Narrative:
Climbing out of ewr on ewr 6. Aircraft on autoplt climbing to 6000 ft in profile mode turning to intercept col 350 degree radial. Aircraft exceeded 6000 ft by 200 ft, +/-50 ft. Autoplt did not capture altitude. Autoplt disengaged by me. Aircraft hand flown down to 6000 ft. During descent, aircraft flown to 5800 ft MSL. I corrected back to 6000 ft and leveled off. Remainder of flight was uneventful. I do not know why the autoplt didn't capture. 6000 ft was set in altitude alerter and I'm certain the FMS was armed. Perhaps the climb rate was such, greater than 3000 FPM, the autoplt didn't have time to capture.

Title: CAPT OF AN AIRBUS A310, OVERSHOT INTERMEDIATE ALT DURING DEP CLB AND THEN OVERSHOT ASSIGNED ALT UPON RETURN.
Narrative: CLBING OUT OF EWR ON EWR 6. ACFT ON AUTOPLT CLBING TO 6000 FT IN PROFILE MODE TURNING TO INTERCEPT COL 350 DEG RADIAL. ACFT EXCEEDED 6000 FT BY 200 FT, +/-50 FT. AUTOPLT DID NOT CAPTURE ALT. AUTOPLT DISENGAGED BY ME. ACFT HAND FLOWN DOWN TO 6000 FT. DURING DSCNT, ACFT FLOWN TO 5800 FT MSL. I CORRECTED BACK TO 6000 FT AND LEVELED OFF. REMAINDER OF FLT WAS UNEVENTFUL. I DO NOT KNOW WHY THE AUTOPLT DIDN'T CAPTURE. 6000 FT WAS SET IN ALT ALERTER AND I'M CERTAIN THE FMS WAS ARMED. PERHAPS THE CLB RATE WAS SUCH, GREATER THAN 3000 FPM, THE AUTOPLT DIDN'T HAVE TIME TO CAPTURE.
