From the Wikipedia article

The Seaplane Baby Clipper NC 16933 crash took place in Rio de Janeiro on August 13, 1939. The aircraft, owned by Pan Am, was flying Miami–Rio, with stops in the cities of Antilla, Port-au-Prince, San Pedro de Macorís, San Juan, Port of Spain, Georgetown, Paramaribo, Cayenne, Belém, São Luís, Fortaleza, Natal, João Pessoa, Recife, Maceió, Aracaju, Salvador, Caravelas and Vitória. This would be the first accident involving a Pan Am aircraft in Brazil.

Flight history

The aircraft involved was a three-year-old Sikorsky S-43B airliner registered NC16933. It had first flown in 1936, and had accumulated a total of 3,650 flight hours during its career.

The aircraft took off from Miami on a scheduled international passenger flight to Rio de Janeiro, with many stopovers across the Caribbean and South America. As it neared its destination, the aircraft circled Rio in preparation for a normal approach. As it was circling, however, the left engine lost power, putting the aircraft into a descending left yaw turn. As the yaw grew sharper, the pitch angle also steepened until the aircraft struck a caisson and crashed into Guanabara Bay, about 1 km from Rio's Santos Dumont Airport. Of the twelve passengers and four crew members, only two passengers survived.
