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

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

2W vs. 3W is no problem. I do not know of a US equivalent for the
annunciator panel lamps.
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.

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?

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?.

I know Dennis is answering your questions, and his answers are always solid
.-

But... what might be interesting is to put power on the aircraft and then h
ave someone click the up and lock switch and see if the up and locked light
comes on, and the Hobbs meter starts running.- If it does.. that kinda m
eans there might be nothing wrong with the switch at all, and either it is
out of adjustment, or... the gear is actually not going all the way up.-
In other words, it might actually be telling you the truth.- The switch h
as nothing at all to do with the gear going up or down, so there is no safe
ty risk I can think of doing that.-

Not likely, but always a remote possibility.
