Narrative:
I departed the nome airport on runway 27 (active runway) for a local pleasure flight to the northeast of nome. After takeoff I turned left to make a climbing left downwind departure then a left turn to the nne. Climbing through approximately 900 ft MSL I saw an small transport just above me and to my left (my 9 O'clock position). When I saw the aircraft we were quite close but parallel, so I remained under his flight path and continued my climb since no immediate evasive action was necessary. Had I decided to turn a few seconds earlier I feel we could have hit. One of the problems contributing to this incident was the fact that I operate no-radio (it is not required since nome is uncontrolled). I think that the remedy is better pilot scanning on everyone's part. Many aircraft operate 'NORDO' out of nome, and the possibility exists for a midair collision. Better pilot vigilance is needed.

Title: NMAC IN AN UNCTLED TFC PATTERN BTWN A NORDO SMA SEL OPEN COCKPIT BIPLANE AND AN SMT TWIN ENG ACFT.
Narrative: I DEPARTED THE NOME ARPT ON RWY 27 (ACTIVE RWY) FOR A LCL PLEASURE FLT TO THE NE OF NOME. AFTER TKOF I TURNED L TO MAKE A CLBING L DOWNWIND DEP THEN A L TURN TO THE NNE. CLBING THROUGH APPROX 900 FT MSL I SAW AN SMT JUST ABOVE ME AND TO MY L (MY 9 O'CLOCK POS). WHEN I SAW THE ACFT WE WERE QUITE CLOSE BUT PARALLEL, SO I REMAINED UNDER HIS FLT PATH AND CONTINUED MY CLB SINCE NO IMMEDIATE EVASIVE ACTION WAS NECESSARY. HAD I DECIDED TO TURN A FEW SECONDS EARLIER I FEEL WE COULD HAVE HIT. ONE OF THE PROBS CONTRIBUTING TO THIS INCIDENT WAS THE FACT THAT I OPERATE NO-RADIO (IT IS NOT REQUIRED SINCE NOME IS UNCTLED). I THINK THAT THE REMEDY IS BETTER PLT SCANNING ON EVERYONE'S PART. MANY ACFT OPERATE 'NORDO' OUT OF NOME, AND THE POSSIBILITY EXISTS FOR A MIDAIR COLLISION. BETTER PLT VIGILANCE IS NEEDED.
