Which agency issues Airworthiness Directives (ADs)?

Airworthiness Directives are regulatory actions that address unsafe conditions in aircraft, engines, or propellers. The agency that issues these directives is the Federal Aviation Administration. The FAA has authority to identify an unsafe condition and require actions—such as inspections, repairs, or modifications—within a specified timeframe. These directives are mandatory and legally enforceable for operators and maintenance facilities. Other agencies, like the NTSB, investigate accidents and issue safety recommendations; NASA conducts research; and while the DOT oversees the FAA, it is the FAA itself that issues the directives. A manufacturer’s service bulletin may recommend fixes, but an AD is the formal, enforceable directive issued by the FAA.
