4. PHASE ONE: PREAPPLICATION, PLANNING, AND ASSESSMENT. The certificate holder develops plans for a proposed AMOC to the prescriptive rule(s). The plan should be based upon fatigue modeling data or some other form of data acceptable to the FAA that supports the proposed AMOC. The certificate holder will develop appropriate FRM and SA processes to identify and document risks and to apply appropriate mitigations to reduce the likelihood and severity of those risks. The certificate holder will utilize the FRM and SA processes in the development of flightcrew member FRMS operations procedures throughout the FRMS approval process, which will be driven by data and appropriate fatigue analysis methods.

a. Certificate Holder Responsibilities. The certificate holder will develop a data package to serve as a repository for all collected and analyzed data. Additionally, the certificate holder will maintain a collection of all amendments to their draft flightcrew member FRMS operations procedures to illustrate policy and procedural changes, driven by the results of the data analysis and the FRM and SA processes.

b. Objectives. This phase is designed as the platform from which the certificate holder will present their ideas, assessment, and plans for applying for a proposed FRMS authorization.

Phase 1 also serves as the initial meeting between the certificate holder and FAA to discuss the milestones and provide their proposed FRMS planning and assessment. The FAA will review the certificate holder’s proposed FRMS plans, identify the necessary guidance resource documents, and outline the phased authorization process for their proposed FRMS. The four gates in this phase are designed to give the certificate holder the necessary tools to develop the framework for their proposed FRMS. The objective of this phase is to prepare the certificate holder for data collection and ultimately to develop their proposed FRMS. The certificate holder should expect to accomplish modifications to some of their submissions required in Gates 1-4.

(1) Gate 1. The certificate holder will:

(a) Perform a needs analysis that defines the specific operational conditions for which a proposed FRMS will be applied to justify a deviation from prescriptive rules and why such an operation must or should be conducted under alternative duty and rest conditions.

(b) Define how proposed operational procedures will require an AMOC to the prescribed flight time, duty time, and rest requirements, citing the specific regulatory section and the applicable justification.

(c) Describe how proposed operational procedures will provide sufficient fatigue mitigations to provide an AMOC to that provided by current prescriptive rules.

(d) Perform a gap analysis to:

1. Identify elements of the proposed FRMS that are already available in existing systems and process.

2. Identify existing systems and process that could be modified to meet the needs of proposed FRMS (to minimize “reinventing the wheel”).

Appendix 2

3. Identify where new systems and processes need to be developed for the proposed FRMS.

(e) Prepare an FRMS policy statement signed by the accountable executive. Expect to revise the policy statement between phases and as the proposed FRMS becomes operational. The policy statement shall:

1. Reflect the shared responsibility of management, flight and cabin crews, and other involved personnel.

2. Clearly state the safety objectives of the proposed FRMS.

3. Be signed by the accountable executive of the organization.

4. Be communicated, with visible endorsement, to all the relevant areas and levels of the organization.

5. Declare management’s commitment to effective safety reporting.

6. Declare management’s commitment to the provision of adequate resources for the proposed FRMS.

7. Declare management’s commitment to continuous improvement of the proposed FRMS.

8. Require that clear lines of accountability for management, flight and cabin crews, and all other involved personnel are identified.

9. Require periodic reviews to ensure that it remains relevant and appropriate.

(f) Develop the FRMS documentation plan. The certificate holder shall develop and keep current FRMS documentation that describes and records:

1. FRMS policy and objectives.

2. FRMS processes and procedures.

3. Accountabilities, responsibilities and authorities for these processes and procedures.

4. Mechanisms for ongoing involvement of management, flight and cabin crewmembers, and all other involved personnel.

5. FRMS training programs, training requirements and attendance records.

6. Scheduled and actual flight times, duty periods and rest periods with significant deviations and reasons for deviations noted.

Appendix 2

7. F RM S outputs including findings from collected data, recommendations, and actions taken.

NOTE: E xp ect to revise this document between phases and as the FRMS becomes operational.

(g) Identify and allocate financial and human resources. The FRMS accountable executive needs to have the authority and control to ensure that this happens.

(h) Establish an FSAG, or its equivalent. Define the mission of the FSAG and outline the roles and responsibilities of each member, along with company resources. The stage at which the FSAG is established will vary according to the size and complexity of the organization and the FRMS and whether there are suitably qualified people in other parts of the organization who are available to begin these activities.

(i) Develop the FRMS communication plan. The current edition of ICAO Annex 6, Part I, Appendix 7 requires the certificate holder to have an FRMS communication plan that:

1. Explains FRMS policies, procedures, and responsibilities to all stakeholders.

2. Describes communication channels used to gather and disseminate FRMS-related information.

(j) There needs to be ongoing communication to stakeholders about the activities and safety performance of the FRMS and initiatives to ensure the commitment of all stakeholders.

Communications about the activities and safety performance of the FRMS (normally from the FSAG) need to be clear, timely, and credible. The information provided also needs to be tailored to the needs and roles of different stakeholder groups, with a minimum of unnecessary or irrelevant information. The certificate holder should choose from a variety of types of communication such as electronic media (websites, online forums, and email), newsletters, bulletins, seminars, periodic poster campaigns in strategic locations, and the like.

(k) Communications from crewmembers are vital for fatigue hazard identification in obtaining feedback on the effectiveness of controls and mitigations and in providing information for FRMS safety performance indicators. For these communications to be open and honest, all FRMS stakeholders need to have a clear understanding of the policies governing data confidentiality and the ethical use of information provided by crewmembers. Expect to revise this document between phases and as the FRMS becomes operational.

(2) Gate 2. The certificate holder will:

(a) Develop the FRMS implementation plan. The results of the gap analysis are used as the basis for the development of the certificate holder’s FRMS implementation plan.

Essentially, this provides a roadmap describing how the development of each of the FRMS processes will proceed. Expect to revise this document between phases and as the FRMS becomes operational.

Appendix 2

(b) Develop a fatigue reporting system. A fatigue report is a method for a flightcrew member to communicate to management personnel (and the FSAG) when they encounter a nonadverse fatigue event. There should be a clear process outlining how the fatigue report will be handled to include a Root Cause Analysis (RCA) and fatigue data collection and retention. The FRMS policy must provide for protection of privacy and methods to protect the employee from adverse actions that would discourage reporting events and conditions surrounding the events. The process should outline the length of time the data will be retained and a path to mitigation or management of the fatigue occurrence. Expect to revise this document between phases and as the FRMS becomes operational.

(c) Develop a fatigue incident reporting system. A fatigue incident is defined as an adverse event, in which fatigue is suspected to have been a causal or contributing factor, that results in an accident, incident, pilot deviation or noncompliance with FRMS policies or procedures. The fatigue incident reporting system is a method by which a flightcrew member communicates an adverse fatigue event to management personnel (and the FSAG). Reports of adverse events that may be attributable wholly or in part to fatigue are similar to crew reports, and can serve as a mechanism for obtaining all relevant information regarding fatigue contributions to the incident. FRMS policy would define how an adverse event is evaluated for potential fatigue involvement, as well as define a methodology for conducting a detailed RCA.

At a minimum, the incident investigation and reporting process must obtain all the necessary information to trace the root cause of the incident, especially the potential level of fatigue and the conditions that contributed to the fatigue-related event. The fatigue reporting policy must protect the privacy of employees and minimize adverse actions that would discourage reporting events and circumstances surrounding the events. Expect to revise this document between phases and as the FRMS becomes operational.

(d) Develop a system for monitoring flight crewmember fatigue as part of an overall FRMS. The data collected provides feedback to the certificate holder regarding conditions perceived to contribute to fatigue. To maximize the utility of such reports, procedures must be developed to capture all relevant information, such as the schedule leading up to the fatigue report, the actions of the employee to obtain rest, subjective and objective evidence of fatigue, environmental conditions that may have exaggerated or contributed to fatigue, relevant health or medical conditions, specific actions related to the incident, and communications prior to and during the event. Expect to revise this document between phases and as the FRMS becomes operational.

(e) Develop a FRM process and a SA process to identify fatigue risks and apply effective safety mitigations throughout the data collection process.

(f) Develop a training plan specific to the FRMS. The list below identifies general FRMS training subjects for the training plan. In addition to the general subjects, the certificate holder’s training plan should also include specific subjects relative to their proposed FRMS. Expect to revise this document between phases and as the FRMS becomes operational.

Figure 2-7, Fatigue Risk Management System Training Outline, outlines a sample FRMS training curriculum.
