Narrative:
While cruising at our certified service ceiling altitude of FL410, the chief pilot, flying sic and myself, were vectoring around thunderstorm build-ups. I left my seat momentarily and when I had returned, I noticed that the chief pilot, without my knowledge, had climbed the aircraft above it's certified service altitude. I promptly descended the aircraft back down to FL410 when I became aware of his actions. He said he did it because we could get a 'better ride' higher up.
