What happened
The incident occurred shortly after the aircraft departed from Shell-Mera Airport. During the initial climb or early cruise phase, the pilot encountered deteriorating meteorological conditions described as very bad weather. As the seaplane approached the valley associated with Baños de Agua Santa, it struck the slope of a mountain. The impact resulted in the total destruction of the airframe. All five occupants on board were killed in the accident.
Findings
The primary factor leading to the collision was the pilot's encounter with severe weather conditions immediately following departure. These adverse meteorological circumstances likely impaired visibility or control, culminating in the controlled flight into terrain (CFIT) event where the aircraft impacted the mountainside.
