Guys thanks for all the advice I am planning to put it in the shop this week and have an expert walk my mechanic through the troubleshooting.

A point of clarification I still have my nise gear doors installed but my main gear doors are gone.

Also I flew Saturday about 5 days since the last flight and the gear worked fine. Then when I was back taxing at my destination airport over rough pavement my green light went off and I got a gear warning horn(throttle was under the limit) I pumped the handle one time and she was back to normal. I think this is telling me one of my limit switches needs adjustment.

Thouhts I could pass onto my A and P are welcome.

I agree. If it my 210 after all the trial and error I definitely would contact Paul New.
"Paul New from Tennesee Aicraft Service inc in Jackson who knows everithing about Cessna 210."

I realize it is a competitive organization but no one should mind if you are actually finding a solution. Paul advises through Cessna Pilot Association and will advise directly as well.

I know nothing bit the other reference.

Keep playing with the gear problem and sooner or later you will have a failure and major damage.

Hi Mike;
Question--have the main and nose gear doors been removed from your 210?

I am not against that mod but I always tell owners to not mess with the nose gear door system.

I'm convinced that one of the gear down switches or the wiring to one (or more) of the gear down switches is either sticky--which would explain the sometimes yes/sometimes no operation of the light/gear.

Or the switch is not adjusted per the manual.

It's also possible that the length of the nose gear actuating piston rod is not quite long enough. It needs to be long enough to get the gear completely up against the up stop. While still being short enough to pull the nose gear into a completely down position before the piston runs out of travel in the actuator body.

When you pump the hand pump that pushed the gear up enough to close the uplock circuit, which then allows you to move the gear handle to the down position.

Thoroughly inspect and clean the landing gear switches.

Let me know what you find.

Steve

in the 210M the gear lights desappear when the gear is in transit. If the gear is out and locked the green light is on, if the gear is up and locked the amber light is on (during all the flight).
The fact that all the lighs disappear when you lift the nose from the ground seems that some gremlin wakes up when the squat switch close the circuit.

The best ghosbusters I know ,( they both helped me to debug 210 problems with success inspite we were at the opposite shores of the ocean.I am in Italy) are:

Rick Cox at who is specialized in hydraulic gear systems

Paolo thanks for the reply. I have had a few people say the same thing but it does not explain why the green light shuts off when I break ground as I don’t think the light circuit runs through the green and amber lights.

It seems to me that the problem could be in the squat switch. It is a switch in the nose gear compass well visible when the gear is on the ground.Its function is to avoid that the gear retracts when on the ground. When in flight the extended compass squeezes the switch which closes a circuit and allows the gear to operate.
