What happened
On April 13, 2018, a Cessna 172P, registration LN-RAB, operated by Tynset Flyklubb, was performing a private flight from Frya Airport to Tynset Airport. During the approach to runway 05, the pilot followed a standard right-hand pattern. As the aircraft passed the runway threshold, the pilot noted the plane was flying too high. Although considering a go-around, the pilot decided to proceed with the landing and pushed the nose down to descend.
The aircraft touched down with approximately 400 meters of runway remaining. Upon contact with the surface, the aircraft encountered an icy patch that reduced braking effectiveness. The pilot reported a sensation of the tail lifting, which was initially attributed to a wind gust. Simultaneously, the aircraft lost directional control and began veering to the left. Despite rudder corrections, LN-RAB drifted off the runway and struck the left snowbank. The impact caused the aircraft to stop abruptly, tilting forward and sideways, which resulted in the right wing striking the ground and bending upward. The pilot, who was the sole occupant, escaped without injury.
The investigation
The Norwegian Safety Investigation Authority (NSIA) examined the aircraft's tracks on the runway, which showed lighter impressions from the right main wheel. This pattern is consistent with the phenomenon known as "wheelbarrowing," where excessive weight is transferred to the nose wheel, reducing the stability and braking capacity of the main gear. The investigation also reviewed the pilot's flight experience and the environmental conditions, noting the presence of ice on the runway.
Findings
- The pilot attempted to land an unstable approach rather than executing a go-around.
- The pilot's decision to force the nose down to compensate for high altitude likely induced wheelbarrowing, which compromised directional stability.
- An icy section of the runway significantly degraded braking performance.
- The aircraft sustained damage to the right wing, propeller, and landing gear.
