FATIGUED BE36 PLT DSNDS 1000 FT BELOW MINIMUM ALT ON INTERMEDIATE LEG OF GPS-A APCH TO MIV.

Narrative

WHILE ON AN IFR FLT PLAN AND PRACTICING MULTIPLE APCHS INTO MIV; I REALIZED I HAD INADVERTENTLY DSNDED WELL BELOW A REQUIRED MINIMUM ALT. ATLANTIC CITY APCH HAD CLRED ME FOR THE VOR OR GPS-A APCH AND TOLD ME TO MAINTAIN 2000 FT UNTIL XING VCN AND TOLD ME TO SWITCH OVER TO ADVISORY FREQ. PRIOR TO XING VCN; I CHKED THE MDA FOR THE APCH AND SAW 600 FT. AFTER XING VCN; I DSNDED TO 600 FT. I THEN CHKED THE GPS FOR MY DISTANCE FROM THE ARPT SO I COULD RPT IT ON CTAF. IT WAS AT THAT POINT I SAW I WAS 3 MI FROM VINER INTXN AND SHOULD HAVE BEEN AT 1600 FT. I WAS 1000 FT TOO LOW! I IMMEDIATELY STARTED A CLB BACK TO 1600 FT BUT DID NOT REACH IT BEFORE THE INTXN. I THEN DSNDED BACK TO 600 FT TO COMPLETE THE APCH WHICH ENDED IN A MISSED APCH. I BELIEVE THERE WERE SEVERAL CONTRIBUTING FACTORS THAT LED TO THIS INCIDENT. FIRST WAS MY FATIGUE FROM WORKING A LONG DAY AND NOT GETTING ADEQUATE SLEEP THE NIGHT BEFORE. SECOND WAS MY LACK OF PREPARATION FOR THE APCH BY NOT ADEQUATELY REVIEWING THE APCH PLATE AND SEEING THE CORRECT ALTS TO MAINTAIN. THIRD WAS DOING MULTIPLE APCHS IN A SHORT PERIOD OF TIME. THIS COULD ALL HAVE BEEN AVOIDED HAD I NOT UNDERTAKEN THE FLT IN MY FATIGUED CONDITION.
