[Docket No. FAA-2012-0807; Directorate Identifier 2011-NM-191-AD]
RIN 2120-AA64

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A318-111 and -112 airplanes, and Model A319, A320, and 
A321 series airplanes. This proposed AD was prompted by reports of 
silicon particles inside the oxygen generator manifolds, which had 
chafed from the mask hoses during installation onto the generator 
outlets. This proposed AD would require identifying the part number and 
serial number of each passenger oxygen container, replacing the oxygen 
generator manifold of the affected oxygen container with a serviceable 
manifold, and performing an operational check of the manual mask 
release and corrective actions if necessary. We are proposing this AD 
to detect and correct non-serviceable oxygen generator manifolds, which 
could reduce or block the oxygen supply, which could result in injury 
to passengers when oxygen supply is needed.

DATES: We must receive comments on this proposed AD by October 1, 2012.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2011-0167, dated September 6, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

During production of passenger oxygen containers, the manufacturer 
B/E Aerospace detected some silicon particles inside the oxygen 
generator manifolds. Investigation revealed that those particles 
(chips) had chafed from the mask hoses during installation onto the 
generator outlets. It was discovered that a defective mask hose 
installation device had caused the chafing.

This condition, if not detected and corrected, could reduce or block 
the oxygen supply, possibly resulting in injury to passengers when 
oxygen supply is needed.

For the reasons described above, this [EASA] AD requires the 
identification and modification of the affected oxygen container 
assemblies. This AD also prohibits the installation of the affected 
containers on any aeroplane as replacement parts.

Required actions also include replacing the oxygen generator manifold 
of the affected oxygen container with a serviceable manifold, and doing 
an operational check of the manual mask release and corrective actions 
if necessary. You may obtain further information by examining the MCAI 
in the AD docket.

Relevant Service Information

    Airbus has issued Service Bulletin A320-35A1047, dated March 29, 
2011. B/E AEROSPACE has issued Service Bulletin 1XCXX-0100-35-005, 
Revision 1, dated December 15, 2012; and 22CXX-0100-35-003, Revision 1, 
dated December 20, 2011. The actions described in this service 
information are

[[Page 49387]]

intended to correct the unsafe condition identified in the MCAI.

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 the same 
type design.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 220 airplanes of U.S. registry. We also estimate 
that it would take about 3 work-hours per oxygen container to comply 
with the basic requirements of this proposed AD. The average number of 
oxygen containers per airplane is 50. The average labor rate is $85 per 
work-hour. Required parts would cost about $0 per product. Where the 
service information lists required parts costs that are covered under 
warranty, we have assumed that there will be no charge for these parts. 
As we do not control warranty coverage for affected parties, some 
parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $2,805,000, or $12,750 per airplane.

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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

    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]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Airbus: Docket No. FAA-2012-0807; Direc- torate Identifier 2011-NM-
191-AD.

(a) Comments Due Date

    We must receive comments by October 1, 2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A318-111 and -112 airplanes; 
A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; 
A320-111, -211, -212, -214, -231, -232, and -233 airplanes; A321-
111, -112, -131, -211, -212, -213, -231, and -232 airplanes; 
certificated in any category; all manufacturer serial numbers (MSN).

(d) Subject

    Air Transport Association (ATA) of America Code 35: Oxygen.

(e) Reason

    This AD was prompted by reports of silicon particles inside the 
oxygen generator manifolds, which had chafed from the mask hoses 
during installation onto the generator outlets. We are issuing this 
AD to detect and correct non-serviceable oxygen generator manifolds, 
which could reduce or block the oxygen supply, which could result in 
injury to passengers when oxygen supply is needed.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Part Number and Serial Number Identification

    Within 4,500 flight cycles, or 6,000 flight hours, or 20 months, 
whichever occurs first, after the effective date of this AD, 
identify the part number and serial number of each passenger oxygen 
container. A review of airplane maintenance records is acceptable in 
lieu of this identification if the part number and serial number of 
the oxygen container can be conclusively determined from that 
review.

(h) Replacement

    If the part number and serial number of the container are listed 
in table 2 and table 1 of this AD: Within the compliance time 
specified in paragraph (g) of this AD, replace the oxygen generator 
manifold of the affected oxygen container with a serviceable 
manifold and do an operational check of the manual mask release, in 
accordance with the Accomplishment Instructions of Airbus Service 
Bulletin A320-35A1047, dated March 29, 2011, except as provided by 
paragraphs (i)(1) through (i)(4) of this AD. If the operational 
check fails, before further flight, repair, using a method approved 
by either the Manager, International Branch, ANM 116, Transport 
Airplane Directorate, FAA; or the European Aviation Safety Agency 
(or its delegated agent).
