A buddy of mine ran into the same thing on a 321 out in Phoenix, three drip calls in a month and every one came back NFF. Turned out the screen in the forward mast was caked solid with that dried blue junk, and once he pulled it and cleaned it the drips stopped cold. Funny how all that buildup gets blamed on the dry air when it is really just a plugged screen that nobody wants to pull.

Soda sugar fried the drift sensor, rice won't fix that. Send it in for real.

Embrace the free lesson, old heads know stuff you dont.
