Narrative:

Approach told us to follow commuter. Tower told us to follow air carrier MD80 who was well behind and above us. Tower told us to s-turn towards the west for spacing. After the s-turn it became apparent that spacing was tight (very tight). I asked tower if MD80 would hold short of our runway, they said 'yes.' if they had said no, I would have gone around. However, since they said yes and we were cleared to land, I continued with the landing. Both my aircraft and the air carrier jet ended up in the runway 33 and runway 36 intersection within 50 ft of each other. I feel that the tower controller put us in an unsafe position and that separation was lost.

Title: COMMUTER ACFT ON VISUAL APCH MUST S-TURN FOR SPACING AND STILL ENDS UP ONLY 50 FT FROM MD80 ON INTERSECTING RWYS ON LNDG ROLL.

Narrative: APCH TOLD US TO FOLLOW COMMUTER. TWR TOLD US TO FOLLOW ACR MD80 WHO WAS WELL BEHIND AND ABOVE US. TWR TOLD US TO S-TURN TOWARDS THE W FOR SPACING. AFTER THE S-TURN IT BECAME APPARENT THAT SPACING WAS TIGHT (VERY TIGHT). I ASKED TWR IF MD80 WOULD HOLD SHORT OF OUR RWY, THEY SAID 'YES.' IF THEY HAD SAID NO, I WOULD HAVE GONE AROUND. HOWEVER, SINCE THEY SAID YES AND WE WERE CLRED TO LAND, I CONTINUED WITH THE LNDG. BOTH MY ACFT AND THE ACR JET ENDED UP IN THE RWY 33 AND RWY 36 INTXN WITHIN 50 FT OF EACH OTHER. I FEEL THAT THE TWR CTLR PUT US IN AN UNSAFE POS AND THAT SEPARATION WAS LOST.
