Ref: 8110.37D Section 2-5. DER Designations.
a. Structural DERs may prepare and/or approve, within the limits of their appointment, the following items that comply with pertinent regulation(s):

c. Authorization. A DER must obtain authorization from the managing ACO before he initiates data approvals for major repairs or major alterations. The ACO’s authorization may be verbal and confirmed in writing or by an authorization letter. See a sample authorization letter in appendix 3, figure 6. A DER to whom we grant this special authorization may approve technical data for major repairs and major alterations without first notifying the project ACO, except when the part is critical or life limited, or if the work will be done outside the country. For guidance
concerning operating outside the United States, see Order 8100.8. For critical or life limited parts, the DER must contact the project ACO for guidance.
(1) Aircraft Repairs and Alterations. Authorization for major repairs or major
alterations applicable to aircraft, and engines and propellers installed on aircraft, are limited to
the approval of a specific repair or alteration to specific serial number aircraft. A DER must
coordinate with his managing ACO for authorization to approve data for multiple use repairs
without specific aircraft serial number effectivity.
(2) Component Repairs and Alterations. A DER authorized to work on major
repairs or major alterations of parts, components, engines, or propellers not installed on aircraft is limited to approving data for a specific repair or alteration to specific serial number parts, components, engines, or propellers, or to a specific work order for parts or components that are not serialized. A DER must coordinate with his managing ACO for authorization to approve data for multiple use repairs, repair schemes, or
establishment of repair limits for multiple use repairs to components.
