   • Cause: The crash was attributed to the failure of the engine pylon structure due to improper maintenance procedures.

2. American Airlines Flight 587 (November 12, 2001):

   • Incident: An Airbus A300-600 crashed into the Atlantic Ocean shortly after taking off from John F. Kennedy International Airport in New York, killing all 260 people on board.
