MKE CTLR CONCERNED WITH MGMNT DECISION TO RESOLVE A PROB FROM A PLTDEV; WHEN A BA31 CROSSED RWY 1L IN FRONT OF A DEPARTING B727.

Narrative

THIS COM IS IN REF TO THE FAA REACTION TO A RWY INCURSION THAT OCCURRED AT MKE ON JAN/FRI/00; A BA31; AFTER ACKNOWLEDGING AN INSTRUCTION TO HOLD SHORT OF RWY 1L; CROSSED IN FRONT OF A DEPARTING B727; WHO HAD TO ROTATE EARLY TO AVOID A COLLISION. WHILE THIS WAS A HORRIBLE INCIDENT; THERE WAS NOTHING MORE THE GND CTLR COULD DO. A RECENT CHANGE TO ATC PROCS REQUIRES A READBACK OF THE HOLD SHORT INSTRUCTION. THIS WAS GIVEN. AT THIS INTXN (TXWY M AND RWY 1L); THERE ARE RECENTLY INSTALLED WIGWAG LIGHTS TO HEIGHTEN AWARENESS. IN THIS CASE; THEY DID NOT HAVE THE DESIRED RESULT. BOTTOM LINE IS THE BA31 PLT(S) SCREWED UP. IT HAPPENS. FAA RESPONSE IS TO BAN TAXIING TO RWYS E OF RWY 1L/19R WHEN RWY 1L/19R IS ACTIVE. IN ESSENCE; YOU CANNOT TRUST AN ACFT TO HOLD SHORT OF THE RWY. IT GETS WORSE; BUT THIS IS THE CRUX OF THE ISSUE. WITH DELAYS AROUND THE COUNTRY INCREASING THANKS TO THE LAHSO MESS AND PROBS WITH FLOW CTL; WE DON'T NEED ANY MORE RIDICULOUS EDICTS DELIVERED FROM ON HIGH. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR ADVISED THAT THE ORIGINAL EDICT WAS CHANGED FROM 'BANNING' TAXIING WHEN RWYS 19 WERE IN USE; TO STOPPING ACFT ON THE RAMP SHORT OF TXWY M; E OF RWY 19R WHEN RWYS 19 ARE IN USE. THE RPTR ADVISED THAT THIS RESTR STILL IS A DISTR FOR CTLR AND PLT; IMPACTING RAMP OPS FOR ANY ACFT TRYING TO TAXI VIA ANOTHER RTE TO ANOTHER RWY. THE RPTR STATED THAT TAXI INSTRUCTIONS TO RWY 25L; WITH A HOLD SHORT OF RWYS 19; IS AUTH WITH ANY OF THE OTHER 6 TXWYS INTERSECTING RWY 19R. WITH THIS EXEMPTION FOR THE OTHER TXWYS; THE RPTR BELIEVES THE RESTR FOR TXWY M IS SYMBOLIC AT BEST. THE RPTR BELIEVES A UCR HAS BEEN FILED. SUPPLEMENTAL INFO FROM ACN 460843: B727 DEPARTING RWY 1L AT MKE; ACFT X INSTRUCTED TO HOLD SHORT RWY 1L (READ BACK HOLD SHORT) CROSSED RWY 1L AT TXWY M; AS B727 PASSING V1. B727 CROSSED OVER ACFT X BY APPROX 100 FT. A CONTRIBUTING FACTOR TO THE NEAR MISS; OR IF THE AIRPLANES WOULD HAVE HIT; IS THE PROC USED BY ACRS OF REDUCED PWR ON TKOF. THE DISTANCE FROM THE DEP END OF RWY 1L TO THE INTXN OF TXWY M IS 5900 FT. THE B727 DEPARTING HAD NO PAX OR CARGO; AND THE OUTSIDE AIR TEMP WAS -18 DEGS C. IF THE B727 DIDN'T REACH V1 SPD UNTIL IT TRAVELED 5000 FT DOWN THE RWY; EVIDENCE SUGGESTS A REDUCED PWR TKOF. I RECOMMEND A STUDY TO DETERMINE THE SAFETY/COST BENEFITS OF REDUCED PWR TKOFS VERSUS FULL RATED PWR TKOFS AND HOW LONG A DEPARTING AIRPLANE REMAINS ON THE RWY. SUPPLEMENTAL INFO FROM ACN 460845: AFTER DEICING; ACFT X WAS CLRED TO TAXI TO RWY 25L VIA TXWY B AND TXWY M 'HOLD SHORT RWY 1L.' AFTER TALKING TO THE TWR SUPVR; THE HOLD SHORT WAS READ BACK BY FO. I; THE CAPT; DID NOT HEAR THE HOLD SHORT INSTRUCTIONS AND PROCEEDED TO RWY 25L. WHILE XING RWY 1L; ACFT Y WAS ON TKOF RWY 1L AND FLEW OVER OR CLOSE TO ACFT X. CREW WAS ON A CONTINUOUS DUTY OVERNIGHT AND THE INCIDENT OCCURRED AT 12+ HRS INTO THE DUTY DAY. AFTER DEICING WE HAD REDUCED VISIBILITY DUE TO GLYCOL ON THE WINDOWS. SUPPLEMENTAL INFO FROM ACN 460786: THE CAPT DID NOT HEAR THE READBACK INSTRUCTION AND PROCEEDED TO RWY 25L.
