Air Caraïbes Flight 1501 (TX1501/FWI1501) was a scheduled international passenger flight, flying from Saint Martin Airport in the Dutch overseas territory of Sint Maarten to Saint Barthélemy Airport which was in the French overseas region of Guadeloupe at that time. The flight was operated by Air Caraïbes, a Caribbean regional airline, using a de Havilland Canada DHC-6-300 Twin Otter. On 24 March 2001, during an approach to Saint Barthélemy Airport, the DHC-6 Twin Otter banked steeply to the left and crashed into a house, killing all 19 passengers and crew on board. One person on the ground was also killed in the explosions that followed.
