Narrative:
The Sikorsky S-43B flying boat was operating on an international service from Miami, FL to Rio de Janeiro, Brazil with en route stops at Antilla, Port-au-Prince, San Pedro de Macorís, San Juan, Port of Spain, Georgetown, Paramaribo, Cayenne, Bélem, São Luís, Fortaleza, Natal, João Pessoa, Recife, Maceió, Aracaju, Salvador, Caravelas and Vitória.
The flight was circling Rio de Janeiro for a normal approach when the left engine lost power. The airplane yawed to the left and started a descending turn. The turn became sharper and the airplane descended at a steeper angle until it struck a caisson at Ilha das Cobras, in Guanabara Bay and crashed.

PROBABLE CAUSE: "Loss of power from the left engine during landing approach necessitating an attempted landing under extremely hazardous conditions."
