Every FAA Airworthiness Directive since 2018, one page each, with the parts it names

An Airworthiness Directive is the FAA telling operators that something on a type of aircraft must be inspected, replaced or modified by a date. The Federal Register publishes them as legal text. We have been loading them daily since Tuesday to flag directives that name parts our sellers list; today they get pages of their own.

What is on an AD page

• The requirement in plain language, the effective date, the docket and citation, and a link to the full rule.
• The applicability text: which models, which serial ranges.
• Every part number the directive names, extracted from the text: 1,867 of the 3,115 directives name at least one, 6,256 part numbers in all. For each, the NSN cross-reference where we hold one (426 do), how many sellers list it here, and whether DLA has an open request for it.
• The proposed rule that preceded it, the directive it supersedes, any directive that has since superseded it, and the manufacturer's other recent directives.

Start at /ad for the newest final rules and the manufacturers with the most directives in the last two years, or go straight to one: AD 2026-18-10. Directives named on a stock-number or part page now link here.

Watch a part number on its page and we email you when a new directive or a service difficulty report names it. That has been true since Tuesday; now the email has somewhere useful to point.
