Narrative

MSY GND CLRED US TO TAXI TO RWY 19 VIA TXWY S. AS WE APCHED A CONSTRUCTION AREA ABEAM CONCOURSE GATE; A B737 WAS TOLD TO MOVE TO THE R AND HOLD FOR A B727 THEN TAXI TO GATE. ACR Y SAID 'IT'S OK; WE CAN MAKE IT.' B737 CONTINUED TO TAXI; IN VIOLATION OF ITS CLRNC. IT WAS APPARENT B737 WAS NOT GOING TO STOP; SO I HAD TO ABRUPTLY STOP ACFT; SET PARKING BRAKE AND WAIT. THERE WAS NOT ENOUGH ROOM FOR 2 ACFT TO PASS IN THIS CONSTRUCTION AREA. IN FACT; WE STOPPED 25 FT SHORT OF THE NARROWEST AREA SO AS TO NOT COLLIDE WITH ACR Y. ACR Y TURNED TOWARD US; THEN THEY TURNED AWAY. THE B737 TAXIED INTO A NON MOVEMENT AREA WITH HIS WING OVER A CONSTRUCTION FENCE. HAD WE NOT STOPPED WE WOULD HAVE HAD AN ACCIDENT. REAL CAUSE: AIRLINE Y'S TAXIING TOO FAST. THEY VIOLATED AN ATC CLRNC. SOLUTION: MONITOR ACR Y TAXI PROCS. SOME DAY WE ARE GOING TO HAVE A SERIOUS PROB WHEN ACR Y HAS A GND ACCIDENT IF NOTHING IS DONE ABOUT THEIR TAXI TECHNIQUES. SOLUTION TO THIS ONE: VIOLATE ACR Y FOR VIOLATING A CLRNC AND ENDANGERING 143 PAX AND 7 CREW MEMBERS ON MY FLT; ALONG WITH PAX AND CREW OF ACR Y ACFT.
