DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2016–6671; Directorate Identifier 2015–NM–164–AD] Examining the AD Docket RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300B4–203 and A300B4–2C airplanes. This proposed AD was prompted by cracks found on pylon side panels (upper section) at rib 8. This proposed AD would require a detailed inspection for crack indications of the pylon side panels, a high frequency eddy current (HFEC) inspection to confirm any crack indications, modification of the pylon side panels, and repetitive inspections and repair if necessary. We are proposing this AD to detect and correct cracking of the pylon side panels. Such cracking could result in pylon structural failure and in-flight loss of an engine. DATES: We must receive comments on this proposed AD by July 7, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015–0201, dated October 7, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus Model A300B4–203 and A300B4–2C airplanes. The MCAI states: Cracks were found on pylon side panels (upper section) at rib 8 on Airbus A300, A310 and A300–600 aeroplanes equipped with General Electric engines. Investigation of these findings indicated that this problem was likely to also affect aeroplanes of this type design with other engine installations. This condition, if not detected and corrected, could lead to reduced strength of the pylon primary structure, possibly resulting in pylon structural failure and inflight loss of an engine. Prompted by these findings, EASA issued AD 2008–0181 [which corresponded to FAA AD 2010–06–04, Amendment 39–16228 (75 FR 11428, March 11, 2010; corrected May 4, 2010 (75 FR 23572))] to require repetitive detailed visual inspections and, depending on aeroplane configuration and/or findings, the accomplishment of applicable corrective action(s). Since that [EASA] AD 2008–0181 was issued, a fleet survey and updated Fatigue and Damage Tolerance analyses have been performed in order to substantiate the second A300–600 Extended Service Goal (ESG2) exercise. The results of these analyses have shown that the risk for these aeroplanes is higher than initially determined and consequently, the threshold and interval were reduced to allow timely detection of these cracks and the accomplishment of applicable corrective action(s). Consequently, EASA AD 2013–0136 was published to supersede EASA AD 2008–0181 and to require the inspections to be accomplished within reduced thresholds and intervals. Afterwards, [EASA] AD 2013–0136 was mistakenly revised [EASA AD 2013– 0136R1 corresponds to FAA AD 2015–26–06, Amendment 39–18354 (81 FR January 14,2016)] to reduce the Applicability, because it was considered at the time that aeroplanes on which Airbus mod 03599 was embodied, were not concerned by the requirements of EASA AD 2013–0136. Since EASA AD 2013–0136R1 was issued, a more thorough analysis determined that post-mod 03599 aeroplanes could be affected by this unsafe condition after all. [During] further deeper review, a list of nineteen A300 aeroplanes was identified as E:\FR\FM\23MYP1.SGM 23MYP1 32257 Federal Register / Vol. 81, No. 99 / Monday, May 23, 2016 / Proposed Rules missing in the [EASA] AD 2013–0136R1 applicability, (aeroplanes post-mod 03599). For the reasons described above this AD retains the requirements of EASA AD 2013– 0136R1 and mandates these requirements for the 19 missing A300 aeroplanes MSNs. 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–2016– 6671. Related Service Information Under 1 CFR Part 51 Airbus has issued Service Bulletin A300–54–0075, Revision 04, dated May 26, 2015. The service information describes procedures for an inspection for crack indications of the pylons, a HFEC inspection to confirm cracking, modification of the pylon side panels, and repairs if cracks are found. Airbus has also issued Service Bulletin A300–54–0081, dated August 11, 1993. This service information describes installation of a doubler on the left pylon 1 and right pylon 2, on pylon side panels (upper section) at Rib 8. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. 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. Differences Between Proposed Rule and Service Bulletin Unlike the procedures described in Airbus Service Bulletin A300–54–0075, Revision 04, dated May 26, 2015, this proposed AD would not permit further flight if cracks are detected in the pylon or pylon side panels. We have determined that because of the safety implications and consequences associated with that cracking, any cracked pylon or pylon side panel must be repaired or modified before further flight. This difference has been coordinated with EASA. Costs of Compliance We estimate that this proposed AD affects 4 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Cost per product Inspection of the pylon side panels. 30 work-hours × $85 per hour = $2,550 per inspection cycle. $2,550 per inspection cycle We estimate the following costs to do any necessary repairs that would be required based on the results of the proposed inspection. We have no way of Cost on U.S. operators $10,200 per inspection cycle. determining the number of airplanes that might need this repair. ON-CONDITION COSTS Action Labor cost Parts cost Cost per product Crack Repair ........................ 56 work-hours × $85 per hour = $4,760 per repair ...... $3,910 per repair ............... $8,670 per repair. sradovich on DSK3TPTVN1PROD with PROPOSALS Authority for This Rulemaking Regulatory Findings 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. 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.

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 
certain Airbus Model A300B4-203 and A300B4-2C airplanes. This proposed 
AD was prompted by cracks found on pylon side panels (upper section) at 
rib 8. This proposed AD would require a detailed inspection for crack 
indications of the pylon side panels, a high frequency eddy current 
(HFEC) inspection to confirm any crack indications, modification of the 
pylon side panels, and repetitive inspections and repair if necessary. 
We are proposing this AD to detect and correct cracking of the pylon 
side panels. Such cracking could result in pylon structural failure and 
in-flight loss of an engine.

DATES: We must receive comments on this proposed AD by July 7, 2016.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0201, dated October 7, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A300B4-203 and A300B4-2C airplanes. The MCAI states:

    Cracks were found on pylon side panels (upper section) at rib 8 
on Airbus A300, A310 and A300-600 aeroplanes equipped with General 
Electric engines. Investigation of these findings indicated that 
this problem was likely to also affect aeroplanes of this type 
design with other engine installations.
    This condition, if not detected and corrected, could lead to 
reduced strength of the pylon primary structure, possibly resulting 
in pylon structural failure and in-flight loss of an engine.
    Prompted by these findings, EASA issued AD 2008-0181 [which 
corresponded to FAA AD 2010-06-04, Amendment 39-16228 (75 FR 11428, 
March 11, 2010; corrected May 4, 2010 (75 FR 23572))] to require 
repetitive detailed visual inspections and, depending on aeroplane 
configuration and/or findings, the accomplishment of applicable 
corrective action(s).
    Since that [EASA] AD 2008-0181 was issued, a fleet survey and 
updated Fatigue and Damage Tolerance analyses have been performed in 
order to substantiate the second A300-600 Extended Service Goal 
(ESG2) exercise. The results of these analyses have shown that the 
risk for these aeroplanes is higher than initially determined and 
consequently, the threshold and interval were reduced to allow 
timely detection of these cracks and the accomplishment of 
applicable corrective action(s).
    Consequently, EASA AD 2013-0136 was published to supersede EASA 
AD 2008-0181 and to require the inspections to be accomplished 
within reduced thresholds and intervals. Afterwards, [EASA] AD 2013-
0136 was mistakenly revised [EASA AD 2013-0136R1 corresponds to FAA 
AD 2015-26-06, Amendment 39-18354 (81 FR January 14,2016)] to reduce 
the Applicability, because it was considered at the time that 
aeroplanes on which Airbus mod 03599 was embodied, were not 
concerned by the requirements of EASA AD 2013-0136.
    Since EASA AD 2013-0136R1 was issued, a more thorough analysis 
determined that post-mod 03599 aeroplanes could be affected by this 
unsafe condition after all.
    [During] further deeper review, a list of nineteen A300 
aeroplanes was identified as

[[Page 32257]]

missing in the [EASA] AD 2013-0136R1 applicability, (aeroplanes 
post-mod 03599).
    For the reasons described above this AD retains the requirements 
of EASA AD 2013-0136R1 and mandates these requirements for the 19 
missing A300 aeroplanes MSNs.

on the left pylon 1 and right pylon 2, on pylon side panels (upper 
section) at Rib 8.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

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.

Differences Between Proposed Rule and Service Bulletin

    Unlike the procedures described in Airbus Service Bulletin A300-54-
0075, Revision 04, dated May 26, 2015, this proposed AD would not 
permit further flight if cracks are detected in the pylon or pylon side 
panels. We have determined that because of the safety implications and 
consequences associated with that cracking, any cracked pylon or pylon 
side panel must be repaired or modified before further flight. This 
difference has been coordinated with EASA.

Costs of Compliance

    We estimate that this proposed AD affects 4 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
               Action                         Labor cost             Cost per product     Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Inspection of the pylon side panels  30 work-hours x $85 per      $2,550 per inspection   $10,200 per inspection
                                      hour = $2,550 per            cycle.                  cycle.
                                      inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs that 
would be required based on the results of the proposed inspection. We 
have no way of determining the number of airplanes that might need this 
repair.

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
               Action                         Labor cost                Parts cost           Cost per product
----------------------------------------------------------------------------------------------------------------
Crack Repair.......................  56 work-hours x $85 per      $3,910 per repair.....  $8,670 per repair.
                                      hour = $4,760 per repair.
----------------------------------------------------------------------------------------------------------------

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
