Norway's effort to replace its aged search and rescue helicopter fleet has suffered a significant setback after its newly delivered Leonardo Helicopters AW101 – the first of an eventual 16 aircraft – overturned during a ground run on 24 October.

No injuries were reported to the two crew on board, but images posted on social media show the 15.6t helicopter resting on its right-hand side, minus its main rotor blades.

The AW101 (MSN 50268) had only been handed over to the Royal Norwegian Air Force on 17 November.

No detail on the extent of the damage is available, but the Norwegian defence ministry has described it as a "serious incident" in local media.

Leonardo was not immediately available to comment.

The AW101 was scheduled to enter service in Norway in 2018.
