Sikorsky Rotor Brakes have ruined more White Shirts than I care to remember....till finally we just surrendered and started wearing shirts with a pink left shoulder and sleeve.

Some time back had a 365 return with the instrument panel looking like Blackpool illuminations.
Traced to a missing grommet on a windshield wiper arm that had allowed rather a lot of water into the master electrical box in the nose.
When we dropped the cover we got a pint of water out. It was sloshing back and forth across the cards resulting in the amazing light display..
The surprise was that only one card was damaged everything else was fine once dried out.
