| Subject: | Re: flap actuator |
Yes Steve, the shuttle valves are the same on the undercarriage
actuators. You said "disintegrated". Are you speaking of the hard,
rubber ball inside the shuttle valve or something else? I personally
have never seen the hard, rubber ball inside a shuttle valve
disintegrated. But I have not disassembled as many shuttle valves as
Jill has either.

<completeairnt@bigpond.com>
was recently flying our 52 and the flap actuator jammed in the up
position.Returned to the airport and removed the actuator,disassembled
the item and found both of the shuttle valves had disintegrated.has
anybody seen this before ,is it from contamination and is the same type
of shuttle valves in the undercarriage actuators?.

Have you adjusted the arm that engages the button on the micro switch as
Mark suggested? What about putting an ohm meter on the micro switch to
verify operation? There is no common fuse because if there was and the
fuse was blown, all of the gear lights would be out.

The lamp for the gear up is fine (using test button), and the
microswitch on the uplock does click when you trip it or press it. The
down and locked light is not an issue (goes out when retracted. Are all
gear lights on the same fuse?

Push the microswitch button itself. It should click very
distinctly when you depress the button. Does the green light go out
when you retract the gear? Does the lamp come on when you press the
press to lamp test button. Put an ohm meter on the microswitch if you
suspect it to be bad. You will have to pierce the wires with the ohm
meter leads. Getting to the terminal block is a whole lot more
difficult.

Subject: Re: Yak-List: YAK-52 gear light
Hey, Dennis / Doc... I notice that lamp I took out was 2W (the
Osram is 3W)... assuming that's a trivial difference. Also, is that the
same lamp as used in the annunciator panel? If not, do you know the lamp
part number equivilent for those?
Lastly, my Hobbs is on the left main gear switch, which is not
working... thought it was the switch adjustment, but it seems to be
clicking when the up lock is tripped. So, I was guessing it's the switch
(didn't put a meter on it yet), but I also wonder if the Hobbs was
drawing too much current and tripped a fuse. I don't suppose the three
gear indicator circuits are fused separately?
Thanks again. -Eric

Does anyone have the part number for the YAK-52 gear light? I
seem to
remember it being an Osram item.

I thought the switch was depressed with the gear extended. With the
common (to all gear lights) circuit you described, it's either
adjustment or switch, and since it seems to have clicked on extension,
I'm guessing switch. I'll put a meter on it.
Thanks.

Just got my overhauled CJ airspeed indicators back from World Wide Warbirds. Cleaned,
calibrated, painted, and re-screened for $175. I think they look fantastic!
Thanks Barry!
