LNDG WITHOUT CLRNC.

Narrative

AFTER LNDG AT MALPENSA TWR ADMONISHED US FOR FAILING TO RPT THE OM AND FOR LNDG WITHOUT A CLRNC. THE FO HAD DEFINITELY CALLED AT THE MALPENSA NDB; WHICH IS CO- LOCATED WITH THE OM; ON THE INITIAL CHK-IN WITH TWR. THE TWR CTLR RESPONDED WITH WORDS THAT WE TOOK TO MEAN ACKNOWLEDGING OUR POS AND CLRING US FOR APCH AND LNDG. THERE IS NO RADAR AT MALPENSA AND THE WX PRECLUDED VISUAL CONTACT BY THE TWR UNTIL LNDG ROLLOUT. ALL 3 OF US WERE EXPERIENCED AT MALPENSA AND WERE AWARE OF NOTHING UNUSUAL UNTIL TWR'S CALL AFTER WE LANDED. POSSIBLE CONTRIBUTING FACTORS WERE LANGUAGE DIFFERENCES AND FATIGUE ASSOCIATED WITH A LONG ALL NIGHT OVERWATER FLT. WE HAD DEALT WITH A PAX ILLNESS AND TURB AS BAD AS I HAVE SEEN; BOTH OF WHICH DISRUPTED THE NORMAL CREW REST CYCLE. I'M NOT SURE WHAT CORRECTIVE ACTION WOULD APPLY FOR THE OM POS RPT AS IT WAS DEFINITELY MADE AND RESPONDED TO. PERHAPS USE OF THE SPECIFIC TERM 'OM' RATHER THAN THE NAME OF THE CO-LOCATED NDB WOULD HAVE HELPED. AS FOR THE LNDG; THE OBVIOUS CORRECTIVE ACTION IS TO CONFIRM AND RECONFIRM LNDG CLRNC PRIOR TO LNDG. THE FINAL APCH FIX; COMPLETION OF LNDG CHKS; PASSING 1000 FT AGL; ACQUIRING VISUAL CONTACT WITH THE RWY AND APCHING SHORT FINAL WOULD ALL BE APPROPRIATE TIMES TO DO THIS.
