Circumstances:
On final approach to Asunción-Silvio Pettirossi Airport, the crew encountered marginal weather conditions with limited visibility. The four engine aircraft was too low, hit trees and struck the ground. On impact, the undercarriage were sheared off and the airplane slid for several yards before coming to rest in a wooded area. A crew member and a passenger were killed while all 48 other occupants were evacuated, some of them wounded. The aircraft was written off.
Probable cause:
The crew led the aircraft pass below the glide in marginal weather conditions and continued the approach at an insufficient altitude, against published procedures.

Circumstances:
While in cruising altitude, the engine number four oversped. The engine was shut down and the propeller was feathered. A little later, the engine number two suffered severe vibrations and it was also decided to shut it down and to feather its propeller. Due to insufficient power, the aircraft started to descend with a rate of 500 feet per minute. The captain eventually decided to attempt an emergency landing on Ilha Grande. The airplane belly landed on a beach and came to rest. All 22 occupants were uninjured.
Probable cause:
Double engine failure for undetermined reason.

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 airplane departed Buenos Aires at 0515LT bound for Río Cuarto. Less than two hours into the flight, the crew contacted Río Cuarto and was informed about poor weather at destination. Despite conditions below minima, the pilot decided to start an IFR descent when the airplane struck the slope of a mountain and disintegrated on impact, killing all 18 occupants.
Probable cause:
The decision of the pilot to descend en route, without justifiable reason, below the minimum altitude prescribed for a night flight, and in weather conditions which made it his duty to follow IFR procedure a contributing cause probably being an error between control tower and aircraft in the transmission or interpretation of barometric pressure of QFE and QNH values.

Circumstances:
The aircraft was performing a charter flight from Buenos Aires to Ushuaia with intermediate stops in Bahía Blanca and Comodoro Rivadavia, carrying 20 members of the Argentinian Sports Confederation and a crew of three. Due to sufficient fuel reserve, the captain decided to cancel the fuel stop in Bahía Blanca and continued directly towards Comodoro Rivadavia. While approaching Trelew, he encountered foggy conditions and decided to return to Bahía Blanca as Comodoro Rivadavia was also in fog. Due to low visibility, he lost his orientation and flew over the sea before flying back overt the continent. Few minutes later, both engines failed due to fuel exhaustion. He reduced his altitude and attempted an emergency landing in a prairie located near Juan A. Pradere. After touchdown, the airplane hit trees and bushes about 2 meters high, swung and came to rest with its right wing torn off to the engine. All 23 occupants evacuated safely while the aircraft was considered as damaged beyond repair.
Probable cause:
Double engine failure caused by a fuel exhaustion.
