Night Flight Accident Involving a Navion at Springbok (ZS-TOM)

Accident Overview and Aircraft Details On 28 March 2001, a Navion aircraft with registration ZS-TOM was involved in a fatal accident near Springbok Aerodrome. The flight was a private operation from Springbok Aerodrome to Springs Aerodrome. The pilot-in-command held a valid licence and had a total flying experience of 1,286 hours and 35 minutes, including 430 hours and 10 minutes on the aircraft type. ## Accident Sequence and Location The aircraft took off early in the morning under typical night conditions, with the eastern sky just beginning to lighten. After take-off, the aircraft entered a tight left-hand turn and struck a mountain. The initial impact involved the right-hand wing, after which the aircraft rolled over and impacted the top surface of the mountain in an inverted attitude. The accident site was located approximately 1 nautical mile north-east (215°) of Springbok Aerodrome, at coordinates S29° 40.366' E017° 56.587'. ## Casualties and Aircraft Condition The pilot was fatally injured during the impact. No other persons were on board, and no injuries were reported. An examination of the aircraft revealed no defects with the aircraft or its systems. ## Probable Cause The investigation determined that the pilot suffered from spatial disorientation during take-off in night/very early morning light conditions, resulting in a loss of control of the aircraft. Although the pilot was night-rated, he had not flown in night conditions in the preceding 23 months.
