I was acting as copilot for the owner's son who is rated and current in the aircraft. He was PIC in the left seat, hand flying the airplane. Throughout the flight I had pointed out altdevs, on the order of 300 ft. At the time in question, the PIC was struggling to put on his headset and instead of asking me to fly, or use the autoplt, decided to let the airplane do it's own thing. We were high on altitude at the time and in the process gained approximately 500 ft, prompting a call from ATC. I acknowledged the call and immediately pushed the aircraft back on altitude. The PIC then turned on the autoplt, with altitude hold, and there was no more problem. Several things can be done to prevent reoccurrence: some work with cockpit resource management so 1 pilot is always flying the airplane, paying attention to altitude, more assertiveness in pointing out altitude deviation regardless of who the PIC is.

Title: FLC DEVIATES FROM ALT 500 FT.
Narrative: I WAS ACTING AS COPLT FOR THE OWNER'S SON WHO IS RATED AND CURRENT IN THE ACFT. HE WAS PIC IN THE L SEAT, HAND FLYING THE AIRPLANE. THROUGHOUT THE FLT I HAD POINTED OUT ALTDEVS, ON THE ORDER OF 300 FT. AT THE TIME IN QUESTION, THE PIC WAS STRUGGLING TO PUT ON HIS HEADSET AND INSTEAD OF ASKING ME TO FLY, OR USE THE AUTOPLT, DECIDED TO LET THE AIRPLANE DO IT'S OWN THING. WE WERE HIGH ON ALT AT THE TIME AND IN THE PROCESS GAINED APPROX 500 FT, PROMPTING A CALL FROM ATC. I ACKNOWLEDGED THE CALL AND IMMEDIATELY PUSHED THE ACFT BACK ON ALT. THE PIC THEN TURNED ON THE AUTOPLT, WITH ALT HOLD, AND THERE WAS NO MORE PROB. SEVERAL THINGS CAN BE DONE TO PREVENT REOCCURRENCE: SOME WORK WITH COCKPIT RESOURCE MGMNT SO 1 PLT IS ALWAYS FLYING THE AIRPLANE, PAYING ATTN TO ALT, MORE ASSERTIVENESS IN POINTING OUT ALTDEV REGARDLESS OF WHO THE PIC IS.
