General Approach to WFD · To ensure the continued structural airworthiness of ageing aircraft: - The operators are required to undertake a program of modification or replacement of structure susceptible to MSD/MED, before the LDC (Large Damage Capability) of the structure is compromised - A series of directed inspections of the susceptible structure may be introduced into the operator’s maintenance schedule - This program of special inspections for MSD/MED must end at the Structural Modification Point (SMP), beyond which no aircraft may be operated unless the structure has been modified or replaced. · It is extremely difficult to analyze WFD using the standard methods based on the first principles of linear elastic fracture mechanics (LEFM). Therefore, more advanced methods have been explored and developed over the past few decades with the support and sponsorship of the FAA and the National Aeronautics and Space Administration (NASA) · Since fatigue cracks at multiple locations may interact, leading to subsequent crack initiation and growth, the analysis becomes more complex than the evaluation of a single isolated fatigue crack undertaken in a conventional damage tolerance assessment The challenge lies with the above methodologies is experimental validation of the proposed tools and criterion in developing a WFD assessment approach. The methodology developed must be verified and validated using experimental data to ensure its successful application to industry with ease.
