A twin-engine aircraft crashed into an open field near Senlis while descending to Paris-Le Bourget Airport in marginal weather, resulting in the deaths of all five people on board.

What happened

The incident occurred during a descent phase toward Paris-Le Bourget Airport under marginal weather conditions. The flight crew failed to recognize that the aircraft was flying at an altitude too low for safe approach. Consequently, the twin-engine machine impacted the ground in an open field located in Senlis, approximately 30 kilometers northeast of the airport.

Upon impact, the airframe sustained severe structural damage, with both wings partially detached from the fuselage. The cockpit area was destroyed, while the passenger cabin remained relatively intact. Tragically, the accident resulted in fatal injuries for everyone on board. Two passengers and all three crew members were killed in the crash.

Findings

The primary contributing factor identified in the sequence of events was the crew's failure to detect that they were flying too low during the descent. This lack of situational awareness, combined with the marginal weather conditions at the time, led directly to the controlled flight into terrain event.

Probable cause

The crew failed to realize the aircraft was flying too low during descent in marginal weather, leading to a ground impact.
