ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede Airworthiness Directive (AD) 2012–13– 06, for all Airbus Model A300 series airplanes and all Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes). AD 2012– 13–06 currently requires a one-time detailed inspection to determine the length of the fire shut-off valve (FSOV) bonding leads and for contact or chafing of the wires, and corrective actions if necessary. Since we issued AD 2012– 13–06, a determination was made that the description of the inspection area specified in the service information was misleading; therefore, some operators might have inspected incorrect bonding leads. This proposed AD would instead require a new one-time detailed inspection of the FSOV bonding leads to ensure that the correct bonding leads are inspected, and corrective action if necessary. We are proposing this AD to detect and correct contact or chafing of wires and the bonding leads, which, if not detected, could be a source of sparks in the wing trailing edge, and could lead to an uncontrolled engine fire.

Discussion On June 21, 2012, we issued AD 2012–13–06, Amendment 39–17108 (77 FR 40485, July 10, 2012). AD 2012–13– 06 requires actions intended to address an unsafe condition on all Airbus Model A300 series airplanes and all Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model A300 C4– 605R Variant F airplanes (collectively called Model A300–600 series airplanes). Since we issued AD 2012–13–06, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2013–0204, dated September 6, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During a scheduled maintenance check, one operator reported inoperative Fire Shut Off Valve (FSOV). Investigations showed damage at wire located between engine 2 hydraulic FSOV and wing rear spar, in the zones 575/675, and at bonding lead, located between wing rib 7A and rib 8 below hydraulic pressure lines. Similar inspections on different aeroplanes have shown that one of the causes of damage is the contact between bonding lead and the harness, due to over length of the bonding lead. This condition, if not detected and corrected, could lead to either: —a potential explosive condition onground if the FSOV, that is installed in fuel vapor zone is commanded to close position, or —a temporary uncontrolled engine fire, if combined with a fire event in the nacelle fed by an hydraulic leakage and not controlled by the fire extinguishing system. As the affected wire is not powered during normal operation, no defect can be detected unless a test is performed on the FSOV during maintenance check. EASA issued AD 2011–0084 [https://ad. easa.europa.eu/blob/easa_ad_2011_ 0084.pdf/AD_2011–0084_Superseded] which required a one-time [detailed] inspection of the wires [for contact or chafing] located between [LH/RH] engines hydraulic FSOV and wing rear spar in the zones 575/675, and the bonding lead [for length] that is located between rib 7A and rib 8 below hydraulic pressure lines, and corrective actions [repair of wires or replacement of bonding leads] depending on findings. It appeared that the original issue of the Airbus inspection Service Bulletins (SB’s) as E:\FR\FM\31MRP1.SGM 31MRP1 17004 Federal Register / Vol. 80, No. 61 / Tuesday, March 31, 2015 / Proposed Rules well as EASA AD 2011–0084 might have caused possible misunderstandings on the exact bonding leads and wires that are required to be inspected. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2011–0084, which is superseded, and requires additional work on aeroplanes that have already been inspected in accordance with the instructions of the original issue of the SB’s. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2015– 0679. Related Service Information Under 1 CFR Part 51 Airbus has issued Service Bulletin A300–24–0106, Revision 01, including Appendices 01, 02, 03, and 04, dated March 26, 2013 (for Model A300 series airplanes); and Service Bulletin A300– 24–6108, Revision 01, including Appendices 01, 02, 03, and 04, dated March 26, 2013 (for Model A300–600 series airplanes. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. This service information is reasonably available; see ADDRESSES for ways to access this service information. asabaliauskas on DSK5VPTVN1PROD with PROPOSALS 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. Costs of Compliance We estimate that this proposed AD affects 123 airplanes of U.S. registry. We estimate that it would take about 8 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 $500 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $145,140, or $1,180 per product. In addition, we estimate that any necessary follow-on actions would take about 1 work-hour and require parts costing $50, for a cost of $135 per product. We have no way of VerDate Sep<11>2014 18:18 Mar 30, 2015 Jkt 235001 determining the number of products that may need these actions. 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, 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.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2012-13-
06, for all Airbus Model A300 series airplanes and all Model A300 B4-
600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R 
Variant F airplanes (collectively called Model A300-600 series 
airplanes). AD 2012-13-06 currently requires a one-time detailed 
inspection to determine the length of the fire shut-off valve (FSOV) 
bonding leads and for contact or chafing of the wires, and corrective 
actions if necessary. Since we issued AD 2012-13-06, a determination 
was made that the description of the inspection area specified in the 
service information was misleading; therefore, some operators might 
have inspected incorrect bonding leads. This proposed AD would instead 
require a new one-time detailed inspection of the FSOV bonding leads to 
ensure that the correct bonding leads are inspected, and corrective 
action if necessary. We are proposing this AD to detect and correct 
contact or chafing of wires and the bonding leads, which, if not 
detected, could be a source of sparks in the wing trailing edge, and 
could lead to an uncontrolled engine fire. May 5, 2015.

Discussion

    On June 21, 2012, we issued AD 2012-13-06, Amendment 39-17108 (77 
FR 40485, July 10, 2012). AD 2012-13-06 requires actions intended to 
address an unsafe condition on all Airbus Model A300 series airplanes 
and all Model A300 B4-600, B4-600R, and F4-600R series airplanes, and 
Model A300 C4-605R Variant F airplanes (collectively called Model A300-
600 series airplanes).
    Since we issued AD 2012-13-06, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Union, has issued EASA Airworthiness Directive 2013-0204, 
dated September 6, 2013 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for the specified products. The MCAI states:

    During a scheduled maintenance check, one operator reported 
inoperative Fire Shut Off Valve (FSOV). Investigations showed damage 
at wire located between engine 2 hydraulic FSOV and wing rear spar, 
in the zones 575/675, and at bonding lead, located between wing rib 
7A and rib 8 below hydraulic pressure lines.
    Similar inspections on different aeroplanes have shown that one 
of the causes of damage is the contact between bonding lead and the 
harness, due to over length of the bonding lead.
    This condition, if not detected and corrected, could lead to 
either:
    --a potential explosive condition on-ground if the FSOV, that is 
installed in fuel vapor zone is commanded to close position, or
    --a temporary uncontrolled engine fire, if combined with a fire 
event in the nacelle fed by an hydraulic leakage and not controlled 
by the fire extinguishing system.
    As the affected wire is not powered during normal operation, no 
defect can be detected unless a test is performed on the FSOV during 
maintenance check.
    EASA issued AD 2011-0084 [https://ad.easa.europa.eu/blob/easa_ad_2011_0084.pdf/AD_2011-0084_Superseded] which required a one-
time [detailed] inspection of the wires [for contact or chafing] 
located between [LH/RH] engines hydraulic FSOV and wing rear spar in 
the zones 575/675, and the bonding lead [for length] that is located 
between rib 7A and rib 8 below hydraulic pressure lines, and 
corrective actions [repair of wires or replacement of bonding leads] 
depending on findings.
    It appeared that the original issue of the Airbus inspection 
Service Bulletins (SB's) as

[[Page 17004]]

well as EASA AD 2011-0084 might have caused possible 
misunderstandings on the exact bonding leads and wires that are 
required to be inspected.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2011-0084, which is superseded, and requires 
additional work on aeroplanes that have already been inspected in 
accordance with the instructions of the original issue of the SB's.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A300-24-0106, Revision 01, 
including Appendices 01, 02, 03, and 04, dated March 26, 2013 (for 
Model A300 series airplanes); and Service Bulletin A300-24-6108, 
Revision 01, including Appendices 01, 02, 03, and 04, dated March 26, 
2013 (for Model A300-600 series airplanes. The actions described in 
this service information are intended to correct the unsafe condition 
identified in the MCAI. This service information is reasonably 
available; see ADDRESSES for ways to access this service information.

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.

Costs of Compliance

    We estimate that this proposed AD affects 123 airplanes of U.S. 
registry.
    We estimate that it would take about 8 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 $500 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $145,140, or $1,180 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 1 work-hour and require parts costing $50, for a cost of 
$135 per product. We have no way of determining the number of products 
that may need these actions.

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, 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

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 removing Airworthiness Directive (AD) 
2012-13-06, Amendment 39-17108 (77 FR 40485, July 10, 2012), and adding 
the following new AD:

Airbus: Docket No. FAA-2015-0679; Directorate Identifier 2013-NM-
182-AD.
