Reporter alleges a new crossing restr on the masty STAR forces turbojet arrs below 10000 ft outside ...

Narrative:

Dfw TRACON implemented a new crossing restr associated with the masty STAR at dfw airport. This procedure forces dfw turbojet arrs down to 9000 ft 44 mi northwest of the airport at gregs intersection. This is outside class B airspace and below 10000 ft MSL where there is no requirement for a transponder or mode C altitude reporting. It is also outside the 30 NM mode C veil. Forcing turbojet or any TCASII equipped aircraft into this airspace is asking for another cerritos incident. Dfw is a busy terminal which does not allow overflt traffic therefore all traffic is forced to go around. Many of these aircraft utilize a route which puts them in direct conflict with the masty STAR. If we don't stop descending aircraft below 10000 ft outside class B airspace it is only a matter of time before a midair collision will occur around gregs intersection because TCASII is ineffective with non mode C aircraft. The previously agreed upon crossing restr, cross gregs at 11000 ft, posed no safety risk to the flying public and should be re-implemented, immediately. I have previously filed an unsatisfactory condition report on this procedure which was supported by my immediate supervisor but has not been acted on at the next higher level. This is a serious liability and safety risk and must not be ignored. Callback conversation with reporter revealed the following information: reporter indicated concern for the turbojet exposure to traffic below 10000 ft that may not be visible to the acrs. Reporter stated the altitude crossing change was made by dfw personnel for arrival flow to runway 13 at dfw and away from the traffic using the parallel runways. Reporter indicated he has the support of his immediate supervisor for filing the ucr. Reporter alleges dfw personnel refuse to change the crossing altitude back to the original 11000 ft. Reporter stated he has not heard of any incidents involving acrs and GA aircraft in the area of concern.

Title: RPTR ALLEGES A NEW XING RESTR ON THE MASTY STAR FORCES TURBOJET ARRS BELOW 10000 FT OUTSIDE CLASS B AIRSPACE AND INTO AN AREA WHERE THERE IS NO REQUIREMENT FOR XPONDER OR MODE C ALT RPTING.

Narrative: DFW TRACON IMPLEMENTED A NEW XING RESTR ASSOCIATED WITH THE MASTY STAR AT DFW ARPT. THIS PROC FORCES DFW TURBOJET ARRS DOWN TO 9000 FT 44 MI NW OF THE ARPT AT GREGS INTXN. THIS IS OUTSIDE CLASS B AIRSPACE AND BELOW 10000 FT MSL WHERE THERE IS NO REQUIREMENT FOR A XPONDER OR MODE C ALT RPTING. IT IS ALSO OUTSIDE THE 30 NM MODE C VEIL. FORCING TURBOJET OR ANY TCASII EQUIPPED ACFT INTO THIS AIRSPACE IS ASKING FOR ANOTHER CERRITOS INCIDENT. DFW IS A BUSY TERMINAL WHICH DOES NOT ALLOW OVERFLT TFC THEREFORE ALL TFC IS FORCED TO GO AROUND. MANY OF THESE ACFT UTILIZE A RTE WHICH PUTS THEM IN DIRECT CONFLICT WITH THE MASTY STAR. IF WE DON'T STOP DSNDING ACFT BELOW 10000 FT OUTSIDE CLASS B AIRSPACE IT IS ONLY A MATTER OF TIME BEFORE A MIDAIR COLLISION WILL OCCUR AROUND GREGS INTXN BECAUSE TCASII IS INEFFECTIVE WITH NON MODE C ACFT. THE PREVIOUSLY AGREED UPON XING RESTR, CROSS GREGS AT 11000 FT, POSED NO SAFETY RISK TO THE FLYING PUBLIC AND SHOULD BE RE-IMPLEMENTED, IMMEDIATELY. I HAVE PREVIOUSLY FILED AN UNSATISFACTORY CONDITION RPT ON THIS PROC WHICH WAS SUPPORTED BY MY IMMEDIATE SUPVR BUT HAS NOT BEEN ACTED ON AT THE NEXT HIGHER LEVEL. THIS IS A SERIOUS LIABILITY AND SAFETY RISK AND MUST NOT BE IGNORED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR INDICATED CONCERN FOR THE TURBOJET EXPOSURE TO TFC BELOW 10000 FT THAT MAY NOT BE VISIBLE TO THE ACRS. RPTR STATED THE ALT XING CHANGE WAS MADE BY DFW PERSONNEL FOR ARR FLOW TO RWY 13 AT DFW AND AWAY FROM THE TFC USING THE PARALLEL RWYS. RPTR INDICATED HE HAS THE SUPPORT OF HIS IMMEDIATE SUPVR FOR FILING THE UCR. RPTR ALLEGES DFW PERSONNEL REFUSE TO CHANGE THE XING ALT BACK TO THE ORIGINAL 11000 FT. RPTR STATED HE HAS NOT HEARD OF ANY INCIDENTS INVOLVING ACRS AND GA ACFT IN THE AREA OF CONCERN.
