My old boss in Tampa told me to always trust the built-in test on the Garmin G1000
He said if the BIT passed, the box was good, no matter what the plane's logs said. I followed that for years until a King Air came in with a weird autopilot fault. The BIT was green, but a deeper check showed a bad roll servo channel. That advice cost us two days of downtime. How do you guys decide when to trust the built-in tests versus digging deeper?

But what about intermittent faults the BIT won't catch? I'd always start with the logs first.

Ever had one of those ghosts in the machine that only shows up when you're not looking? Logs are the only thing that ever gave me a clue on those. Otherwise you're just guessing.

Totally agree with @sagecooper. Logs are your best friend for those random glitches. I've seen systems pass every built-in test but still fail at weird times. The logs showed a memory leak that only happened after days of uptime. Without checking them first, you're just swapping parts and hoping.
