Narrative:

During climb after the initial takeoff during a commercial pilot's biennial flight review, a turn from 250 degrees to 180 degrees was commenced at about 800-900 ft. The destination airport was edenton (ede), nc. While on a 45 degree departure/climb from runway heading, a tan/brown small aircraft Y passed directly overhead about 100 ft, coming from behind my right wing. She was entering left downwind from a wnw direction, vice the standard 45 degree entry outlined in the aim. A full call sign/north-number was never heard. This incident was witnessed by a sky diving club pilot taking off about 45 seconds behind me. He made a broadcast over CTAF at the instant the small aircraft Y was passing overhead. The witness later told me that the small aircraft was descending and turning, thus passing through the crosswind leg to enter downwind for sfq runway 25. Note: about 6 months ago a midair collision did occur at the exact place, 2 small aircraft's both with CFI's aboard! No one died, but the cause was the same -- nonstandard traffic pattern entry.

Title: NMAC BTWN 2 SMA'S AT A NON TWR ARPT. DEP ARR TFC.

Narrative: DURING CLB AFTER THE INITIAL TKOF DURING A COMMERCIAL PLT'S BIENNIAL FLT REVIEW, A TURN FROM 250 DEGS TO 180 DEGS WAS COMMENCED AT ABOUT 800-900 FT. THE DEST ARPT WAS EDENTON (EDE), NC. WHILE ON A 45 DEG DEP/CLB FROM RWY HDG, A TAN/BROWN SMA Y PASSED DIRECTLY OVERHEAD ABOUT 100 FT, COMING FROM BEHIND MY R WING. SHE WAS ENTERING L DOWNWIND FROM A WNW DIRECTION, VICE THE STANDARD 45 DEG ENTRY OUTLINED IN THE AIM. A FULL CALL SIGN/N-NUMBER WAS NEVER HEARD. THIS INCIDENT WAS WITNESSED BY A SKY DIVING CLUB PLT TAKING OFF ABOUT 45 SECONDS BEHIND ME. HE MADE A BROADCAST OVER CTAF AT THE INSTANT THE SMA Y WAS PASSING OVERHEAD. THE WITNESS LATER TOLD ME THAT THE SMA WAS DSNDING AND TURNING, THUS PASSING THROUGH THE XWIND LEG TO ENTER DOWNWIND FOR SFQ RWY 25. NOTE: ABOUT 6 MONTHS AGO A MIDAIR COLLISION DID OCCUR AT THE EXACT PLACE, 2 SMA'S BOTH WITH CFI'S ABOARD! NO ONE DIED, BUT THE CAUSE WAS THE SAME -- NONSTANDARD TFC PATTERN ENTRY.
