I was working on a Citation's autopilot in Wichita last week and realized I've been seeing way more CAN bus issues than ARINC 429 these past three years.

Interesting, my shop has had the opposite experience. We still pull way more 429 cards for weird faults. Maybe it depends on the fleet mix.

Got to disagree on that one. CAN bus problems are way up across the board, not just certain fleets. The data shows a clear trend.

The tech at our local dealer told me they've seen a 40% jump in CAN bus tickets this year alone. That lines up with what you're saying, @victor_ward. It feels like a real industry-wide headache now.
