We propose to supersede Airworthiness Directive (AD) 2004-14- 09, for certain Airbus Model A320-211, -212, and -231 airplanes. AD 2004-14-09 currently requires repetitive inspections for fatigue cracking of the lower surface panel on the wing center box, and repair if necessary; and modification of the lower surface panel on the wing center box, which constitutes terminating action for the repetitive inspections. Since we issued AD 2004-14-09, we have determined that, based on the average flight duration, the average weight of fuel at landing is higher than that defined for the analysis of the fatigue- related tasks; and that shot peening might have been improperly done on the chromic acid anodizing (CAA) protection, which would adversely affect fatigue crack protection. This proposed AD would reduce the compliance times for the repetitive inspections, and would require a repair for certain airplanes. We are proposing this AD to detect and correct fatigue cracking of the lower surface panel on the wing center box, which could result in reduced structural integrity of the airplane.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2004-14-
09, for certain Airbus Model A320-211, -212, and -231 airplanes. AD 
2004-14-09 currently requires repetitive inspections for fatigue 
cracking of the lower surface panel on the wing center box, and repair 
if necessary; and modification of the lower surface panel on the wing 
center box, which constitutes terminating action for the repetitive 
inspections. Since we issued AD 2004-14-09, we have determined that, 
based on the average flight duration, the average weight of fuel at 
landing is higher than that defined for the analysis of the fatigue-
related tasks; and that shot peening might have been improperly done on 
the chromic acid anodizing (CAA) protection, which would adversely 
affect fatigue crack protection. This proposed AD would reduce the 
compliance times for the repetitive inspections, and would require a 
repair for certain airplanes. We are proposing this AD to detect and 
correct fatigue cracking of the lower surface panel on the wing center 
box, which could result in reduced structural integrity of the 
airplane.

Discussion

    On June 29, 2004, we issued AD 2004-14-09, Amendment 39-13718 (69 
FR 41398, July 9, 2004). AD 2004-14-09 requires actions intended to 
address an unsafe condition on the products listed above. AD 2004-14-09 
superseded AD 98-22-05, Amendment 39-10851 (63 FR 56542, October 22, 
1998).
    Since we issued AD 2004-14-09, Amendment 39-13718 (69 FR 41398, 
July 9, 2004), we have determined that, based on the average flight 
duration, the average weight of fuel at landing is higher than that 
defined for the analysis of the fatigue-related tasks; and that shot 
peening might have been improperly done on the CAA protection, which 
would adversely affect fatigue crack protection.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0065, dated March 14,

[[Page 26493]]

2014 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition on 
certain Model A320-211, -212, and -231 airplanes. The MCAI states:

    During center fuselage certification full scale test, damage was 
found in the center wing box (CWB) lower surface panel.
    This condition, if not detected and corrected, could affect the 
structural integrity of the CWB.
    To prevent such damage, Airbus developed mod 22418 which 
consists in shot-peening of the lower panel in the related area. Mod 
22418 has been embodied in production from aeroplane [manufacturer 
serial number] (MSN) 0359. For unmodified in-service aeroplanes, 
Airbus issued Service Bulletin (SB) A320-57-1082 to introduce 
repetitive High Frequency Eddy Current (HFEC) inspections on the 
external face of the center wing box lower panel between Frame (FR) 
41 and FR42 to detect damage.
    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France issued AD 2002-342 [http://ad.easa.europa.eu/blob/20023420tb_superseded.pdf/AD_F-2002-342_1] to require these 
inspections and, depending on findings, applicable corrective 
action(s). Airbus also issued SB A320-57-1043 as an optional 
terminating action for the repetitive inspections required by DGAC 
France AD 2002-342.
    Since that [DGAC] AD was issued, the results of a survey, 
carried out on the A320 fleet, highlighted some differences between 
the mission parameters, mainly on the weight of fuel at landing and 
on the average flight duration, which are higher than those defined 
for the analysis of the fatigue related tasks.
    These findings have led to an adjustment of the A320 reference 
fatigue mission. Consequently, the threshold and intervals of these 
repetitive inspections have been revised and a new threshold figure 
expressed in flight hours (FH) has been established.
    In addition, it has been identified that, on aeroplanes that 
have been modified in accordance with Airbus SB A320-57-1043 (Airbus 
mod 22418) at Revision 05 or an earlier Revision, the shot peening 
may have been improperly done on the Chromic Acid Anodizing (CAA) 
protection, which has no fatigue benefit effect. Therefore, the 
inspections per Airbus SB A320-57-1082 are required again on these 
aeroplanes.
    Consequently, new shot-peening procedures with proper CAA 
protection removal instructions have been developed and their 
embodiment through Airbus SB A320-57-1043 Revision 06 cancels the 
repetitive inspections per Airbus SB A320-57-1082, as required by 
DGAC France AD 2002-342.
    For the reasons described above, this new [EASA] AD retains the 
requirements of DGAC France AD 2002-342, which is superseded, but 
requires these actions to be accomplished within reduced thresholds 
and intervals. In addition, the optional terminating action 
provision (SB A320-57-1043) is amended by including reference to the 
SB at Revision 06.

The optional terminating action described in Airbus Service Bulletin 
A320-57-1043, Revision 06, dated December 5, 2013, is accomplishing 
shot peening in the radius of the milling step between stiffeners 13 
and 14 near the fuel pump aperture.
    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-
1275.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-57-1043, Revision 06, dated 
December 5, 2013. This service bulletin describes procedures for shot 
peening in the radius of the milling step between stiffeners 13 and 14 
near the fuel pump aperture.
    Airbus has also issued Service Bulletin A320-57-1082, Revision 04, 
dated December 5, 2013. This service bulletin describes procedures for 
inspections for cracking of the lower surface panel on the wing center 
box.
    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 46 airplanes of U.S. 
registry.
    The actions that are required by AD 2004-14-09, Amendment 39-13718 
(69 FR 41398, July 9, 2004), and retained in this proposed AD take 
about 25 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 2004-14-09 is $2,125 per product.
    The new requirements of this proposed AD would add no additional 
economic burden.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD. We have no way of determining the number of aircraft that might 
need these actions.

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.
