Narrative:

I, in small aircraft X, was taking off to do a touch and go. The other plane, small aircraft Y, announced it was downwind and requested advisories. The unicom operator said there was local traffic. I was in the air flying the runway heading before turning crosswind and looking for the downwind plane ahead and to my left. Nothing. I started the crosswind turn and was looking to see if he was entering at mid field. He was turning to his right and I did a descending turn to my right. I should have extended my flight along the runway heading and asked where he was (neither of us communicated) and not turned till I saw him. I don't believe he had his landing light on which might have helped me see him. My landing lights was on. I had announced on final that I was touch and go, but it might have helped to say I was doing a touch and go as I was taking off.

Title: NMAC BETWEEN 2 SMA'S AT SFM IN TRAFFIC PATTERN.

Narrative: I, IN SMA X, WAS TAKING OFF TO DO A TOUCH AND GO. THE OTHER PLANE, SMA Y, ANNOUNCED IT WAS DOWNWIND AND REQUESTED ADVISORIES. THE UNICOM OPERATOR SAID THERE WAS LCL TFC. I WAS IN THE AIR FLYING THE RWY HDG BEFORE TURNING XWIND AND LOOKING FOR THE DOWNWIND PLANE AHEAD AND TO MY LEFT. NOTHING. I STARTED THE XWIND TURN AND WAS LOOKING TO SEE IF HE WAS ENTERING AT MID FIELD. HE WAS TURNING TO HIS RIGHT AND I DID A DSNDING TURN TO MY RIGHT. I SHOULD HAVE EXTENDED MY FLT ALONG THE RWY HDG AND ASKED WHERE HE WAS (NEITHER OF US COMMUNICATED) AND NOT TURNED TILL I SAW HIM. I DON'T BELIEVE HE HAD HIS LNDG LIGHT ON WHICH MIGHT HAVE HELPED ME SEE HIM. MY LNDG LIGHTS WAS ON. I HAD ANNOUNCED ON FINAL THAT I WAS TOUCH AND GO, BUT IT MIGHT HAVE HELPED TO SAY I WAS DOING A TOUCH AND GO AS I WAS TAKING OFF.
