saver function could lead to inadequate oxygen supply to the flightcrew in case of decompression of the airplane or smoke or fire in the flight deck.
Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553b3B.
In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553d
for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forego notice and comment.

Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA
analysis is not required.

Authority for This Rulemaking
The Amendment
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.

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I
certify that this AD:
1 Is not a significant regulatory action under Executive Order 12866, and 2 Will not affect intrastate aviation in Alaska.

e Unsafe Condition This AD was prompted by report of defects on the piston hole associated with the O2

1 Where EASA AD 20210202R1 refers to its effective date, this AD requires using the effective date of this AD.
2 Paragraph 1 of EASA AD 2021
0202R1 specifies amending the applicable AFM airplane flight manual, but this AD
requires amending the applicable existing AFM and applicable corresponding operational procedures.
3 Whereas paragraph 1 of EASA AD
20210202R1 requires operators to inform all flight crews of the AFM amendments, and thereafter to operate the aeroplane accordingly, this AD does not specifically require those actions as they are already required by FAA regulations.

20210202R1.
