Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 97-20-07 for 
certain Airbus Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model A300 C4-605R Variant F airplanes (collectively 
called Model A300-600 series airplanes). AD 97-20-07 required 
repetitive inspections to detect fatigue cracking in the left and right 
wings in the area where the top skin attaches to the center spar, and 
repair or modification of this area if necessary. This new AD reduces 
the inspection compliance time and repetitive inspection intervals. 
This AD was prompted by a determination that the inspection compliance 
time and repetitive inspection interval must be reduced to allow timely 
detection of fatigue cracking in the left and right wings in the area 
where the top skin attaches to the center spar. We are issuing this AD 
to detect and correct this fatigue cracking, which could reduce the 
residual strength of the top skin of the wings, and consequently

[[Page 21247]]

affect the structural integrity of the airframe.

DATES: This AD becomes effective May 16, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 16, 
2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 97-20-07, Amendment 39-10145 (62 FR 50251, 
September 25, 1997) (``AD 97-20-07''). AD 97-20-07 applied to certain 
Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and 
Model A300 C4-605R Variant F airplanes (collectively called Model A300-
600 series airplanes). The NPRM published in the Federal Register on 
June 5, 2015 (80 FR 32058) (``the NPRM''). The NPRM was prompted by a 
determination that the inspection compliance time and repetitive 
inspection interval must be reduced to allow timely detection of 
fatigue cracking in the left and right wings in the area where the top 
skin attaches to the center spar. The NPRM proposed to continue to 
require repetitive inspections to detect fatigue cracking in the left 
and right wings in the area where the top skin attaches to the center 
spar, and repair or modification of this area if necessary. The NPRM 
also proposed to reduce the inspection compliance time and repetitive 
inspection intervals. We are issuing this AD to detect and correct this 
fatigue cracking, which could reduce the residual strength of the top 
skin of the wings, and consequently affect the structural integrity of 
the airframe.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0221, dated September 19, 2013 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-
605R Variant F airplanes (collectively called Model A300-600 series 
airplanes). The MCAI states:

    During fatigue tests conducted in the early 1990's, cracks were 
found on the top skin of the wing at the centre spar joint between 
ribs 1 and 7.
    Consequently, Airbus developed production mod. 10089 and issued 
Service Bulletin (SB) A300-57-6041, involving installation of a 
reinforcing plate on the affected area. Despite this improvement, 
subsequent cases of cracks were reported by operators.
    This condition, if not detected and corrected, could adversely 
affect the structural integrity of the aeroplane.
    To address this potential unsafe condition, Airbus issued SB 
A300-57-6044 and DGAC [Direction G[eacute]n[eacute]rale de 
l'Aviation Civile] France issued * * * [an airworthiness directive] 
(later revised twice) to require repetitive inspections of the 
affected area and, depending on findings, accomplishment of 
applicable corrective action(s).
    Since [the French] * * * [airworthiness directive] [which 
corresponds to FAA AD 97-20-07, Amendment 39-10145 (62 FR 50251, 
September 25, 1997)] was issued, a fleet survey and updated Fatigue 
and Damage Tolerance Analyses were performed in order to 
substantiate the second A300-600 Extended Service Goal (ESG2) 
exercise. The results of these analyses have shown that the 
inspection thresholds and intervals must be reduced to allow timely 
detection of these cracks and accomplishment of an applicable 
corrective action. Prompted by these findings, Airbus issued SB 
A300-57-6044 Revision 04 [dated August 19, 2011].
    For the reasons described above, this [EASA] AD retains the 
requirements of [the French AD] * * * which is superseded, but 
requires the repetitive inspections to be accomplished at reduced 
thresholds and intervals and, depending on findings, corrective 
actions.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
1426.

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.

Changes Made to This Final Rule

    Paragraph (m)(2) of the proposed AD inadvertently included the 
corrective action for the low frequency eddy current (LFEC) inspections 
for cracking specified in paragraphs (k) and (l) of the proposed AD; 
however, the corrective action in paragraph (m)(2) of this AD applies 
only to the new high frequency eddy current (HFEC) inspections required 
by this AD. We have revised paragraph (m)(2) of this AD to specify the 
corrective action for the HFEC inspections for cracking specified in 
paragraphs (i), (j), and (m)(1) of this AD. We have added new paragraph 
(m)(4) of this AD to specify the corrective actions for the LFEC 
inspections specified in paragraphs (k) and (l) of this AD.

Conclusion

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

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A300-57-6044, Revision 04, dated 
August 19, 2011, including Appendix 01, Revision 04, dated August 19, 
2011. The service information describes procedures for inspections to 
detect fatigue cracking in the left and right wings in the area where 
the top skin attaches to the center spar, and repair or modification of 
this area. This service information is reasonably available

[[Page 21248]]

because the interested parties have access to it through their normal 
course of business or by the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 47 airplanes of U.S. registry.
    The actions required by AD 97-20-07, and retained in this AD take 
about 3 work-hours per product, at an average labor rate of $85 per 
work-hour. Based on these figures, the estimated cost of the actions 
that were required by AD 97-20-07 is $255 per product.
    We also estimate that it will take about 5 work-hours per product 
to comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $19,975, or $425 per product
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this 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.

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.
