Narrative:

After takeoff from runway 24; teb; started climb via the teb 5 departure to initial altitude of 1500 ft. Encountering turbulence in the climb; overshot level off altitude by 300 to 400 ft. Returned to assigned altitude. Altitude bust facilitated by lack of real currency in the aircraft. With over 1;000 hours of G-4 experience; this was only the 3RD flight for me in the G-450 after a 7 year gap in which I operated other types of aircraft. Could possibly have prevented this incident by engaging the autopilot after takeoff in the flch mode rather than hand flying.

Narrative: AFTER TAKEOFF FROM RWY 24; TEB; STARTED CLIMB VIA THE TEB 5 DEP TO INITIAL ALT OF 1500 FT. ENCOUNTERING TURB IN THE CLIMB; OVERSHOT LEVEL OFF ALT BY 300 TO 400 FT. RETURNED TO ASSIGNED ALT. ALT BUST FACILITATED BY LACK OF REAL CURRENCY IN THE ACFT. WITH OVER 1;000 HOURS OF G-4 EXPERIENCE; THIS WAS ONLY THE 3RD FLT FOR ME IN THE G-450 AFTER A 7 YEAR GAP IN WHICH I OPERATED OTHER TYPES OF ACFT.
