¶ … AS9100C has been updated and incorporates the requirements of the ISO 9001:2008. This was done to attend to stakeholder needs. These needs include improved customer satisfaction and to produce and continuously advance reliable, safe products to meet applicable statutory, regulatory, and customer requirements. The AS9100, now with the ISO 9001 system integration offers a quality management system that reduces or eliminates organization-unique requirements and offers a broader application of good practice.

The AS9103 is an operating standard that institutes modification management requirements for KCs. The AS9103 also provides a process to achieve the general requirements it specifies. Requirements for the standard also include a succinct assessment of the applicable maintenance/production process with the main objectives being to minimize and control modification in characteristics created by the process. It is a useful approach for a standard that is often used with the AS9100C.

a. Overview

AS9100 A replaced AS9000 in 1999, the former aerospace specific quality management system. AS9000 was replaced due to the review and improvement of the ISO 9000 family of standards. This meant that ISO 9001:2000 replaced ISO 9001:1994. AS9100 A was divided into two sections. These sections set out requirements established in the two 2000 and 1994 versions of ISO 9001.

b. Background

i. AS9100 and ISO 9001

The latest AS9100 revision C. has outmoded revision B. which replaced revision A. The only change is that in AS9100 revision C. The references to ISO 9001:2000 have been added. In regards to ISO 9001:2000, the primary modifications to AS9100 are based on the shift from a procedural to a process method. "AS9100 was developed by representatives from the Aerospace industry in Europe, Asia, USA and the Americas. Registration to AS9100 is encouraged for suppliers to organizations such as Boeing, Lockheed Martin, Northrop Grumman, Rolls Royce, GEAE, and NASA" (BSI Group, 2007, p1). In an article by Sorrentino, he discusses the need for update and modification of the AS9100:

As a prerequisite to guarantee compliance with AS9100C, aerospace engineers must understand why the AS9100 standard was modified with the revisions present in its current version, "C." Recent revisions to the ISO 9001 and AS9100C standards, as characterized in ISO 9001:2009 and AS9100C, expand and define the need to control Risk, Critical Items, and Key Characteristics. Also covered under these revisions is the need to possess a better understanding of Configuration and Risk Management (Sorrentino, 2011, p. 1).

The AS9103 was introduced to help define the aspect of a material or part whose fluctuation has a major influence on product fit, service life, performance, or manufacturability, key component for a part, sub-assembly or system: selected geometrical, material properties, cosmetic and functional which are quantitative and whose fluctuation is essential in meeting customer requirements. The key component for a process as it pertains to the AS9103 is selected perceptible parameters of a process whose control is crucial. Additionally when customer defined key component is not readily perceptible and other components may need to be controlled, formation of the AS9013 aids in modification.

AS9013 has primary intentions related to application of new parts and also application throughout the time of the program. This is to assure that changes are taken into attention. The AS9103 was established to help authorize requirements for management of key characteristics variation. It also helps specify general requirements by providing a process.

2. Body of Paper

a. Flow down of AS9103

The ones responsible for the flow down of AS9013 are producers and their subcontractors. The flow down of AS9013 is defined as the flow down of the requirements of the applicable revision of this standard to subcontractors. These subcontractors generate design characteristics. The flow down is also for assuring that KCs adhere to customer requirements.

i. Contractual and/or purchase order requirement

The contractual and/or purchase requirement often depends on the supplier collecting variables data on KPC's and/or candidate KPC's. The first step to the process is having the supplier validate measurement capability through Gage Repeatability & Reproducibility (Gage R & R) analysis. The requirement is simply a pass/fail result. Furthermore the supplier must submit KPC and/or candidate KPC information.

Hardware manufactured under this purchase order, must have its data collected. This also includes hardware that is not delivered. If for any reason the characteristics and/or related processes are found to have doubtful capability and/or stability, the company purchasing or issuing the contract reserves the right to require the supplier to provide root cause and take applicable disciplinary action in accordance with SAE AS9103, Appendix A, Sections 4 and 5 (except that maintenance of a Process Control Document is at the supplier's discretion) (Aerojet, 2013, p. 1).

ii. Build-to Print vs. Supplier Designed products

Build to print (BTP) and sometimes referred to as make to print (MTP), is a production method where only confirmed orders for products will allow products to be built or in this case printed. BTP is the oldest style of order printing and is the best method for low volume or highly customized products. Supplier designed products are products that are pre-made and have a set number in stock. Normally, mass produced items are supplier designed.

They commonly design, manufacture and service systems and components. Additionally, they provide integrated solutions for commercial, business, and military aircraft. They tend to supply international space programs. When it comes to which choice to make, if something needs to be highly customized or costs a lot to make, it would make sense to choose BTP (Johnson, 2011, p. 320). If it a common part and does not cost a lot to make, the choice would be supplier designed products. All in all it depends on need and purpose.

b. Importance of key characteristics (KCs)

Key characteristics are crucial in delivering variation control along with measuring and meeting customer requirements. It helps enhance customer satisfaction as well as identify customer-defined KC. KCs help communicate design output which may include identification of integral items that require particular actions to assure they are properly managed. In a report by SAE International Group (2008), they explain what are KCs and their value in the standard:

An attribute or feature whose variation has a significant influence on product fit, performance, service life, or producibility; that requires specific action for the purpose of controlling variation (reference 9100 and 9110).

This definition is further explained as follows:

• KCs for a part, subassembly, or system are those selected geometrical, material properties, functional, and/or cosmetic features; which are measurable, whose variation control is necessary in meeting customer requirements and enhancing customer satisfaction.

• Process KCs are those selected measurable characteristics of a process whose control is essential to manage variation of part or system KCs.

• Substitute KCs may be identified when a customer-defined KC is not readily measurable within the production/maintenance setting and other characteristics may need to be controlled to ensure conformance (SAE International Group, 2008, p. 6).

c. Application of AS9103

When considering the application of AS9013, it is important to understand its stages. First comes the review required performance, critical items, and key characteristics. Next comes the planning for a maintenance or manufacture process. Afterward, operate the process on a trial basis in order to create data. What follows is analysis of the data for action.

Then action can be taken from the studying of the process performance. Consequently, one must continue monitoring the ongoing process and finally, change or don't change process management. Understanding and knowing the stages of the standard allows for application across varying areas such as quality control and supplier chain. Many departments within a business or company can use this standard to evaluate its processes.

i. Statistical process control (SPC)

If Statistical Process Control (SPC) is elected as the main approach of control for the KC, the following requirements shall be met:

1. Control charts, Cpk, etc.

a. Process capability will be approved for KCs. The process capability index (e.g., Cp & Cpk) will be analyzed only when the process demonstrates stability and statistical control, utilizing suitable statistical methods and/or suitable control charts.

b. The process will be accomplished for example, with Cpk > 1.33, or as stated by the customer.

ii. Variation management

c. When comparable KCs from various products are linked on the same control chart such as: a part, process output control approach, or product family, the characteristics will share comparable variability and be attributable to the particular product or part.

d. When process capability is utilized to confirm decreased frequency of inspection, the process capability (probability of nonconformance) will be settled using known industry statistical designs.

1. Importance of lowering variation in manufacturing

In the economy of present day, many aspects of business and have been affected. Thanks to high oil prices and higher costs to transports products, it is important to reduce variation in manufacturing. Putting an emphasis on variation reduction, quality improvement, and cost savings, allows for business and companies to survive and specialize, offering customers a better product and service. The first quality revolution of the 1980s aided… [END OF PREVIEW]
