NMAC BTWN AN ARR B737-300 AND A GLIDER ON THE EXTENDED CTRLINE OF LOC RWY 34R AT 11000 FT; 3 NM N OF FFU VORTAC; UT.

Narrative

WHILE DSNDING INTO SLC; JUST N OF FFU VOR; WE HAD JUST LEVELED AT 11000 FT AT 230 KTS FOR LIGHT TURB. WE WERE THEN CLRED FOR THE VISUAL APCH TO RWY 34R. I LOOKED AT MY APCH PLATE AND THEN THE FMC/CDU LEGS PAGE TO CONFIRM OUR NEXT ALT UNTIL PLAGE. MY FO STATED; 'CAPT; WE'VE GOT A GLIDER AT 12 O'CLOCK POS. WE NEED TO TURN R NOW AND DSND.' I DISCONNECTED THE AUTOPLT AND APPLIED R AILERON AND NOSE DOWN CTL INPUTS WHILE LOOKING FOR THE TFC. I SPOTTED THE SAIL PLANE AT OUR ALT; JUST L OF OUR NOSE; WITH NO RELATIVE MOTION IN MY WINDSCREEN; COMING NOSE ON. AS I ROLLED R AND DSNDED; THE SAIL PLANE PLT BANKED TO HIS L; TURNING DIRECTLY INTO OUR PATH. I INCREASED BANK ANGLE TO APPROX 40 DEGS AND NOSE DOWN PITCH TO APPROX 10-12 DEGS AND IGNORED THE AUDIBLE; 'BANK ANGLE' WARNINGS. AS THE SAIL PLANE PASSED DOWN THE L SIDE OF OUR ACFT; MISSING US BY APPROX 150 FT HORIZLY AND 30 FT VERTLY; I SAW THE PLT REVERSE HIS ROLL TO R BANK. WE LEVELED AT 9500 FT; RPTED THE NMAC TO APCH CTL FOR THE BENEFIT OF FOLLOWING ACR ACFT; AND COMPLETED THE APCH TO AND LNDG ON RWY 34R WITHOUT FURTHER INCIDENT. I HAD ALREADY SEATED THE FLT ATTENDANTS PRIOR TO THE INCIDENT; AND AFTER LNDG; THEY RPTED THAT NO PAX WERE INJURED OR OVERLY ALARMED. I THEN CALLED APCH CTL; DISPATCH; THE CHIEF PLT ON CALL; AND COMPLETED THE REQUIRED RPTS.
