Narrative:

Upon receiving landing clearance from slc tower; myself and my student lined up for final approximately 2 mi from runway 35. We then heard the tower clear the metroliner for landing runway 32 behind our aircraft. As the flight progressed; I noticed the metroliner turning base for runway 32; approximately 1 mi east of our position. As the landing lights of the metroliner got brighter; with no relative motion to our aircraft. I queried the tower who responded saying; 'they are landing behind you.' we continued our descent and the metroliner continued inbound off our right wing. My student gave me control of the aircraft and I took evasive action turning to parallel runway 32 which was the metroliner's landing runway. At that point; we were approximately 100 ft AGL and the metroliner was 100 ft to our right and 50 ft above. At that moment the metroliner pitched up and I called on the radio that he was going around. The metroliner crossed above our aircraft and made a radio call stating that he was not going around and continued his landing. I then lined up our aircraft with runway 35 and handed the controls back to my student. We landed safely and the tower instructed us to contact ground. The metroliner indicated over the radio that he had lost our aircraft in the ground clutter and the tower stated that the metroliner had probably scared us.

Title: PA28 AND SW4 HAVE NMAC ON APCH TO DIVERGING RWYS AT SLC.

Narrative: UPON RECEIVING LNDG CLRNC FROM SLC TWR; MYSELF AND MY STUDENT LINED UP FOR FINAL APPROX 2 MI FROM RWY 35. WE THEN HEARD THE TWR CLR THE METROLINER FOR LNDG RWY 32 BEHIND OUR ACFT. AS THE FLT PROGRESSED; I NOTICED THE METROLINER TURNING BASE FOR RWY 32; APPROX 1 MI E OF OUR POS. AS THE LNDG LIGHTS OF THE METROLINER GOT BRIGHTER; WITH NO RELATIVE MOTION TO OUR ACFT. I QUERIED THE TWR WHO RESPONDED SAYING; 'THEY ARE LNDG BEHIND YOU.' WE CONTINUED OUR DSCNT AND THE METROLINER CONTINUED INBOUND OFF OUR R WING. MY STUDENT GAVE ME CTL OF THE ACFT AND I TOOK EVASIVE ACTION TURNING TO PARALLEL RWY 32 WHICH WAS THE METROLINER'S LNDG RWY. AT THAT POINT; WE WERE APPROX 100 FT AGL AND THE METROLINER WAS 100 FT TO OUR R AND 50 FT ABOVE. AT THAT MOMENT THE METROLINER PITCHED UP AND I CALLED ON THE RADIO THAT HE WAS GOING AROUND. THE METROLINER CROSSED ABOVE OUR ACFT AND MADE A RADIO CALL STATING THAT HE WAS NOT GOING AROUND AND CONTINUED HIS LNDG. I THEN LINED UP OUR ACFT WITH RWY 35 AND HANDED THE CTLS BACK TO MY STUDENT. WE LANDED SAFELY AND THE TWR INSTRUCTED US TO CONTACT GND. THE METROLINER INDICATED OVER THE RADIO THAT HE HAD LOST OUR ACFT IN THE GND CLUTTER AND THE TWR STATED THAT THE METROLINER HAD PROBABLY SCARED US.
