In our company, years ago a kingAir had a strike, entering the airframe via a propblade, leaving it via the wing. Result: no probs inflight, maintenance to planetary gear inside engine required. (hardened gear parts getting "soft" by the heat, I was told) Very expensive. Cheyenne was struck 3 times in a row and had just 3 little holes...
Neither cases showed any probs in avionics.
But another KingAir had a intermittend working GPS sensor, which was blamed to a strike.
