Download as PDF 44232 Proposed Rules Federal Register Vol. 81, No. 130 Thursday, July 7, 2016 This section of the FEDERAL REGISTER contains notices to the public of the proposed issuance of rules and regulations. The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2016–7425; Directorate Identifier 2014–NM–244–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede Airworthiness Directive (AD) 2011–17– 05, for certain Airbus Model A300 B2– 1C, A300 B2–203, A300 B2K–3C, A300– B4–103, A300 B4–203, and A300 B4–2C airplanes. AD 2011–17–05 currently requires repetitive inspections in sections 13 through 18 of the fuselage between rivets of the longitudinal lap joints between frames (FR) 18 and 80 for cracking, and repair or modification if necessary. Since we issued AD 2011– 17–05, we have determined that a revised inspection program is necessary. This proposed AD would include a revised repetitive inspection program of all longitudinal lap joints and repairs between frames 18 and 80 to address this widespread fatigue damage (WFD). We are proposing this AD to detect and correct fatigue cracking of the longitudinal lap joints of the fuselage, which could result in reduced structural integrity of the airplane. DATES: We must receive comments on this proposed AD by August 22, 2016.

Discussion On September 23, 2011, we issued AD 2011–17–05, Amendment 39–16769 (76 FR 63177, October 12, 2011) (‘‘AD 2011–17–05’’). AD 2011–17–05 requires actions intended to address an unsafe condition on certain Airbus Model A300 B2–1C, A300 B2–203, A300 B2K–3C, A300–B4–103, A300 B4–203, and A300 B4–2C airplanes. Since we issued AD 2011–17–05, we have determined it is necessary to require a revised inspection program for the longitudinal lap joints and repairs between FR 18 and FR 80 because additional cracking was found in an expanded area. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014–0265, dated December 9, 2014 (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: Cracks were found on in-service aeroplanes in sections 13 to 18 of the fuselage between rivets of longitudinal lap joints between frames (FR) 18 and FR80. This condition, if not detected and corrected, could affect the structural integrity of the aeroplane. To address this unsafe condition, Airbus developed an inspection programme for the longitudinal lap joints and repairs between FR18 and FR80, and EASA issued AD 2007– 0091 [which corresponds to FAA AD 2011– 17–05] to require the implementation of that programme. Since EASA AD 2007–0091 was issued, [a] new Widespread Fatigue Damage regulation has been issued. This new regulation led to the revision of the maintenance programme for the longitudinal lap joints and repairs between FR18 and FR80. For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2007–0091, which is superseded, and requires implementation of the revised inspection programme. Required actions include repetitive inspections of the bonded inner E:\FR\FM\07JYP1.SGM 07JYP1 Federal Register / Vol. 81, No. 130 / Thursday, July 7, 2016 / Proposed Rules doublers of the longitudinal lap joints in sections 13 through 18 for disbonding or corrosion, and repairing any disbonding and corrosion; a follow-on rototest or ultrasonic inspection to verify cracking, and repair of any cracking. The repetitive inspection interval ranges from 3,000 flight cycles up to 8,000 flight cycles, depending on airplane configuration. 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–2016–7425. Widespread Fatigue Damage Fatigue damage can occur locally, in small areas or structural design details, or globally, in widespread areas. Multiple-site damage is widespread damage that occurs in a large structural element such as a single rivet line of a lap splice joining two large skin panels. Widespread damage can also occur in multiple elements such as adjacent frames or stringers. Multiple-site damage and multiple-element damage cracks are typically too small initially to be reliably detected with normal inspection methods. Without intervention, these cracks will grow, and eventually compromise the structural integrity of the airplane. This condition is known as widespread fatigue damage. It is associated with general degradation of large areas of structure with similar structural details and stress levels. As an airplane ages, WFD will likely occur, and will certainly occur if the airplane is operated long enough without any intervention. The FAA’s WFD final rule (75 FR 69746, November 15, 2010) became effective on January 14, 2011. The WFD rule requires certain actions to prevent structural failure due to WFD throughout the operational life of certain existing transport category airplanes and all of these airplanes that will be certificated in the future. For existing and future airplanes subject to the WFD rule, the rule requires that DAHs establish a limit of validity (LOV) of the engineering data that support the structural maintenance program. Operators affected by the WFD rule may not fly an airplane beyond its LOV, unless an extended LOV is approved. The WFD rule (75 FR 69746, November 15, 2010) does not require identifying and developing maintenance actions if the DAHs can show that such actions are not necessary to prevent WFD before the airplane reaches the LOV. Many LOVs, however, do depend on accomplishment of future maintenance actions. As stated in the WFD rule, any maintenance actions necessary to reach the LOV will be mandated by airworthiness directives through separate rulemaking actions. In the context of WFD, this action is necessary to enable DAHs to propose LOVs that allow operators the longest operational lives for their airplanes, and still ensure that WFD will not occur. This approach allows for an implementation strategy that provides flexibility to DAHs in determining the timing of service information development (with FAA approval), while providing operators with certainty regarding the LOV applicable to their airplanes. We are issuing this AD to detect and correct fatigue cracking of the longitudinal lap joints of the fuselage, which could result in reduced structural integrity of the airplane. 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 44233 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 Proposed AD and the MCAI or Service Information Unlike the procedures described in the service information, this proposed AD would not permit further flight if cracks are detected. We have determined that, because of the safety implications and consequences associated with that cracking, any cracked upper shell structure must be repaired before further flight. The MCAI refers to Airbus Service Bulletin A300–53–0211, Revision 08, dated November 26, 2013, for compliance times and for the new inspections. However, paragraph (l) of this proposed AD would require operators to do the initial inspections within 180 days after the effective date of this AD, in a method approved by the Manager, International Branch, ANM– 116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or Airbus’s EASA Design Organization Approval (DOA); and thereafter at intervals approved by the Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA; or EASA; or Airbus’s EASA DOA. We find that 180 days is an appropriate amount of time to accomplish the initial inspections and address the unsafe condition. These differences have been coordinated with the EASA and Airbus. Costs of Compliance We estimate that this proposed AD affects 4 airplanes of U.S. registry. ESTIMATED COSTS Cost per product Labor cost Retained actions from AD 2011–17–05 (5 airplanes) ..

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this proposed AD. 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 VerDate Sep<11>2014 13:03 Jul 06, 2016 Jkt 238001 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 PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 $317,475 11,900 Cost on U.S. operators $1,587,375 47,600 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\07JYP1.SGM 07JYP1 44234 Federal Register / Vol. 81, No. 130 / Thursday, July 7, 2016 / 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. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2011–17–05, Amendment 39–16769 (76 FR 63177, October 12, 2011), and adding the following new AD: ■ Airbus: Docket No. FAA–2016–7425; Directorate Identifier 2014–NM–244–AD.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2011-17-
05, for certain Airbus Model A300 B2-1C, A300 B2-203, A300 B2K-3C, 
A300-B4-103, A300 B4-203, and A300 B4-2C airplanes. AD 2011-17-05 
currently requires repetitive inspections in sections 13 through 18 of 
the fuselage between rivets of the longitudinal lap joints between 
frames (FR) 18 and 80 for cracking, and repair or modification if 
necessary. Since we issued AD 2011-17-05, we have determined that a 
revised inspection program is necessary. This proposed AD would include 
a revised repetitive inspection program of all longitudinal lap joints 
and repairs between frames 18 and 80 to address this widespread fatigue 
damage (WFD). We are proposing this AD to detect and correct fatigue 
cracking of the longitudinal lap joints of the fuselage, which could 
result in reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by August 22, 2016.

Discussion

    On September 23, 2011, we issued AD 2011-17-05, Amendment 39-16769 
(76 FR 63177, October 12, 2011) (``AD 2011-17-05''). AD 2011-17-05 
requires actions intended to address an unsafe condition on certain 
Airbus Model A300 B2-1C, A300 B2-203, A300 B2K-3C, A300-B4-103, A300 
B4-203, and A300 B4-2C airplanes.
    Since we issued AD 2011-17-05, we have determined it is necessary 
to require a revised inspection program for the longitudinal lap joints 
and repairs between FR 18 and FR 80 because additional cracking was 
found in an expanded area.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0265, dated December 9, 2014 (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:

    Cracks were found on in-service aeroplanes in sections 13 to 18 
of the fuselage between rivets of longitudinal lap joints between 
frames (FR) 18 and FR80.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.
    To address this unsafe condition, Airbus developed an inspection 
programme for the longitudinal lap joints and repairs between FR18 
and FR80, and EASA issued AD 2007-0091 [which corresponds to FAA AD 
2011-17-05] to require the implementation of that programme.
    Since EASA AD 2007-0091 was issued, [a] new Widespread Fatigue 
Damage regulation has been issued. This new regulation led to the 
revision of the maintenance programme for the longitudinal lap 
joints and repairs between FR18 and FR80.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2007-0091, which is superseded, and requires 
implementation of the revised inspection programme.

    Required actions include repetitive inspections of the bonded inner

[[Page 44233]]

doublers of the longitudinal lap joints in sections 13 through 18 for 
disbonding or corrosion, and repairing any disbonding and corrosion; a 
follow-on rototest or ultrasonic inspection to verify cracking, and 
repair of any cracking. The repetitive inspection interval ranges from 
3,000 flight cycles up to 8,000 flight cycles, depending on airplane 
configuration. 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-2016-7425.

Widespread Fatigue Damage

    Fatigue damage can occur locally, in small areas or structural 
design details, or globally, in widespread areas. Multiple-site damage 
is widespread damage that occurs in a large structural element such as 
a single rivet line of a lap splice joining two large skin panels. 
Widespread damage can also occur in multiple elements such as adjacent 
frames or stringers. Multiple-site damage and multiple-element damage 
cracks are typically too small initially to be reliably detected with 
normal inspection methods. Without intervention, these cracks will 
grow, and eventually compromise the structural integrity of the 
airplane. This condition is known as widespread fatigue damage. It is 
associated with general degradation of large areas of structure with 
similar structural details and stress levels. As an airplane ages, WFD 
will likely occur, and will certainly occur if the airplane is operated 
long enough without any intervention.
    The FAA's WFD final rule (75 FR 69746, November 15, 2010) became 
effective on January 14, 2011. The WFD rule requires certain actions to 
prevent structural failure due to WFD throughout the operational life 
of certain existing transport category airplanes and all of these 
airplanes that will be certificated in the future. For existing and 
future airplanes subject to the WFD rule, the rule requires that DAHs 
establish a limit of validity (LOV) of the engineering data that 
support the structural maintenance program. Operators affected by the 
WFD rule may not fly an airplane beyond its LOV, unless an extended LOV 
is approved.
    The WFD rule (75 FR 69746, November 15, 2010) does not require 
identifying and developing maintenance actions if the DAHs can show 
that such actions are not necessary to prevent WFD before the airplane 
reaches the LOV. Many LOVs, however, do depend on accomplishment of 
future maintenance actions. As stated in the WFD rule, any maintenance 
actions necessary to reach the LOV will be mandated by airworthiness 
directives through separate rulemaking actions.
    In the context of WFD, this action is necessary to enable DAHs to 
propose LOVs that allow operators the longest operational lives for 
their airplanes, and still ensure that WFD will not occur. This 
approach allows for an implementation strategy that provides 
flexibility to DAHs in determining the timing of service information 
development (with FAA approval), while providing operators with 
certainty regarding the LOV applicable to their airplanes.
    We are issuing this AD to detect and correct fatigue cracking of 
the longitudinal lap joints of the fuselage, which could result in 
reduced structural integrity of the airplane.

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 Proposed AD and the MCAI or Service 
Information

    Unlike the procedures described in the service information, this 
proposed AD would not permit further flight if cracks are detected. We 
have determined that, because of the safety implications and 
consequences associated with that cracking, any cracked upper shell 
structure must be repaired before further flight.
    The MCAI refers to Airbus Service Bulletin A300-53-0211, Revision 
08, dated November 26, 2013, for compliance times and for the new 
inspections. However, paragraph (l) of this proposed AD would require 
operators to do the initial inspections within 180 days after the 
effective date of this AD, in a method approved by the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA; or 
the European Aviation Safety Agency (EASA); or Airbus's EASA Design 
Organization Approval (DOA); and thereafter at intervals approved by 
the Manager, International Branch, ANM-116, Transport Airplane 
Directorate, FAA; or EASA; or Airbus's EASA DOA. We find that 180 days 
is an appropriate amount of time to accomplish the initial inspections 
and address the unsafe condition.
    These differences have been coordinated with the EASA and Airbus.

Costs of Compliance

    We estimate that this proposed AD affects 4 airplanes of U.S. 
registry.

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

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.

[[Page 44234]]

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.

days after November 16, 2011; whichever occurs later; do a detailed 
inspection of the fuselage bonded inner doubles of the longitudinal 
lap joints in Sections 16 and 17 at Stringer 31 left-hand and right-
hand for disbonding and cracking, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A300-53-229, 
Revision 5, dated April 8, 1997. If no disbonding and no corrosion 
are found, repeat the inspection thereafter at intervals not to 
exceed 7 years or 12,000 flight cycles, whichever occurs first.
    (1) If no cracking is found, and ``minor'' disbonding, as 
defined in Airbus Service Bulletin A300-53-229, Revision 5, dated 
April 8, 1997, is found: Repeat the inspection thereafter at 
intervals not to exceed 1 year for areas below stringer 22, and at 
intervals not to exceed 2 years for areas above and including 
stringer 22. Doing a repair, in accordance with Airbus Service 
Bulletin A300-53-229, Revision 5, dated April 8, 1997, terminates 
the repetitive inspections required by this paragraph for that area.
    (2) If no cracking is found, and ``major'' disbonding, as 
defined in Airbus Service Bulletin A300-53-229, Revision 5, dated 
April 8, 1997, is found: Within 1,000 flight cycles after doing the 
inspection, repair, in accordance with the Accomplishment 
Instructions of Airbus Service Bulletin A300-53-229, Revision 5, 
dated April 8, 1997.
    (3) If any cracking is found, repair prior to further flight, in 
accordance with Airbus Service Bulletin A300-53-229, Revision 5, 
dated April 8, 1997.

(l) New Repetitive Inspections and Repair

    Within 180 days after the effective date of this AD, do rototest 
and ultrasonic inspections, as applicable, for cracking of all 
longitudinal lap joints and repairs between frames 18 and 80; and 
repair any cracking before further flight; using a method approved 
by the Manager, International Branch, ANM-116, Transport Airplane 
Directorate, FAA; or the European Aviation Safety Agency (EASA); or 
Airbus's EASA Design Organization Approval (DOA). Repeat the 
applicable inspection, including post-repair inspections, thereafter 
at intervals approved by the Manager, International Branch, ANM-116, 
Transport Airplane Directorate, FAA; or EASA; or Airbus's EASA DOA. 
Accomplishing the initial inspection and applicable repairs required
