Factual narrative
THE PLT MADE AN APCH OVER TALL TREES TO LAND ON A 2050 FT STRIP. THE ACFT TOUCHED DOWN ON WET TURF WITH ABOUT 500 FT OF RWY REMAINING. THE PLT WAS UNABLE TO STOP THE ACFT ON THE REMAINING RWY. SUBSEQUENTLY, IT CONTD OFF THE DEPARTURE END & WENT INTO A LARGE DITCH. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
