AS/EN 9145 “APQP and PPAP”
Overview
The aerospace industry, known for its stringent quality demands and complex supply chains, requires meticulous attention to detail and unwavering commitment to safety and reliability. AS/EN 9145, a standard that integrates Advanced Product Quality Planning (APQP) and Production Part Approval Process (PPAP), is pivotal in meeting these high standards. Originally rooted in the automotive industry, the adaptation of these methodologies for aerospace reflects the sector’s push towards achieving unparalleled quality in every component and system. This blog explores the essence of AS/EN 9145, outlining its key requirements and the profound impact it has on the aerospace industry.
AS/EN 9145 standardises the approach to product quality planning and validation, ensuring that aerospace products meet all necessary performance, reliability, and safety standards before full-scale production and delivery. It encompasses two primary frameworks:
- Advanced Product Quality Planning (APQP): A structured process aimed at ensuring product quality and performance from the design phase to the product launch.
- Production Part Approval Process (PPAP): A standardised process that helps manufacturers and suppliers demonstrate that production processes have the capability to produce parts at required specifications consistently.
The key requirements can be categorised in two separate sections. Advanced Product Quality Planning (APQP) in AS/EN 9145 is a phased process that involves several critical steps:
- Plan and Define Program: Initiating the project with clear objectives, timelines, and understanding of customer needs.
- Product Design and Development Verification: Ensuring the design meets all requirements and is ready for production.
- Process Design and Development Validation: Establishing manufacturing processes that can consistently produce to specifications.
- Product and Process Validation: Conducting trials to validate the production process and the final product.
- Feedback, Assessment, and Corrective Action: Incorporating feedback mechanisms to improve the process continually.
Production Part Approval Process (PPAP) in AS/EN 9145 requirements in the aerospace context include:
- Documentation: Complete documentation of the design and manufacturing process, including change control and traceability.
- Samples: Submission of sample parts for approval, ensuring they meet design specifications.
- Validation: Detailed validation of the manufacturing process to demonstrate consistent quality and compliance with specifications.
AS/EN 9145 was published in November 2016 and applies internationally.
Does AS/EN 9145 affect my business?
Implementing AS/EN 9145 can significantly impact aerospace manufacturers and suppliers in several ways:
- Enhanced Product Reliability: By adhering to structured quality planning processes, companies can significantly reduce the risk of product failures and recalls.
- Compliance and Standardisation: Helps firms meet regulatory requirements and international standards, facilitating smoother market access and global operations.
- Cost Efficiency: Reducing variability in production and minimising defects leads to lower costs associated with rework and warranty claims.
AS/EN 9145 is more than just a set of guidelines; it is a comprehensive approach that integrates the entire aerospace product lifecycle, from concept through to delivery, under a uniform standard of quality. By embracing APQP and PPAP, aerospace businesses not only enhance their product quality and reliability but also fortify their market position through improved customer trust and satisfaction. For aerospace manufacturers and suppliers, understanding and implementing the principles of AS/EN 9145 is not just about compliance—it’s about building the foundation for excellence in an ever-evolving industry.
Do I need AS/EN 9145 in my ISO Compliance Register?
The standard affects a broad spectrum of entities within the aerospace industry:
- Original Equipment Manufacturers (OEMs): Major aerospace companies that design and assemble aircraft and other aerospace products.
- Tier 1 and Tier 2 Suppliers: Companies that provide essential components and sub-assemblies to OEMs or other suppliers up the chain.
- Material Suppliers: Providers of raw and specialty materials used in aerospace components must ensure their products meet the rigorous quality standards dictated by AS/EN 9145.
If this includes your business we strongly recommend you add AS/EN 9145 to your ISO Compliance Register.
