On 7 March 2017, an en-route Cessna Citation and a manoeuvring Ikarus C42 light aircraft approaching almost head-on at speeds of 240 knots and 55 knots respectively almost collided at an altitude of 3,500 feet in VMC outside controlled airspace. The Investigation found that only the C42 pilot had seen a conflicting aircraft and that they had then taken avoiding action which had mitigated the high risk of collision. The closest point of approach was recorded on radar as less than 100 feet vertically and less than 185 metres laterally. The near miss was categorised as an ICAO 'A' event.
