Pro tip: check the connector pins before you blame the black box

I was in Wichita last week doing a pitot static check on a King Air and the left airspeed was reading 15 knots low on the ramp, so I pulled the ADTS and started swapping out the air data computer, which is a $4,200 part. Turned out the actual issue was a bent pin in the cannon plug behind the panel that a previous shop had jammed in there, and I only found it after I wiggled the harness while watching the reading flicker. How many of you do a full pin drag test before you even touch the box, or do you trust the fault code like I did for two hours?

Did you even wiggle the harness first?
