What happened
On 9 September 2007, a Cessna 172 K, registration ZS-FUD, was conducting private flight training exercises at Grand Central Aerodrome. The pilot, who had not flown for four weeks, intended to perform circuit and landing practice. After completing the first circuit and receiving landing clearance for runway 35, the pilot approached the runway at an indicated airspeed of 70 mph.
While the touchdown initially appeared normal, a sudden gust of wind from the right side caused the right wing to lift. This wind event caused the aircraft to veer sharply to the right. Despite attempts to apply corrective action, the aircraft drifted off the runway surface. The right wing struck a perimeter fence pole, and the momentum of the aircraft carried it through the fence, where it eventually came to a stop facing west. There were no injuries to the pilot, though the aircraft sustained substantial damage to its propeller, fuselage, right wing, and wheel spats.
The investigation
SACAA AIID investigators examined the circumstances surrounding the loss of control. The investigation confirmed that the aircraft was in a serviceable condition, with all mandatory inspections up to date and no mechanical defects contributing to the event. The brakes were also tested post-accident and found to be fully functional.
Investigators noted that the pilot had only obtained his private pilot's licence one hour prior to the accident. The meteorological data at the time showed a 9-knot wind from 050°, which was within the manufacturer's demonstrated crosswind limits, though the sudden gust proved critical.
Findings
- The pilot was operating with a valid private pilot's licence and appropriate type endorsement.
- The accident was precipitated by a sudden gust of wind that caused the aircraft to lose directional control.
- The pilot's recent lack of flight activity (four weeks) and limited experience in handling crosswind landings contributed to the inability to recover the aircraft's path.
- The aircraft's speed decay likely rendered rudder corrections ineffective during the excursion.
