Federal Register Volume 80, Issue 108 (June 5, 2015)

We propose to supersede 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 requires 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. Since we issued AD 97-20-07, we have determined that the inspection compliance time and repetitive inspection interval must be reduced to allow timely detection of cracking in the left and right wings in the area where the top skin attaches to the center spar. This proposed AD would reduce the inspection compliance time and repetitive inspection intervals. We are proposing this AD to detect and correct this cracking, which could reduce the residual strength of the top skin of the wings, and consequently affect the structural integrity of the airframe.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede 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 requires 
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. Since we issued AD 
97-20-07, we have determined that the inspection compliance time and 
repetitive inspection interval must be reduced to allow timely 
detection of cracking in the left and right wings in the area where the 
top skin attaches to the center spar. This proposed AD would reduce the 
inspection compliance time and repetitive inspection intervals. We are 
proposing this AD to detect and correct this cracking, which could 
reduce the residual strength of the top skin of the wings, and 
consequently affect the structural integrity of the airframe.

Discussion

    On September 17, 1997, we issued AD 97-20-07, Amendment 39-10145 
(62 FR 50251, September 25, 1997). AD 97-20-07 requires actions 
intended to address an unsafe condition on the products listed above. 
Since we issued AD 97-20-07, we have determined that the inspection 
compliance time and repetitive inspection interval must be reduced to 
allow timely detection of cracking in the left and right wings in the 
area where the top skin attaches to the center spar.
    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 AD 95-086-180 (later revised twice) 
to require repetitive inspections of the affected area and, 
depending on findings, accomplishment of applicable corrective 
action(s).
    Since [DGAC] AD 1995-086-180(B)R2 [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 DGAC France AD 1995-086-180(B)R2, 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 it in Docket No. 
FAA-2015-1426.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A300-57-6044, Revision 04, 
including Appendix 01, 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. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI. 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 of this NPRM.

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.

Costs of Compliance

    We estimate that this proposed AD affects 47 airplanes of U.S. 
registry.
    The actions that are required by AD 97-20-07, Amendment 39-10145 
(62 FR 50251, September 25, 1997), and retained in this proposed 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 would take about 5 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed 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 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.

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:
