Narrative:

First officer briefed the captain about the departure SID and our clearance. We were #1 for takeoff. Takeoff clearance was delayed for about 50 mins due to traffic. During this long wait first officer again briefed the captain about the departure SID route, climb to 2000 ft and proceed to NDB. After passing NDB climb to 3000 ft. Captain climbed to 2600 ft before reaching the NDB. When first officer first saw the missed clearance, advised the captain of it. Then returned to the correct altitude. No conflict with traffic occurred. This is a human performance problem. As we try to meet the noise abatement procedure and SID procedures and ATC procedures and make a safe takeoff and many radio changes, too much is happening at the same time for the unfamiliar to this new area to handle, something will always get missed. One major factor was the long delay at the runway where the mind then goes blank. The departure times need to be more accurate or hold traffic at the gates before engine start. We need to help lower the actions and workload that occurs right after takeoff in order to improve safety.

Title: AIR TAXI EXCEEDS PUBLISHED ALT FLYING SID.

Narrative: FO BRIEFED THE CAPT ABOUT THE DEP SID AND OUR CLRNC. WE WERE #1 FOR TKOF. TKOF CLRNC WAS DELAYED FOR ABOUT 50 MINS DUE TO TFC. DURING THIS LONG WAIT FO AGAIN BRIEFED THE CAPT ABOUT THE DEP SID RTE, CLB TO 2000 FT AND PROCEED TO NDB. AFTER PASSING NDB CLB TO 3000 FT. CAPT CLBED TO 2600 FT BEFORE REACHING THE NDB. WHEN FO FIRST SAW THE MISSED CLRNC, ADVISED THE CAPT OF IT. THEN RETURNED TO THE CORRECT ALT. NO CONFLICT WITH TFC OCCURRED. THIS IS A HUMAN PERFORMANCE PROBLEM. AS WE TRY TO MEET THE NOISE ABATEMENT PROC AND SID PROCS AND ATC PROCS AND MAKE A SAFE TKOF AND MANY RADIO CHANGES, TOO MUCH IS HAPPENING AT THE SAME TIME FOR THE UNFAMILIAR TO THIS NEW AREA TO HANDLE, SOMETHING WILL ALWAYS GET MISSED. ONE MAJOR FACTOR WAS THE LONG DELAY AT THE RWY WHERE THE MIND THEN GOES BLANK. THE DEP TIMES NEED TO BE MORE ACCURATE OR HOLD TFC AT THE GATES BEFORE ENG START. WE NEED TO HELP LOWER THE ACTIONS AND WORKLOAD THAT OCCURS RIGHT AFTER TKOF IN ORDER TO IMPROVE SAFETY.
