On 5 April 1986, at 13:26, an Eagle Air Piper PA-23-250 Aztec light aircraft crashed in Ljósufjöll in Snæfellsnes, Iceland killing five of the occupants on board.

[7] The wreckage of the plane was found on the northern slopes of Ljósufjöll, at an altitude of 700 metres (2,300 ft), just before midnight the same day.

[8][9] An investigation by the Air Accident Committee and the Civil Aviation Administration concluded that the plane likely landed in a downdraft resulting in it crashing into the slopes of Ljósufjöll.

It also concluded that a large part of the cause was due to the pilots lack of access to current weather information in the area.

[10] The accident and investigation resulted in changes on aviation regulations and procedures to increase the flow of up-to-date weather information between pilots and the Icelandic Meteorological Office.
