Narrative:
I requested a SVFR clearance into the bet control zone at night. I am current as an INS rated pilot; however, the aircraft, though IFR equipped, was not current at the time. I was using for navigation an ADF for primary navigation, backed up by a LORAN, then the VOR. The VOR is also an ILS instrument. Due to fast deteriorating WX with icing conditions, I elected in the interest of safety not to fly to an alternate airport. Bet has the most navaids and the best lighting system in the area, and was a key factor in my decision to request an SVFR. The WX on departure from bet was currently VFR and did not start to deteriorate until I neared the end of my trip. The WX was reported to be sky partially obscured, 300 overcast, visibility 5 mi in light snow and fog, VFR flight not recommended. The WX in the area was also worsening and icing conditions were present. I elected not to fly to an alternate airport in these conditions, even though I had enough fuel. The VOR had not had an a current accuracy check, but I was using the ADF for primary navigation. The aircraft had not had a current pitot-static check for IFR flight--the aircraft was not intended for IFR flight. With only those 2 systems not current, the aircraft was equipped for IFR flight.
Original NASA ASRS Text
Title: ATX WAS OPERATED SVFR WHEN ACFT INSTRUMENTATION WAS NOT CURRENT.
Narrative: I REQUESTED A SVFR CLRNC INTO THE BET CTL ZONE AT NIGHT. I AM CURRENT AS AN INS RATED PLT; HOWEVER, THE ACFT, THOUGH IFR EQUIPPED, WAS NOT CURRENT AT THE TIME. I WAS USING FOR NAV AN ADF FOR PRIMARY NAV, BACKED UP BY A LORAN, THEN THE VOR. THE VOR IS ALSO AN ILS INSTRUMENT. DUE TO FAST DETERIORATING WX WITH ICING CONDITIONS, I ELECTED IN THE INTEREST OF SAFETY NOT TO FLY TO AN ALTERNATE ARPT. BET HAS THE MOST NAVAIDS AND THE BEST LIGHTING SYS IN THE AREA, AND WAS A KEY FACTOR IN MY DECISION TO REQUEST AN SVFR. THE WX ON DEP FROM BET WAS CURRENTLY VFR AND DID NOT START TO DETERIORATE UNTIL I NEARED THE END OF MY TRIP. THE WX WAS RPTED TO BE SKY PARTIALLY OBSCURED, 300 OVCST, VISIBILITY 5 MI IN LIGHT SNOW AND FOG, VFR FLT NOT RECOMMENDED. THE WX IN THE AREA WAS ALSO WORSENING AND ICING CONDITIONS WERE PRESENT. I ELECTED NOT TO FLY TO AN ALTERNATE ARPT IN THESE CONDITIONS, EVEN THOUGH I HAD ENOUGH FUEL. THE VOR HAD NOT HAD AN A CURRENT ACCURACY CHK, BUT I WAS USING THE ADF FOR PRIMARY NAV. THE ACFT HAD NOT HAD A CURRENT PITOT-STATIC CHK FOR IFR FLT--THE ACFT WAS NOT INTENDED FOR IFR FLT. WITH ONLY THOSE 2 SYSTEMS NOT CURRENT, THE ACFT WAS EQUIPPED FOR IFR FLT.
