TLSDriver Posted June 3, 2011 Report Posted June 3, 2011 I have a KFC-150, Aspen and EA-100. On today's trip I noticed that that the flight director was indicating that I needed to turn left. Problem is that the nose started moving to to the right.(The autopilot was on.) I disconnected the autopilot figuring it was just a weird glitch. I hand flew it until I was back on course. I engaged the autopilot again and it rolled to a 40 degree bank until I disconnected it. Just for fun I turned the a\p on again an and it did the same thing. I killed the a\p when I was around 40 degreess of bank. In both cases I went from straight and level to a steep bank in just a few seconds. Any ideas on any troubleshooting that I can do before it goes to an almost certian big bill at the shop. Thanks for any ideas.
thinwing Posted June 9, 2011 Report Posted June 9, 2011 since the flight director is indicating,ie commanding left ,and a/p is rolling right,problem is not in the computer it self,but the roll servo in the right wing...either the servo itself or the wiring is failing...and yes ita a big bill...figure 1800 usd for overhauled servo from midcontinents,...good luck..been there..sinc kp couch

jetdriven Posted June 9, 2011 Report Posted June 9, 2011 dont just throw money at it, replacing parts one at a time until the culprit is found. Use a shop that has the proper repair and service manuals, and the tester box. it generates inputs such as pitch and roll to diagnose.

MattS Posted June 9, 2011 Report Posted June 9, 2011 I would give the folks at Autopilot Central in OK a call. I just used them to fix my KAP 150 with excellent results.
