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. \n\nBackground \n\n\n\tThis 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. \n\nFAA's Determination and Requirements of This AD \n\n\n\tSince 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. \n\tWe 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. \n\tThese 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. \n\nDifferences Between This Federal Register Version and the Individual Notices \n\n\n\tThis 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 \n\n((Page 12557)) \n\ndecompression 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 flightcrew using existing maintenance procedures. \n\nRelated Rulemaking \n\n\n\tWe 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. \n\tThis 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. \n\nAction by the State of Design \n\n\n\tThis 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. \n\nComments Invited \n\n\n\tThis 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. \n\tWe will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about thisAD. \n\nAuthority for This Rulemaking \n\n\n\tTitle 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. \n\tWe 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. \n\nRegulatory Findings \n\n\n\tThis AD will not have federalism implications under Executive Order 13132. This AD will not havea 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. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866, \n\t(2) Is not a ''significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), and \n\t(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. \n\tYou can find our regulatory evaluation and the estimated costs of compliance in the AD Docket. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. \n\nAdoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 asfollows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):
