During laser scanning of a power line 21 June 2018, the helicopter main rotor hit a crossing power line. Three conductors on the 110 kV line were cut, but the helicopter made a safe landing at the nearby airport Gullknapp (ENGK).
None of the two persons onboard were injured, and the helicopter was only substantially damaged. The incident will be seen in conjunction with a similar incident that occurred on January 18, 2018, where a helicopter, LN-OST, was close to hitting a crossing power line during powerline inspection.
AIBN made one recommendation on marking crossing wires.
