ACR TAKES TAXI CLRNC MEANT FOR ANOTHER ACFT. CTLR RPTR CRITICAL OF PLT RADIO TECHNIQUE. NON INCIDENT.

Narrative

INCIDENT OCCURRED ON GND CTL FREQ. ATX X; AN LTT; CALLED GND CTL FREQ AND REQUESTED TAXI CLRNC. RWY 04 WAS IN USE AND ATX X WAS TOLD 'ATX X; RWY 4 HOLD SHORT OF RWY ONE- ZERO.' BEFORE ATX X COULD RESPOND AND IMMEDIATELY AFTER GND CTL UNKEYED THE MIKE; ACR Y; AN MLG; CALLED FOR TAXI CLRNC. BEFORE GND CTL COULD RESPOND TO ACR Y; ATX X READBACK HIS CLRNC WITH NO IDENT AS FOLLOWS: 'RWY 4 HOLD SHORT OF 10.' GND CTL THEN TOLD ACR Y THAT HE READBACK A CLRNC THAT WAS NOT ISSUED BY GND CTL BUT RATHER A READBACK FROM ANOTHER ACFT. ATX X WAS ASKED BY GND CTL TO CONFIRM THAT HE HAD UNDERSTOOD HIS CLRNC. PRIMARY CAUSE OF THE SITUATION WAS THE FAILURE OF ATX X TO ACKNOWLEDGE HIS CLRNC USING HIS CALL SIGN. SECONDARY CAUSE WAS FAILURE OF ACR Y TO PROPERLY MONITOR THE FREQ PRIOR TO XMITTING TO MAKE SURE IT WAS CLR; AND ALSO ACR Y ACCEPTING A CLRNC BROADCAST FROM AN UNKNOWN AND UNIDENTED SOURCE. THIS RPTR HAS NOTICED A SHARP INCREASE LATELY IN IMPROPER RADIO COMS; MOSTLY BY PLTS OF REGIONAL COMMUTER AIRLINES. THEY MAKE A ROUTINE PRACTICE OF OMITTING THE COMPANY NAME AND JUST USE THE FLT NUMBER; OR OMIT THE CALL SIGN ENTIRELY. ALSO; I HAVE NOTICED THAT MANY AIR CARRIER PLTS SEEM TO BE IN A RUSH MORE THAN USUAL AND OFTEN BLOCK XMISSION WITH THEIR OWN BECAUSE THEY DON'T MONITOR THE FREQ BEFORE THEY XMIT. CTLRS ALSO CONTRIBUTE TO THE PROBLEM; ESPECIALLY AT LARGER ARPTS; BY USING IMPROPER PHRASEOLOGY. PLTS HAVE BECOME USED TO ACCEPTING CLRNCS WITHOUT PROPER FACILITY AND POS IDENT. SOLUTION: REINSTITUTE THE PROGRAM 'CALL TO ACTION' TO INCREASE PLT- CTLR AWARENESS OF CORRECT PHRASEOLOGY TO REDUCE MISUNDERSTOOD COMS.
