Brief Description: Tapping out and fitting wing tank drains.
Again found the drain inserts had resin in the threads. Borrowed a tapered and straight npt tap to clean out the threads - then loctited the drains in place. They are pulling up on the threads and not the shoulders so will check carefully when the tanks are full.
Put the panel back in and tested the repaired Dynon ADAHRS unit - all works well now ...
