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).

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.
