Since someone revivid this very old thread....

Last month out in Big Bear (cold!), we had a re-occurance of this at 1430 hours on the airframe. This time, I just took the cockpit cover panel off and rapped on the motor with the handle of a screwdriver....and it's been working fine again ever since....

If anyone wants replacement parts for an old style flap motor, I have a complete unused 93 one that will appear in the Classified section in the next day.

Unused, zero time but unairworthy as an entire unit due to incorrect factory cross-drilling at the mounting area.

Motor is marked Pittman 9234C120 73633

Except for the mounting boss, all parts should be good replacement parts...

I recently had my 3rd flap failure. Each time they fail after stopping at 1/2 and then going to full position. In the air, they are failed completely. Once on the ground, they work fine.
On this last incident I recalled that each time each time in the past I would start to hear noise in my headset when the flaps were activated. Once the motor was cleaned the noise went away.
This may be unique to my wiring but in my case I hope to have fair warning before the next failure.

I called Usher Precision today and talked to Brad. A replacement motor for my 9A is being shipped and cost $75 (plus shipping). They were easy to deal with, too. I almost bought a second one to have a spare but I'm hopeful I will get the old motor working again - no joy so far.

For anyone else with this problem, I just talked to Dean Trump at Usher Precision Manufacturing. He said that their current motor should be a bolt-on replacement for the older Motion System units. Originally the Precision units had the same problem with grease, but they have since redesigned the motor with a sealed bearing that is intended to keep the grease out. Price of the motor with the worm gear installed is $125, quite a bargain compared to the price of new motor+actuator from Vans. Great customer service, and he mentioned that they've sold quite a few replacement motors.
