Narrative:
Night ILS approach in snow into flg. Captain flew instrument approach. First officer failed to make CTAF position reports at uncontrolled airport. Normal and uneventful landing. However, snowplows were on the runway at time of landing, near the far end of runway 21. I believe the high workload involved with the night approach in snow was the biggest contributor to the first officer not making radio calls which would have alerted the snowplow. ATC sent us to CTAF during a very busy portion of the approach. ATC, ASOS, or company dispatch never mentioned the snowplowing in progress. First officer had not flown in 16 days and was 'behind' his duties during most of the flight. First officer had very limited experience in the aircraft. Supplemental information from acn 634582: the WX was down to minimums on the approach. Abq cleared us to the CTAF late (after the FAF).

Title: A DH82 CREW FAILED TO CALL FINAL AT A CTAF ARPT AND LANDED WHILE SNOWPLOWS WERE EXITING THE RWY.
Narrative: NIGHT ILS APCH IN SNOW INTO FLG. CAPT FLEW INST APCH. FO FAILED TO MAKE CTAF POS RPTS AT UNCTLED ARPT. NORMAL AND UNEVENTFUL LNDG. HOWEVER, SNOWPLOWS WERE ON THE RWY AT TIME OF LNDG, NEAR THE FAR END OF RWY 21. I BELIEVE THE HIGH WORKLOAD INVOLVED WITH THE NIGHT APCH IN SNOW WAS THE BIGGEST CONTRIBUTOR TO THE FO NOT MAKING RADIO CALLS WHICH WOULD HAVE ALERTED THE SNOWPLOW. ATC SENT US TO CTAF DURING A VERY BUSY PORTION OF THE APCH. ATC, ASOS, OR COMPANY DISPATCH NEVER MENTIONED THE SNOWPLOWING IN PROGRESS. FO HAD NOT FLOWN IN 16 DAYS AND WAS 'BEHIND' HIS DUTIES DURING MOST OF THE FLT. FO HAD VERY LIMITED EXPERIENCE IN THE ACFT. SUPPLEMENTAL INFO FROM ACN 634582: THE WX WAS DOWN TO MINIMUMS ON THE APCH. ABQ CLRED US TO THE CTAF LATE (AFTER THE FAF).
