Narrative:

After takeoff, I made a left 360 degrees to make a low pass. After the low pass, I made a climbing left turn when tustin tower informed me of 3 aircraft at my 12 O'clock position, that were landing at john wayne (sna). I had no time to reduce power. My only option was to lower my nose and pass under the other aircraft. The end result was that I was very low over a tract of homes, at high power and was moving quite fast (200 KTS). I do not know if the 3 aircraft had strayed further north in their landing pattern or this was a normal position for them. If this was a normal position, then tustin tower should have coordinated their activities with sna tower better. Callback conversation with reporter revealed the following information: reporter states he was departing to the southwest. His low pass was coordinated with the tower. The traffic landing at sna was using runway 19L. He has done formation flying and the first thing one learns is not ever to turn your belly to the other aircraft. There was no way reporter could turn without doing so. He felt his descent was the only way to avoid contact. It happened in a split second and he had his hand on the throttle but could not look away to check mp. Reporter indicated that tustin tower usually does an excellent job of coordinating with the sna traffic and he has not had problems previously. No FAA follow up or comment from tustin tower controllers.

Title: T28 HAS NMAC WITH ACRS ON APCH TO SNA. EVASIVE ACTION.

Narrative: AFTER TKOF, I MADE A L 360 DEGS TO MAKE A LOW PASS. AFTER THE LOW PASS, I MADE A CLBING L TURN WHEN TUSTIN TWR INFORMED ME OF 3 ACFT AT MY 12 O'CLOCK POS, THAT WERE LNDG AT JOHN WAYNE (SNA). I HAD NO TIME TO REDUCE PWR. MY ONLY OPTION WAS TO LOWER MY NOSE AND PASS UNDER THE OTHER ACFT. THE END RESULT WAS THAT I WAS VERY LOW OVER A TRACT OF HOMES, AT HIGH PWR AND WAS MOVING QUITE FAST (200 KTS). I DO NOT KNOW IF THE 3 ACFT HAD STRAYED FURTHER N IN THEIR LNDG PATTERN OR THIS WAS A NORMAL POS FOR THEM. IF THIS WAS A NORMAL POS, THEN TUSTIN TWR SHOULD HAVE COORDINATED THEIR ACTIVITIES WITH SNA TWR BETTER. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES HE WAS DEPARTING TO THE SW. HIS LOW PASS WAS COORDINATED WITH THE TWR. THE TFC LNDG AT SNA WAS USING RWY 19L. HE HAS DONE FORMATION FLYING AND THE FIRST THING ONE LEARNS IS NOT EVER TO TURN YOUR BELLY TO THE OTHER ACFT. THERE WAS NO WAY RPTR COULD TURN WITHOUT DOING SO. HE FELT HIS DSCNT WAS THE ONLY WAY TO AVOID CONTACT. IT HAPPENED IN A SPLIT SECOND AND HE HAD HIS HAND ON THE THROTTLE BUT COULD NOT LOOK AWAY TO CHK MP. RPTR INDICATED THAT TUSTIN TWR USUALLY DOES AN EXCELLENT JOB OF COORDINATING WITH THE SNA TFC AND HE HAS NOT HAD PROBS PREVIOUSLY. NO FAA FOLLOW UP OR COMMENT FROM TUSTIN TWR CTLRS.
