Federal Register Volume 80, Issue 201 (October 19, 2015)

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318; A319; A320; and A321 series airplanes. This proposed AD was prompted by reports of premature aging of certain passenger chemical oxygen generators that resulted in the generators failing to activate. This proposed AD would require an inspection to determine if certain passenger chemical oxygen generators are installed and replacement of affected passenger chemical oxygen generators. We are proposing this AD to prevent failure of the passenger chemical oxygen generator to activate and consequently not deliver oxygen during an emergency, possibly resulting in injury to the airplane occupants.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A318; A319; A320; and A321 series airplanes. This proposed 
AD was prompted by reports of premature aging of certain passenger 
chemical oxygen generators that resulted in the generators failing to 
activate. This proposed AD would require an inspection to determine if 
certain passenger chemical oxygen generators are installed and 
replacement of affected passenger chemical oxygen generators. We are 
proposing this AD to prevent failure of the passenger chemical oxygen 
generator to activate and consequently not deliver oxygen during an 
emergency, possibly resulting in injury to the airplane occupants.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2015-0117, dated June 24, 2015; corrected August 7, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A318; A319; A320; and A321 series airplanes. The MCAI states:

    Reports have been received indicating premature ageing of 
certain chemical oxygen generators, Part Number (P/N) 117042-XX (XX 
representing any numerical value), manufactured by B/E Aerospace. 
Some operators reported that when they tried to activate generators, 
some older units failed to activate. Given the number of failed 
units reported, all generators manufactured in 1999, 2000 and 2001 
were considered unreliable.
    This condition, if not corrected, could lead to failure of the 
generator to activate and consequently not deliver oxygen during an 
emergency, possibly resulting in injury to aeroplane occupants.
    To address this potential unsafe condition, Airbus issued Alert 
Operators Transmission (AOT) A35N006-14, making reference to B/E 
Aerospace Service Information Letter (SIL) D1019-01 (currently at 
Revision 1) and B/E Aerospace Service Bulletin (SB) 117042-35-001.
    Consequently, EASA issued AD * * * (later revised) to require 
identification and replacement of the affected oxygen generators.
    Since EASA AD 2014-0275R1 [http://ad.easa.europa.eu/ad/2014-0275R1] was issued, and following new investigation results, EASA 
have decided to introduce a life limitation concerning all P/N 
117042-XX chemical oxygen generators, manufactured by B/E Aerospace.
    For the reason described above, this [EASA] AD retains the 
requirements of the EASA AD 2014-0275R1, which is superseded, 
expands the scope of the [EASA] AD to include chemical oxygen 
generators manufactured after 2001, and requires their removal from 
service before exceeding 10 years since date of manufacture.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
3989.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Alert AOT A35N006-14, dated December 10, 2014, 
including Appendix 01.
    B/E Aerospace Inc. has issued Service Bulletin 117042-35-001, dated 
December 10, 2014.
    This service information describes procedures to replace certain 
passenger chemical oxygen generators. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section of this NPRM.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

[[Page 63138]]

Costs of Compliance

    We estimate that this proposed AD affects 953 airplanes of U.S. 
registry.
    We also estimate that it would take about 2 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $390 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $533,680, or $560 per product.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with, a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this proposed AD 
is 2120-0056. The paperwork cost associated with this proposed AD has 
been detailed in the Costs of Compliance section of this document and 
includes time for reviewing instructions, as well as completing and 
reviewing the collection of information. Therefore, all reporting 
associated with this proposed AD is mandatory. Comments concerning the 
accuracy of this burden and suggestions for reducing the burden should 
be directed to the FAA at 800 Independence Ave. SW., Washington, DC 
20591, ATTN: Information Collection Clearance Officer, AES-200.

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

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
