During my last before-takeoff check I noticed the Altrak was not working. To check, I engage it, then gently move the stick for/aft a little to be sure I can override the hold. This time there was no resistance.
The brass screw on the servo arm was sheared. I'm assuming it is designed to do so in case of servo runaway.
Background:
Our last flight/s were to CO from CA. One the way to CO we noticed some squeaking sounds coming from the rear. I assumed were able to hear the canopy squeaking or something because the engine was at low power levels at high altitude (15,500).
Same thing happened on the way home, at first. Then I never noticed it anymore, but the altitude hold virtually quit working.
The light would flash when it got out of altitude range, but would not bring it back in.
So, today I'm planning to remove the Altrak box and the servo motor to send them back to Trutrak for repair. Probably only one has a problem, but I'm not sure which.
Any additional insight would be appreciated.
