Finally had a smooth autopilot calibration on a King Air 200

We had this King Air 200 in the hangar in Nashville that was giving us fits for like two weeks. Every time we ran the pitch axis calibration, it would throw a fail code around step 4. The senior guys were pointing fingers at the roll servo, the pitch servo, even the AHRS. I was about to pull my hair out. Then on a whim I checked the wiring connector behind the panel and found a pin that was pushed back just a hair. Crimped a new one on and the whole thing went through perfect in one pass. Felt good to get that bird back in the air after 14 days of headaches. Has anyone else dealt with a phantom connector issue that made a simple job drag on forever?

Honestly I used to always blame the big parts first, but a bad connector taught me to check the simple stuff.

Forget the simple stuff, sometimes the problem is a ghost in the system. I chased a weird bug for weeks that was just a tiny bit of software corruption. It makes you question EVERYTHING after that.
