Circumstances:
The seaplane left Buenos Aires harbor at 1152LT bound for Asunción with intermediate stops at Rosario, Corrientes and Formosa. Few minutes after takeoff, the captain encountered oscillations and difficulties to control the airplane so he decided to return to Buenos Aires for a safe landing. Unfortunately, it was not possible to land immediately because of the presence of ship in the channel. Following several circuits, the pilot-in-command attempted to land when the airplane crashed into the sea few hundred yards off shore. A crew member and eight passengers were killed while 41 other occupants were injured. The aircraft was destroyed.
Probable cause:
The accident was probably caused by a premature withdrawal of the flaps, a trend exacerbated by abnormal conditions affecting the airworthiness of the seaplane, particularly evident in the approach procedure, and a concurrent cause of inadequate maintenance of the aircraft, and the failure in the process of clearing the elevator control, established by seaplane maintenance manual.

Circumstances:
The aircraft took off from Ezeiza Airport at 1554LT on a scheduled flight direct to San Carlos de Bariloche with Comodoro Rivadavia as alternate. Six crew and fifty-five passengers were aboard. Clearance was granted by the Regional Centre Control Area for an IFR flight outside airways, with 1 200 metres as safety height as far as Neuquén and 2 400 metres up to the destination aerodrome. The aircraft carried out routine communications with the airport control tower and with the approach control office until it reached Lobos, where it was authorized to use telegraphy. From that moment there was no further information available concerning the flight. It was later established that at 1645 hours the aircraft had crashed 25 km southeast of Bolivar. All occupants were killed and the aircraft was destroyed by the impact and the fire which broke out subsequently.
Probable cause:
The aircraft disintegrated in flight due to breakage of parts of the left wing followed by the falling off of the tail section when the equipment was subjected to stresses above those envisaged by the manufacturer. This was brought about as a direct result of the pilot's decision to attempt to cross a cold surface front under turbulent conditions of extreme severity. The following were contributing causes:
- The pilot's recklessness in descending on a track well below the minimum safety flight altitude established for this type of operation,
- The absence in the flight plan of a forecast showing the intensity of the meteorological phenomena encountered,
- Inadequate ope rational dispatch of the aircraft.
