Narrative:

Cleared for visibility approach san angelo (mathis field) runway 27. Advised to call 2 mi final. At 2 mi local controller was making radio call to another commuter aircraft (mdt) to clear him for takeoff runway 18 mathis. We advised tower that we were then 1 1/2 mi final. (Short period of confusion during which ATC controller had a hot microphone and in background heard supervisor voice saying, 'he's landing runway 27.') mdt kept on with his takeoff roll and it was obvious that we and the mdt would probably meet in the intersection of runway 18 and 27, so we initiated a go around. Controller then told the mdt to abort (or hold) and cleared us to land, but we were too high and so entered a right downwind 18. Once again problem with controller being aware of traffic in air traffic area. Trnee controllers should be closely supervised by controllers who can override them on the frequency in time critical situations.

Title: COMMUTER ACFT ON APCH AS SECOND ACFT CLEARED FOR TKOF ON INTERSECTING RWY.

Narrative: CLRED FOR VIS APCH SAN ANGELO (MATHIS FIELD) RWY 27. ADVISED TO CALL 2 MI FINAL. AT 2 MI LCL CTLR WAS MAKING RADIO CALL TO ANOTHER COMMUTER ACFT (MDT) TO CLR HIM FOR TKOF RWY 18 MATHIS. WE ADVISED TWR THAT WE WERE THEN 1 1/2 MI FINAL. (SHORT PERIOD OF CONFUSION DURING WHICH ATC CTLR HAD A HOT MIC AND IN BACKGROUND HEARD SUPVR VOICE SAYING, 'HE'S LNDG RWY 27.') MDT KEPT ON WITH HIS TKOF ROLL AND IT WAS OBVIOUS THAT WE AND THE MDT WOULD PROBABLY MEET IN THE INTXN OF RWY 18 AND 27, SO WE INITIATED A GAR. CTLR THEN TOLD THE MDT TO ABORT (OR HOLD) AND CLRED US TO LAND, BUT WE WERE TOO HIGH AND SO ENTERED A RIGHT DOWNWIND 18. ONCE AGAIN PROB WITH CTLR BEING AWARE OF TFC IN ATA. TRNEE CTLRS SHOULD BE CLOSELY SUPERVISED BY CTLRS WHO CAN OVERRIDE THEM ON THE FREQ IN TIME CRITICAL SITUATIONS.
