Narrative:
On may/sat/92, I departed runway 31 at the north bend airport at approximately HH20. As I became airborne, I noticed an unrpted ultralight type aircraft making a fly-by over the airport at my 1 O'clock position. Performing evasive action, I then made a non-standard turn off of runway 31 at midfield. It was unknown to myself that I had flown over a helicopter that had just started its engine. The helicopter had just begun ignition as I passed over him at an altitude of at least 250 ft. After passing over the helicopter, I flew over the FBO at an altitude of 350-400 ft continuing my climb out in an attempt not to get any closer to the ultralight aircraft. My closeness to the helicopter and the buildings were inadvertent, and I felt that the evasive action was necessary in order to avoid a possible collision with the ultralight vehicle.

Title: AN SMA PLT TOOK EVASIVE ACTION RIGHT AFTER TKOF AND OVERFLEW A HELI ON THE GND. THE RPTR SAYS THAT THERE WAS AN ULTRALIGHT ACFT OVER THE ARPT.
Narrative: ON MAY/SAT/92, I DEPARTED RWY 31 AT THE N BEND ARPT AT APPROX HH20. AS I BECAME AIRBORNE, I NOTICED AN UNRPTED ULTRALIGHT TYPE ACFT MAKING A FLY-BY OVER THE ARPT AT MY 1 O'CLOCK POS. PERFORMING EVASIVE ACTION, I THEN MADE A NON-STANDARD TURN OFF OF RWY 31 AT MIDFIELD. IT WAS UNKNOWN TO MYSELF THAT I HAD FLOWN OVER A HELI THAT HAD JUST STARTED ITS ENG. THE HELI HAD JUST BEGUN IGNITION AS I PASSED OVER HIM AT AN ALT OF AT LEAST 250 FT. AFTER PASSING OVER THE HELI, I FLEW OVER THE FBO AT AN ALT OF 350-400 FT CONTINUING MY CLBOUT IN AN ATTEMPT NOT TO GET ANY CLOSER TO THE ULTRALIGHT ACFT. MY CLOSENESS TO THE HELI AND THE BUILDINGS WERE INADVERTENT, AND I FELT THAT THE EVASIVE ACTION WAS NECESSARY IN ORDER TO AVOID A POSSIBLE COLLISION WITH THE ULTRALIGHT VEHICLE.
