Iberia Flight 1456 was a domestic scheduled flight from Barcelona-El Prat Airport to Bilbao Airport, Spain. On Wednesday, February 7, 2001, the Airbus A320 encountered a microburst-induced wind shear on final approach leading to the collapse of the aircraft's landing gear. All 143 passengers onboard survived; with 24 people suffering light injuries, and 1 person receiving serious injuries. The aircraft was irreparably damaged and was decommissioned, making it the ninth loss of an Airbus A320 at that time. This accident prompted Airbus to develop a fail-safe modification for its flight control software by preventing the airplane's built-in protection against stall from being activated by a high rate of change for the angle of attack.
