Narrative:

I was busy picking up ATIS and doing my in-range checklist, so I was distracted for several moments from doing my outside visual scan. From the time I looked away to the time I continued my scan, a fast-moving multi-engine seaplane had appeared off my front left side. I was northbound off the coast and underneath mia's class B. The other aircraft was eastbound at the same altitude. I took immediate evasive action -- a descending 60 degree left turn. The other pilot never changed course or altitude. The problem arose because neither pilot was exercising good 'see and avoid' visual scanning techniques. Fortunately, I discovered the conflict before it was too late. The problem can be corrected by increased visual scanning rates and techniques, not focusing for too long on tasks which take away from scanning while in VMC, and exercising better situational awareness.

Original NASA ASRS Text

Title: NMAC BY ATX PLT WITH XING SAME ALT TFC IN PROX OF TCA B AIRSPACE.

Narrative: I WAS BUSY PICKING UP ATIS AND DOING MY IN-RANGE CHKLIST, SO I WAS DISTRACTED FOR SEVERAL MOMENTS FROM DOING MY OUTSIDE VISUAL SCAN. FROM THE TIME I LOOKED AWAY TO THE TIME I CONTINUED MY SCAN, A FAST-MOVING MULTI-ENG SEAPLANE HAD APPEARED OFF MY FRONT L SIDE. I WAS NBOUND OFF THE COAST AND UNDERNEATH MIA'S CLASS B. THE OTHER ACFT WAS EBOUND AT THE SAME ALT. I TOOK IMMEDIATE EVASIVE ACTION -- A DSNDING 60 DEG L TURN. THE OTHER PLT NEVER CHANGED COURSE OR ALT. THE PROB AROSE BECAUSE NEITHER PLT WAS EXERCISING GOOD 'SEE AND AVOID' VISUAL SCANNING TECHNIQUES. FORTUNATELY, I DISCOVERED THE CONFLICT BEFORE IT WAS TOO LATE. THE PROB CAN BE CORRECTED BY INCREASED VISUAL SCANNING RATES AND TECHNIQUES, NOT FOCUSING FOR TOO LONG ON TASKS WHICH TAKE AWAY FROM SCANNING WHILE IN VMC, AND EXERCISING BETTER SITUATIONAL AWARENESS.
