Airworthiness Directive Implementation Aviation Rulemaking Committee (AD ARC)
Based on widespread flight cancellations in March and April 2008 resulting from compliance issues found during an FAA oversight audit of airworthiness directives (ADs), the Independent Review Team (IRT) and Airworthiness Directive Compliance Review Team (AD CRT) were chartered to develop specific recommendations to improve the FAA’s safety culture and implementation of its safety systems, and airworthiness directive development and implementation processes. Both teams issued reports that discuss the respective team charters, activities, and final recommendations:
- IRT, Managing Risks in Civil Aviation (PDF)
A review of the FAA's approach to safety
- AD CRT, Airworthiness Directive 2006-15-15, Process Review Technical Report (PDF)
A review of the development, implementation, and compliance determinations associated with AD 2006-15-15
- AD CRT, Airworthiness Directives, Process Review Technical Report (PDF)
A review of the Title 14, Code of Federal Regulations, part 39 airworthiness directives process for commercial airplanes
AD ARC Activities and Products
In August 2009, the FAA chartered the Airworthiness Directive Implementation Aviation Rulemaking Committee (AD ARC) to evaluate and address the recommendations of the IRT and AD CRT relating to ADs. The AD ARC created working groups to support the review of the recommendations. These working groups developed working papers to document their review, analysis, and decisions.
The AD ARC deliverables and implementing actions are intended to improve:
- manufacturer (design approval holder) development of service instructions addressing airworthiness corrective actions,
- FAA AD development and oversight activities, and
- operator planning, accomplishment and maintenance of airworthiness corrective actions.
The AD ARC deliverables and implementing actions include:
- new or revised FAA guidance documents and orders,
- industry guidance documents, and
- FAA and industry training.
