BE35 AND MLG EXPERIENCE NMAC ON DESCENT TO MMML.

Narrative

INBOUND TO LNDG MMML WHILE LEVEL AT 8500 FT; I WAS OVERTAKEN FROM BEHIND BY AN MLG ALSO ON APCH TO MMML. PASSED APPROX 200 FT UNDER MY ACFT AND SLIGHTLY TO THE R AT HIGH SPD; MAYBE 320 KIAS. OCCURRED ABOUT 35 MI SE OF MMML. I HAD ALREADY CHKED IN WITH MMML TWR AT 52 NM E AND THE TWR KNEW MY POS. I HEARD THE MLG CHK IN WITH THE TWR CTLR; AFTER I CHKED IN; BUT DIDN'T HEAR THE WORD 'BONANZA' FROM THE CTLR; SO I WASN'T SURE IF HE WAS INBOUND AND IF SO; IF HE WAS INFORMED BY THE CTLR THAT I WAS AHEAD OF HIM INBOUND TO THE SAME RWY. THEN IT WAS QUIET -- UNTIL AFTER HE WENT BY ME. THEN THERE WAS A LOT OF TALK BTWN THE PLT AND THE CTLR -- ALL IN SPANISH. THEN THE CTLR ASKED ME MY POS AND ALT. I GAVE HIM THAT AND THEN I ALSO REMINDED HIM THAT I HAD CHKED IN WITH HIM AT 52 NM OUT AND THAT HE TOLD ME TO RPT 20 NM OUT; WHICH WAS STILL APPROX 10 NM AHEAD. HE SAID ROGER AND THAT WAS IT. IF THE MLG HAD TCAS; THERE WAS NO REASON FOR HIM TO PASS SO CLOSE TO MY ACFT. I HAD THE IMPRESSION THAT HE WAS 'BUZZING' ME.
