Narrative:

Cpr X on short final to runway 18L. Having been cleared to land, I heard air carrier Y call left base to runway 23. Assuming this aircraft must be fairly close-in, I looked to my left and observed medium large transport in an extremely steep nose down attitude in an apparent 'dive' to runway 23. I advised copilot. At this point, we were over the numbers of runway 18L and medium large transport was nearly as close in. Realizing this was going to get extremely close, I advised first officer of my intention to keep it high and land beyond the intersection. A few seconds later I could see even that was going to be too close, and as I was making my decision to go around, tower ordered us to go around. Airspeed was slow and altitude about 200 ft AGL. We passed directly over the medium large transport at intersection of runways with clearance estimated by first officer of less than 100 ft. As we were on the go, we also heard the medium large transport initiate a go around. Apparently, his radical approach left him with too much airspeed to stop on remaining runway. Had I not looked out of the window and noticed this aircraft, a collision, in my opinion, would have been unavoidable. My decision to stop my descent to the runway, in my mind, helped to avoid a catastrophe. I contacted controling facility and they leaned toward blaming air carrier Y for not slowing down on approach. This was probably a contributing factor, but without talking to the other pilot one can only make assumptions.

Title: CPR X ON GAR HAD NMAC WITH ACR Y ON GAR. MULTIPLE RWY OP INTERSECTING RWYS.

Narrative: CPR X ON SHORT FINAL TO RWY 18L. HAVING BEEN CLRED TO LAND, I HEARD ACR Y CALL L BASE TO RWY 23. ASSUMING THIS ACFT MUST BE FAIRLY CLOSE-IN, I LOOKED TO MY L AND OBSERVED MLG IN AN EXTREMELY STEEP NOSE DOWN ATTITUDE IN AN APPARENT 'DIVE' TO RWY 23. I ADVISED COPLT. AT THIS POINT, WE WERE OVER THE NUMBERS OF RWY 18L AND MLG WAS NEARLY AS CLOSE IN. REALIZING THIS WAS GOING TO GET EXTREMELY CLOSE, I ADVISED FO OF MY INTENTION TO KEEP IT HIGH AND LAND BEYOND THE INTXN. A FEW SECONDS LATER I COULD SEE EVEN THAT WAS GOING TO BE TOO CLOSE, AND AS I WAS MAKING MY DECISION TO GAR, TWR ORDERED US TO GAR. AIRSPD WAS SLOW AND ALT ABOUT 200 FT AGL. WE PASSED DIRECTLY OVER THE MLG AT INTXN OF RWYS WITH CLRNC ESTIMATED BY FO OF LESS THAN 100 FT. AS WE WERE ON THE GO, WE ALSO HEARD THE MLG INITIATE A GAR. APPARENTLY, HIS RADICAL APCH LEFT HIM WITH TOO MUCH AIRSPD TO STOP ON REMAINING RWY. HAD I NOT LOOKED OUT OF THE WINDOW AND NOTICED THIS ACFT, A COLLISION, IN MY OPINION, WOULD HAVE BEEN UNAVOIDABLE. MY DECISION TO STOP MY DSCNT TO THE RWY, IN MY MIND, HELPED TO AVOID A CATASTROPHE. I CONTACTED CTLING FACILITY AND THEY LEANED TOWARD BLAMING ACR Y FOR NOT SLOWING DOWN ON APCH. THIS WAS PROBABLY A CONTRIBUTING FACTOR, BUT WITHOUT TALKING TO THE OTHER PLT ONE CAN ONLY MAKE ASSUMPTIONS.
