Narrative:

Airport teb runway 24 SID teb 4. This departure requires to maintain 1500 ft until crossing 250 degree radial and after passing 4.5 teb climb to 3000 ft. My mistake was to start my climb to 3000 ft after crossing 250 degree radial and not waiting for the next limit which is 4.5 teb. Even though there was no conflict this time I recognized that leaving 1500 ft prematurely is a potential hazard to me and other aircraft. ATC asked me to maintain 1500 ft and the highest altitude was 1900 ft or 1950 ft and coming back to 1500 ft immediately. Contributing factor: after taking off, I tried to engage the autoplt and it did disengage. I tried again and this time it engaged but the light did not come on, so I disconnected the autoplt, flew the airplane, and after a few mins re-engaged the autoplt -- the light did not come on, but I tapped the switch and the light came on. From now on I am using the same short band that communication charts use. Single pilot operation. No other aircraft in 6 mi radius.

Original NASA ASRS Text

Title: C525 FLC CLB ABOVE ASSIGNED SID ALT AND ARE CHALLENGED BY N90.

Narrative: ARPT TEB RWY 24 SID TEB 4. THIS DEP REQUIRES TO MAINTAIN 1500 FT UNTIL XING 250 DEG RADIAL AND AFTER PASSING 4.5 TEB CLB TO 3000 FT. MY MISTAKE WAS TO START MY CLB TO 3000 FT AFTER XING 250 DEG RADIAL AND NOT WAITING FOR THE NEXT LIMIT WHICH IS 4.5 TEB. EVEN THOUGH THERE WAS NO CONFLICT THIS TIME I RECOGNIZED THAT LEAVING 1500 FT PREMATURELY IS A POTENTIAL HAZARD TO ME AND OTHER ACFT. ATC ASKED ME TO MAINTAIN 1500 FT AND THE HIGHEST ALT WAS 1900 FT OR 1950 FT AND COMING BACK TO 1500 FT IMMEDIATELY. CONTRIBUTING FACTOR: AFTER TAKING OFF, I TRIED TO ENGAGE THE AUTOPLT AND IT DID DISENGAGE. I TRIED AGAIN AND THIS TIME IT ENGAGED BUT THE LIGHT DID NOT COME ON, SO I DISCONNECTED THE AUTOPLT, FLEW THE AIRPLANE, AND AFTER A FEW MINS RE-ENGAGED THE AUTOPLT -- THE LIGHT DID NOT COME ON, BUT I TAPPED THE SWITCH AND THE LIGHT CAME ON. FROM NOW ON I AM USING THE SAME SHORT BAND THAT COM CHARTS USE. SINGLE PLT OP. NO OTHER ACFT IN 6 MI RADIUS.
