(d) Subject Air Transport Association (ATA) of America Code: 24, Electrical Power. (e) Unsafe Condition This AD was prompted by reports of temporary loss of all display units and the integrated electronic standby instrument (IESI).

(f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2023-0078R1, dated April 20, 2023 (EASA AD 2023-0078R1). (h) Exceptions to EASA AD 2023-0078R1 (1) Where EASA AD 2023-0078R1 refers to "05 May 2021 [the effective date of EASA AD 2021-0120-E]," this AD requires using May 14, 2021 (the effective date of AD 2021-10-20).

(3) Where paragraphs (1), (2), and (5) of EASA AD 2023-0078R1 specify to "inform all flight crews, and, thereafter, operate the aeroplane accordingly," this AD does not require those actions as those actions are already required by existing FAA operating regulations (see 14 CFR 91.9, 91.505, and 121.137).
