A Beechcraft E90 King Air was destroyed after impacting terrain near Sotillo de las Palomas in Spain.
The aircraft had taken off from Madrid-Cuatro Vientos Airport, Spain on a flight to Cascais Municipal Aerodrome in Portugal. All four occupants have died.
When climbing from FL190 to FL210 the aircraft stalled and entered a spin, which developed into a flat spin.
Stresses on the fuselage caused the tail to break up.
Causes/ Contributing factors:
The investigation has concluded that this accident was caused by the loss of control of the aircraft in flight due to a stall and subsequent spin. Due to the high degree of destruction of the aircraft's wreckage after the ground impact and subsequent fire, and the lack of other pertinent data to do so, it has not been possible to determine with precision the sequence of the process leading
to the aircraft stall/spin.
The investigation identified the following contributing factors:
- The decision to make the flight with adverse meteorological conditions (IMC) along the planned route, considering the fact that the weather radar was not operational.
- The forecast of moderate to strong icing conditions in areas of the route (presence of cumulonimbus with caps of up to 35,000 feet and with temperatures between -17°C and -19°C at flight level FL180) suggests that the formation of ice or its accumulation on the aircraft has been a significant contributory factor in this accident
- The use of the autopilot and the failure to disengage it when the emergency situation arose, as it is concluded from the detailed analysis of the radar data, could have contributed significantly to the process that resulted in the loss of control of the aircraft.
- The inadequate training of the pilot (who lacked the type rating for the accident aircraft) in abnormal or emergency situations on the accident aircraft.
