Narrative:

Exceeded assigned altitude on climb out. Assigned altitude 7000 ft. Altitude reached 7450 ft. Observed by pilot and corrected in less than 1 min. Instrument scan interrupted by pilots observation of rapid ice build-up in cloud. Clouds 5000- 8000 ft MSL. Higher than normal rate of climb to 'on top' due to ice. No autoplt altitude preselect/alerter. Excess altitude observed by pilot and corrected by pilot in less than 1 min. Pilot obtained clearance to continue climb to 9000 ft MSL. Cloud tops higher than reported. Tops reported to be 6000 ft 1 hour before departure. Temperature lower than reported. Temperature reported 4 degrees C at 7000 ft MSL 1 hour before departure.

Title: PVT PLT IN A C210 OVERSHOT HIS ASSIGNED ALT ON CLB. SAYS HE WAS DISTRACTED BY ICE BUILDUP.

Narrative: EXCEEDED ASSIGNED ALT ON CLBOUT. ASSIGNED ALT 7000 FT. ALT REACHED 7450 FT. OBSERVED BY PLT AND CORRECTED IN LESS THAN 1 MIN. INST SCAN INTERRUPTED BY PLTS OBSERVATION OF RAPID ICE BUILD-UP IN CLOUD. CLOUDS 5000- 8000 FT MSL. HIGHER THAN NORMAL RATE OF CLB TO 'ON TOP' DUE TO ICE. NO AUTOPLT ALT PRESELECT/ALERTER. EXCESS ALT OBSERVED BY PLT AND CORRECTED BY PLT IN LESS THAN 1 MIN. PLT OBTAINED CLRNC TO CONTINUE CLB TO 9000 FT MSL. CLOUD TOPS HIGHER THAN RPTED. TOPS RPTED TO BE 6000 FT 1 HR BEFORE DEP. TEMP LOWER THAN RPTED. TEMP RPTED 4 DEGS C AT 7000 FT MSL 1 HR BEFORE DEP.
