Italian Air Force Cargo Aircraft Crash During Initial Climb (I-LUPI)

Barcelona, SpainTakeoff (climb)

On May 16, 1940, a Savoia-Marchetti SM.75 (registration I-LUPI) operated by Ala Littoria was involved in an aviation accident near Barcelona, Spain during takeoff. 8 people were killed. Investigators recorded the probable cause as: Cargo shifted to the rear during rotation, altering the center of gravity and causing the aircraft to become uncontrollable. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 8 related events involving the same aircraft type or operator are linked below.

A three-engine cargo plane operated by the Italian Air Force crashed shortly after takeoff due to a shift in cargo weight, resulting in the deaths of all eight people on board.

What happened

The incident occurred during the initial climb phase, shortly after the aircraft had rotated for takeoff. The three-engine airplane experienced an uncommanded nose-up pitch attitude, which led to an aerodynamic stall. Consequently, the aircraft crashed onto the runway surface and immediately caught fire. All eight occupants perished in the accident. At the time of the crash, the aircraft was operating on behalf of the Italian Air Force (Aeronautica Militare Italiana) and was en route back to Italy.

Findings

Investigations determined that the primary factor leading to the loss of control was a significant shift in the cargo load. During rotation, the freight moved toward the rear of the fuselage. This movement altered the aircraft's center of gravity, creating an unstable condition that rendered the airplane uncontrollable and resulted in the crash.

Probable cause

Cargo shifted to the rear during rotation, altering the center of gravity and causing the aircraft to become uncontrollable.
