The problem: continued climb 300' above assigned altitude because I failed to promptly set the 'altitude sel' mode on the autoplt and failed to properly monitor my altitude. The altitude alerter was set properly and this called my attention to the problem at 12200' MSL. The cause: although both my copilot and I had observed the rest requirements of far 135, our day had been quite long and our sleep fitful. We were both tired and just not performing at our best. Contributing: this was our final leg after dropping off a patient, nurses were asleep and we were relaxed, enjoying the night flying.

Title: AIR AMBULANCE OVERSHOT ALT ON CLIMB.
Narrative: THE PROB: CONTINUED CLB 300' ABOVE ASSIGNED ALT BECAUSE I FAILED TO PROMPTLY SET THE 'ALT SEL' MODE ON THE AUTOPLT AND FAILED TO PROPERLY MONITOR MY ALT. THE ALT ALERTER WAS SET PROPERLY AND THIS CALLED MY ATTN TO THE PROB AT 12200' MSL. THE CAUSE: ALTHOUGH BOTH MY COPLT AND I HAD OBSERVED THE REST REQUIREMENTS OF FAR 135, OUR DAY HAD BEEN QUITE LONG AND OUR SLEEP FITFUL. WE WERE BOTH TIRED AND JUST NOT PERFORMING AT OUR BEST. CONTRIBUTING: THIS WAS OUR FINAL LEG AFTER DROPPING OFF A PATIENT, NURSES WERE ASLEEP AND WE WERE RELAXED, ENJOYING THE NIGHT FLYING.
