Beech 58 Accident on Gravel Road in Limpopo (ZS-MBT)

Accident Overview and Aircraft Details On 18 June 2005, a Beech 58 with registration ZS-MBT was involved in an accident while operating as a private flight. The aircraft departed Wonderboom Aerodrome in Gauteng at approximately 0620Z, carrying the pilot and three passengers, all of whom were children. The intended destination was a private aerodrome located on a farm approximately 20 nautical miles from Vivo in the Limpopo Province. The pilot held a valid private licence and had 111.5 hours of flying experience on the type. ## Sequence of Events The pilot had previously visited the farm on 11 June 2005 and inspected a gravel runway with floodlights, confirming it was suitable for landing. On the day of the accident, the flight proceeded without incident for approximately 55 minutes. Upon arrival, the pilot flew over the hangar and runway, then turned the aircraft around for landing. He selected 25 degrees of flaps at an indicated airspeed of approximately 65 mph and broadcast his intentions on 124.8 MHz. The initial landing was smooth, but as the ground roll speed decreased to about 40 mph, the aircraft ran over a hump across the surface, which caused it to be catapulted back into the air. ## Impact and Damage When the aircraft came down, the pilot lost directional control. The nose wheel impacted the ground first, followed by the left-hand wing. The aircraft subsequently ground looped and collided with a boundary steel pole of an electrified wire fence. The pilot realized after the accident that he had unintentionally landed on a gravel road rather than the private runway he had inspected days earlier. All occupants escaped unharmed. The aircraft sustained damage to the left and right wings, fuselage, tail plane, and propeller blades. ## Maintenance and Weather The last mandatory periodic inspection was certified on 9 June 2005 at 4,378.0 airframe hours. At the time of the accident, the aircraft had 4,387.7 total airframe hours, meaning it had flown 9.7 hours since the last inspection. Weather conditions at the time were fine, with calm surface winds and a temperature of 18°C.
