What happened
On 25 February 2007, a Cessna C177RG, registration ZS-NNR, was performing circuit and landing patterns at Stellenbosch Aerodrome in the Western Cape. During the landing phase of the operation, the pilot experienced a loss of directional control. The aircraft veered off the runway and entered a nearby ditch. The impact caused the nose landing gear to collapse and resulted in the propeller striking the ground. Despite the impact, there were no injuries to the pilot or the passenger on board.
The investigation
The investigation was conducted via postal inquiry, as the pilot could not be reached for questioning and appeared to have left the country. Investigators reviewed the aircraft's maintenance history, noting that the most recent Mandatory Periodic Inspection (MPI) had been completed on 23 August 2006. At the time of the accident, the airframe had accumulated an additional 97 hours since that inspection. Records confirmed that the maintenance organization responsible for the MPI held a valid approval at the time of the occurrence. Meteorological reports indicated favorable flying conditions, with visibility reported as CAVOK.
Findings
- The primary factor in the accident was the loss of directional control during the landing sequence.
- The aircraft sustained structural damage to the propeller and the nose landing gear assembly.
