Narrative:

Landing runway 25L at phx. Tower had cleared us to cross runway 25R at taxiway F8 and stay with him to the gate. As we crossed taxiway D we had a near collision with a turboprop twin who appeared out of nowhere. I had just previously cleared to my left to determine the best entry point. About 30 seconds later all I saw was a flash in my left peripheral vision and locked up the brakes. The twin had to do the same and veer left. He ended up in front of my wing. Taxiway D is actually part of the ramp area at this point and the twin was taxiing in excess of 30 mph versus the 'brisk walk' maximum per the far's. The twin was on ground frequency so we could not communicate nor did we have any situational awareness of our surroundings per radios. Does tower and ground not have ground radar for this very reason? Supplemental information from acn 722226: normal landing runway 25L in phx. Held short of runway 25R. When tower cleared us to cross runway 25R. They said cleared to cross runway 25R and cleared to taxi to park with them. When clearing runway 25R it takes about a 90 degree right turn on taxiway east then a 90 degree left turn into the ramp area; crossing taxiway; this point. Just as the captain was completing the second 90 degree turn; he had to very aggressively apply the brakes to avoid a collision with a small 2 engine turboprop aircraft. The turboprop also aggressively stopped. The turboprop was taxiing west to east on taxiway D; and apparently was on ground control frequency while we were still with tower. There was no collision nor were there any injuries.

Title: MD80 NEARLY COLLIDES WITH TURBO PROP TWIN WHILE TAXIING TO GATE AT PHX.

Narrative: LNDG RWY 25L AT PHX. TWR HAD CLRED US TO CROSS RWY 25R AT TXWY F8 AND STAY WITH HIM TO THE GATE. AS WE CROSSED TXWY D WE HAD A NEAR COLLISION WITH A TURBOPROP TWIN WHO APPEARED OUT OF NOWHERE. I HAD JUST PREVIOUSLY CLRED TO MY L TO DETERMINE THE BEST ENTRY POINT. ABOUT 30 SECONDS LATER ALL I SAW WAS A FLASH IN MY L PERIPHERAL VISION AND LOCKED UP THE BRAKES. THE TWIN HAD TO DO THE SAME AND VEER L. HE ENDED UP IN FRONT OF MY WING. TXWY D IS ACTUALLY PART OF THE RAMP AREA AT THIS POINT AND THE TWIN WAS TAXIING IN EXCESS OF 30 MPH VERSUS THE 'BRISK WALK' MAX PER THE FAR'S. THE TWIN WAS ON GND FREQ SO WE COULD NOT COMMUNICATE NOR DID WE HAVE ANY SITUATIONAL AWARENESS OF OUR SURROUNDINGS PER RADIOS. DOES TWR AND GND NOT HAVE GND RADAR FOR THIS VERY REASON? SUPPLEMENTAL INFO FROM ACN 722226: NORMAL LNDG RWY 25L IN PHX. HELD SHORT OF RWY 25R. WHEN TWR CLRED US TO CROSS RWY 25R. THEY SAID CLRED TO CROSS RWY 25R AND CLRED TO TAXI TO PARK WITH THEM. WHEN CLRING RWY 25R IT TAKES ABOUT A 90 DEG R TURN ON TXWY E THEN A 90 DEG L TURN INTO THE RAMP AREA; XING TXWY; THIS POINT. JUST AS THE CAPT WAS COMPLETING THE SECOND 90 DEG TURN; HE HAD TO VERY AGGRESSIVELY APPLY THE BRAKES TO AVOID A COLLISION WITH A SMALL 2 ENG TURBOPROP ACFT. THE TURBOPROP ALSO AGGRESSIVELY STOPPED. THE TURBOPROP WAS TAXIING W TO E ON TXWY D; AND APPARENTLY WAS ON GND CTL FREQ WHILE WE WERE STILL WITH TWR. THERE WAS NO COLLISION NOR WERE THERE ANY INJURIES.
