Authority for This Rulemaking
List of Subjects in 14 CFR Part 39

Title 49 of the United States Code specifies the FAAs authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII:
Aviation Programs, describes in more detail the scope of the Agencys authority.
The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA
with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce.
This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Air Transport Association ATA of America Code 24, Electrical Power.
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.
f Compliance Comply with this AD within the compliance times specified, unless already done.
