3-1 CHAPTER 3. IMPLEMENTATION: BUILDING A SAFETY MANAGEMENT SYSTEM (SMS)

3.1 Process Overview. There are several steps to developing and implementing an SMS that is compliant with part 5 (ref §§ 5.11, 5.13, 5.15):

• Required: Develop an organizational system description.

• Recommended: Complete a gap analysis to identify the areas where your organization complies with part 5 and where changes are required.

• Required: Develop and submit an SMS implementation plan to the FAA for approval.

• Required: Develop the necessary policies, processes, procedures, and systems to comply with part 5 and your implementation plan.

• Required: Implement the SMS in accordance with part 5 and your implementation plan.

3.1.1 Develop an Organizational System Description. Follow the guidance in paragraph

2.2.10 of this AC (ref § 5.17) to develop your organizational system description.

3.1.2 Gap Analysis. A gap analysis involves analyzing and assessing your existing programs, systems, processes, and activities with respect to SMS requirements found in part 5.

Most certificate holders have many of the elements of part 5 in their current processes, although those processes may not entirely fulfill the part 5 requirements. For example, the current processes may be limited in scope (i.e., do not cover the entire organization) and/or interoperability (i.e., do not interface sufficiently to form a “system”). If you determine that a process in your organization satisfies one or more part 5 requirements, your analysis should document how that process meets the requirements. You may document how you meet certain part 5 requirements by referencing the processes or procedures where the requirements are discussed. Your gap analysis should identify the additional policies, processes, and procedures you need to develop to fully comply with part 5.

3.1.3 Develop and Submit an Implementation Plan. Follow the guidance in paragraph 2.2.11 of this AC (ref § 5.19) to develop your implementation plan, and in paragraphs 2.2.7,

2.2.8, or 2.2.9 of this AC (ref §§ 5.11, 5.13, or 5.15) to submit your implementation plan for FAA approval.

3.1.4 Develop the Policies, Processes and Procedures to Comply with Part 5. Develop the necessary policies, processes, and procedures in accordance with the implementation plan (ref §§ 5.11, 5.13, or 5.15).

3.1.5 Implement the SMS. Follow the guidance in paragraphs 2.2.7, 2.2.8, or 2.2.9 of this AC (ref §§ 5.11, 5.13, or 5.15) to implement the SMS in accordance with your implementation plan.

1 APPENDIX A. GUIDANCE FOR DEVELOPING A SAFETY POLICY A.1 Safety Policy.

The safety policy must meet the requirements in § 5.21 and be signed by the accountable executive. References (i.e., “pointers” to other manuals which provide guidance how each requirement is to be met) could be embedded in the safety policy. It is important to remember the safety policy is unique to your organization and should be developed to meet the specific needs, activities, and structure of your organization. A safety policy is a document that states what your organization will do and how its employees are expected to act.

A.1.1 A sample safety policy is included in Paragraph A.2.

A.1.2 Reserved.

2 A.2 Sample Safety Policy.

Appendix B B-1 APPENDIX B. IDENTIFYING THE ACCOUNTABLE EXECUTIVE B.1 Identifying the Accountable Executive Flowcharts. The following flowcharts provide a series of questions to assist you with the selection of your organization’s accountable executive:
