Narrative:

1) aircraft B in area going opposite direction of left downwind traffic to runway 14. 2) B did not use his radio to give his position. Also, the light rain on our windshield did not help (need windshield wipers). 3) both pilots in aircraft a are CFI and we know it takes a lot of looking to see other traffic and that was what we were doing. 4) nose dive trying to avoid B. 5) I think the B pilot used poor judgement flying into a traffic pattern wrong way and not using radio that he did have aboard. I think the good judgement and fast decision and action taken by my copilot saved 9 people's lives and one dog. 6) actions: more training about what goes on around airports. 7) I think the B pilot was just trying to get home in bad WX. Note: would be nice if all planes had LORAN, so pilots would know their position. We were on IFR flight plan from ast, nc to sby, md. Patuxent approach control on 127.95 had cleared us for a visual approach to runway 14, transponder set XXXX on mode C. We were told to contact sby radio on 123.6. After contact with sby radio, we were advised of traffic, an small aircraft C was taking off on runway 14 (the C was doing touch and goes). Also, another small aircraft B was 5 mi south of sby VOR. No other reported traffic. I saw the C taking off on runway 14. We crossed airport and turned to enter left downwind to runway 14 and had let down to 1200'. At the numbers on left downwind to runway 14, we had 15 degree flaps and gear down and speed about 130/140 KTS. Just before turning to base leg for runway 14, my copilot saw an small aircraft B at our altitude going the opposite direction (maybe 14 degree to 160 degree heading). We were on a 320 degree heading at this time. At this time my copilot took the controls and by evasive action went into a nose dive trying to miss B. The B right wing tip hit our aircraft on the right side of the vertical stabilizer and rudder. (Vertical stabilizer was hit about 1' forward of the rudder and down to about 3' below top of rudder.) after the midair collision the B made his 1ST radio contact with sby radio. We advised sby radio we were still flying and that we thought the B might have hit us with his landing gear. We went on to land on runway 14 and the B landed on runway 32 from a right downwind. Mr X was on duty at sby FSS at the time, and he saw the position of both planes right after the midair collision. WX at sby from my position was, clouds 2000' broken and about 4 mi visibility. There were some scud north of the airport at about 1800' and some light rain in the area. FAA and NTSB said I did not need to fill out any accident report form. They classified this midair as an incident. (I did fill out a form fs 8020-50 at sby FSS on day of midair.) I also talked to AOPA and was told I should send a report of this to NASA.

Title: SMT ACFT AND SMA HAD MIDAIR COLLISION. BOTH ACFT LANDED. SMT HAD MINOR TO SEVERE DAMAGE.

Narrative: 1) ACFT B IN AREA GOING OPPOSITE DIRECTION OF LEFT DOWNWIND TFC TO RWY 14. 2) B DID NOT USE HIS RADIO TO GIVE HIS POSITION. ALSO, THE LIGHT RAIN ON OUR WINDSHIELD DID NOT HELP (NEED WINDSHIELD WIPERS). 3) BOTH PLTS IN ACFT A ARE CFI AND WE KNOW IT TAKES A LOT OF LOOKING TO SEE OTHER TFC AND THAT WAS WHAT WE WERE DOING. 4) NOSE DIVE TRYING TO AVOID B. 5) I THINK THE B PLT USED POOR JUDGEMENT FLYING INTO A TFC PATTERN WRONG WAY AND NOT USING RADIO THAT HE DID HAVE ABOARD. I THINK THE GOOD JUDGEMENT AND FAST DECISION AND ACTION TAKEN BY MY COPLT SAVED 9 PEOPLE'S LIVES AND ONE DOG. 6) ACTIONS: MORE TRAINING ABOUT WHAT GOES ON AROUND ARPTS. 7) I THINK THE B PLT WAS JUST TRYING TO GET HOME IN BAD WX. NOTE: WOULD BE NICE IF ALL PLANES HAD LORAN, SO PLTS WOULD KNOW THEIR POSITION. WE WERE ON IFR FLT PLAN FROM AST, NC TO SBY, MD. PATUXENT APCH CTL ON 127.95 HAD CLRED US FOR A VISUAL APCH TO RWY 14, XPONDER SET XXXX ON MODE C. WE WERE TOLD TO CONTACT SBY RADIO ON 123.6. AFTER CONTACT WITH SBY RADIO, WE WERE ADVISED OF TFC, AN SMA C WAS TAKING OFF ON RWY 14 (THE C WAS DOING TOUCH AND GOES). ALSO, ANOTHER SMA B WAS 5 MI S OF SBY VOR. NO OTHER REPORTED TFC. I SAW THE C TAKING OFF ON RWY 14. WE CROSSED ARPT AND TURNED TO ENTER LEFT DOWNWIND TO RWY 14 AND HAD LET DOWN TO 1200'. AT THE NUMBERS ON LEFT DOWNWIND TO RWY 14, WE HAD 15 DEG FLAPS AND GEAR DOWN AND SPEED ABOUT 130/140 KTS. JUST BEFORE TURNING TO BASE LEG FOR RWY 14, MY COPLT SAW AN SMA B AT OUR ALT GOING THE OPPOSITE DIRECTION (MAYBE 14 DEG TO 160 DEG HDG). WE WERE ON A 320 DEG HDG AT THIS TIME. AT THIS TIME MY COPLT TOOK THE CONTROLS AND BY EVASIVE ACTION WENT INTO A NOSE DIVE TRYING TO MISS B. THE B RIGHT WING TIP HIT OUR ACFT ON THE RIGHT SIDE OF THE VERTICAL STABILIZER AND RUDDER. (VERTICAL STABILIZER WAS HIT ABOUT 1' FORWARD OF THE RUDDER AND DOWN TO ABOUT 3' BELOW TOP OF RUDDER.) AFTER THE MIDAIR COLLISION THE B MADE HIS 1ST RADIO CONTACT WITH SBY RADIO. WE ADVISED SBY RADIO WE WERE STILL FLYING AND THAT WE THOUGHT THE B MIGHT HAVE HIT US WITH HIS LNDG GEAR. WE WENT ON TO LAND ON RWY 14 AND THE B LANDED ON RWY 32 FROM A RIGHT DOWNWIND. MR X WAS ON DUTY AT SBY FSS AT THE TIME, AND HE SAW THE POSITION OF BOTH PLANES RIGHT AFTER THE MIDAIR COLLISION. WX AT SBY FROM MY POSITION WAS, CLOUDS 2000' BROKEN AND ABOUT 4 MI VISIBILITY. THERE WERE SOME SCUD N OF THE ARPT AT ABOUT 1800' AND SOME LIGHT RAIN IN THE AREA. FAA AND NTSB SAID I DID NOT NEED TO FILL OUT ANY ACCIDENT REPORT FORM. THEY CLASSIFIED THIS MIDAIR AS AN INCIDENT. (I DID FILL OUT A FORM FS 8020-50 AT SBY FSS ON DAY OF MIDAIR.) I ALSO TALKED TO AOPA AND WAS TOLD I SHOULD SEND A REPORT OF THIS TO NASA.
