Seconds after lift-off, the left engine lost power, and a minute later the crew issued a mayday call, requesting to return immediately to the airport.

[2] The Turbolet climbed to 400 ft while turning to position itself for a landing on the opposite runway 36, but it subsequently started losing altitude.

At 06:54, shortly after the crew announced their intention to attempt an emergency landing on the beach, the aircraft stalled and crashed into an open area of Boa Viagem, between Visconde de Jequitinhonha and Boa Viagem Avenue, approximately 2 km (1.2 mi; 1.1 nmi) from the end of the runway.

[6] While twin-engine aircraft are normally capable of flying with one engine inoperative, the report identified several factors that prevented the Turbolet from maintaining altitude and speed, including a 130 kg (290 lb) exceedance in the maximum take-off weight resulting from an error in the software used by the flight dispatcher, the insufficient application of right rudder by the pilot flying, and the incomplete execution of the recommended emergency procedure for engine failure at take-off.

The CENIPA made several safety recommendations to Noar and Let to address such issues, and also to GE Aviation, the owner of engine manufacturer Walter, to "reevaluate the method utilized for the exam of the blades.
