Hey guys,
Just completed the annual and during the maintenance run up we discovered that
the stab trim does not work. Worked great last time I used it, but no so much
anymore. It refuses to move what so ever.
Here is what we know so far;
The motor works. We connected it directly to 24v power and it works well in both
directions.
We think the problem may be with the control box just above the motor (the one
containing the 4 contact/stop switches) or with the relays in the aft fuselage.
Anyone ever saw this before? If so your ideas would be greatly appreciated.
Cheers,
DF

Could be some switch near and connected to the flaps.

Thanks.
I will look it up.
I did blow the flaps down (I had to service the accumulator any way) to make sure
the fact that the flaps were up didn't affect the stab trip, but still no change.
I will look at the switches. I would assume it is a stop switch in the
up position?

Normally the cannon plug that was removed
When the tail was removed. Clean the plug and pins.

Ok, we'll look at it, but we do have 22volts at the connector next to the motor.
Is there a different pin for the power than the signal?

Micro switch is stuck. Remove top wing strap and use long screw driver to actuate
micro switches.
I cant remember which wing??

remember the flaps need to be out of the UP position. So if the trim motor doesnt
get that signal, it wont trim. After sitting for a long while, the micro switches
get stuck in their last position.
My suggestion is to jack the airplane up remove both wings and the entire tail
section, replace all microswitches, replace both canopies so you can see if the
trim motor works, order pizza for all of us and
buy a cessna 152. Now if that doesnt work, just use the screw driver on the microswitch.
It will be the sw that shows the flaps full up.
