Narrative:
On departure, I busted a 1500 ft MSL altitude restr, briefly leveling at 2000 ft before immediately returning to 1500 ft. Takeoff was on a SID of runway 24 towards a thundershower directly off the end of the runway. Climbed steeply to get to turn altitude in order to make turn away from thunderstorm. (Hand flying aircraft.) in the turn, overshot altitude by 500 ft. I had misread the SID and thought we were supposed to climb from 1500-2000 ft after passing the 4.5 DME arc. I had therefore set the altitude alerter to 2000 ft, planning to level off at 1500 ft on my own until 4.5 NM. In the distraction of urgent turn, overshot altitude. Error chain: 1) misreading a complicated SID. 2) setting the higher of presumed altitude restrs. 3) because 2000 ft was set in the altitude alerter (incorrectly), no flight director, or reminder would prompt leveloff at 1500 ft. This is a complete automation problem: improper procedure for phase (or lack of use) of automation selected, ie, I set myself up for an error without realizing it. In the future, I will read the SID closer and set the altitude alerter to the lower restr. You can always move it to the higher altitude after 1ST leveloff.

Title: CL60 CREW DEPARTED TEB ON RWY 24 DIRECTLY INTO A TSTM CELL. THE CREW HAD AN ALT OVERSHOOT AFTER MISSETTING THE ALT ALERT SYS AND MISREADING THE TEB 5 SID.
Narrative: ON DEP, I BUSTED A 1500 FT MSL ALT RESTR, BRIEFLY LEVELING AT 2000 FT BEFORE IMMEDIATELY RETURNING TO 1500 FT. TKOF WAS ON A SID OF RWY 24 TOWARDS A THUNDERSHOWER DIRECTLY OFF THE END OF THE RWY. CLBED STEEPLY TO GET TO TURN ALT IN ORDER TO MAKE TURN AWAY FROM TSTM. (HAND FLYING ACFT.) IN THE TURN, OVERSHOT ALT BY 500 FT. I HAD MISREAD THE SID AND THOUGHT WE WERE SUPPOSED TO CLB FROM 1500-2000 FT AFTER PASSING THE 4.5 DME ARC. I HAD THEREFORE SET THE ALT ALERTER TO 2000 FT, PLANNING TO LEVEL OFF AT 1500 FT ON MY OWN UNTIL 4.5 NM. IN THE DISTR OF URGENT TURN, OVERSHOT ALT. ERROR CHAIN: 1) MISREADING A COMPLICATED SID. 2) SETTING THE HIGHER OF PRESUMED ALT RESTRS. 3) BECAUSE 2000 FT WAS SET IN THE ALT ALERTER (INCORRECTLY), NO FLT DIRECTOR, OR REMINDER WOULD PROMPT LEVELOFF AT 1500 FT. THIS IS A COMPLETE AUTOMATION PROB: IMPROPER PROC FOR PHASE (OR LACK OF USE) OF AUTOMATION SELECTED, IE, I SET MYSELF UP FOR AN ERROR WITHOUT REALIZING IT. IN THE FUTURE, I WILL READ THE SID CLOSER AND SET THE ALT ALERTER TO THE LOWER RESTR. YOU CAN ALWAYS MOVE IT TO THE HIGHER ALT AFTER 1ST LEVELOFF.
