Narrative:

Aircraft #1 (small aircraft 1) contained 2 pilots, pilot #1 under the hood flying ILS approach to runway 23 at frederick, md (fdk) with pilot #2 in right seat acting as safety. Pilot #1 broke off instrument approach to runway 23. At approximately 1.5 mi from departure end of runway 30, pilot #2 executed a left hand turn (crosswind of runway 30) to proceed on swesterly heading to leesburg (jyo). Scan of area revealed no aircraft in flight off of runway 30, one aircraft on roll and no airborne traffic in immediate vicinity. At approximately 2 mi past runway 30, pilot #1 (aircraft 1) observed small aircraft 2 to the right and behind aircraft #1 at a slightly higher altitude (approximately 1550 ft) and 200 yards behind. No evasive maneuver required by aircraft #1 at this time. No evasive maneuver by the small aircraft 2 was observed. Prior to incident, scan by pilot #2 in aircraft #1 did not detect a possible conflict or the presence of the small aircraft 2. Flight path of small aircraft 2 prior to observation unknown but it is suspected that small aircraft 2 may have just completed a left turn to downwind for landing on runway 30 at fdk. Also, prior to observation of small aircraft 2 both pilots in aircraft #1 were observing the flight of a large bird in close proximity to the aircraft and on possible collision course. (Bird at 11 O'clock position and closing on aircraft.) further, I (pilot #2, aircraft #1) should have climbed to 500 ft above pattern altitude prior to attempting to cross the flight path off of runway 30. Both pilots in aircraft #1 believed pattern altitude at fsk to be 1100 ft actual planned altitude = 1305 ft. Altitude with aircraft margin for safety in the fdk traffic environment.

Title: SMA PRACTICING INST WORK WITH 2 PLTS ABOARD HAS NMAC IN TFC PATTERN. UNCTLED FIELD.

Narrative: ACFT #1 (SMA 1) CONTAINED 2 PLTS, PLT #1 UNDER THE HOOD FLYING ILS APCH TO RWY 23 AT FREDERICK, MD (FDK) WITH PLT #2 IN R SEAT ACTING AS SAFETY. PLT #1 BROKE OFF INST APCH TO RWY 23. AT APPROX 1.5 MI FROM DEP END OF RWY 30, PLT #2 EXECUTED A L HAND TURN (XWIND OF RWY 30) TO PROCEED ON SWESTERLY HDG TO LEESBURG (JYO). SCAN OF AREA REVEALED NO ACFT IN FLT OFF OF RWY 30, ONE ACFT ON ROLL AND NO AIRBORNE TFC IN IMMEDIATE VICINITY. AT APPROX 2 MI PAST RWY 30, PLT #1 (ACFT 1) OBSERVED SMA 2 TO THE R AND BEHIND ACFT #1 AT A SLIGHTLY HIGHER ALT (APPROX 1550 FT) AND 200 YARDS BEHIND. NO EVASIVE MANEUVER REQUIRED BY ACFT #1 AT THIS TIME. NO EVASIVE MANEUVER BY THE SMA 2 WAS OBSERVED. PRIOR TO INCIDENT, SCAN BY PLT #2 IN ACFT #1 DID NOT DETECT A POSSIBLE CONFLICT OR THE PRESENCE OF THE SMA 2. FLT PATH OF SMA 2 PRIOR TO OBSERVATION UNKNOWN BUT IT IS SUSPECTED THAT SMA 2 MAY HAVE JUST COMPLETED A L TURN TO DOWNWIND FOR LNDG ON RWY 30 AT FDK. ALSO, PRIOR TO OBSERVATION OF SMA 2 BOTH PLTS IN ACFT #1 WERE OBSERVING THE FLT OF A LARGE BIRD IN CLOSE PROX TO THE ACFT AND ON POSSIBLE COLLISION COURSE. (BIRD AT 11 O'CLOCK POS AND CLOSING ON ACFT.) FURTHER, I (PLT #2, ACFT #1) SHOULD HAVE CLBED TO 500 FT ABOVE PATTERN ALT PRIOR TO ATTEMPTING TO CROSS THE FLT PATH OFF OF RWY 30. BOTH PLTS IN ACFT #1 BELIEVED PATTERN ALT AT FSK TO BE 1100 FT ACTUAL PLANNED ALT = 1305 FT. ALT WITH ACFT MARGIN FOR SAFETY IN THE FDK TFC ENVIRONMENT.
