B-9

Appendix B B.2.8 Top Management Review. The Safety Division and the IERB will report all audit findings on an annual basis to senior management.

B.2.9 Senior Management. The CEO and President constitute as senior management.

When making the report to senior management, the Safety Division and the IERB will include all audit information and findings in the report. Senior management will be actively involved in the review process to ensure audit program effectiveness and provide oversight and guidance to operating departments. The senior management’s involvement includes review of all audits and corrective actions through periodic meetings, briefings, or written reports to assess the effectiveness of each operating department’s CAP and audit program.

B.2.10 Schedule. Flight operations, M&E, customer service, and IFS will receive a focused quarterly evaluation (e.g., first quarter records, second quarter manuals, etc.). The schedule for the evaluations of these areas will be determined during the first quarter of each calendar-year, and will be entered into the system by IEP personnel. All stations within the airline’s system will be evaluated three times per year on the following basis:

1. “A” Stations (those with more than 1 million passenger enplanements per year) will be evaluated three times per year by IEP personnel.

2. “B” Stations (those with more than 250,000 but fewer than 1 million passenger enplanements per year) will be evaluated twice per year by IEP personnel, and once per year on a self-audit basis. The self-audit will be forwarded to the IEP department for entry into the database and followup activity tracking.

3. “C” Stations (those with fewer than 250,000 passenger enplanements per year) will be evaluated once per year by IEP personnel, and twice per year on a self-audit basis. The self-audits will be forwarded to the IEP department for entry into the database and followup activity tracking.

4. A list of stations denoting their status (e.g., A, B, or C) will be maintained by the IEP department and will be updated based on actual passenger enplanement records from the previous calendar-year.

5. The schedule for the evaluations and self-audits will be entered into the system and tracked by Internal Evaluation personnel. The IEP department will maintain evaluation and self-audit checklists.

6. Other evaluation and audit activity will be carried out by IEP personnel on an event-driven basis or by request from senior management.

B.2.11 CAPs. All CAPs will be tracked to completion in the system. Audits will remain in an “open” status until all corrective actions have been completed.

B.2.12 RCA. The airline has selected the XYZ system for use by the IEP team to perform RCA and to aid in the development of corrective actions for deep-rooted problems that are discovered during the course of inspections, audits, and evaluations. All IEP personnel will receive training in the use of this system.
