Narrative:

Runway 19R, wind 220/18, landing sna, clear day, gusty winds. Approximately 100' AGL, airspeed loss of approximately 20 KIAS. Abruptly applied power and while engines spooled up lost another 50'. At T/D, gusting wind increased speed to bug +10. Touched down on left main about the same time engines reached full spool. Aircraft then settled on right main gear with nose high attitude. Elected to go around (5000' runway give very little room for error). Hit the to/GA switches, applied maximum power and hand-flew the aircraft to 2000'. Elected to leave flaps at 15 degrees and return to land and was cleared to 3000'. While reprogramming FMC and selecting mode to re-engage automatic throttles, flew threw 3000 to 3400'. Descending back to 3000'. Returned to the airport for normal landing. Factors contributing to altitude excursion: noise abatement procedure at sna is difficult enough west/O throwing in turmoil created by go around. Aci in jump seat, hence added stress for smoothie, procedure was increased. Then concentration on automation rather than just flying aircraft was enough distraction to fly through the altitude.

Title: ACR MLG ALT DEVIATION OVERSHOT DURING CLIMBOUT FROM LNDG GO AROUND AT SNA WITH ACR OBSERVING.

Narrative: RWY 19R, WIND 220/18, LNDG SNA, CLR DAY, GUSTY WINDS. APPROX 100' AGL, AIRSPD LOSS OF APPROX 20 KIAS. ABRUPTLY APPLIED PWR AND WHILE ENGS SPOOLED UP LOST ANOTHER 50'. AT T/D, GUSTING WIND INCREASED SPD TO BUG +10. TOUCHED DOWN ON LEFT MAIN ABOUT THE SAME TIME ENGS REACHED FULL SPOOL. ACFT THEN SETTLED ON RIGHT MAIN GEAR WITH NOSE HIGH ATTITUDE. ELECTED TO GO AROUND (5000' RWY GIVE VERY LITTLE ROOM FOR ERROR). HIT THE TO/GA SWITCHES, APPLIED MAX PWR AND HAND-FLEW THE ACFT TO 2000'. ELECTED TO LEAVE FLAPS AT 15 DEGS AND RETURN TO LAND AND WAS CLRED TO 3000'. WHILE REPROGRAMMING FMC AND SELECTING MODE TO RE-ENGAGE AUTO THROTTLES, FLEW THREW 3000 TO 3400'. DSNDING BACK TO 3000'. RETURNED TO THE ARPT FOR NORMAL LNDG. FACTORS CONTRIBUTING TO ALT EXCURSION: NOISE ABATEMENT PROC AT SNA IS DIFFICULT ENOUGH W/O THROWING IN TURMOIL CREATED BY GAR. ACI IN JUMP SEAT, HENCE ADDED STRESS FOR SMOOTHIE, PROC WAS INCREASED. THEN CONCENTRATION ON AUTOMATION RATHER THAN JUST FLYING ACFT WAS ENOUGH DISTR TO FLY THROUGH THE ALT.
