What is the consequence of noncompliance with Airworthiness Directives (ADs)?

Noncompliance with Airworthiness Directives (ADs) leads to the aircraft being deemed unairworthy because ADs are legally enforceable regulations issued by the Federal Aviation Administration (FAA) to ensure the continued safety and airworthiness of aircraft. When an AD is not complied with, it means that the aircraft is not meeting the required safety standards established for its operation, leading to significant safety risks. The status of unairworthiness can result in grounding the aircraft until compliance is achieved, as operating an unairworthy aircraft poses a danger to both the crew and the public. This is why ensuring compliance with ADs is critical for maintaining the aircraft’s airworthiness status and overall safety throughout its operational lifespan.
