SUPPLEMENTARY INFORMATION: On February 10, 2011, we issued AD 2011– 04–09, which applies to certain passenger-carrying transport category airplanes operating in 14 CFR part 121 PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 air carrier service; or U.S.-registered and operating under 14 CFR part 129, with a maximum passenger capacity of 20 or greater; and equipped with any chemical oxygen generator installed in any lavatory. Background This AD was prompted by reports that the current design of these oxygen generators presents a hazard that could jeopardize flight safety. We are issuing this AD to eliminate this hazard. FAA’s Determination and Requirements of This AD Since the unsafe condition described is likely to exist or develop on other airplanes of the same type design, we issued AD 2011–04–09 to eliminate a hazard with chemical oxygen generators in the lavatory, which, if not corrected, could jeopardize flight safety. The AD requires either activating all chemical oxygen generators in the lavatories until the generator oxygen supply is expended, or removing the oxygen generator(s); and, for each chemical oxygen generator, after the generator is expended (or removed), removing or restowing the oxygen masks and closing the mask dispenser door. We have determined that notice and opportunity for prior public comment on AD 2011–04–09 were contrary to the public interest, and good cause existed to make the AD effective immediately by individual notices issued on February 10, 2011, to the known U.S. owners and operators of certain passenger-carrying transport category airplanes operating in 14 CFR part 121 air carrier service; or U.S.-registered and operating under 14 CFR part 129, with a maximum passenger capacity of 20 or greater; and equipped with any chemical oxygen generator installed in any lavatory. These conditions still exist, and the AD is hereby published in the Federal Register as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13) to make it effective to all persons. Differences Between This Federal Register Version and the Individual Notices This Federal Register version of the AD is different from the individual notices previously issued. These individual notices contained a timelimited flight crew notification procedure. This procedure required that the pilot in command be notified that the oxygen generators in the lavatories had been rendered inoperative, and instructed the pilot in command to brief the crew that in the event of a rapid E:\FR\FM\08MRR1.SGM 08MRR1 Federal Register / Vol. 76, No. 45 / Tuesday, March 8, 2011 / Rules and Regulations decompression the lavatories needed to be checked. Since flight crews have been made aware of this AD by the actions in the individual notices, and these procedures were to be applied for a limited time (30 days) only, the procedures are considered no longer necessary, and are not included in this AD. Flight crews are still made aware of corrective actions taken as a result of this AD since maintenance activities are recorded and available to the flight crew using existing maintenance procedures. Related Rulemaking We are currently planning to issue a special Federal Aviation Regulation (SFAR) to address the regulatory compliance issues resulting from carrying out the actions required by this AD until the type certification and operational rules are modified. This AD is applicable to U.S.registered transport category airplanes operating under 14 CFR part 129 as identified in paragraph (c) of this AD. We will monitor actions taken by other airworthiness authorities to implement the requirements of this AD into their own fleets to determine if additional rulemaking actions are necessary. emcdonald on DSK2BSOYB1PROD with RULES Action by the State of Design This AD is applicable to all transport category airplanes identified in paragraph (c) of this AD. For the purposes of the FAA’s responsibility to notify other airworthiness authorities of continued airworthiness issues under International Civil Aviation Organization (ICAO) Annex 8, this AD is considered an action by the State of Design for United States products. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2011–0157; Directorate Identifier 2010– NM–261–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each VerDate Mar<15>2010 18:59 Mar 07, 2011 Jkt 223001 substantive verbal contact we receive about this AD. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s 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 Agency’s authority. We are 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. Regulatory Findings 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, (2) Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

VerDate Mar<15>2010 [FR Doc. 2011–5292 Filed 3–7–11; 8:45 am] The Rule This action amends Title 14 Code of Federal Regulations (14 CFR) part 73 by changing the R–2203 and R–2205 using agency of Special Use Airspace to, ‘‘U.S. Army, AK (USARAK), Commanding General, Fort Richardson, AK’’. This is an administrative change and does not affect the boundaries, or operating requirements of the airspace, therefore, notice and public procedures under 5 U.S.C. 533(b) is unnecessary. Section 73.22 of Title 14 CFR part 73 was republished in FAA Order 7400.8S, effective February 16, 2010. The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (1) Is not a ‘‘significant regulatory action’’ PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 under Executive Order 12866; (2) is not a ‘‘significant rule’’ under Department of Transportation (DOT) Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in subtitle VII, part A, subpart I, section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of the airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it amends Restricted Areas in Alaska. Environmental Review The FAA has determined that this action qualifies for categorical exclusion under the National Environmental Policy Act in accordance with 311d, FAA Order 1050.1E, ‘‘Environmental Impacts: Policies and Procedures.’’ This airspace action is not expected to cause any potentially significant environmental impacts, and no extraordinary circumstances exist that warrant preparation of an environmental assessment.

SUPPLEMENTARY INFORMATION: On February 10, 2011, we issued AD 2011-04-
09, which applies to certain passenger-carrying transport category 
airplanes operating in 14 CFR part 121 air carrier service; or U.S.-
registered and operating under 14 CFR part 129, with a maximum 
passenger capacity of 20 or greater; and equipped with any chemical 
oxygen generator installed in any lavatory.

Background

    This AD was prompted by reports that the current design of these 
oxygen generators presents a hazard that could jeopardize flight 
safety. We are issuing this AD to eliminate this hazard.

FAA's Determination and Requirements of This AD

    Since the unsafe condition described is likely to exist or develop 
on other airplanes of the same type design, we issued AD 2011-04-09 to 
eliminate a hazard with chemical oxygen generators in the lavatory, 
which, if not corrected, could jeopardize flight safety. The AD 
requires either activating all chemical oxygen generators in the 
lavatories until the generator oxygen supply is expended, or removing 
the oxygen generator(s); and, for each chemical oxygen generator, after 
the generator is expended (or removed), removing or re-stowing the 
oxygen masks and closing the mask dispenser door.
    We have determined that notice and opportunity for prior public 
comment on AD 2011-04-09 were contrary to the public interest, and good 
cause existed to make the AD effective immediately by individual 
notices issued on February 10, 2011, to the known U.S. owners and 
operators of certain passenger-carrying transport category airplanes 
operating in 14 CFR part 121 air carrier service; or U.S.-registered 
and operating under 14 CFR part 129, with a maximum passenger capacity 
of 20 or greater; and equipped with any chemical oxygen generator 
installed in any lavatory.
    These conditions still exist, and the AD is hereby published in the 
Federal Register as an amendment to section 39.13 of the Federal 
Aviation Regulations (14 CFR 39.13) to make it effective to all 
persons.

Differences Between This Federal Register Version and the Individual 
Notices

    This Federal Register version of the AD is different from the 
individual notices previously issued. These individual notices 
contained a time-limited flight crew notification procedure. This 
procedure required that the pilot in command be notified that the 
oxygen generators in the lavatories had been rendered inoperative, and 
instructed the pilot in command to brief the crew that in the event of 
a rapid

[[Page 12557]]

decompression the lavatories needed to be checked. Since flight crews 
have been made aware of this AD by the actions in the individual 
notices, and these procedures were to be applied for a limited time (30 
days) only, the procedures are considered no longer necessary, and are 
not included in this AD. Flight crews are still made aware of 
corrective actions taken as a result of this AD since maintenance 
activities are recorded and available to the flight crew using existing 
maintenance procedures.

Related Rulemaking

    We are currently planning to issue a special Federal Aviation 
Regulation (SFAR) to address the regulatory compliance issues resulting 
from carrying out the actions required by this AD until the type 
certification and operational rules are modified.
    This AD is applicable to U.S.-registered transport category 
airplanes operating under 14 CFR part 129 as identified in paragraph 
(c) of this AD. We will monitor actions taken by other airworthiness 
authorities to implement the requirements of this AD into their own 
fleets to determine if additional rulemaking actions are necessary.

Action by the State of Design

    This AD is applicable to all transport category airplanes 
identified in paragraph (c) of this AD. For the purposes of the FAA's 
responsibility to notify other airworthiness authorities of continued 
airworthiness issues under International Civil Aviation Organization 
(ICAO) Annex 8, this AD is considered an action by the State of Design 
for United States products.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2011-0157; Directorate Identifier 2010-NM-261-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's 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 Agency's authority.
    We are 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.

Regulatory Findings

    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,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979), and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    You can find our regulatory evaluation and the estimated costs of 
compliance in the AD Docket.

Adoption of the Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2011-04-09 Transport Category Airplanes: Amendment 39-16630. Docket 
No. FAA-2011-0157; Directorate Identifier 2010-NM-261-AD.

Effective Date

    (a) This AD becomes effective March 14, 2011, to all persons 
except those persons to whom it was made immediately effective by AD 
2011-04-09, issued on February 10, 2011, which contained the 
requirements of this amendment.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to transport category airplanes, in 
passenger-carrying operations, that are equipped with any chemical 
oxygen generator installed in any lavatory, and are:
    (1) Operating under 14 CFR part 121; or
    (2) U.S.-registered and operating under 14 CFR part 129, with a 
maximum passenger capacity of 20 or greater.

Subject

    (d) Joint Aircraft System Component (JASC)/Air Transport 
Association (ATA) of America Code 35, Oxygen.

Unsafe Condition

    (e) This AD was prompted by reports that the current design of 
chemical oxygen generators in the lavatories presents a hazard that 
could jeopardize flight safety. We are issuing this AD to eliminate 
this hazard.

Compliance

    (f) Comply with this AD within the compliance times specified, 
unless already done.

Oxygen Generator Deactivation

    (g) Within 21 days after the effective date of this AD, do the 
actions specified in paragraphs (g)(1) and (g)(2) of this AD.
    (1) Activate all chemical oxygen generators in the lavatories 
until the generator oxygen supply is expended. An operator may also 
remove the oxygen generator(s), in accordance with existing 
maintenance practice, in lieu of activating it.
    (2) For each chemical oxygen generator, after the generator is 
expended (or removed), remove or re-stow the oxygen masks and close 
the mask dispenser door.

    Note 1:  Chemical oxygen generators are considered a hazardous 
material and subject to specific requirements under Title 49 CFR for 
shipping. Oxygen generators must be expended prior to disposal but 
are considered a hazardous waste; therefore, disposal must be in 
accordance with all Federal, State, and local regulations. Expended 
oxygen generators are forbidden in air transportation as cargo. For 
more information, contact 1-800-HMR-4922.
