Beschrijving:
A Cessna 208B Grand Caravan, registered, HC-BXD, was destroyed when it crashed into a building shortly after takeoff from Cuenca-Mariscal Lamar Airport (CUE).
The airplane had arrived at Cuenca at 10:18 after an uneventful flight from Macas (XMS). The Cessna 208B was prepared for the return flight to Macas and twelve passengers boarded the flight with 240 lb (109 kg) of baggage. Startup was approved at 10:57 and the airplane taxied to runway 05 for departure. The flight was airborne at 10:59, reaching a height of 300 feet. After passing the end of the runway, the airplane began to descend rapidly. The nose wheel hit the roof of a building from the Compañía Ecuatoriana del Caucho rubber processing company. The Cessna struck a wall and came to rest nose-down.
