Once the crack reaches a "critical size," the material can no longer support the load, leading to a sudden, often warning-less break. Primary Causes of Cracking
Understanding why these cracks form and how to detect them is the difference between routine maintenance and catastrophic failure. What are FLT Cracks? flt cracks
Modern aircraft like the Boeing 787 and Airbus A350 utilize carbon-fiber reinforced composites rather than aluminum. Composites handle fatigue differently and are generally more resistant to the cyclic stress that plagues metal. However, they introduce new challenges, such as delamination, requiring new inspection techniques. Once the crack reaches a "critical size," the
