These match the airframe or engine model. Whether each one applies, and whether it's been complied with, depends on serial numbers, equipment and logbook entries. Applicability must be confirmed by a mechanic against the aircraft's records.
No ADs published since 1998 matched this airframe or engine model.
AI-extracted — verify against original. Matched from each AD's applicability section; ADs replaced by a later AD are left out.
