LJ31 FLT CREW FAILS TO LEVEL AT 1500 FT PER TEB 5 SID.

Narrative

AFTER LOADING THE PAX AND STARTING THE ENGINES; I (PF) BEGAN TO TAXI WHILE THE CAPT (PNF) WAS RUNNING THE TAXI CHKLIST. THE CAPT WAS READING THE DEP PROC AND SETTING THE APPROPRIATE NAV AIDS AND THEN BRIEFED ME ON THE DEP (TEB 5) WHILE I TAXIED TO RWY 24. I THEN READ BACK TO HIM THE DEP PROC AS I UNDERSTOOD IT (DEP RWY 24 CLB TO 1500 FT THEN TURN R TO A HEADING OF 280 DEGS AND CLB TO 2000 FT). HE TOLD ME THAT WAS CORRECT AND SET THE ALT SELECTOR TO 1500 FT. WE COMPLETED THE CHKLISTS AND THEN DEPARTED RWY 24. ON DEP; I CLBED RWY HEADING TO 1500 FT THEN INITIATED A TURN TO HEADING 280 DEGS; ASKED THE CAPT TO RESET THE ALTITUDE SELECTOR TO 2000 FT AS I CONTINUED THE CLB TO 2000 FT. THE CAPT AT THIS POINT TOOK THE HANDOFF FROM THE CTL TWR TO CONTACT DEP. THE CAPT TOLD ME TO LEVEL OFF AT 1500 FT BECAUSE WE HAD NOT PASSED THE TEB 4.5 DME YET. I DID NOT UNDERSTAND WHAT HE WAS TELLING ME TO DO BECAUSE THAT WAS NOT HOW I UNDERSTOOD THE PROC OR BRIEFED HIM PREVIOUSLY. HE WAS LOOKING AT THE DEP PROC IN FRONT OF HIM SO I INITIATED A DESCENT TO RETURN BACK TO 1500 FT. ONCE WE PASSED THE 4.5 DME I INITIATED A CLB TO 2000 FT AND COMPLETED THE DEP PROC. I BELIEVE THERE WERE A FEW THINGS THAT LED UP TO NOT FLYING THE DEP PROC PROPERLY. FATIGUE WAS A FACTOR BECAUSE I HAD BEEN UP FOR OVER 15 HRS; ALTHOUGH I STILL WAS UNDER THE MAXIMUM DUTY TIME FOR THE DAY OF 14 HRS. SO WITH FATIGUE CAME COMPLACENCY IN THAT THE CAPT DID NOT CORRECT MY BRIEFING OF THE DEP PROC; ASSUMING I UNDERSTOOD THE PROC. ALSO THERE WAS A RUSH TO GET THE PAX TO THEIR DEST SO WE COULD RETURN HOME BEFORE EXCEEDING OUR MAX DUTY DAY. SO BY RUSHING TO GET OFF THE GND AS SOON AS POSSIBLE WE DID NOT SET UP AND BRIEF THE DEP PROC BEFORE INITIATING THE TAXI. TO CORRECT THE PROB; FIRST; WE SHOULD BE METHODICAL IN ALL CHKLISTS AND PROCS KNOWING THAT WE WERE FATIGUED AND MISTAKES CAN OCCUR. SECOND; WE SHOULD BACK EACH OTHER UP WHILE FLYING THE AIRPLANE AND MAKE SURE THE FLYING PLT IS FLYING THE PROPER HEADING; ALT AND PROC AS APPROPRIATE. THIRD; TO NOT BECOME COMPLACENT AND ASSUME THE OTHER PLT UNDERSTANDS THE GIVEN INSTRUCTIONS. FOURTH; NOT BE PRESSURED INTO GETTING BACK ON TIME CAUSING US TO BE HURRIED AND SKIP APPROPRIATE PROCS AND GIVING ALL ATTENTION TO THE APPROPRIATE TASK.
