Narrative:

Announced 'santa paula traffic -- taking runway for takeoff.' on climb out, immediately after turn to crosswind, blue and white high wing aerobatic passed below, behind to the downwind. I turned downwind behind and to left of other aircraft, proceeded past approach end and departed pattern. Other aircraft landed. I did not see other aircraft until we passed. High wing versus low wing and my climb attitude may have contributed. Did not hear other pilot call base or final, possibly no working radio. For me, more vigilance in order when turning crosswind. Topography at santa paula does not permit 45 degree entry to downwind leg. Long downwind is the prescribed approach from northeast. Those making such approachs should be especially watchful for crosswind turners. For future runway 4 takeoffs, I may choose to depart straight out.

Title: SMA IN TFC PATTERN AND ANOTHER SMA ENTERING PATTERN HAVE NMAC.

Narrative: ANNOUNCED 'SANTA PAULA TFC -- TAKING RWY FOR TKOF.' ON CLBOUT, IMMEDIATELY AFTER TURN TO XWIND, BLUE AND WHITE HIGH WING AEROBATIC PASSED BELOW, BEHIND TO THE DOWNWIND. I TURNED DOWNWIND BEHIND AND TO L OF OTHER ACFT, PROCEEDED PAST APCH END AND DEPARTED PATTERN. OTHER ACFT LANDED. I DID NOT SEE OTHER ACFT UNTIL WE PASSED. HIGH WING VERSUS LOW WING AND MY CLB ATTITUDE MAY HAVE CONTRIBUTED. DID NOT HEAR OTHER PLT CALL BASE OR FINAL, POSSIBLY NO WORKING RADIO. FOR ME, MORE VIGILANCE IN ORDER WHEN TURNING XWIND. TOPOGRAPHY AT SANTA PAULA DOES NOT PERMIT 45 DEG ENTRY TO DOWNWIND LEG. LONG DOWNWIND IS THE PRESCRIBED APCH FROM NE. THOSE MAKING SUCH APCHS SHOULD BE ESPECIALLY WATCHFUL FOR XWIND TURNERS. FOR FUTURE RWY 4 TKOFS, I MAY CHOOSE TO DEPART STRAIGHT OUT.
