Scandinavian Airlines Flight 751

Story

Scandinavian Airlines Flight 751 was a regularly scheduled Scandinavian Airlines passenger flight from Stockholm, Sweden, to Warsaw, Poland, via Copenhagen, Denmark. The McDonnell Douglas MD-81, registration OY-KHO, was piloted by Danish captain Stefan G. Rasmussen (44) and Swedish first officer Ulf Cedermark (34). On 27 December 1991, ice had collected on the wings' inner roots (close to the fuselage) before takeoff. It broke off and was ingested into the engines as the aircraft became airborne on takeoff. After both engines failed, the pilots were forced to make an emergency landing in a field near Gottröra, Sweden. All 129 passengers and crew aboard survived.The incident is known as the Gottröra crash (Gottrörakraschen) or the Miracle at Gottröra (Miraklet i Gottröra) in Sweden.AircraftThe aircraft was a McDonnell Douglas MD-81, registered OY-KHO, serial number 53003, line number 1844. It made its first flight on 16 March 1991, and was delivered soon after to SAS on 10 April 1991. At the time of the accident, the aircraft had been in service for only 9 months. It was fitted with two Pratt & Whitney JT8D low-bypass turbofan engines.AccidentThe aircraft had arrived at Stockholm-Arlanda Airport at 22:09 local time, after a flight from Zürich, on the previous evening and was parked overnight at temperatures of around 0 to 1 °C. About of flight-chilled very cold fuel remained in the wing tanks. Because of this, clear ice had formed on the upper side of the wings, but was not detected. The aircraft was de-iced with of de-icing fluid, but not checked afterwards for remaining ice by the de-icing personnel.
