Narrative:
My aircraft was on a left downwind approach for landing when an experimental aircraft flew directly in front and slightly above me without announcing intentions, even though he did have a radio, on which he eventually acknowledged he would slow to follow my approach. The problem was caused by nonstandard operating procedures on the other pilot's part, and could perhaps be rectified by requiring communications procedures at uncontrolled airports.
Original NASA ASRS Text
Title: A CESSNA 172 PLT RPTS AN NMAC WITH AN EXPERIMENTAL ACFT IN THE 2V2 TFC PATTERN. NON TWR ARPT CTAF. EVASIVE ACTION UNSPECIFIED.
Narrative: MY ACFT WAS ON A L DOWNWIND APCH FOR LNDG WHEN AN EXPERIMENTAL ACFT FLEW DIRECTLY IN FRONT AND SLIGHTLY ABOVE ME WITHOUT ANNOUNCING INTENTIONS, EVEN THOUGH HE DID HAVE A RADIO, ON WHICH HE EVENTUALLY ACKNOWLEDGED HE WOULD SLOW TO FOLLOW MY APCH. THE PROB WAS CAUSED BY NONSTANDARD OPERATING PROCS ON THE OTHER PLT'S PART, AND COULD PERHAPS BE RECTIFIED BY REQUIRING COMS PROCS AT UNCTLED ARPTS.
