Narrative:

We were departing teb airport; runway 19; flying the dalton departure procedure. The procedure requires a climb to at or below 1300 ft until radar identified and given a climb by ATC. Unfortunately; due to moderate turbulence; and the fact that I was slightly late initiating the level off; we exceeded the SID mandated altitude by approximately 100 ft. I immediately went back to the appropriate altitude of 1300 ft just as the departure controller took control of us and said that he showed us at 1400 ft. Before he could finish his sentence; we were already back at the correct altitude and there did not appear to be any conflicts with any other aircraft. The controller did not mention any problems nor did we have any TCAS alerts. I believe that there were three factors that contributed to this incident. The first and perhaps most significant was the turbulence. The new york area is notorious for turbulence especially during gusty wind conditions; and trying to execute a precise level off so soon after departure during conditions with excessive turbulence can be very difficult. Combining the difficult procedure with the very unstable flying conditions of this particular day proved momentarily; to be too much to handle all within a matter of 30 seconds. The final factor was CRM. The crew briefed the departure prior to takeoff but clearly I; as the flying pilot; did not put enough emphasis on the nearly immediate level off. Due to this error; co-captain during the departure; the situation was inevitable.
