Cause areas

  • Pilot in command › Flight into adverse weather, attempted
  • Pilot in command › Lack of total experience in type operation
  • Pilot in command › Weather evaluation, misjudged

NTSB narrative

DURING THE PILOT'S PREFLIGHT WEATHER BRIEFING HE WAS TOLD THAT ICING CONDITIONS WERE FORECAST NEAR HIS ROUTE OF FLIGHT BELOW 16,000 FT, AND HIS ROUTE MAY INVOLVE FLYING BETWEEN TWO FRONTS. THE PILOT FILED FOR AND RECEIVED AN INSTRUMENT CLEARANCE TO FLY AT THE MEA OF 11,000 FT. THE PILOT WAS TOLD THAT SEVERAL INBOUND AIRCRAFT ENCOUNTERED ICING CONDITIONS AT 9,000 FT. THE PILOT TOOK OFF AND, 34 MINUTES LATER, REPORTED HE WAS PICKING UP ICE AND HIS PITOT/STATIC SYSTEM WAS ICED OVER. UNABLE TO CLIMB TO THE MEA, THE PILOT RECEIVED AN APPROACH CLEARANCE FOR A NEARBY AIRPORT. WHILE CRUISING BETWEEN 9,200 & 9,700 FT IN AN AREA WHERE THE MEA WAS 11,000 FT, THE PILOT SAID HE WAS STILL TRYING TO CLIMB AND WAS PICKING UP QUITE A LITTLE BIT OF ICING AND GOT AN OPAQUE WINDSHIELD. THE PILOT REPORTED THAT HE WAS 17.9 MILES OUT FROM THE AIRPORT. IN JULY 1995, THE ACFT WAS LOCATED 14.5 MILES AND 353 DEG FROM THE ARPT. THE LOCATION WAS NOT ON ANY FEDERAL AIRWAY OR ROUTE STRUCTURE ASSOCIATED WITH THE INSTRUMENT APPROACH PROCEDURE. THE PILOT WAS ISSUED AN INSTRUMENT RATING 3 WEEKS PRIOR TO THE ACCIDENT FLIGHT.

Probable cause

the pilot's intentional flight into known adverse weather conditions, his misjudged evaluation of the weather, and his inexperience in actual instrument flying.

  • 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.
