Subject: | Testing Fuel Shutoff Valve |
The question originally was, do you know how to test the fuel shut off to see if
it really is shutting off the fuel without having to run the engine to find
out?
As noted by others, testing the fuel shutoff with a running engine takes a very
long time.
I would think you would open the system after the fuel strainer and then operate
the wobble pump to apply fuel pressure to the system.

Subject: | Removing GIB Controls |
I've been contemplating the pro's and con's of Rear Cockpit controls for
Gear, Flaps, Mags and Emergency Blowdown.
For me personally, 90% of the time the rear seat is empty, 90% of the time
the rear seat is occupied it's with a non-pilot passenger. I don't ever
expect to be giving instruction from the rear seat or allowing anyone else
to use my plane for such purposes. When I consider the extra points of
failure in the rear seat, the complexity it adds to the air circuits, and
the very real possibility of inadvertent manipulation of a gear, flap or
mag switch, plus the additional sources of air leaks, the argument for
removal is strong.
Other than re-sale or dual instruction considerations, I can't see how the
redundancy benefit (albeit only when theres someone back there) outweighs
what I outlined above.
I know some folks have just removed the handles, from the Valves, but I'm
talking about complete removal to simplify the air system and make it more
reliable.
The plumbing job is rather easy. And reversing it is just as easy.
Thoughts????

Rags stuffed in the intake works to. Watch that big fan on the nose though. I

Had to do that once when one of the P leads became disconnected and the fuel
cut off was not completely closing.

Subject: | Re: Removing GIB Controls |
Gear, Flaps, Simply remove the handles. During annual condition
inspections you can put the handles on for the testing, than off again.
Mags. You can drill a safety wire hole though the flat of the switch and
safety it to one of the mounting screws. You can use copper wire IF you
don't want to give up ALL the possibility of turning the engine off.
Remember to safety wire or block the selector switch above it to front coc
kpit
control.
Emergency Blowdown. Again simply take off the handle or heavy safety wire
it.
One thing I would do which is a little more work but simple. Re run a
line from the QS1 valve direct to the QS2 valve. This bypasses the brake
cutout valve on the rear control stick. Eliminates in advertent use and
removes a number failure points in the air systems.

Jon,
I wasn't referring to flight controls, just gear flaps.

I've been contemplating the pro's and con's of Rear Cockpit controls for
Gear, Flaps, Mags and Emergency Blowdown.
For me personally, 90% of the time the rear seat is empty, 90% of the tim

the rear seat is occupied it's with a non-pilot passenger. I don't ever
expect to be giving instruction from the rear seat or allowing anyone else
to
use my plane for such purposes. When I consider the extra points of
failure in the rear seat, the complexity it adds to the air circuits, and
the
very real possibility of inadvertent manipulation of a gear, flap or mag
switch, plus the additional sources of air leaks, the argument for removal
is
strong.
Other than re-sale or dual instruction considerations, I can't see how th
e
redundancy benefit (albeit only when theres someone back there) outweighs
what I outlined above.
I know some folks have just removed the handles, from the Valves, but I'm
talking about complete removal to simplify the air system and make it mor
e
reliable.
The plumbing job is rather easy. And reversing it is just as easy.
Thoughts????

Has anyone been able to use the Chinese B-Nuts on Flexible hose like
Aeroquip 666? I'd like to know what mandrels, etc I would need to make this
work.
Thanks
Ernie

Subject: | Re: Aeroquip Hose |
Use Aeroquip 303 hose with AN491-x fitting. Throw away the AN nut from the 4
91-x and use the metric B-nut on the 491-x fitting. Use the appropriate size
mandril for the 491-x fitting available from Spruce if you don't already ha
ve them.
