A Germanwings Airbus A320 flying from Barcelona to Düsseldorf crashed in the French Alps on March 24, 2015, killing all 150 people on board. The aircraft, operating as Flight 4U9525, descended into a mountain in the commune of Prads-Haute-Bléone after losing contact with air traffic control. French investigators later determined the co-pilot deliberately locked the captain out of the cockpit and set the autopilot to descend.
Key Facts
- Germanwings Flight 4U9525, an Airbus A320 registered D-AIPX, crashed in the French Alps on March 24, 2015, killing all 150 people on board.
- The aircraft departed Barcelona at morning and was en route to Düsseldorf when it began an unauthorized descent and struck a mountain near Prads-Haute-Bléone.
- French investigation bureau BEA concluded that the co-pilot deliberately locked the cockpit door, set the autopilot to descend to about 100 feet, and ignored the captain's attempts to re-enter.
- Among the passengers were 16 schoolchildren and two teachers from Haltern am See, Germany, returning from a trip to Spain.
Crash Sequence
Flight 4U9525 took off from Barcelona Airport on the morning of March 24, 2015, with 144 passengers and six crew members aboard. After reaching cruise altitude, the aircraft began a gradual descent without responding to air traffic control calls. The Airbus A320 struck a mountain slope in the commune of Prads-Haute-Bléone in the Alpes-de-Haute-Provence department. The crash site was in difficult mountainous terrain, which complicated rescue and search operations.
Investigation Findings
The French Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA) led the investigation and recovered the flight recorders. Data showed that after the captain left the cockpit, the co-pilot locked the door from inside and did not respond to the captain's attempts to re-enter. The co-pilot set the autopilot to descend to approximately 100 feet and repeatedly adjusted it to increase the rate of descent. BEA concluded the crash was a deliberate act by the co-pilot, citing intentional collision with terrain as the primary cause. The investigation also identified deficiencies in pilot psychological screening and unclear rules on when medical confidentiality should yield to public safety.
