The listed crash cause is weather. The twin engine aircraft departed Madrid-Cuatro Vientos Airport on a private flight to Cascais, Portugal, carrying three passengers and one pilot. One of the reasons for the flight was to repair the weather radar at a Portuguese maintenance center that specialized in this equipment. The pilot had to delay the takeoff until 1557LT due to bad weather conditions. The aerodrome of Cuatros Vietnos was in instrument conditions (IMC), which forced its closing from 0900LT until 1444LT. At 1615LT, the aircraft was en route, climbing from flight level 190 to its authorized cruise level of 210. Moments later, according to a detailed analysis of the data taken from the radar, there was a yaw to the left, and the aircraft started to turn in this direction and suddenly lose altitude. After this event, the airspeed fell quickly and gradually until the aircraft stalled. The aircraft went into a spin, which after some time turned into a flat spin. As the airplane descended out of control, and with the spin fully developped, loads were placed on the horizontal tail that exceeded the design loads, causing the tail to break up in flight into five parts before the aircraft impacted the ground. The aircraft was completely destroyed by the impact and sibsequent fire, and its four occupants were killed in the accident.

Aircraft reference details include registration N79CT, MSN LW-303, year of manufacture 1979.
