FAQ n.20813

When does EASA correct an AD?


After an AD has been published, there may be the need to update its content. Depending on the impact of the changes that will be included, an AD can be corrected, revised or superseded.

An AD is corrected to incorporate a non-substantive change to an AD, which does not affect compliance with the AD, e.g. a typographical error.

A corrected AD retains its AD number (including its revision status). The effective date of a corrected AD does not change.

Consequently, when in compliance with a not-corrected AD, an aircraft is automatically in compliance with the corrected one.
