Narrative:

3/90 at terre haute, in the following near miss occurred. Army guard mlt assigned to the indiana army national guard was operating on an INS flight plan and was cleared for an ILS runway 5 approach. Guard was 2200' MSL, and was approximately 1 1/2 mi outside yinno, the OM for the approach. At that time the pilot in the right seat, who was not flying, noticed an airplane approaching from the 2 O'clock position, slightly higher and in a right-hand turn toward the mlt and descending. The mlt was forced to make an abrupt diving left evasive maneuver to avoid the conflicting aircraft, which was an fgt assigned to the indiana air national guard. The fgt continued descending and made a low pass over the airport. The mlt went on to land on runway. An FAA near miss report was filed with the FAA tower supervisor at the terre haute airport. A student controller was working approach control and a newly certified tower controller was on duty at the time of the incident. The fgt working tower and the mlt was on approach control. The tower controller stated that he had not advised the mlt of the position of the fgt, however the fgt had strayed farther outside the traffic pattern than the tower controller had anticipated, therefore he saw no reason to call the fgt traffic. When the fgt pilot was contacted immediately after the incident, he stated that he saw the mlt about 1 mi away, but did not consider evasive action. It has been my experience that terre haute has extensive military training activity 7 days a week. Coupled with the usual corp and civilian training activities at the airport, it seems that these controllers are overloaded. The use of VHF and UHF radios adds to the confusion. At a minimum changes need to be made in the way these high speed aircraft are accepted into the flow of traffic.

Title: CLOSE PROX MLT FGT AT HUF.

Narrative: 3/90 AT TERRE HAUTE, IN THE FOLLOWING NEAR MISS OCCURRED. ARMY GUARD MLT ASSIGNED TO THE INDIANA ARMY NATL GUARD WAS OPERATING ON AN INS FLT PLAN AND WAS CLRED FOR AN ILS RWY 5 APCH. GUARD WAS 2200' MSL, AND WAS APPROX 1 1/2 MI OUTSIDE YINNO, THE OM FOR THE APCH. AT THAT TIME THE PLT IN THE RIGHT SEAT, WHO WAS NOT FLYING, NOTICED AN AIRPLANE APCHING FROM THE 2 O'CLOCK POS, SLIGHTLY HIGHER AND IN A RIGHT-HAND TURN TOWARD THE MLT AND DSNDING. THE MLT WAS FORCED TO MAKE AN ABRUPT DIVING LEFT EVASIVE MANEUVER TO AVOID THE CONFLICTING ACFT, WHICH WAS AN FGT ASSIGNED TO THE INDIANA AIR NATL GUARD. THE FGT CONTINUED DSNDING AND MADE A LOW PASS OVER THE ARPT. THE MLT WENT ON TO LAND ON RWY. AN FAA NEAR MISS RPT WAS FILED WITH THE FAA TWR SUPVR AT THE TERRE HAUTE ARPT. A STUDENT CTLR WAS WORKING APCH CTL AND A NEWLY CERTIFIED TWR CTLR WAS ON DUTY AT THE TIME OF THE INCIDENT. THE FGT WORKING TWR AND THE MLT WAS ON APCH CTL. THE TWR CTLR STATED THAT HE HAD NOT ADVISED THE MLT OF THE POS OF THE FGT, HOWEVER THE FGT HAD STRAYED FARTHER OUTSIDE THE TFC PATTERN THAN THE TWR CTLR HAD ANTICIPATED, THEREFORE HE SAW NO REASON TO CALL THE FGT TFC. WHEN THE FGT PLT WAS CONTACTED IMMEDIATELY AFTER THE INCIDENT, HE STATED THAT HE SAW THE MLT ABOUT 1 MI AWAY, BUT DID NOT CONSIDER EVASIVE ACTION. IT HAS BEEN MY EXPERIENCE THAT TERRE HAUTE HAS EXTENSIVE MIL TRNING ACTIVITY 7 DAYS A WK. COUPLED WITH THE USUAL CORP AND CIVILIAN TRNING ACTIVITIES AT THE ARPT, IT SEEMS THAT THESE CTLRS ARE OVERLOADED. THE USE OF VHF AND UHF RADIOS ADDS TO THE CONFUSION. AT A MINIMUM CHANGES NEED TO BE MADE IN THE WAY THESE HIGH SPD ACFT ARE ACCEPTED INTO THE FLOW OF TFC.
