What happened
During a scheduled calibration mission, the crew departed from Salvador-Dois de Julho Airport. After completing flight operations over the ocean, the aircraft began its return journey toward Salvador. While maintaining an altitude of 1,500 feet, the right engine experienced a failure. In response to this emergency, the crew initiated a descent and decided to divert to the closest available airfield.
As the aircraft descended to 800 feet, the left engine also ceased functioning. Facing a total loss of power, the crew performed an emergency ditching in the waters near Itaparica. Although both pilots managed to swim to the coastline following the impact, the aircraft subsequently sank and was destroyed. There were zero fatalities reported among the crew, though the vessel was lost.
Findings
Investigations into the incident identified that the primary factor was a double engine failure occurring in rapid succession during the descent.
