1          Upon request for assistance from Flight Standards personnel or Directorate/ACO/ECO regarding certification or airworthiness matters

1.1        Open AEG Record in accordance with office procedures, if applicable.

2          Assess request to determine nature of information required

2.1        Determine if information requested is within area of responsibilities; refer requestor to appropriate source if it is not

3          Identify and research matter/condition(s) that may require action

3.1        Compile relevant facts from a variety of sources:
- Aircraft Evaluation Group (AEG)
- Directorate
- Flight Standards District Office
- FAA Headquarters
- ACO
- Foreign Civil Aviation Authority
- Manufacturer/Vendors
- Aviation Associations

4          Determine if matter/condition(s) affects the certification, airworthiness or operation of the aircraft

4.1        Evaluate the following to determine if matter/condition significantly affects the airworthiness of the aircraft:
- Number of instances
- Nature of instances
- Possible effects on aircraft
4.2        Consult with the directorate/ACO/ECO Engineering to determine if the condition affects certification requirements of the aircraft
4.3        Consult with assigned AEG Operations Aviation Safety Inspector and ACO Flight Test Branch to determine if a condition affects the operation of the aircraft
4.4        Determine appropriate disposition of the condition
- If the condition affects the operation of the aircraft, request AEG operations to take appropriate action, respond to requester, then proceed to step 8 to close task, if applicable
- If the condition significantly affects the airworthiness of the aircraft, continue to step 5
- If the condition does not significantly affect the airworthiness of the aircraft, respond to requester, then proceed to step 8 to close task, if applicable

5          Select appropriate course of action

5.1        Analyze procedural, maintenance, or in-service data to determine the scope of the condition:
- If information is not sufficient, collect and analyze additional information
5.2        If condition affects safety:
- notify Directorate/ACO Engineering of potential need for Airworthiness Directive (AD) action
5.3        Determine the extent and source of condition:
- Is the condition related to only one type, model, and series of aircraft?
- Is the condition uniformly distributed to all type, model, and series of aircraft?
- Does the condition affect other operators?
5.4        Take appropriate action to correct the condition. Some examples:
- If the condition uniformly affects all operators, contact manufacturer and engineering specialists to investigate and resolve problem; request report of action taken
- If the condition does not uniformly affect all operators, contact the Flight Standards Regional Office or the operator’s Principal Inspector to investigate and resolve; request report of action taken
- If the condition is related to a manufacturing issue contact Manufacturing Inspection District Offices (MIDO) and/or ACO to investigate; request report of findings/action
- If the condition is related to an unsafe condition, contact the accountable Directorate/ACO/ECO Engineering staff to investigate the condition; request report of findings/action

6          Locate information needed and formulate response

6.1        Collect information from any of the following sources:
- Manufacturer/vendor manuals
- FAA regulations
- Manufacturer/vendor system schematics
- Personal or other expertise
6.2        Assemble information in usable form, e.g.:
- Bulletins
- Letters
- Memos
- Photocopies
- Videotapes
- Flowcharts

7          Provide requestor with information

8          Close AEG Record in accordance with office procedures, if applicable.
