What happened
On 18 June 2024, a Samba UFM-10 aircraft, registration ZU-CUD, was performing a private flight departing from New Tempe Aerodrome in the Free State. The flight, conducted under visual meteorological conditions, initially proceeded without incident after departing Runway 01. However, during the return to the same aerodrome, the aircraft experienced a significant landing error.
While on final approach, the aircraft was traveling at approximately 65 knots. During the flare maneuver, the aircraft ballooned, causing the pilot to miss the intended touchdown point. The aircraft subsequently landed deep on the runway with a heavy impact on the nose gear. The force of the landing caused the nose gear strut to collapse and break away from the airframe. The impact also caused the propeller to strike the runway surface, resulting in one blade breaking off and damage to the remaining two blades. The engine cowling also sustained damage during the sequence. The pilot was able to exit the aircraft unassisted, and there were 0 fatalities and 0 injuries.
The investigation
SACAA AIID examined the flight parameters and the mechanical state of the aircraft. The investigation confirmed that the pilot held a valid National Pilot Licence and was qualified to operate the aircraft type. The aircraft's maintenance records showed a valid Certificate of Release to Service, and the aircraft possessed a valid Authority to Fly. The investigation also reviewed the manufacturer's operating handbook, which specifies that the required approach speed is 59 knots and the touchdown speed should be approximately 37 knots.
Findings
- The primary cause of the accident was that the aircraft's airspeed was too high during the approach phase.
- This excessive speed led to the aircraft ballooning and subsequently bouncing during the flare.
- The resulting hard landing on the nose gear led to the structural failure of the nose gear strut.
- Weather conditions were good and were not a contributing factor to the event.
- There was sufficient fuel on board for the intended flight.
