## Analysis

THE HANSA JET HFB-320 ACFT CRASHED ON TAKEOFF FROM THE ABERDEEN AIRPORT AFTER THE FLT CREW SELECTED THE INCORRECT RWY FOR TAKEOFF. THE ACFT WAS OBSERVED RUNNING OFF THE END OF RWY 17, WHICH IS 3860 FT LONG, WHERE IT STRUCK A FENCE, DITCH, ROAD & ANOTHER DITCH THEN BECAME AIRBORNE, THE LANDING GEAR SEPARATED DURING THE ABOVE SEQUENCE. THE ACFT WAS THAN OBSERVED TO LEVEL OFF MOMENTARILY, THEN DESCEND IN A RT TURN UNTIL IMPACT. INVESTIGATION REVEALED THE CREW HAD BEEN FLYING 12 HRS EXCEPT FOR REFUELING STOPS & CARGO LOADING. IN ADDITION, CALCULATIONS REVEALED THE ACFT WAS OVER GROSS WT BY APPROX 1 TON. THE PROPER RWY FOR TAKEOFF WAS 13 (40 DEGREE CHANCE) AND 6900 FT LONG. RWY USED WAS RESTRICTED TO ACFT LES THAN 12,500 GTO WT. N127MW WEIGHED OVER 20,000 LBS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19841004076339A](https://openairdocs.org/incident/19841004076339A), Oct 4, 1984: Hamflu HFB320, Aberdeen, SD, Destroyed, 1 fatal. Pilots turned onto wrong runway at night. Overgross not certificated cargo flight did not have sufficient runway.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
