KAP 150 Auto Pilot Pitch Servo Repair

[M20JFlyer]

 

I NEED HELP

Does any one know if the King 200 series and the newer King 140 series of Bendix/King..now Honeywell autopilots, use a Pittman Motor in the Servos.

If you have had recent experience with needing service on a King/Bendix AP SERVO  please PM me at the e-addres at the bottom of this message.

The King 100 series does indeed use Pittman for the servo drive motor.This week I made contact with several BK service centers.         All had less than happy news to share... if indeed the servo motor is not up to spec. Not up  to spec does not mean your motor has quit but that the service center determined the servo's motor will not perform to standards. 

Honeywell anticipates that over 10K perhaps as many as 20K BK, Allied Signal and Honeywell units averaging three servo's per unit are in use. ( this number is not a verified number)  

If you are flying an airplane with a BK autopilot and a servo motor were to become in-op your AP will quit. 

Has anyone recently experienced  a KAP 100 series or King 200 series autopilot repair when the service required a servo motor repair? If you can share your experience with MooneySpace or PM me it would be appreciated.
