Narrative:

Making approach to uncontrolled field. Call in to multicom at 1500 ft, 1200 ft crossing mid-field, 800 ft on downwind for runway 8 for 'touch and goes.' 3 tour helicopters are parked on the grass beside the ramp. The approach end of field is obscured by bushes and trees. As I flared for landing (over the numbers) a helicopter came out from the grass over the runway into (or slightly above) my path, turned 180 degrees immediately back off the runway to avoid me and then departed. I continued on without landing to keep flying speed in anticipation of blast of wind from his rotor blades, and I reentered the pattern and made a normal full stop landing. Contributing factors: I failed to announce base and final turns which may have stopped him from lifting off, bushes obscure the approach end of runway 8 from the helicopter landing area, helicopters use that area as a loading and unloading area for tour passenger -- commercial operation, and helicopters use some different frequencys in that area and aircraft #2 might not have been monitoring 122.9 multicom (although one of the pilots acknowledged my approach and said he'd be looking out for me).

Title: C150 MAKING TOUCH AND GO LNDGS HAS NMAC WITH TOUR HELI.

Narrative: MAKING APCH TO UNCTLED FIELD. CALL IN TO MULTICOM AT 1500 FT, 1200 FT XING MID-FIELD, 800 FT ON DOWNWIND FOR RWY 8 FOR 'TOUCH AND GOES.' 3 TOUR HELIS ARE PARKED ON THE GRASS BESIDE THE RAMP. THE APCH END OF FIELD IS OBSCURED BY BUSHES AND TREES. AS I FLARED FOR LNDG (OVER THE NUMBERS) A HELI CAME OUT FROM THE GRASS OVER THE RWY INTO (OR SLIGHTLY ABOVE) MY PATH, TURNED 180 DEGS IMMEDIATELY BACK OFF THE RWY TO AVOID ME AND THEN DEPARTED. I CONTINUED ON WITHOUT LNDG TO KEEP FLYING SPD IN ANTICIPATION OF BLAST OF WIND FROM HIS ROTOR BLADES, AND I REENTERED THE PATTERN AND MADE A NORMAL FULL STOP LNDG. CONTRIBUTING FACTORS: I FAILED TO ANNOUNCE BASE AND FINAL TURNS WHICH MAY HAVE STOPPED HIM FROM LIFTING OFF, BUSHES OBSCURE THE APCH END OF RWY 8 FROM THE HELI LNDG AREA, HELIS USE THAT AREA AS A LOADING AND UNLOADING AREA FOR TOUR PAX -- COMMERCIAL OP, AND HELIS USE SOME DIFFERENT FREQS IN THAT AREA AND ACFT #2 MIGHT NOT HAVE BEEN MONITORING 122.9 MULTICOM (ALTHOUGH ONE OF THE PLTS ACKNOWLEDGED MY APCH AND SAID HE'D BE LOOKING OUT FOR ME).
