The DHC-6 Twin Otter 300 sustained substantial damage when it crashed in a forest near Tamarindo Airport, Costa Rica.
The aircraft operated on a flight from San José to Tamarindo and Liberia, Costa Rica.

The Twin Otter was bought by CAAMS LLC in the U.S. to be completely refurbished, but the registration N805WJ expired in 2018.

Probable Cause:

Contributing Factors:
- The cable of the elevator that possibly burst due to progressive wear with a damaged pulley.
- The nearness of the Terrain
- The low speed of the aircraft
- Lack of crew training for this type of emergency.
- The loss of control of the aircraft in a critical phase of the flight, the landing, initially by a mechanical failure and later to human factors.
