LTT FLC IN CLB EXCEEDS ASSIGNED ALT BY 400 FT. RETURNS TO ASSIGNED.

Narrative

THERE ARE MANY FACTORS INVOLVED WITH THIS INCIDENT; BEYOND THE ACTUAL 'ALT BUST.' THOUGH I AM QUALIFIED AS A PART 135 CAPT ON OUR COMPANY ACFT; ON THIS DAY; I WAS SERVING AS THE FO; WITH MY 'BOSS' (EMPLOYER) DISPATCHED AS THE PIC. HOLDING SHORT OF NUQ RWY 14; WE WERE ASSIGNED AN ALT OF 3000 FT BY NUQ TWR. I RESET THE ALT ALERTER FROM OUR PREVIOUS ASSIGNED ALT DOWN TO THE NEW 3000 FT RESTRICTION. I THEN VERBALLY ANNOUNCED THE NEW ALT LIMIT; AND RECEIVED A VERBAL ACKNOWLEDGEMENT FROM THE CAPT. BASED ON MY OWN PREVIOUS EXPERIENCE WITH THIS PARTICULAR CAPT (AS WELL AS THOSE RELATED TO ME BY OUR OTHER PLT WHO HAVE FLOWN WITH HIM); UPON BEING CLRED FOR TKOF; I REITERATED THE 3000 FT ALT LIMIT; AND AGAIN; I RECEIVED A VERBAL ACKNOWLEDGEMENT. DURING CLBOUT; I NOTICED WHAT I CONSIDERED TO BE A HIGH RATE OF CLB; CONSIDERING OUR 3000 FT LIMIT. PASSING THROUGH 1000 FT; I DECIDED TO ANNOUNCE '2000 TO GO' (NOT A REQUIRED CALLOUT). GOING THROUGH 2000 FT; I STATED '1000 TO GO; 3000'S THE LIMIT.' AT 2500 FT; I CALLED OUT; VIRTUALLY SIMULTANEOUSLY; '500 TO GO; APCHING ALT!' AS WE PASSED THROUGH 3000 FT; I REACHED FOR THE PWR LEVERS TO REDUCE THE PWR AND I CALLED OUT 'YOU WENT THROUGH YOUR ALT; WE NEED TO GO DOWN TO 3000!' I SAW THE ALTIMETER TO READ AS HIGH AS 3400 AT ITS HIGHEST POINT. I THEN HEARD AN AIRLINER STATE THAT HIS TCASII HAD WARNED OF AN IMPENDING ACFT WITHIN 500 FT. THE CTLR IDENTED THAT ACFT TO THE AIRLINER AS BEING US. I HAVE HAD SEVERAL SITUATIONS OCCUR WITH THIS PARTICULAR CAPT; BUT THE FACT THAT HE IS MY BOSS AND THAT HE IS 37 YEARS MY SENIOR HAS MADE IT VERY DIFFICULT TO DEAL WITH THIS SITUATION. I AM CURRENTLY CONSIDERING ALTERNATIVES TO FLYING WITH HIM EVER AGAIN; WHILE STILL MAINTAINING MY EMPLOYMENT.
