I have a 54 E35. For the last 4 to 5 flights, during pre-flights, I have noticed
my main gear doors did not close completely sometimes. One time, they were
open about 1/2 inch. But they closed completely after my last flight last
weekend. What are they trying to tell me? Can I safely operate my Bonanza
until next annual which is Jan 07?

Hi Robin-
Hopefully the more experienced folks will chime in. But let me get the
ball rolling.
Sounds like you may have a tired motor.
On the ground, you should be able to turn the handle 1/8 to 1/4 turn
before it hits the stop. If you can turn it more than that, it is
stopping prematurely and that explains why the inner doors aren't closed
all the way.
In flight, you can do the same test with the gear up. Just turn the
opposite direction. The same 1/8 to 1/4 turn applies.
Verify that 1/8 to 1/4 is the proper tolerance for your airplane. I
believe that applies to all the 12V airplanes (except for maybe the
straight-35's) but double check.
You might also time the extension and retraction process; for the 12V
airplanes I think normal is 10 sec or so. Much beyond that is also an
indication of a tired motor.
I don't have any good advice about flying the plane with a tired motor,
if in fact that is what it turns out to be. It would make me nervous,
but I'm paranoid.
Good shops for overhauling the motor are Aircraft Systems in Rockford,
ILL and Cruiseair in Ramona, CA.
Again, hopefully folks that have more experience than I will chime in.

For some reason the landing gear motor is shutting off too soon. I would
put it on jacks and get it checkout before anymore flights. Something is
out of rig!

I recently installed the Cleveland brake kit 199-50 which uses the 6.5x8 rims and
and Superhawks tires. I find the outside edge of the calipers are just rubbing
the main gear doors. I checked and the tires are up tight when retracted.
Any ideas?
Also, I have a Curtis drain valve that needs changing on the left main tank. This
is the hose clamp type. It looks like I have to pull the bladder to change
it. Am I right?
thanks for the help, rob.

Don't know about the rubbing but the Curtis drain valve can be replaced with
out removing the tank. Two people work best one to stick his finger over the
hole to stop the fuel flow and the other to reinstall the valve. A little
messy but gets the job done. Take proper precautions with the fuel. Use a
drip pan and put your cigars out!

Robin,
It may not be the motor at all . Have you checked the rods under the
front seats that connect there. You can have as much as 3/4 inch of play on
the closing if they are not adjusted and tightened properly.

Robin,
There is lots of info on the American Bonanza site on this issue. I had the
same problem and it was a tired gear motor. There should never be a reason
to adjust the linkage on a Bonanza. If the parts are worn in the linkage
replace them, but I believe 99% of the time it's a tired gear motor. I
wouldn't wait to replace it. While we can definitely lower the gear
manually, its not much fun to do this in IMC!

I had the same thing, it just got inconsistent and then the gear started taking
longer to extend.Finally one
day, select gear down, and nothing. That got my attention! Uneventful manual extension,
and later on the jacks
the gear worked ok, but slow. Pulled the motor and it was full of carbon dust.
Rebuilt-end of problem; retract
speed much better and trouble free ops since then.
Good luck

Hi Bob-
I think timing the gear extension/retraction process from time to time is a
good diagnostic tool. I try to do it before and after our annual
inspections, and again at about the midway point between annuals.
Ours has consistently been between about 9.5 seconds (12 V Debbie). I try
to check the free-play in the transmission at the same time.
Hopefully that will help identify a motor or rigging issue before it becomes
a problem. But so far, nothing has changed, which is good news!
