Narrative:
Copilot hand flying to maintain flying skills. Leveled at 10000 ft MSL and began accelerating from 250 KTS to cruise speed. Departure gave us a 50 degree left turn to intercept the outbound radial. As the aircraft accelerated, we hit turbulence and climbed above 10000 ft. I informed the copilot to maintenance 10000 ft. He applied corrective action, but we climbed to 10500 ft before correcting to 10000 ft. Controller was very busy and didn't mention our altitude excursion. Shortly thereafter, we were cleared to climb to 17000 ft. This wouldn't have happened with autoplt engaged.

Title: ALTDEV ALT EXCURSION - FO HITS TURB WHILE HAND-FLYING THE ACFT AND CLBS 500 FT BEFORE RETURNING TO THE ASSIGNED ALT.
Narrative: COPLT HAND FLYING TO MAINTAIN FLYING SKILLS. LEVELED AT 10000 FT MSL AND BEGAN ACCELERATING FROM 250 KTS TO CRUISE SPD. DEP GAVE US A 50 DEG L TURN TO INTERCEPT THE OUTBOUND RADIAL. AS THE ACFT ACCELERATED, WE HIT TURB AND CLBED ABOVE 10000 FT. I INFORMED THE COPLT TO MAINT 10000 FT. HE APPLIED CORRECTIVE ACTION, BUT WE CLBED TO 10500 FT BEFORE CORRECTING TO 10000 FT. CTLR WAS VERY BUSY AND DIDN'T MENTION OUR ALT EXCURSION. SHORTLY THEREAFTER, WE WERE CLRED TO CLB TO 17000 FT. THIS WOULDN'T HAVE HAPPENED WITH AUTOPLT ENGAGED.
