NTSB narrative

DURING LANDING ROLLOUT IN VFR CONDITIONS, A DC-3C, OPERATED BY A 14 CFR PART 135 OPERATOR, ON A 14 CFR PART 91 POSITIONING FLIGHT, NOSED DOWN ON THE RUNWAY SUBSTAINING MINOR DAMAGE. THE PIC, SIC, UNAUTHORIZED JUMPSEAT RIDER, AND TWO CARGO LOADERS LOCATED IN THE COCKPIT/FORWARD COMPARTMENT WERE NOT INJURED. NO CARGO, BALLAST, OR PASSENGER SEATS FOR THE CARGO LOADERS WERE LOCATED IN THE REAR OF THE AIRPLANE AT THE TIME OF THE INCIDENT.

Probable cause

THE PILOT-IN-COMMAND'S IMPROPER LOADING OF PERSONNEL, AND IMPROPER SUPERVISION OF THE FIRST OFFICER/CO-PILOT WHILE CALCULATING THE CENTER OF GRAVITY LIMITS FOR THE FLIGHT. THIS RESULTED IN THE FORWARD CENTER OF GRAVITY LIMIT BEING EXCEEDED AND SUBSEQUENT NOSE DOWN OF THE AIRPLANE ON THE RUNWAY DURING THE LANDING ROLL. CONTRIBUTING TO THE ACCIDENT WAS THE ABSENCE OF PASSENGER SEATS FOR THE CARGO LOADERS OR BALLAST IN THE REAR OF THE AIRPLANE AT THE TIME OF THE INCIDENT.

  • 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.
