Narrative: We were climbing out on the TEB 8 departure from Runway 24. We were supposed to level at 1;500 until 4.5 DME from TEB. I was the pilot not flying. We had briefed the departure and I had the text on my knee board. I called out 500 FT for 1;500 FT. While I was contacting Approach the pilot flying started the turn to a 280 heading but did not level off. By the time I could take control we had already reached 1;800 FT. The altitude alerter was set at 1;500 FT. For some reason the pilot flying thought she could continue the climb to 2;000 FT once we started the turn. The Approach Controller did not acknowledge the deviation and asked us to climb to 4;000 FT. It was just a mental error on the pilot flying because we had discussed in detail that I would let her know when we passed 4.5 DME and I would change the alerter to 2;000 FT and we could continue the climb.


Second narrative: As the First Officer and pilot flying this leg; I briefed the TEB8.TEB departure procedure; heading 240 to 1;500 FT; then right turn to 280 up to 2;000 FT until the 4.5 DME fix. This was incorrect and neither I nor the Captain challenged the brief. (The correct departure procedure was climb to 1;500 FT heading 240; then right turn to 280; maintain 1;500 FT until reaching the 4.5 DME fix; and then climb to 2;000 FT) I initially looked at the departure procedure but did not have it in front of me on takeoff. The Captain had the copy of the departure procedure on his lap. Being the first time I have flown the TEB8; I asked the Captain to watch me and make sure I was doing the right thing. He said he'd walk me through it and we continued to get ready to depart. Prior to departure I selected 2;000 FT in the altitude selector and he changed it to 1;500 FT but neither of us queried each other. On departure; I climbed to 1;500 FT on runway heading 240 degrees; made a right turn to 280 degrees and started to climb to 2;000 FT. After deviating 400 FT; the Captain made the call out '1;500 FT; 1;500 FT' and I immediately acted to correct my altitude. At the same exact time as the deviation; NY Departure cleared us up to 4;000 FT. They did not comment or query the deviation. It happened very quickly. Upon reflection; I can see that we failed in our CRM response as a crew. I should have had the plate in front of me the whole time for reference and should have taken more time to make sure I was reading it correctly. The Captain assumed I was more familiar with the departure and was distracted by traffic calls and ATC communication which led to him not catching the altitude deviation sooner.


Synopsis: An EA50 flight crew deviated from the TEB departure by climbing through the 1;500 FT restriction. First Officer was not clear on the procedure.
