PLT FLIES TO DEST IN IMC WITH NO WX BRIEFING.

Narrative

MAKING AN IFR APCH INTO AN ARPT UNDER FAR 135 WITHOUT WX RPTING. ON THE NIGHT OF FEB/KK/95; I DEPARTED ON A SCHEDULED CARGO RUN IN AN AERO COMMANDER 680FL (AC68). IT WAS MY FIRST TIME ON THIS PARTICULAR RUN. I HAD PREVIOUSLY FLOWN INTO ALL OF THE ARPTS EXCEPT THE FINAL DEST; AND I FLEW THE AC 68 REGULARLY. AS PART OF MY PREPARATION I TALKED WITH A PLT WHO NORMALLY FLIES THE RUN; THE COMPANY DIRECTOR OF TRAINING. WE TALKED ABOUT WHERE TO PARK AT THE DIFFERENT ARPTS; HOW TO LOAD THE AIRPLANE; HOW TO GET TO THE MOTEL AFTER I WAS DONE. THEY DID NOT MENTION; AND OF COURSE IT WAS MY RESPONSIBILITY TO FIND OUT; THAT THE LAST ARPT HAD A PART TIME CTL ZONE. MY COMPANY FLIES INTO THIS ARPT 6 NIGHTS A WK. I ASSUMED THAT THERE WAS SOME SORT OF OFFICIAL WX RPTING AT THE ARPT. MY FIRST CLUE SHOULD HAVE COME FROM MY PREFLT BRIEFING. THE BRIEFER DID NOT GIVE ME DEST WX. HE GAVE ME THE WX AT A NEARBY ARPT. THERE WERE MDA'S ON THE DEST ARPT APCH PLATE FOR THE ALTIMETER SETTINGS HE WAS GIVING ME. I ASSUMED THAT IS HOW WE MADE THE APCH INTO THAT APCH. ON THE FINAL LEG OF THE FLT; I ASKED MYSELF 'WHY AM I DOING THIS; THERE IS NO WX AT THIS ARPT!' I DISMISSED THE THOUGHT. I TOLD MYSELF THAT MY COMPANY FLIES INTO THIS ARPT 6 NIGHTS A WK. IT HAS TO BE LEGAL. I MISSED THE APCH TWICE AND HAD TO RETURN TO THE PREVIOUS STOP. THE NEXT DAY; MY CHIEF PLT TOLD ME THAT I WAS SUPPOSED TO CALL THE ARPT MGR WHEN THE WX WAS DOWN. THE ARPT MGR WOULD GET OUT OF BED AND MAKE A WX OBSERVATION FOR US. NEVER ASSUME ANYTHING! THE NEXT TIME THAT I AM ASKING MYSELF 'WHY AM I DOING THIS;' I WILL STOP; TURN AROUND AND LAND; MAKE A PHONE CALL OR TWO AND GET MORE INFO. IT WOULD HAVE MEANT A LOT FEWER PROBS FOR ME ON THIS TRIP. THE COMPANY PLANS TO MAKE WRITTEN INSTRUCTIONS FOR EACH RTE THAT THEY FLY SO THAT IMPORTANT INFO WILL BE PASSED ALONG TO NEW PLTS ON THE RTES.
