9.9 Auditor Training and Qualifications. If feasible, the aviation organization should specify that IEP auditors have training and/or experience in recognized quality management auditing, systems analysis, RCA, and risk assessment, as well as evaluation principles and techniques. Any one or combination of the following could accomplish training:

1. In-house prepared courses.

2. College courses.

3. Home study course materials.

4. Industry seminars and workshops.

5. Selected FAA courses.

9.10 Determination of Resources. To determine the resources needed by an IEP, senior management should make the scope of oversight and the extent of involvement for the IEP explicit. In most cases, the size of the organization and budgetary considerations will be the principal defining factors.

10 EXAMPLE IEP MANUAL. An example of an IEP manual that incorporates elements discussed within this AC is provided in Appendix B. An aviation organization’s IEP plan should be documented and may be a standalone manual or a portion of some larger department’s manual (e.g., the safety department’s manual). The example included in Appendix B may be more appropriate for a large part 121 air carrier. However, it can be scaled down and modified to fit other aviation organization’s needs.

Appendix A APPENDIX A. DEFINITIONS A.1 Audit. A methodical, planned review which builds on the principles of inspection.

An audit is used to determine how business is being conducted and compares results with how business should have been conducted in accordance with established procedures.

The most frequently used audit categories are (quality) system audits, service/product audits, and process audits.

A.2 Audit Scope. The operational disciplines and/or operational areas that are assessed during the conduct of an audit.

A.3 Auditor. An individual who has satisfied defined experience prerequisites and is successfully qualified under a defined training program to conduct audits.

A.4 Authority. As a safety attribute, a clearly identifiable, qualified, and knowledgeable person who has the authority to set up and change a process.

A.5 Concern. A conclusion by an auditor, supported by objective evidence, that is seen as a potential problem, trend, or inefficiency that may become a finding.

A.6 Continual. A close, prolonged succession or recurrence, infinite in time, without interruption.

A.7 Control. Key procedure, responsibility, or decision-making position within an organization, department, division, or functional area. Checks and restraints are designed into a process to ensure a desired result. Comprehensive evaluations (system audits) will focus on verifying and testing the controls within the organization.

A.8 Corrective Action. The action(s) taken to correct a deficiency with the intent to preclude recurrence of the finding or noncompliance of an approved standard.

A.9 Corrective Action Plan (CAP). The total plan of an aviation organization to close all findings through implementation of comprehensive corrective action. This plan should include the changes in policy and/or procedures that will ensure continued compliance.

A.10 Evaluation. A functionally independent review of company policies, procedures, and systems. If accomplished by the company itself, the evaluation should be done by an element of the company other than the one performing the function being evaluated.

The evaluation process builds on the concepts of audit and inspection. An evaluation is an anticipatory process, and is designed to identify and correct potential findings before they occur. An evaluation is synonymous with the term “systems audit.”

A.11 Evaluation Standard. Specific criteria on which basis a functional area will be evaluated in terms of compliance or conformance.

A.12 Evidence. A documented statement of fact, prepared by an aviation organization, which may be quantitative or qualitative, and is based on observations, inspections, measurements, or tests that can be verified. For the purpose of internal evaluation, A-1

Appendix A evidence should generally be written documentation that supports an IEP’s analysis and review. This data is necessary to substantiate findings or concerns and to enable management or evaluators to determine the root causes of any reported findings.

A.13 Finding. A determination as a result of an audit that compliance or conformance with an evaluation standard is not being achieved.

A.14 Followup. A process involving monitoring of CAPs to verify timely and effective implementation designed to eliminate the underlying (root) cause of the deficiency.

A.15 Inspection. The act of observing a particular event or action to ensure that correct procedures and requirements are followed during the accomplishment of that event or action. The primary purpose of an inspection is to verify that established standards are followed during an observed event or action.

Note: The term “inspection” is defined in this AC within the context of quality auditing principles. It does not address or define FAA inspections.

A.16 International Air Transport Association (IATA) Operational Safety Audit (IOSA).

An internationally recognized evaluation system designed to assess the operational management and control systems of a part 121 air carrier, which is based on ICAO standards.

A.17 Policy. A high-level overall plan embracing the general goals and acceptable practices of a group. Policies state how goals will be achieved.

A.18 Procedures. Written or unwritten methods (regulatory or nonregulatory) that an aviation organization uses to accomplish a particular process.

A.19 Process. A set of interrelated resources and activities that transform inputs to outputs.

Resources may include personnel, finance, facilities, equipment, techniques, and methods.

A.20 Process Audit. A documented activity that assesses the effectiveness and efficiency of a series of related or sequential work activities.

A.21 Quality Assurance (QA). The independent activity of providing the evidence needed to establish confidence, among all concerned, that the quality function is being performed effectively. This activity “assures quality” through independent evaluation of established processes, procedures, and documentation.

A.22 Quality Control. The determination of the quality of a product by inspection and testing to determine compliance with standards. This activity “controls quality” through establishment of effective controls, documentation, and procedures within specific functional areas.

A-2

Appendix A A.23 Quality Management System. A defined organizational structure, written management responsibilities, and associated system of processes, procedures, and detail documents to ensure compliance with internal standards or regulatory requirements.

A.24 Quality System Audit. A documented activity performed to verify by examination and evaluation of objective evidence that applicable elements of the quality management system are documented and effectively implemented in accordance with specific requirements.

A.25 Responsibility. As a safety attribute, a clearly identifiable, qualified, and knowledgeable person who is accountable for the quality of a process.

A.26 Root Cause Analysis (RCA). Determination of what caused a finding. The identification of the root cause is the key to the implementation of an effective corrective action.

Items to consider when determining the root cause should include deficiencies in training, materials, procedures, empowerment, or management oversight.

A.27 Senior Management. The highest level of management within an organization that has the authority and responsibility for setting policy, demonstrating commitment, meeting requirements, approving resources, setting objectives, implementing processes, and achieving desired outcomes.

A.28 Service/Product Audit. An objective and structured assessment of conformance to required service-level or product-level performance characteristics. It may be qualitative or quantitative, as appropriate.

A-3
