Narrative:

We had been cleared direct to robinsville VOR after departing jfk up to 14000 ft. Passing 13000 ft, we were given a TA from N90. I engaged the autoplt and selected 14000 ft in the altitude select window and began searching for the traffic which my first officer was already looking for at the time. When I looked back down the aircraft was passing through 14250 ft. Instead of doing a hard nose over I smoothly, but firmly, stopped the climb at 14330 ft and immediately returned to 14000 ft. There was no comment from departure concerning our deviation and were soon handed off to ZNY without further incident. Simply put, I made a mistake. Both heads were out the window during other than level flight. I have since adopted a policy that the PNF will look for traffic while the PF does just that -- fly! I learned a lesson -- hopefully without loss.

Narrative: WE HAD BEEN CLRED DIRECT TO ROBINSVILLE VOR AFTER DEPARTING JFK UP TO 14000 FT. PASSING 13000 FT, WE WERE GIVEN A TA FROM N90. I ENGAGED THE AUTOPLT AND SELECTED 14000 FT IN THE ALT SELECT WINDOW AND BEGAN SEARCHING FOR THE TFC WHICH MY FO WAS ALREADY LOOKING FOR AT THE TIME. WHEN I LOOKED BACK DOWN THE ACFT WAS PASSING THROUGH 14250 FT. INSTEAD OF DOING A HARD NOSE OVER I SMOOTHLY, BUT FIRMLY, STOPPED THE CLB AT 14330 FT AND IMMEDIATELY RETURNED TO 14000 FT. THERE WAS NO COMMENT FROM DEP CONCERNING OUR DEV AND WERE SOON HANDED OFF TO ZNY WITHOUT FURTHER INCIDENT. SIMPLY PUT, I MADE A MISTAKE. BOTH HEADS WERE OUT THE WINDOW DURING OTHER THAN LEVEL FLT. I HAVE SINCE ADOPTED A POLICY THAT THE PNF WILL LOOK FOR TFC WHILE THE PF DOES JUST THAT -- FLY! I LEARNED A LESSON -- HOPEFULLY WITHOUT LOSS.
