Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are superseding 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 required 
repetitive inspections in sections 13 through 18 of the fuselage 
between rivets of the longitudinal lap joints between frames (FRs) 18 
and 80 for cracking, and repair or modification if necessary. This new 
AD requires a revised repetitive inspection program of all longitudinal 
lap joints and repairs between FRs 18 and 80 to address widespread 
fatigue damage (WFD). This AD was prompted by an evaluation done by the 
design approval holder indicating that certain sections of the 
longitudinal lap joints are subject to WFD; therefore, a revised 
inspection program is necessary. We are issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective January 23, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 16, 
2011 (76 FR 63177, October 12, 2011).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2011-17-05, Amendment 39-16769 (76 FR 63177, 
October 12, 2011) (``AD 2011-17-05''). AD 2011-17-05 applied to certain 
Airbus Model A300 B2-1C, A300 B2-203, A300 B2K-3C, A300-B4-103, A300 
B4-203, and A300 B4-2C airplanes. The NPRM published in the Federal 
Register on July 7, 2016 (81 FR 44232). The NPRM was prompted by an 
evaluation done by the design approval holder indicating that certain 
sections of the longitudinal lap joints are subject to WFD. The NPRM 
proposed to continue to require repetitive inspections in sections 13 
through 18 of the fuselage between rivets of the longitudinal lap 
joints between FRs 18 and 80 for cracking, and repair or modification 
if necessary. The NPRM also proposed to require a revised repetitive 
inspection program of all longitudinal lap joints and repairs between 
FRs 18 and 80 to address this WFD. 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.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
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 
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 http://www.regulations.gov by searching for and locating it 
in Docket No. FAA-2016-7425.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
minor editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Costs of Compliance

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

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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 that this AD:
    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.
