NTSB narrative

THE NON-INSTRUMENT RATED PLT & 3 PAX PLANNED A PLEASURE FLT TO MX. THE WEATHER WAS BELOW VFR MINIMUMS HOWEVER THE PLT ELECTED TO ATTEMPT THE FLT. SEVERAL MINUTES AFTER DEPARTURE THE ACFT WAS OBSERVED TO ENTER AN AREA WHERE IT WAS SNOWING, THE CLOUD BASE WAS ESTIMATED AT 200 FEET AGL, & THE VISIBILITY VARIED FROM 50 FT TO 1 MILE. A WITNESS OBSERVED AN ACFT FLYING BELOW THE CLOUDS IN A STEEP LEFT BANK. THE ACFT SUDDENLY ROLLED RIGHT, PITCHED UPWARDS (ABT 30 DEGREES) AND FLEW INTO THE CLOUDS. ANOTHER WITNESS, LOCATED IN HIS HOUSE ABT 150 FT SOUTH OF THE ACC SITE, HEARD A SOUND LIKE AN ACFT ENG IN A POWER DIVE. HE THEN HEARD A LOUD DULL THUD AND LOOKED OUTSIDE AND SAW THE ACFT IN HIS APPLE ORCHARD. EXAM OF THE ACFT & ENG DID NOT REVEAL ANY PREIMPACT FAILURES OR MALFUNCTIONS.

  • 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.
