What happened
While performing a takeoff roll on runway 26, the Douglas DC-4 experienced a loss of control at an indicated airspeed of 61 knots. During the maneuver, the aircraft swerved toward the left side of the runway and exited the paved surface. The plane subsequently struck multiple obstacles and descended down an embankment.
The impact caused the airframe to break into several pieces. Following the collision, a post-crash fire erupted near Route Nationale 7, which ultimately destroyed the aircraft. There were three injuries reported among the crew members on board, with no fatalities recorded.
Findings
Investigations determined that the loss of control was triggered by an engine malfunction. This mechanical issue originated from a configuration error made by the flight engineer. Specifically, the main fuel selectors were left in a 'half-on' position. This particular setting incorrectly indicated an 'On' status for five of the operator's Douglas DC-4 fleet, leading to the critical failure during the takeoff phase.
