Narrative:

I was in the l-hand seat as PNF, copilot in r-hand seat flying aircraft. Shortly after takeoff, on the teb 5 departure from teb airport (climb 1500 ft right turn 4.5 mi climb 2000 ft) when passing approximately 1000 ft we experienced an electrical spike on the #1 AC bus. My giro made a 60 degree down 25 degree left bank indication. #1 pitch and #1 roll channels disengaged. Yaw damper disengaged, as did altitude select mode and ht in altitude selector. My flight director disappeared. Copilot's flight director stayed in last position and was unable to respond to altitude capture mode. Whilst responding to the multiple failures, copilot flew aircraft to 2600 ft (instead of 1500 ft). I failed to alert copilot to this. We brought aircraft to 2000 ft (level required at 4.5 mi). We were by this time at 5.1 mi. I introduced a delay into the error as I found the SID instructions very hard to read. Prior to takeoff, cockpit lighting was much brighter. The text for the departure is very small. My first pair of prescription glasses had fallen to the base/back of the seat during the low level bumps after takeoff. Having already busted the altitude, I needed to review the SID to make sure I gave the correct ht to the copilot. Within the next few mins we had introduced the standby inverter to #1 AC bus and were able to reset flight director functions.

Title: MULTIPLE ELECTRICAL AND FLT GUIDANCE PROBS CAUSE THE DISTR THAT RESULTS IN AN ALT OVERSHOOT ON DEP FROM TEB, NJ.

Narrative: I WAS IN THE L-HAND SEAT AS PNF, COPLT IN R-HAND SEAT FLYING ACFT. SHORTLY AFTER TKOF, ON THE TEB 5 DEP FROM TEB ARPT (CLB 1500 FT R TURN 4.5 MI CLB 2000 FT) WHEN PASSING APPROX 1000 FT WE EXPERIENCED AN ELECTRICAL SPIKE ON THE #1 AC BUS. MY GIRO MADE A 60 DEG DOWN 25 DEG L BANK INDICATION. #1 PITCH AND #1 ROLL CHANNELS DISENGAGED. YAW DAMPER DISENGAGED, AS DID ALT SELECT MODE AND HT IN ALT SELECTOR. MY FLT DIRECTOR DISAPPEARED. COPLT'S FLT DIRECTOR STAYED IN LAST POS AND WAS UNABLE TO RESPOND TO ALT CAPTURE MODE. WHILST RESPONDING TO THE MULTIPLE FAILURES, COPLT FLEW ACFT TO 2600 FT (INSTEAD OF 1500 FT). I FAILED TO ALERT COPLT TO THIS. WE BROUGHT ACFT TO 2000 FT (LEVEL REQUIRED AT 4.5 MI). WE WERE BY THIS TIME AT 5.1 MI. I INTRODUCED A DELAY INTO THE ERROR AS I FOUND THE SID INSTRUCTIONS VERY HARD TO READ. PRIOR TO TKOF, COCKPIT LIGHTING WAS MUCH BRIGHTER. THE TEXT FOR THE DEP IS VERY SMALL. MY FIRST PAIR OF PRESCRIPTION GLASSES HAD FALLEN TO THE BASE/BACK OF THE SEAT DURING THE LOW LEVEL BUMPS AFTER TKOF. HAVING ALREADY BUSTED THE ALT, I NEEDED TO REVIEW THE SID TO MAKE SURE I GAVE THE CORRECT HT TO THE COPLT. WITHIN THE NEXT FEW MINS WE HAD INTRODUCED THE STANDBY INVERTER TO #1 AC BUS AND WERE ABLE TO RESET FLT DIRECTOR FUNCTIONS.
