Airworthiness Directives (ADs) are legally enforceable regulations issued by the FAA to correct unsafe conditions in aircraft and aircraft components.
Types of Airworthiness Directives
- Emergency ADs: Issued immediately when an urgent safety issue is identified
- Proposed ADs: Published for public comment before final rulemaking
- Final Rule ADs: Become effective after the comment period closes
Compliance Requirements
All aircraft operators must comply with applicable ADs. Compliance methods include repetitive inspections, part replacements, design modifications, or operational limitations. Records of compliance must be maintained in the aircraft maintenance log.
Tracking AD Compliance
Use digital maintenance tracking systems to monitor AD status across your fleet. Subscribe to FAA AD notifications and review Service Bulletins from OEMs to stay ahead of regulatory changes.
