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 2013–0188, dated August 19, 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: Airbus investigations on A300 aeroplanes revealed insufficient clearance between the Fuel Quantity Indicator (FQI) probes and adjacent structure or metallic components in the wing fuel tanks. A300–600 and A310 aeroplanes are also affected as they are identical in design. This condition, if not detected and corrected, could lead to electric arcing in a fuel tank in case of lightning strike, which could result in ignition and consequent fire or explosion in the fuel tank. To address this potential unsafe condition, Airbus issued Service Bulletin (SB) A300– 28–0080, SB A300–28–6065 and SB A310– 28–2145 and DGAC France issued AD 2000– 455–322 (https://ad.easa.europa.eu/ad/F2000-455-322) to cover A300 aeroplanes and AD 2002–170 (https://ad.easa.europa.eu/ad/ F-2002-170) to cover A300–600 and A310 aeroplanes (both EASA ADs were later revised) [Both EASA ADs correspond to FAA AD 2004–05–05, Amendment 39–13499 (69 FR 10319, dated March 5, 2004). Since those [EASA] ADs were issued, further analysis showed that they do not cover all potentially affected aeroplanes: A310 aeroplanes with optional Mod. no. 12248 embodied were excluded from the applicability of DGAC France AD 2002– 170(B) [https://ad.easa.europa.eu/ad/F-2002170], but are potentially affected, and therefore addressed through this [EASA] AD. For the reasons described above, this [EASA] AD (https://ad.easa.europa.eu/ad/ 2013-0188) requires a one-time [detailed visual] inspection of the affected aeroplanes for sufficient clearance between FQI probes [on both the left-hand (LH) side and righthand (RH) side of the trim horizontal stabilizer] and adjacent structure/metallic parts and, depending on findings, modification of the FQI probes. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating it in Docket No. FAA– 2014–0055. PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 Relevant Service Information Airbus has issued Service Bulletin A310–28–2145, Revision 01, dated March 4, 2003. 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. Costs of Compliance We estimate that this proposed AD affects 2 airplanes of U.S. registry. We also 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 $0 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $1,360, or $680 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. 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. E:\FR\FM\25FEP1.SGM 25FEP1 Federal Register / Vol. 79, No. 37 / Tuesday, February 25, 2014 / Proposed Rules 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.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A310-304, -322, -324, and -325 airplanes. This 
proposed AD was prompted by reports of insufficient clearance between 
the fuel quantity indicator (FQI) probes and the adjacent structure and 
metallic components in the wing fuel tanks. This proposed AD would 
require a one-time detailed visual inspection for sufficient clearance 
between FQI probes on both the left-hand side and right-hand side of 
the trim horizontal stabilizer and the adjacent structure and metallic 
components in the fuel tanks, and modification if necessary. We are 
proposing this AD to detect and correct insufficient clearance, which 
could lead to electrical arcing in a fuel tank during a lightning 
strike, which could result in ignition and consequent fire or explosion 
in the fuel tank.

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 2013-0188, dated August 19, 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:

    Airbus investigations on A300 aeroplanes revealed insufficient 
clearance between the Fuel Quantity Indicator (FQI) probes and 
adjacent structure or metallic components in the wing fuel tanks. 
A300-600 and A310 aeroplanes are also affected as they are identical 
in design.
    This condition, if not detected and corrected, could lead to 
electric arcing in a fuel tank in case of lightning strike, which 
could result in ignition and consequent fire or explosion in the 
fuel tank.
    To address this potential unsafe condition, Airbus issued 
Service Bulletin (SB) A300-28-0080, SB A300-28-6065 and SB A310-28-
2145 and DGAC France issued AD 2000-455-322 (https://ad.easa.europa.eu/ad/F-2000-455-322) to cover A300 aeroplanes and AD 
2002-170 (https://ad.easa.europa.eu/ad/F-2002-170) to cover A300-600 
and A310 aeroplanes (both EASA ADs were later revised) [Both EASA 
ADs correspond to FAA AD 2004-05-05, Amendment 39-13499 (69 FR 
10319, dated March 5, 2004).
    Since those [EASA] ADs were issued, further analysis showed that 
they do not cover all potentially affected aeroplanes: A310 
aeroplanes with optional Mod. no. 12248 embodied were excluded from 
the applicability of DGAC France AD 2002-170(B) [https://ad.easa.europa.eu/ad/F-2002-170], but are potentially affected, and 
therefore addressed through this [EASA] AD.
    For the reasons described above, this [EASA] AD (https://ad.easa.europa.eu/ad/2013-0188) requires a one-time [detailed 
visual] inspection of the affected aeroplanes for sufficient 
clearance between FQI probes [on both the left-hand (LH) side and 
right-hand (RH) side of the trim horizontal stabilizer] and adjacent 
structure/metallic parts and, depending on findings, modification of 
the FQI probes.

Relevant Service Information

    Airbus has issued Service Bulletin A310-28-2145, Revision 01, dated 
March 4, 2003. 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.

Costs of Compliance

    We estimate that this proposed AD affects 2 airplanes of U.S. 
registry.
    We also 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 $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $1,360, or $680 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD. 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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Airbus: Docket No. FAA-2014-0055; Directorate Identifier 2013-NM-
167-AD.

(a) Comments Due Date

    We must receive comments by April 11, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A310-304, -322, -324, and -325 
airplanes, certificated in any category, on which Airbus 
modification number 12248 has been embodied.

(d) Subject

    Air Transport Association (ATA) of America Code 28, Fuel.

(e) Reason

    This AD was prompted by reports of insufficient clearance 
between the fuel quantity indicator (FQI) probes and the adjacent 
structure and metallic components in the wing fuel tanks. We are 
issuing this AD to detect and correct insufficient clearance, which 
could lead to electrical arcing in a fuel tank during a lightning 
strike, which could result in ignition and consequent fire or 
explosion in the fuel tank.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspection and Modification

    Within 30 months after the effective date of this AD, do a one-
time detailed visual inspection for clearance between the FQI probes 
located in the trimmable horizontal stabilizer tank and the adjacent 
structure and metallic components, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A310-28-2145, 
Revision 01, dated March 4, 2003.
    (1) If the clearance of an FQI probe is found to be 3.0 
millimeters (mm) (0.118 inch) or more: No further action is required 
by paragraph (g) of this AD.
    (2) If the clearance of an FQI probe is found to be 2.5 mm (0.98 
inch) or more, and less than 3.0 mm (0.118 inch): Before further 
flight, loosen the probe screws and move the probe up and down to 
get the required minimum gap of 3.0 mm (0.118 inch), in accordance 
with the Accomplishment Instructions of Airbus Service Bulletin 
A310-28-2145, Revision 01, dated March 4, 2003.
    (3) If the clearance of an FQI probe is found to be less than 
2.5 mm (0.118 inch): Before further flight, modify each affected FQI 
probe by installing new FQI probe supports, in accordance with Step 
3.C., ``Repair,'' of the Accomplishment Instructions of Airbus 
Service Bulletin A310-28-2145, Revision 01, dated March 4, 2003.

(h) Credit for Previous Actions

    This paragraph provides credit for the actions required by 
paragraph (g) of this AD, if those actions were performed before the 
effective date of this AD using Airbus Service Bulletin A310-28-
2145, dated August 21, 2001.
