## CS 26.302 Fatigue and damage tolerance evaluation

Compliance with point 26.302 of Part-26 is demonstrated by complying with CS 25.571 Amendment 19, or subsequent amendment, or with points (a) or (b) of this CS:

(a) For aeroplane structures certified on the basis of JAR 25.571 Change 6 or 14 CFR §25.571 Amendment 44 or equivalent, or earlier amendments, a fatigue and [damage tolerance evaluation](https://avioverse.aero/glossary/easa/damage-tolerance-evaluation) according to JAR 25.571 Change 7 or 14 CFR §25.571 Amendment 45 or equivalent, or later amendment, exists, except that residual strength loads may be based upon the fail-safe load cases of the original certification basis. In addition, the inspection and other procedures resulting from this evaluation:

(1) are contained in an existing ALS; or

(2) are contained in a supplemental structural inspection document (SSID) mandated by an airworthiness directive (AD).

In both cases, the documentation includes the time in flight cycles, flight hours or another relevant measure by which the actions within the ALS/SSID are implemented.

(b) For aeroplane structures certified on the basis of JAR 25.571 Change 7 or 14 CFR §25.571 Amendment 45 or equivalent, or later amendments: the inspections or other procedures resulting from the DTE required by that certification basis are included in the ALS.
