What happened
While performing a flight from Salvador to Natal, an aircraft was traveling in a group alongside three other similar planes. During the cruise phase of the journey, the aircraft's tail section was struck by the propeller of a trailing aircraft within the formation. This impact caused a portion of the tail to separate from the fuselage.
Following the structural failure, the aircraft entered an uncontrolled descent. The plane crashed upon impact with the ground, which subsequently triggered a fire. There were nine fatalities among the occupants of the aircraft.
Findings
Investigations into the accident indicate that the primary factor was a mid-air collision involving the propeller of a following aircraft striking the tail of the subject aircraft during formation flight.
