Narrative:

Executing noise abatement takeoff. Maximum power, brake release, rotate 26 degrees deck angle, gear up. Fly V2-V2+15, climb power at 800', adjust deck angle, navigation by flight director, cross reference localizer outbnd and magenta line on CRT to point 1 mi from end of runway, then turn to 175 degrees and level at 3000'. On this particular day, magenta line was left, localizer was right, flight director was center. Simultaneously tower called new traffic 12 O'clock, 3000'. Moment of confusion, turned to 175 degrees and blew by 3000' on to 3400' before able to stop climb. Went back to 3000'. Too much to do, too little time when things happen. Small aircraft crossed our bow close in by a few hundred feet and below us. If we had been steady level at 3000'...???

Title: FLT CREW OF LGT DEPARTING SNA HAD NMAC AT 3000' MSL.

Narrative: EXECUTING NOISE ABATEMENT TKOF. MAX PWR, BRAKE RELEASE, ROTATE 26 DEGS DECK ANGLE, GEAR UP. FLY V2-V2+15, CLB PWR AT 800', ADJUST DECK ANGLE, NAV BY FLT DIRECTOR, CROSS REF LOC OUTBND AND MAGENTA LINE ON CRT TO POINT 1 MI FROM END OF RWY, THEN TURN TO 175 DEGS AND LEVEL AT 3000'. ON THIS PARTICULAR DAY, MAGENTA LINE WAS LEFT, LOC WAS RIGHT, FLT DIRECTOR WAS CENTER. SIMULTANEOUSLY TWR CALLED NEW TFC 12 O'CLOCK, 3000'. MOMENT OF CONFUSION, TURNED TO 175 DEGS AND BLEW BY 3000' ON TO 3400' BEFORE ABLE TO STOP CLB. WENT BACK TO 3000'. TOO MUCH TO DO, TOO LITTLE TIME WHEN THINGS HAPPEN. SMA CROSSED OUR BOW CLOSE IN BY A FEW HUNDRED FEET AND BELOW US. IF WE HAD BEEN STEADY LEVEL AT 3000'...???
