Narrative:

Flight of 2 T45 trainers crossed the kings 1 MOA southern boundary. Kingsville approach attempted radio warning with no transmission heard by lead or wing regarding MOA spill out. PIC notified after landing that got dangerously close to civil aircraft and lrd 128 degree radial, 23 DME. Told civil aircraft saw T45 aircraft, took evasive action (descent). This is simply pilot error. Some type of warning transmission that can be heard by aircraft in that location would be helpful. Neither lead nor wing were aware of any potential conflict with another aircraft until after landing. I believe several warning xmissions were made, but could not be heard due to lack of power in the kingsville approach control radio transmitters. Contributing factors (albeit small) were WX, twring cumulus, and student solo as wingman.

Original NASA ASRS Text

Title: FLT OF 2 MIL T45 ACFT HAD SPILLOUT FROM MOA AND HAD NMAC WITH PA28.

Narrative: FLT OF 2 T45 TRAINERS CROSSED THE KINGS 1 MOA SOUTHERN BOUNDARY. KINGSVILLE APCH ATTEMPTED RADIO WARNING WITH NO XMISSION HEARD BY LEAD OR WING REGARDING MOA SPILL OUT. PIC NOTIFIED AFTER LNDG THAT GOT DANGEROUSLY CLOSE TO CIVIL ACFT AND LRD 128 DEG RADIAL, 23 DME. TOLD CIVIL ACFT SAW T45 ACFT, TOOK EVASIVE ACTION (DSCNT). THIS IS SIMPLY PLT ERROR. SOME TYPE OF WARNING XMISSION THAT CAN BE HEARD BY ACFT IN THAT LOCATION WOULD BE HELPFUL. NEITHER LEAD NOR WING WERE AWARE OF ANY POTENTIAL CONFLICT WITH ANOTHER ACFT UNTIL AFTER LNDG. I BELIEVE SEVERAL WARNING XMISSIONS WERE MADE, BUT COULD NOT BE HEARD DUE TO LACK OF PWR IN THE KINGSVILLE APCH CTL RADIO XMITTERS. CONTRIBUTING FACTORS (ALBEIT SMALL) WERE WX, TWRING CUMULUS, AND STUDENT SOLO AS WINGMAN.
