There is a constant leak I can hear from it.
We serviced and cleaned at annual and still there.
Since the rear seat will only be used by passengers and not an instructor, I prefer to by pass it.

How do I do that?

Have you seen this diagram.  It is on Doug's website and layout the air system very nicely.

First before you go to the trouble it would be wise to make certain that the air noise is not coming from air leaking past the seals in your flap actuator.

Hello-

Remove flap handle noting the neutral “in” line (if in doubt, turn on your air and it will be the lone that has air coming from it). On the bench remove one of the Chinese/Russian fittings from flap valve and cap the NPT end with a brass female 1/8” NPT cap (see link); take this capped fitting back to the rear cockpit. Take old “B”nut from the neutral line and screw it back on the nippled end over the flare. Done. Line is now isolated and out of the flap system. Other two lines (up and down) are static now and serve no purpose. Cap link below but can buy from many places like Ace/eBay etc.

It may not be the flap handle. It also could be the flap actuator too, leaking by the seals. If you put the rear flap handle in neutral and the front flap handle in the UP position, do you hear air leaking from the front flap handle?

No Dennis , I cannot hear any air coming out of the front flap handle in the up position.

You said: "Since the rear seat will only be used by passengers and not an instructor, I prefer to by pass it. How do I do that?"

There are restrictors in the pneumatic lines going to the main and nose gear actuators. Doug has these restrictors that are undrilled. Initially, I used these undrilled restrictors on the 3 airlines going to the rear seat flap handle to bypass the rear seat flap valve. I later used these restrictors on 3 nipples to block the airlines, and sent the failed flap valve to Gill/M14-p to polish/overhaul so I have a spar flap/gear valve.

There are also two diverter valves at the rear gear selector that you must consider as well when bypassing the rear selector. Notice them on the schematic that Mark Pennington sent you.

Very simple. Disconnect the center line going into the flap control valve in the rear cockpit. Screw the "B" nut on that line with a plug. This is the air line INTO the valve. Once its plugged that valve is inop. You can also remove the handle witch wound have no effect anyway. Jim "Pappy" Goolsby
