A B727-100 CREW DSNDED EARLY WHILE FLYING A VOR DME APCH.

Narrative

AS WE APCHED NASSAU; I COPIED THE ATIS FOR THE CAPT WITH ATIS INFO; XA00Z; WIND 060 DEGS AT 7 KTS; VISIBILITY 2 MI IN LIGHT RAIN; BROKEN 1400 FT; BROKEN 1800 FT; OVCST 9000 FT; TEMP 72 DEGS; DEWPOINT 68 DEGS; ALTIMETER 29.98; CONDITIONS IMC. CONTACTING NASSAU APCH WE WERE CLRED DOWN TO 1500 FT AND CLRED FOR THE VOR DME RWY 9 APCH. THIS APCH INVOLVES FLYING A COURSE OR 106 DEGS TO THE NASSAU VOR; MAINTAINING 1500 FT UNTIL 7 DME; AND THEN DSNDING TO THE MDA OF 440 DEGS. MISSED APCH POINT IS A 2 DME. AT AROUND 10 DME; THE CAPT DSNDED OUT OF 1500 FT. I WAS NOT SURE WHAT HE WAS DOING; OR WHY HE WAS DSNDING EARLY. DUE TO OUR CONFLICT EARLIER IN THE DAY I WAS RELUCTANT TO SAY ANYTHING. WE HAD GND CONTACT AND WERE CLR OF CLOUDS BUT COULD NOT SEE THE ARPT. HE DSNDED THROUGH 1000 FT; AND AT 500 FT I SAID '500 FT.' HE REPLIED 'WE'RE [IN TROUBLE] IF WE GO INTO THESE CLOUDS.' I THEN UNDERSTOOD HIS TENT TO DUCK UNDER THE CLOUDS TO REMAIN CLR OF CLOUDS REGARDLESS OF THE MINIMUM ALTS OF THE APCH. HE EVENTUALLY DSNDED TO 380 FT MSL. MY RADIO ALTIMETER WAS SET TO THE MINIMUM AGL ALT OF 430 FT AND THE DECISION HT LIGHT WAS ILLUMINATED. WE SAW THE RWY AND LANDED. HE HAD MADE IT CLR EARLIER IN THE DAY HE REGARDED ME AS INSUBORDINATE DUE TO THE CONFLICT WE HAD OVER HIS NAV ERROR. I WAS AFRAID FOR MY JOB IF I SAID ANYTHING. I WAS EAGER TO REMAIN ON GOOD TERMS WITH HIM. MY LACK OF CRITICISM IN THIS MATTER DID NOT SATISFY HIM. HOWEVER; HE DID NOT LET ME FLY EITHER OF THE 2 LEGS WE FLEW THE NEXT DAY EITHER. WHEN I ASKED HIM ABOUT THIS AT THE END OF THE DAY; HE SAID HE WOULD ONLY LET ME FLY THE AIRPLANE IF I WAS 'NICE' TO HIM.
