Narrative:

After going around the pattern with a local CFI flying my airplane, I dropped him on the ramp, radioed that I was departing runway 25, and I took off. I climbed with reduced power (for noise abatement) staying in the pattern turning crosswind and downwind, reporting the downwind. About 3/4 of the way down the runway I made another left turn, thus flying across the runway and the ramp. This turn was not reported. As I crossed the ramp I waved to my instructor and increased the angle of climb. At this point, I was flying on a heading of about 320 degrees plus or minus. The glare of the sun on my windshield made it difficult for me to see in the area to my left and straight ahead. Suddenly, yellow and white small aircraft appeared in my windshield. I dove beneath him and tried to call him on the unicom frequency. He did not acknowledge my call. I turned to a westerly heading and watched him land on runway 25 and taxi to the ramp (without communication). I felt that a confrontation at this point would be meaningless, so I departed the area and flew home. It turned out that there were 2 people in the small aircraft (a student and a CFI). This incident was clear cut failure to 'see and avoid,' and 'to communication position at an uncontrolled airport.' both pilots were lax and lucky.

Title: NMAC IN TFC PATTERN OVER A NON CTLED ARPT BTWN 2 SMA SINGLE ENG LAND ACFT. BOTH ACFT WERE NOT FLYING THE RECOMMENDED PROC FOR DEPARTING OR ENTERING THE PATTERN. 1 ACFT WAS USING UNICOM.

Narrative: AFTER GOING AROUND THE PATTERN WITH A LCL CFI FLYING MY AIRPLANE, I DROPPED HIM ON THE RAMP, RADIOED THAT I WAS DEPARTING RWY 25, AND I TOOK OFF. I CLBED WITH REDUCED PWR (FOR NOISE ABATEMENT) STAYING IN THE PATTERN TURNING XWIND AND DOWNWIND, RPTING THE DOWNWIND. ABOUT 3/4 OF THE WAY DOWN THE RWY I MADE ANOTHER L TURN, THUS FLYING ACROSS THE RWY AND THE RAMP. THIS TURN WAS NOT RPTED. AS I CROSSED THE RAMP I WAVED TO MY INSTRUCTOR AND INCREASED THE ANGLE OF CLB. AT THIS POINT, I WAS FLYING ON A HDG OF ABOUT 320 DEGS PLUS OR MINUS. THE GLARE OF THE SUN ON MY WINDSHIELD MADE IT DIFFICULT FOR ME TO SEE IN THE AREA TO MY L AND STRAIGHT AHEAD. SUDDENLY, YELLOW AND WHITE SMA APPEARED IN MY WINDSHIELD. I DOVE BENEATH HIM AND TRIED TO CALL HIM ON THE UNICOM FREQ. HE DID NOT ACKNOWLEDGE MY CALL. I TURNED TO A WESTERLY HDG AND WATCHED HIM LAND ON RWY 25 AND TAXI TO THE RAMP (WITHOUT COM). I FELT THAT A CONFRONTATION AT THIS POINT WOULD BE MEANINGLESS, SO I DEPARTED THE AREA AND FLEW HOME. IT TURNED OUT THAT THERE WERE 2 PEOPLE IN THE SMA (A STUDENT AND A CFI). THIS INCIDENT WAS CLR CUT FAILURE TO 'SEE AND AVOID,' AND 'TO COM POS AT AN UNCTLED ARPT.' BOTH PLTS WERE LAX AND LUCKY.
