Narrative:

While flying the teb 5 departure; I noticed a deviation of approximately 200 ft above required 1500 ft leveloff. I made note to PF to correct problem. Aircraft didn't alter to required altitude which appeared to be due to turbulence (moderate). I took control to manually return to 1500 ft and returned the aircraft to PF to complete the departure as published. 1) lengthy discussions over 2-3 days between both crew members suggested we change FMS procedures to better ensure both altitude and positioning is properly met to comply with the departure. 2) ensure good communications between crew members is established prior to departure to cover both normal and abnormal events (including turbulence) and potential autoplt problems associated with WX and/or system failures. 3) this specific departure is one which lends itself to various and difficult situations realizing the amount of traffic within the new york/new jersey area and would hope that a review of other incidents and/or problems give considerations to a safer and more viable departure procedure.

Title: A G-IV DEPARTING TEB ON THE TEB 5 DEP FAILED TO LEVEL OFF AT 1500 FT AS CHARTED; CLBING TO 1700 FT BEFORE DSNDING BACK TO 1500 FT.

Narrative: WHILE FLYING THE TEB 5 DEP; I NOTICED A DEV OF APPROX 200 FT ABOVE REQUIRED 1500 FT LEVELOFF. I MADE NOTE TO PF TO CORRECT PROB. ACFT DIDN'T ALTER TO REQUIRED ALT WHICH APPEARED TO BE DUE TO TURB (MODERATE). I TOOK CTL TO MANUALLY RETURN TO 1500 FT AND RETURNED THE ACFT TO PF TO COMPLETE THE DEP AS PUBLISHED. 1) LENGTHY DISCUSSIONS OVER 2-3 DAYS BTWN BOTH CREW MEMBERS SUGGESTED WE CHANGE FMS PROCS TO BETTER ENSURE BOTH ALT AND POSITIONING IS PROPERLY MET TO COMPLY WITH THE DEP. 2) ENSURE GOOD COMS BTWN CREW MEMBERS IS ESTABLISHED PRIOR TO DEP TO COVER BOTH NORMAL AND ABNORMAL EVENTS (INCLUDING TURB) AND POTENTIAL AUTOPLT PROBS ASSOCIATED WITH WX AND/OR SYSTEM FAILURES. 3) THIS SPECIFIC DEP IS ONE WHICH LENDS ITSELF TO VARIOUS AND DIFFICULT SITUATIONS REALIZING THE AMOUNT OF TFC WITHIN THE NEW YORK/NEW JERSEY AREA AND WOULD HOPE THAT A REVIEW OF OTHER INCIDENTS AND/OR PROBS GIVE CONSIDERATIONS TO A SAFER AND MORE VIABLE DEP PROC.
