Probable cause:
The loss of control during initial climb was the consequence of the combination of the following factors:
- Poor flight preparation on part of the crew,
- Inadvertent shutdown of the left engine during initial climb for unknown reasons,
- The left propeller was not feathered, causing high drag,
- The flaps were not deployed in the correct position for takeoff,
- The CofG was off limits,
- Negligences of those responsible for planning and safety in the air transport of important figures of State, in an aircraft of foreign registration whose maintenance status was not previously maintained rated,
- Crew fatigue,
- Crew psychic stress accumulation.
