The approach to Cayaya Airport was initiated in heavy rain falls and limited visibility. On short final, the airplane was too low and the right wing struck the ground and was torn off. Out of control, the airplane crashed onto the runway and came to rest. All four crew members escaped uninjured while the aircraft was destroyed.
Probable cause (official findings): Error on the part of the pilot in deciding to land in adverse weather conditions. The lack of assistance from ATC personnel at the airport was considered as a contributing factor.
