The threshold for initial NDI is defined as the flight cycles at which the crack length reaches 0.5 mm for eddy current or 1.27 mm for ultrasonic A-scan. The inspection interval (I) is:
[ I = \fracN_a_crit - N_a_detect2 ]
Where ( N_a_crit ) is cycles to reach critical crack length (a_crit) defined by residual strength requirement: ( K_Ic \geq \sqrt \pi \cdot a_crit \cdot \beta \cdot \sigma_max )

It is common for professionals and students to search for a "free PDF" download of the manual. However, there are important factors to consider regarding free versions found on the internet:
To appreciate why this document is so sought after, here is a glimpse of what you get when you successfully download the official "EASA Technical Manual PDF Free" from the Easy Access Rules portal.
Module 1 – Mathematics: Arithmetic, algebra, geometry. Module 2 – Physics: Mechanics, thermodynamics, optics. Module 3 – Electrical Fundamentals: Electron theory, AC/DC circuits. Module 5 – Digital Techniques: Electronic instrument systems, logic circuits. Module 6 – Materials & Hardware: Aircraft materials, corrosion, fasteners. Module 7 – Maintenance Practices: Safety, riveting, composite repairs. Module 8 – Basic Aerodynamics: Airflow, high-speed flight. Module 9 – Human Factors: SHEL model, fatigue, error management. Module 10 – Aviation Legislation: EASA framework, certifying staff rules.
Each of these modules is technically a chapter of the entire AMC/GM document. The free EASA version is text-heavy but complete. The paid versions add diagrams and sample questions.
