Dennis Savarese" Subject: Re: Yak-List: 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.

Dennis Savarese" Subject: Re: Yak-List: YAK-52 gear light 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.

You will have to pierce the wires with the ohm meter leads. Getting to the terminal block is a whole lot more difficult.

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 On May 30, 2010, at 8:41 AM, A. Dennis Savarese wrote: Osram OS3899.

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.
