What are Airworthiness Directives and who is responsible for their issuance?
The Federal Aviation Administration (FAA) is responsible for the promotion of aviation safety. One of ways they do this is through the airworthiness directives (AD) system. FAR 39 mandates the compliance with airworthiness directives.
The FAA issues AD's when an unsafe condition is found to exist in a product (aircraft, aircraft engine, propeller, or appliance.) These AD's notify aircraft owners and operators of potential unsafe conditions and require special inspections, repairs, or alterations to correct the unsafe condition.
The registered owner or operator of an aircraft is responsible for compliance with AD's applicable to the airframe, engine, propeller, appliances, parts and components for all aircraft it owns or operates.
Maintenance personnel are responsible for determining that all applicable airworthiness requirements are met when they accomplish an inspection in accordance with FAR 43.
