THE AIRCREW TOOK OFF ON AN IFR FLT FROM DAYTON TO PIQUA & SIDNEY, OH TO PRACTICE APCH'S, THEN THEY INTENDED TO RETURN TO DAYTON. THE COPILOT STATED THAT THEY ENTERED THE CLOUDS AT 700 TO 800 FT AGL & HE DID NOT SEE THE GROUND AGAIN ON THIS FLT. HE REPORTED THAT ICE BEGAN BUILDING ON THE ACFT UNTIL ON A DESCENT TOWARD PIQUA, WHEN REPORTEDLY, IT BEGAN DISSIPATING. A MISSED APCH WAS MADE AT PIQUA WITHOUT SEEING THE ARPT. THE COPILOT STATED THAT THEY WERE UNABLE TO GET A GOOD RATE OF CLIMB. AT 1258 EST, THE AIRCREW REQUESTED VECTORS BACK TO DAYTON (RATHER THAN TO CONTINUE TO SIDNEY) & ADVISED THAT THEY WERE ENCOUNTERING ICE & TURBULENCE. THEY WERE ISSUED A VECTOR, BUT APRX 30 SEC LATER, THEY ADVISED THAT THEY COULD NOT MAINTAIN THEIR ASSIGNED ALT OF 3000 FT.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
  • API snapshot SHA-256: d9ccdf2ea8231026df7246c497fa33dd6f7d1dfaef389a7d0c347714a69455dc; retrieved 2026-09-21T05:46:17.800Z.
