NTSB narrative
The pilot stated that after four parachutists had boarded the airplane, he began to taxi away from the gate. The pilot stated that the airplane traveled about 25 yards on the upward sloping grass terrain when the right main landing gear collapsed. Examination of the landing gear revealed a break approximately 10 inches from the inboard end of the landing gear leg at a point where it is clamped to the fuselage structure. Further examination of the airplane revealed no other anomalies. Examination of the landing gear by the Materials Laboratory Division of the National Transportation Safety Board indicated that the break stemmed from preexisting fatigue regions located on the lower forward surface of the landing gear leg. This area of the gear also contained evidence of fretting damage in areas where there had been a loss of paint.
Probable cause
the collapse of the right main landing gear from a preexisting fatigue crack.

- 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.
