PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 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 2007–0246, dated September 5, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: One A320 operator has reported a disbond on the composite rudder control rod. Investigations conducted by the supplier revealed that this disbond is due to an incorrect low volume of resin in the fibre composite. The supplier and AIRBUS have confirmed that some rudder control rods installed on A330 and A340–200/–300 aircraft before delivery or delivered as spare are also affected by this defect. Rudder control rod rupture can lead, in the worst case, in combination with a yaw damper runaway to an unsafe condition. In order to prevent such situation, this Airworthiness Directive (AD) requires a one time detailed visual inspection to identify the affected rods and to replace those affected by this issue. The unsafe condition is reduced control of the airplane. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Service Bulletins A330–27–3157 and A340–27–4156, both dated August 8, 2007. The actions described in this service information are 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. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But E:\FR\FM\10JAP1.SGM 10JAP1 Federal Register / Vol. 73, No. 7 / Thursday, January 10, 2008 / Proposed Rules we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. 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); 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 8 products of U.S. registry. We also estimate that it would take about 6 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Labor costs may be covered under warranty as described in the service information. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $3,840, or $480 per product. List of Subjects in 14 CFR Part 39 yshivers on PROD1PC62 with PROPOSALS 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: VerDate Aug<31>2005 14:28 Jan 09, 2008 Jkt 214001 Air transportation, Aircraft, Aviation safety, Safety. 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. § 39.13 [Amended] 2.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Boeing Model 777 airplanes. This proposed AD would require an inspection to determine the manufacturer and manufacture date of the oxygen masks in the center and outboard passenger service units (PSUs), crew rests, and lavatory and flight attendant oxygen boxes, as applicable. This proposed AD would also require related investigative/corrective actions if necessary. This proposed AD results from a report that several passenger masks with broken in-line flow indicators were found following a mask deployment. We are proposing this AD to prevent the in-line flow indicators of the passenger oxygen masks from fracturing and separating, which could inhibit oxygen flow to the masks and consequently result in exposure of the passengers and cabin attendants to hypoxia following a depressurization event.

Airworthiness Directives; Airbus Model A330-200, A330-300, A340-
200, and A340-300 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    One A320 operator has reported a disbond on the composite rudder 
control rod. Investigations conducted by the supplier revealed that 
this disbond is due to an incorrect low volume of resin in the fibre 
composite. The supplier and AIRBUS have confirmed that some rudder 
control rods installed on A330 and A340-200/-300 aircraft before 
delivery or delivered as spare are also affected by this defect. 
Rudder control rod rupture can lead, in the worst case, in 
combination with a yaw damper runaway to an unsafe condition.

* * * * *
    The unsafe condition is reduced control of the airplane. The 
proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

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 2007-0246, dated September 5, 2007 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    One A320 operator has reported a disbond on the composite rudder 
control rod. Investigations conducted by the supplier revealed that 
this disbond is due to an incorrect low volume of resin in the fibre 
composite. The supplier and AIRBUS have confirmed that some rudder 
control rods installed on A330 and A340-200/-300 aircraft before 
delivery or delivered as spare are also affected by this defect. 
Rudder control rod rupture can lead, in the worst case, in 
combination with a yaw damper runaway to an unsafe condition.
    In order to prevent such situation, this Airworthiness Directive 
(AD) requires a one time detailed visual inspection to identify the 
affected rods and to replace those affected by this issue.

    The unsafe condition is reduced control of the airplane. You may 
obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Service Bulletins A330-27-3157 and A340-27-4156, 
both dated August 8, 2007. The actions described in this service 
information are 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.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But

[[Page 1843]]

we might have found it necessary to use different words from those in 
the MCAI to ensure the AD is clear for U.S. operators and is 
enforceable. In making these changes, we do not intend to differ 
substantively from the information provided in the MCAI and related 
service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 8 products of U.S. registry. We also estimate that 
it would take about 6 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Labor costs may be covered under warranty as described in 
the service information. Based on these figures, we estimate the cost 
of the proposed AD on U.S. operators to be $3,840, or $480 per product.

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

Subject

    (d) Air Transport Association (ATA) of America Code 27: Flight 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    One A320 operator has reported a disbond on the composite rudder 
control rod. Investigations conducted by the supplier revealed that 
this disbond is due to an incorrect low volume of resin in the fibre 
composite. The supplier and AIRBUS have confirmed that some rudder 
control rods installed on A330 and A340-200/-300 aircraft before 
delivery or delivered as spare are also affected by this defect. 
Rudder control rod rupture can lead, in the worst case, in 
combination with a yaw damper runaway to an unsafe condition.
    In order to prevent such situation, this Airworthiness Directive 
(AD) requires a one time detailed visual inspection to identify the 
affected rods and to replace those affected by this issue.

    The unsafe condition is reduced control of the airplane.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) Within 600 flight hours after the effective date of this AD, 
identify the part number (P/N) and serial number (S/N) of all rudder 
control rods installed on the subject airplanes; in accordance with 
the Accomplishment Instructions of Airbus Service Bulletin A330-27-
3157 or A340-27-4156, both dated August 8, 2007, as applicable.
    (2) If the P/N and S/N of any rudder control rod identified in 
paragraph (f)(1) of this AD is not identified in Batch 1, Batch 2a,
