Widerøe Flight 839 crashes after takeoff from Værøy Airport in Norway, killing five people.

Widerøe Flight 839, also known as the Værøy Accident, was a de Havilland Canada DHC-6-300 Twin Otter that crashed shortly after takeoff from Værøy Airport in Værøy Municipality in Lofoten, Norway. The accident occurred on 12 April 1990 at 14:44, killing all five people on board. The cause of the accident was strong winds that exceeded the structure's tolerance, causing the tail rudder and tailplane to crack and the aircraft to become uncontrollable. Impact occurred 63 seconds after takeoff and 8 seconds after the crack. The aircraft crashed into the water and a search was conducted for several days to locate the wreckage.

Værøy Airport was a regional airport located just southwest of the village of Nordland on the island of Værøya in Værøy Municipality in Nordland county, Norway. Operated between 1986 and 1990, it had an 800-by-30-meter asphalt runway aligned 07–25. The airport was owned and operated by the Værøy Municipality. It was served by Widerøe, who operated de Havilland Canada DHC-6 Twin Otter aircraft to the town of Bodø and the nearby island of Røstlandet. After a fatal accident in 1990, the airport was shut down.
