What happened
During an arrival from San José, the flight crew attempted to land on runway 02 at San Isidro de El General Airport. The runway surface was noted to be extremely wet at the time of the operation. As the aircraft decelerated, it failed to come to a complete stop before the end of the paved surface. The plane overran the runway by approximately 20 feet, exiting the airfield and striking a residential structure.
While all three crew members managed to evacuate the aircraft without injury, the collision with the house resulted in the death of one infant residing in the building.
Findings
Investigations into the accident determined that the primary reason the aircraft could not be stopped within the available runway length was due to ineffective braking performance caused by the saturated state of the runway. This difficulty in deceleration was further complicated by the fact that the aircraft was operating at nearly its maximum landing weight.
