacelle tanks. The brakes are standard hydraulic, same as a regular PA31 with no power assist.
It's been a long time so details are sketchy. I worked on one but didn't fly it. Reliability was OK but it definitely had its own personality.

Gotcha, I was thinking PA-31T (turbocharged). Thanks for steering Propsfullfwd in the right direction. Have a good one!
