After inquiries and votes carried out in accordance with the rul
7、es of AECMA-STAN defined in AECMA-STANs General Process Manual, this standard has received approval for Publication. To continue to assure customer satisfaction, aerospace industry organizations must produce and continually improve safe, reliable products that meet or exceed customer and regulatory
8、requirements. The globalization of the aerospace industry and the resulting diversity of requirements and expectations have complicated this objective. This document is focussed on standardizing, to the extent possible, Operator self-verification practices in the aerospace industry. Establishing com
9、mon aerospace practices should result in improved quality and safety, decreased costs, and elimination or reduction of organization-unique requirements.

The practices recomm
12、ended in this document are intended to identify the basic elements and provide a “guideline” for structuring Operator Self-Verification programs within the aerospace industry; applicable to producers of commercial and military aircraft and weapons platforms, space vehicles, and all related hardware,
13、 software, electronics, engines and composite components. Operator Self-Verification programs are applied to improve the overall efficiency and product quality of processes considered mature, as judged by the implementing organization. Operator Self-Verification programs are not stand-alone processe
14、s, but augment existing quality management systems. The identified program elements are for voluntary implementation by the organization, and are not intended for contractual flow-down unless otherwise stipulated through contractual agreement. Purpose: To provide the recommended elements for Operato
15、r Self-Verification processes within the aerospace industry. 2 Normative references The following referenced documents are indispensable for the application of this document.

(i.e. “Approved Operators”, “Approved Technicians”, “Certified/Appr

29、erator, and augments existing, robust quality management systems to provide continued system and product quality improvement. Development and implementation of an effective Operator Self-Verification program affects the overall awareness and operating culture of the organization, and promotes reduct
30、ion in traditional inspections. Integration of Operator Self-Verification into the work process, establishes process and operator performance metrics, and through regular surveillance reviews, allows the operators to control and improve the quality of the products. Operator Self-Verification program
31、s can be implemented on a selective or organizational wide basis and can reduce the cost of quality, improve defect prevention and detection, improve efficiency and productivity, eliminate waste, and require operator accountability. Operator Self-Verification enriches employees through promoting act
32、ive involvement in the manufacture and improvement of products. It also promotes streamlining of product and process flows by eliminating the need to move the product to a traditional inspector, or an inspector to the product, enhances the potential for product improvement through in depth review by
33、 various disciplines, and thus potentially provides improved quality and greater customer satisfaction. Operator Self-Verification programs should highlight the responsibility/accountability for product quality, promote employee pride of ownership, recognize superior performance, and provide operato
34、rs with enhanced ability to control process performance. 5 Basic required elements In addition to an existing quality management system, the following items are deemed essential in implementing and maintaining an Operator Self Verification program: Documention of Operator Self-Verification candidate
35、 processes; Development of plans for Operator Self-Verification program implementation; Documented training and competency of Self-Verification operators; Evaluation of human performance limitations; Development of metrics for oversight of process and operator performance; Documented implementation
36、and maintenance plans for Self-Verification processes. Page 6 prEN 9162:20056 Application 6.1 General The basic elements of Operator Self-Verification are essential in establishing a robust program in compliance with this practice. However, the details of these elements are left to the discretion of
37、 the implementing organization based on evaluation of their needs. Effective and continued communication with the customer and/or regulatory authority representatives, as well as with company personnel that will be affected by the program, is essential and vital in deploying self-verification progra
38、ms. Effective, two-way communication builds the necessary broad base of employee understanding, participation, involvement and commitment; promotes customer acceptance and satisfaction with the program and its results; and avoids unnecessary remedial activities, change costs and delays in implementi
39、ng the program. Effective program implementation also requires the development of a broad based plan with provisions to inform all personnel involved of the programs objectives and intent, formalize actions required, ensure management commitment, and establish the timetable for goal completion. In a
40、ddition to the plan, the organization should establish and formally document the process for operator self verification program implementation and operation. The documentation should provide program philosophy and operational perspective to company and customer personnel. Subordinate documentation c
41、an be developed and deployed, as deemed necessary, to provide specific or detailed direction and instructions for the work force, management, administrative personnel, program/process records and record retention, etc. 6.2 Identification of processes eligible for using Operator Self-Verification Whe
42、n identifying potential processes for Operator Self-Verification, either selectively or on an organizational wide basis, the implementing organization should consider and select processes based on: acceptable levels of perceived risk associated with the candidate process and the reduction or elimina
43、tion of traditional inspection (formal or informal processes for risk analysis may be used); demonstrated stability and maturity of the process through such methods as first article performance results and process generated non-conformities within the established process performance review period/cy
44、cle time. Operator Self-Verification should not include those processes considered by the organization, customer, or regulatory authorities as “critical processes” (those that mandate traditional inspection for review and acceptance), unless adequate mitigation of risk is agreed to and in place, and
45、 proper delegation has been specified. The selection process is most effective when performed by multi-disciplined groups. The combined efforts of the various disciplines such as Manufacturing, Quality Assurance, Manufacturing Engineering, Engineering and others offers a more diverse overview of can
46、didate processes. 6.3 Development of plans for Operator Self-Verification implementation, maintenance and continuous improvement In developing the plans for implementation of Operator Self-Verification, the organization should consider the various logistical needs of program implementation, such as
47、training and retraining requirements, oversight documentation and control system requirements, management review and performance metrics, methods for data integration and feedback to allow for effective operator control and improvement of process performance. At a minimum consider: Requirements for
48、comprehensive training programs; Establishing operational baselines to assist in determining improvement resulting from Operator Self-Verification program implementation; Possible changes to documentation for transferring of inspection activities; Appropriate methods for operators to determine proce
49、ss compliance to requirements and to regulate the process to maintain that compliance; Page 7 prEN 9162:2005 Independent surveillance of Self-Verification operators, products and processes; A review of all contributing elements to ensure provision of defect free sources and environment for the Self-Verification Operator; Documented alternative courses of action for self verification operators and processes found to be operating outside quality metric criteria (examples: suspension of qualification, retraining, requalification or restart actions).
