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 20200274, dated December 10, 2020 EASA AD 20200274.
h Exceptions to EASA AD 20200274
1 Where EASA AD 20200274 refers to its effective date, this AD requires using the effective date of this AD.
2 Where EASA AD 20200274 defines a reconnection cycle as repeated disconnection and connection of a battery . . . this AD defines it as one instance of disconnection and connection of a battery. . . .
3 The Remarks section of EASA AD
20200274 does not apply to this AD.
i No Reporting Requirement Although the service information referenced in EASA AD 20200274 specifies to submit certain information to the manufacturer, this AD does not include that requirement.

b Affected ADs None.

d Subject Air Transport Association ATA of America Code 24, Electrical Power.

e Reason This AD was prompted by a report that repetitive disconnection and reconnection of certain nickel-cadmium Ni-Cd batteries during airplane parking or storage could lead to a reduction in capacity of those batteries.
The FAA is issuing this AD to address reduced capacity of certain Ni-Cd batteries, which could lead to reduced battery endurance performance and possibly result in failure to supply the minimum essential electrical power during abnormal or emergency conditions.

j Other FAA AD Provisions The following provisions also apply to this AD:
1 Alternative Methods of Compliance AMOCs: The Manager, Large Aircraft Section, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the Large Aircraft Section, International Validation Branch, send it to the attention of the person identified in paragraph k2 of this AD.
Information may be emailed to: 9-AVS-AIR730-AMOC@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
2 Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, Large Aircraft Section, International Validation Branch, FAA; or EASA; or Airbus SASs EASA Design

paragraphs, including subparagraphs under an RC paragraph, must be done to comply with this AD; any paragraphs, including subparagraphs under those paragraphs, that are not identified as RC are recommended.
The instructions in paragraphs, including subparagraphs under those paragraphs, not identified as RC may be deviated from using accepted methods in accordance with the operators maintenance or inspection program without obtaining approval of an AMOC, provided the instructions identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to instructions identified as RC require approval of an AMOC.
