Airworthiness Directives (AD)
Course Overview
This course provides a clear, practical understanding of Airworthiness Directives (ADs)—the legal mechanisms used to correct unsafe conditions in aircraft, engines, propellers, and appliances. You’ll learn how ADs are created, classified, implemented, and tracked across different authorities, and how maintenance organisations integrate AD compliance into continuing airworthiness.
Learning Objectives
- Define airworthiness and explain what an Airworthiness Directive is.
- Understand the global regulatory framework (ICAO, FAA, EASA) governing ADs.
- Describe the AD issuance process and stakeholder roles (authorities, manufacturers, operators).
- Discuss challenges and evolving technologies related to RVSM.
- Interpret the structure and key terminology used in an AD and identify mandatory actions.
- Apply compliance, recording, and tracking practices within maintenance records and systems.
- Distinguish ADs from Service Bulletins (SBs) and Safety Information Bulletins (SIBs).
- Integrate AD management into CAMO/Part-145 procedures and responsibilities.
- Explore future trends: digital ADs and predictive airworthiness using data/AI.
- Analyse real case studies to connect regulation with operational practice.
