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 2012–0012, dated January 23, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: The flap interconnecting strut is a safety device of the High Lift System which acts as an alternative load path from one flap surface to another in case of a flap drive system disconnection. In such a failure case, the installed proximity provide information to the slat flap control computer (SFCC) and the operation of the flap drive system is inhibited. A recent engineering investigation has shown that, when a certain combination of target/sensor serial number (s/n) is installed on a flap interconnecting strut, a ‘‘target FAR’’ signal cannot be detected when reaching the mechanical end stop of the interconnecting strut. This condition, if not corrected, could cause a flap down drive disconnection to remain undetected, due to an already-failed interconnecting strut sensor, potentially resulting in asymmetric flap panel movement and consequent loss of control of the aeroplane. For the reason described above, this [EASA] AD requires the identification and replacement [or re-identifying] of struts that have a certain target/sensor s/n combination installed. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Service Bulletin A320–27–1206, Revision 01, dated October 10, 2011. 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 Although note 1 of the EASA Airworthiness Directive 2012–0012, dated January 23, 2012, allows flight for 50 flight cycles after the inspection of the flap down drive if an interconnecting strut cannot be replaced, this proposed AD does not include this exception. Costs of Compliance We estimate that this proposed AD affects 755 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: TKELLEY on DSK3SPTVN1PROD with PROPOSALS ESTIMATED COSTS Action Labor cost Inspection and Reidentification.

Federal Register / Vol. 78, No. 186 / Wednesday, September 25, 2013 / Proposed Rules We estimate the following costs to do any necessary replacements that would be required based on the results of the proposed inspection. We have no way of 58977 determining the number of aircraft that might need these replacements: ON-CONDITION COSTS Action Labor cost Parts cost Replacement ..................................... 10 work-hours × $85 per hour = $850 ......................................................... Authority for This Rulemaking List of Subjects in 14 CFR Part 39 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. Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. TKELLEY on DSK3SPTVN1PROD with PROPOSALS 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.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede airworthiness directive (AD) 2009–15– 17, which applied to certain Airbus Model A330–200 and –300; and Model A340–200 and –300 series airplanes. AD 2009–15–17 required an inspection for damage to the protective treatments or any corrosion of all main landing gear (MLG) bogie beams, and application of protective treatments if no damage or corrosion was found. If any damage or corrosion was found, corrective action followed by the application of protective treatments was required. Since we issued AD 2009–15–17, we received reports of thin paint coats and paint degradation on enhanced MLG bogie beams. This proposed AD would add repetitive detailed inspections of the MLG bogie beams. This proposed AD would also require modification of the MLG bogie beams, which would SUMMARY: PO 00000 Frm 00023 Fmt 4702 Sfmt 4702 terminate the repetitive inspections for any modified bogie beam. This proposed AD would also provide optional methods of compliance for inspections for corrosion, damage of the protective treatment, repair, and modification, of the MLG bogie beam. This proposed AD would also revise the applicability. We are proposing this AD to detect and correct damage or corrosion of the MLG bogie beams, which could cause a runway excursion event, bogie beam detachment from the airplane, or MLG collapse, which could result in damage to the airplane and injury to the occupants.

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, A319, A320, and A321 series airplanes. This proposed 
AD was prompted by a report that an investigation showed that when a 
certain combination of a target/proximity sensor serial number is 
installed on a flap interconnecting strut, a ``target FAR'' signal 
cannot be detected when it reaches the mechanical end stop of the 
interconnecting strut. This proposed AD would require an inspection to 
determine the part number (P/N) of the interconnecting struts installed 
on the wings, identifying the P/N and the serial number (S/N) of the 
associated target and proximity sensor if applicable, and replacing or 
re-identifying the flap interconnecting strut if applicable. We are 
proposing

[[Page 58976]]

this AD to detect and correct a latent failure of the flap down drive 
disconnection due to an already-failed interconnecting strut sensor,

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 2012-0012, dated January 23, 2012 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    The flap interconnecting strut is a safety device of the High 
Lift System which acts as an alternative load path from one flap 
surface to another in case of a flap drive system disconnection. In 
such a failure case, the installed proximity provide information to 
the slat flap control computer (SFCC) and the operation of the flap 
drive system is inhibited.
    A recent engineering investigation has shown that, when a 
certain combination of target/sensor serial number (s/n) is 
installed on a flap interconnecting strut, a ``target FAR'' signal 
cannot be detected when reaching the mechanical end stop of the 
interconnecting strut.
    This condition, if not corrected, could cause a flap down drive 
disconnection to remain undetected, due to an already-failed 
interconnecting strut sensor, potentially resulting in asymmetric 
flap panel movement and consequent loss of control of the aeroplane.
    For the reason described above, this [EASA] AD requires the 
identification and replacement [or re-identifying] of struts that 
have a certain target/sensor s/n combination installed.

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Service Bulletin A320-27-1206, Revision 01, dated 
October 10, 2011. 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

    Although note 1 of the EASA Airworthiness Directive 2012-0012, 
dated January 23, 2012, allows flight for 50 flight cycles after the 
inspection of the flap down drive if an interconnecting strut cannot be 
replaced, this proposed AD does not include this exception.

Costs of Compliance

    We estimate that this proposed AD affects 755 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of aircraft that might need 
these replacements:

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.

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 adding the following new AD:


Airbus: Docket No. FAA-2013-0791; Directorate Identifier 2012-NM-
026-AD.

(a) Comments Due Date

    We must receive comments by November 12, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Airbus Model A318-111, -112, -121, and -
122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, 
and -133 airplanes; Model A320-111, -211, -212, -214, -231, -232, 
and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -
213, -231, and -232 airplanes; certificated in any category; all 
manufacturer serial numbers.

 (d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
controls.

(e) Reason

    This AD was prompted by a report that an investigation showed 
that when a certain combination of a target/proximity sensor serial 
number is installed on a flap interconnecting strut, a ``target 
FAR'' signal cannot be detected when reaching the mechanical end 
stop of the interconnecting strut. We are issuing this AD to detect 
and correct a latent failure of the flap down drive disconnection 
due to an already-failed interconnecting strut sensor, which could 
result in asymmetric flap panel movement and consequent loss of 
control of the airplane.

(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) Inspection To Determine the Part Number of the Interconnecting 
Struts

    Within 8,000 flight hours after the effective date of this AD, 
inspect to determine the part number of the interconnecting struts 
installed on both the left-hand (LH) and right-hand (RH) wings of 
the airplane, in accordance with the Accomplishment Instructions of 
Airbus Service Bulletin A320-27-1206, Revision 01, dated October 10, 
2011. A review of the airplane maintenance records is acceptable for 
determining the part number of the installed interconnecting struts, 
in lieu of the inspection, if the part number of the installed 
interconnecting struts, and the part number and the serial number of 
the associated target and proximity sensor, can be conclusively 
determined from that review.
    (1) Airplanes on which Airbus modification 27956 has been 
embodied in production, on which no interconnecting strut having a 
part number specified in figure 1 to paragraph (g) of this AD, and 
has been replaced since the airplane's first flight: No further work 
is required by paragraph (g) of this AD.
    (2) If, during the inspection required by paragraph (g) of this 
AD, any interconnecting strut is installed with a part number 
specified in figure 1 to paragraph (g) of this AD: Within 8,000 
flight hours after the effective date of this AD, determine the part 
number and the serial number of the associated target and proximity 
sensor.
