The flight was categorized as cargo and the reported phase was takeoff (climb) at a airport (less than 10 km from airport) crash site.

The listed crash cause is human factor. Final power assurance checks were carried out on the aircraft’s engines on the morning of the accident. The AME (Aircraft Maintenance Engineer) trimmed the elevator-trim tab to the Full Nose UP position in order to reduce the stick forces required to hold the tail down during the engine power checks, but he did not set the elevator trim back to the neutral position on completion of the checks. The AME was requested by the pilot(s) to remove the aileron and elevator external gust locks and the landing gear down lock pins. He left the rudder lock in place, which was later removed by one of the pilots. The pilot(s) did not carry out a pre-flight inspection. At approximately 1646 on 24 August 1998 the DC3TP, registration number ZS-NKK, crashed during take-off from runway 11 at Wonderboom Airport. The PIC (Pilot-in-Command), who did not wear a shoulder harness, sustained fatal injuries and the co-pilot, who did wear a shoulder harness, serious injures. The accident occurred on the first flight after the aircraft had undergone a maintenance inspection, which included power assurance checks of the engines. The co-pilot sat in the left-hand seat and while he started the engines, the PIC attended to the cockpit checklist.
Aircraft reference details include registration ZS-NKK, MSN 13143, year of manufacture 1944.
