NTSB narrative
THIS CESSNA/ROBERTSON 337 WAS DEPARTING FROM A 1600 FOOT GRASS STRIP IN VFR CONDITIONS. THERE WERE GUSTING HEAD WINDS ESTIMATED AT 15 KNOTS. AT THE MIDPOINT OF THE RUNWAY THE AIRCRAFT MADE A STEEP CLIMBING LEFT TURN, STALLING AFTER ABOUT 180 DEGREES OF TURN. THE ACFT NOSE DROPPED AND THE ACFT DESCENDED VERTICALLY TO THE GROUND. WITNESSES ESTIMATED THE MAX HEIGHT GAINED WAS FROM 100-250 FT AGL. THEY DESCRIBED THE ENG NOISE AS LOUD AND CONSTANT FROM TAKEOFF UNTIL THE CRASH. THE ACFT CAME TO REST ABOUT 400 FT WEST OF THE RWY MIDPOINT IN LEVEL TERRAIN.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1988-10-02.
