Double Engine Failure During Initial Climb Results in Fatal Crash (PP-SAC)

Pelotas, BrazilTakeoff (climb)

On January 11, 1949, a Lockheed 18 LodeStar (registration PP-SAC) operated by Sociedade Anônima Viação Aérea Gaúcha - SAVAG was involved in an aviation accident near Pelotas, Brazil during takeoff. 8 people were killed. Investigators recorded the probable cause as: Simultaneous engine failure caused by fuel contamination during the initial climb phase. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 2 related events involving the same aircraft type or operator are linked below.

An aircraft crashed near the runway end shortly after takeoff when both engines failed during the initial climb, resulting in the deaths of all eight occupants on board.

What happened

The incident occurred immediately following departure from the runway. As the aircraft entered the initial climb phase, a critical mechanical failure manifested when both engines ceased functioning. The loss of thrust caused the airframe to lose altitude rapidly, leading to an aerodynamic stall. Unable to recover control or regain sufficient speed, the machine impacted the ground in close proximity to the end of the runway.

The crash was fatal for everyone on board. All eight occupants perished in the accident. There were no survivors reported from the event.

Findings

Investigations into the root cause of the dual engine failure pointed toward issues with the fuel supply system. Official findings indicate that fuel contamination is believed to be the primary factor responsible for the simultaneous loss of power in both engines, which ultimately led to the fatal outcome.

Probable cause

Simultaneous engine failure caused by fuel contamination during the initial climb phase.
