Narrative:

During departure from sps (sheppard air base/wichita falls municipal) airport while flying on departure clearance (after departure turn left, heading 280 degrees, climb and maintain 2300', expect 7000' 5 mins). Since surface winds 010 degrees at 20 KTS, both 35 and 33L and right were in use. Runway 35 for civilian runways 33L and right for military traffic. This was the first officer's leg (PF) and I was captain (PNF). Flying our clearance after takeoff after flap and gear retraction and climbing through 1900' MSL I saw an MTR at 1 O'clock, same altitude, opp direction. He was in right traffic pattern for 33L. As I was calling traffic to the first officer I initiated a descent to about 1800' while in the left turn to 280 degrees. As the MTR was passing overhead the local tower controller called, 'traffic at 1 O'clock, less than a mile, MTR same altitude.' too late. We had taken evasive action already and avoided the MTR. The rest of the flight was uneventful. This situation occurs too frequently at sheppard. It seems that the trnee pilots (MTR) cannot hold altitude on their downwind leg (should be 2800' at that position).

Title: CLOSE ENCOUNTER DEPARTING TRAFFIC PATTERN.

Narrative: DURING DEP FROM SPS (SHEPPARD AIR BASE/WICHITA FALLS MUNI) ARPT WHILE FLYING ON DEP CLRNC (AFTER DEP TURN LEFT, HDG 280 DEGS, CLB AND MAINTAIN 2300', EXPECT 7000' 5 MINS). SINCE SURFACE WINDS 010 DEGS AT 20 KTS, BOTH 35 AND 33L AND R WERE IN USE. RWY 35 FOR CIVILIAN RWYS 33L AND R FOR MIL TFC. THIS WAS THE F/O'S LEG (PF) AND I WAS CAPT (PNF). FLYING OUR CLRNC AFTER TKOF AFTER FLAP AND GEAR RETRACTION AND CLBING THROUGH 1900' MSL I SAW AN MTR AT 1 O'CLOCK, SAME ALT, OPP DIRECTION. HE WAS IN RIGHT TFC PATTERN FOR 33L. AS I WAS CALLING TFC TO THE F/O I INITIATED A DSCNT TO ABOUT 1800' WHILE IN THE LEFT TURN TO 280 DEGS. AS THE MTR WAS PASSING OVERHEAD THE LCL TWR CTLR CALLED, 'TFC AT 1 O'CLOCK, LESS THAN A MILE, MTR SAME ALT.' TOO LATE. WE HAD TAKEN EVASIVE ACTION ALREADY AND AVOIDED THE MTR. THE REST OF THE FLT WAS UNEVENTFUL. THIS SITUATION OCCURS TOO FREQUENTLY AT SHEPPARD. IT SEEMS THAT THE TRNEE PLTS (MTR) CANNOT HOLD ALT ON THEIR DOWNWIND LEG (SHOULD BE 2800' AT THAT POS).
