Narrative:

I was #1 for takeoff at runway 32 at boire airport in nashua, nh. An small aircraft X reported entering left base for a landing on runway 32. I addressed the small aircraft X on the unicom frequency and advised that I would take the active for takeoff before he turned to his final leg. The small aircraft X pilot then cut the corner and turned toward the runway on a modified base/final or circular pattern and he advised over the radio that he wouldn't advise it because he was going to 'cut it close.' as I was already on the runway, I began my takeoff run and executed the takeoff and left the area. The small aircraft X executed a go around. The premature turn to final by the small aircraft X was a clear attempt to establish a right of way in favor of that pilot. Had he executed a rectangular pattern, there would have been ample time to execute a safe takeoff west/O any conflict. I would suggest more education and enforcement in the area of executing rectangular traffic patterns at uncontrolled airports. I have observed several other traffic conflicts between uncontrolled airport regulars who tend to fly very close, non rectangular patterns, and pilot unfamiliar with the airport who tend to fly by the book owing to less familiarity with the terrain.

Title: NON TWR ARPT REPORTER ADVISED ON UNICOM WOULD BE DEPARTING BEFORE LNDG ACFT WOULD BE ON FINAL. LNDG ACFT MADE SHORT APCH RESULTING IN A GO AROUND.

Narrative: I WAS #1 FOR TKOF AT RWY 32 AT BOIRE ARPT IN NASHUA, NH. AN SMA X RPTED ENTERING LEFT BASE FOR A LNDG ON RWY 32. I ADDRESSED THE SMA X ON THE UNICOM FREQ AND ADVISED THAT I WOULD TAKE THE ACTIVE FOR TKOF BEFORE HE TURNED TO HIS FINAL LEG. THE SMA X PLT THEN CUT THE CORNER AND TURNED TOWARD THE RWY ON A MODIFIED BASE/FINAL OR CIRCULAR PATTERN AND HE ADVISED OVER THE RADIO THAT HE WOULDN'T ADVISE IT BECAUSE HE WAS GOING TO 'CUT IT CLOSE.' AS I WAS ALREADY ON THE RWY, I BEGAN MY TKOF RUN AND EXECUTED THE TKOF AND LEFT THE AREA. THE SMA X EXECUTED A GO AROUND. THE PREMATURE TURN TO FINAL BY THE SMA X WAS A CLEAR ATTEMPT TO ESTABLISH A RIGHT OF WAY IN FAVOR OF THAT PLT. HAD HE EXECUTED A RECTANGULAR PATTERN, THERE WOULD HAVE BEEN AMPLE TIME TO EXECUTE A SAFE TKOF W/O ANY CONFLICT. I WOULD SUGGEST MORE EDUCATION AND ENFORCEMENT IN THE AREA OF EXECUTING RECTANGULAR TFC PATTERNS AT UNCTLED ARPTS. I HAVE OBSERVED SEVERAL OTHER TFC CONFLICTS BTWN UNCTLED ARPT REGULARS WHO TEND TO FLY VERY CLOSE, NON RECTANGULAR PATTERNS, AND PLT UNFAMILIAR WITH THE ARPT WHO TEND TO FLY BY THE BOOK OWING TO LESS FAMILIARITY WITH THE TERRAIN.
