CHAPTER 5. VOLUNTARY DISCONTINUANCE BY CERTIFICATE HOLDER
5-1. VOLUNTARY DISCONTINUANCE. If a certificate holder elects to discontinue using electronic signatures, an electronic recordkeeping system, or an electronic manual system, it must inform the appropriate principal inspector (PI) or aviation safety inspector (ASI) by letter.
Once informed, the CHDO will amend the certificate holder’s Operations Specification (OpSpec) A025, Electronic Signatures, Electronic Recordkeeping Systems, and Electronic Manual Systems, to remove the authorization voluntarily discontinued. Certificate holders that voluntarily discontinue the use of electronic signatures, an electronic recordkeeping system, and/or an electronic manual system must include the following information in their discontinuance letter.
a. Discontinue Electronic Signatures.
(1) The letter from the certificate holder must include the projected date the certificate holder intends to discontinue using the electronic signatures.
(2) The letter must contain a description of how the certificate holder intends to transition from using electronic signatures to using pen-and-ink signatures.
(3) The letter must contain a description of how electronically signed documents and records will be reproduced and retained in accordance with the requirements of 14 CFR in hardcopy form.
(4) If an electronic signature is used in conjunction with electronic recordkeeping, then the electronic signature portion of the recordkeeping system must be removed.
b. Discontinue Electronic Recordkeeping System.
(1) The letter from the certificate holder must include the projected date the certificate holder intends to discontinue using the electronic recordkeeping system.
(2) The letter must contain a description of how the certificate holder intends to transition from electronic records to paper. The description must include how the certificate holder intends to ensure the content of the paper records exactly match the electronic content, including having the required signatures.
c. Discontinue Electronic Manual System.
(1) The letter from the certificate holder must include the projected date the certificate holder intends to discontinue using the system and provide hardcopy manuals, if required by appropriate 14 CFR parts.
(2) The letter must contain a description of how the certificate holder intends to transition from electronic manuals to paper manuals. The transition description should include procedures for the certificate holder to audit the paper manuals by comparing them to the electronic manuals and reconcile any differences.
