Narrative:
While approaching ewb, I passed an airplane which could not be seen until very close. The reason for this was that the other airplane's position lights were not visible nor did it have a red rotating beacon or strobe light. After we landed at ewb and the other aircraft did also, it was obvious that the position lights were very dim and it had no beacon/strobe system. The other aircraft was an small aircraft, an airplane which has no real electrical system. Airplane was modified for position lights pwred by a separate battery. Evasive action was steep turn to the left with a climb.
Original NASA ASRS Text
Title: SMT HAS AN NMAC WITH AN SMA WHOSE NAV LIGHTS WERE VERY DIM.
Narrative: WHILE APCHING EWB, I PASSED AN AIRPLANE WHICH COULD NOT BE SEEN UNTIL VERY CLOSE. THE REASON FOR THIS WAS THAT THE OTHER AIRPLANE'S POS LIGHTS WERE NOT VISIBLE NOR DID IT HAVE A RED ROTATING BEACON OR STROBE LIGHT. AFTER WE LANDED AT EWB AND THE OTHER ACFT DID ALSO, IT WAS OBVIOUS THAT THE POS LIGHTS WERE VERY DIM AND IT HAD NO BEACON/STROBE SYS. THE OTHER ACFT WAS AN SMA, AN AIRPLANE WHICH HAS NO REAL ELECTRICAL SYS. AIRPLANE WAS MODIFIED FOR POS LIGHTS PWRED BY A SEPARATE BATTERY. EVASIVE ACTION WAS STEEP TURN TO THE L WITH A CLB.
