One of the time-honored conventions of aviation journalism is that every article about metal fatigue has to start with mention of the “ill-fated Comet.”
That requirement has now been met.
When Airplanes Feel Fatigued
Key Takeaways:
- Metal fatigue is a long-understood phenomenon where repeated stresses cause materials to fail at loads far below their ultimate strength, often accumulating invisibly until sudden, catastrophic cracking occurs.
- Unlike corrosion, fatigue is difficult to detect, manifesting without warning, leading to a false sense of security in older aircraft that have not yet shown visible signs of cracking.
- The issue of metal fatigue is projected to become more prevalent in the future due to an aging civil aviation fleet, increased aircraft utilization, the repurposing of ex-military aircraft for demanding roles, and the ongoing administrative challenge of balancing safety risks with remediation costs.
