Narrative:

With an experienced copilot flying, we were cleared to climb to 12000 ft and given a left turn. With a light aircraft, the rate of climb was great. We were issued inbound traffic at 13000 ft. Even though my copilot began to level off, our altitude reached 12100-12140 ft. Our high rate of climb caused a TCASII alert. In my opinion safety was never compromised, although allowing a copilot extra latitude with distraction present may have been inappropriate.

Title: ACR EXCEEDS ASSIGNED ALT ON CLB, CAUSES TCASII TA.

Narrative: WITH AN EXPERIENCED COPLT FLYING, WE WERE CLRED TO CLB TO 12000 FT AND GIVEN A L TURN. WITH A LIGHT ACFT, THE RATE OF CLB WAS GREAT. WE WERE ISSUED INBOUND TFC AT 13000 FT. EVEN THOUGH MY COPLT BEGAN TO LEVEL OFF, OUR ALT REACHED 12100-12140 FT. OUR HIGH RATE OF CLB CAUSED A TCASII ALERT. IN MY OPINION SAFETY WAS NEVER COMPROMISED, ALTHOUGH ALLOWING A COPLT EXTRA LATITUDE WITH DISTR PRESENT MAY HAVE BEEN INAPPROPRIATE.
