STANDARD
AS13004™
Issued 2017-08
Process Failure Mode and Effects Analysis (PFMEA) and Control Plans
RATIONALE
This standard was created to establish a common practice for effective process risk identification, assessment, mitigation,
and prevention. It defines a methodology to mitigate risk using Process Flow Diagrams (PFDs), Process Failure Mode and
Effects Analysis (PFMEA), and Control Plans. It is to be used by organizations throughout the life cycle of a product.
FOREWORD
To assure customer satisfaction, the aviation, space, and defense industry organizations have to produce and continually
improve safe, reliable products that equal or exceed customer and regulatory authority requirements. The globalization of
the industry and the resulting diversity of regional/national requirements and expectations have complicated this objective.
End-product organizations face the challenge of assuring the quality of and integration of product purchased from
suppliers throughout the world and at all levels within the supply chain. Industry suppliers face the challenge of delivering
product to multiple customers having varying quality expectations and requirements.
The Aerospace Engine Supplier Quality (AESQ) Committee was established as the G-22 Technical Committee under the
SAE Aerospace Council to develop, specify, maintain, and promote quality standards relating to the aerospace engine
supply chain. The principles defined within this standard may be applicable to other segments of the aviation, space, and
defense industries.
The AESQ strategy is to create a series of related quality standards for use within the aerospace engine supply chain with
the intention of exceeding customer expectations through effective application of the full series of interrelated AESQ
quality standards (see Appendix A).
