What happened

On 28 July 2019, the pilot of a Van’s RV-6A aircraft, registered VH-ANU, conducted a private flight from Coober Pedy to William Creek aircraft landing area, South Australia. After touching down with the main gear first, the nose gear touched the runway momentarily. The pilot noted that although the nose gear lifted off after touchdown, the main gear stayed on the runway.

When the nose wheel made contact with the runway surface for the second time, the nose gear bent under the aircraft. The propeller struck the runway and the aircraft skidded on its nose, then flipped over and came to rest inverted.

The pilot sustained serious injuries and the passenger minor injuries. The aircraft was substantially damaged.

What the ATSB found

The ATSB found that during the landing sequence, the ground clearance of the nose gear fork or strut was reduced sufficiently to allow them to contact the runway surface. This initiated the damage to the nose gear and resulted in the aircraft becoming inverted.

Safety message

A reduction in the nose gear ground clearance during landing can result in the nose gear strut or fork impacting the runway and affect the structural integrity of the nose gear. In the tricycle variants of Van’s aircraft, the factors that can affect nose gear ground clearance include the dynamics of the landing, tyre pressure, weight over the nose gear, and runway condition and characteristics.

After-market devices fitted to this aircraft aimed at reducing the risk of a nose-gear collapse and aircraft inversion, did not prevent the accident.
