Report on aircraft accident at Ålesund airport Vigra, Norway on 2 May 2016 with Van's RV-4, LN-AAR

On 2 May 20016 LN-AAR landed at Ålesund airport, Vigra. Shortly after landing the aircraft encountered a slight rotation towards the left. As the rotation became more evident the main wheel turned about 90 degrees in comparison to the aircraft direction, and the landing gear which is part of the engine mount collapsed. The landing ended up in a "ground loop". No one was injured in the accident. The Norwegian Safety Investigation Authority believes that the probable cause of the ground loop is a combination of the initial rotation to the left and crosswind. It is the Norwegian Safety Investigation Authority´s view that the landing gear collapsed as a result of overload due to the aircraft´s rotation to the left and ground loop. However, it cannot be ruled out that the engine mount combined with the landing gear attachment had an inherent weakness in the form of local material deformation or similar, after previous overload, where this last landing triggered a fracture.

This report is in Norwegian only.

No safety recommendation is issued in connection with this investigation.
