What happened
Following departure from the airport, the aircraft failed to establish a positive climb rate. Unable to gain sufficient altitude, the machine struck the roof of a house before stalling and descending into a factory complex located in Le Blanc-Mesnil, southeast of the airfield. The impact resulted in a fire that engulfed the wreckage.
Of the twenty-six people on board, seven individuals, consisting of one crew member and six passengers, were successfully rescued from the scene. Tragically, nineteen other occupants lost their lives in the accident. Additionally, one person on the ground was killed as a result of the crash. The deceased crew members included the pilot, a radio navigator, a mechanic, and a stewardess.
Findings
Official investigations indicated that both engines were not producing full power during the takeoff phase. This lack of thrust resulted in insufficient speed and lift, preventing the aircraft from gaining altitude after leaving the ground. Despite extensive inquiry, investigators were unable to determine the specific mechanical or operational reason for the engine power deficiency.
