Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 2000-12-
12, for certain Airbus Model A300, A300-600, and A310 series airplanes. 
AD 2000-12-12 currently requires inspecting to detect cracks in the 
lower spar axis of the nacelle pylon between ribs 9 and 10, and repair 
if necessary. AD 2000-12-12 also provides for optional modification of 
the pylon, which terminates the inspections for Model A300 series 
airplanes. Since we issued AD 2000-12-12, we have received reports of 
cracking of the lower pylon spar after accomplishing the existing 
modification and have determined that shorter initial and repetitive 
inspection compliance times are necessary to address the identified 
unsafe condition. This proposed AD would reduce the initial and 
repetitive inspection compliance times. We are proposing this AD to 
detect and correct fatigue cracking, which could result in reduced 
structural integrity of the lower spar of the nacelle pylon.

DATES: We must receive comments on this proposed AD by February 13, 
2014.

Discussion

    On June 9, 2000, we issued AD 2000-12-12, Amendment 39-11790 (65 FR 
39072, June 23, 2000). That AD required actions intended to address an 
unsafe condition on the products listed above. AD 2000-12-12 superseded 
AD 95-10-03, Amendment 39-9220 (60 FR 25604, May 12, 1995).
    Since we issued AD 2000-12-12, Amendment 39-11790 (65 FR 39072, 
June 23, 2000), The European Aviation Safety Agency (EASA), which is 
the Technical Agent for the Member States of the European Community, 
has issued EASA Airworthiness Directive 2013-0016, dated September 17, 
2013 (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 between ribs 9 and 10 in the lower pylon spar 
of A310 aeroplanes equipped with Pratt & Whitney (PW) engines.
    For A310, A300 and A300-600 aeroplanes and, in order to prevent 
crack initiation, the implementation of a first inspection programme 
of this area was required by DGAC [Direction G[eacute]n[eacute]rale 
de l'Aviation Civile] France AD 1992-049-130(B) [which corresponds 
to certain actions in FAA AD 2000-12-12, Amendment 39-11790 (65 FR 
39072, June 23, 2000)], currently at Revision 4.
    General Electric (GE) and PW pylons on A300 aeroplanes are also 
affected, due to similar design.
    After that [DGAC] AD was issued, prompted by new findings, a 
specific inspection programme for A310 aeroplanes was introduced and 
required by DGAC France AD 1999-237-285(B) [which corresponds to 
certain actions in FAA AD 2000-12-12, Amendment 39-11790 (65 FR 
39072, June 23, 2000)], which was subsequently superseded by EASA AD 
2008-0008 [http://ad.easa.europa.eu/blob/easa_ad_2008_0008_superseded.pdf/AD_2008-0008_1], which introduced new thresholds 
and intervals in the frame of the A310 extended service goal 
exercise.
    Some cracks, which were discovered after the implementation of 
the preventive modification, prompted Airbus to perform a new 
Fatigue and Damage Tolerance analysis with a refined model of the 
area with and without repair or preventive reinforcement before 
crack appearance. Based on the results of this analysis, Airbus 
revised the related Service Bulletins to introduce more restrictive 
thresholds and intervals for curative and preventive repair 
configuration.
    EASA issued AD 2013-0014 [http://ad.easa.europa.eu/blob/easa_ad_2013_0214.pdf/AD_2013-0014_1], which superseded DGAC France 
AD 1992-049-130(B) and EASA AD 2008-0008, to mandate a new 
inspection programme [including related investigative and corrective 
actions].
    After EASA AD 2013-0014 was issued, further analysis allowed to 
identify one A300 aeroplane model and one retrofitted A300 MSN 
[manufacturer serial number] missing in the applicability chapter.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2013-0014, which is superseded, and 
clarifies the Applicability section and adds one A300 model and one 
A300 MSN.

The unsafe condition is fatigue cracking, which could result in reduced 
structural integrity of the lower spar of the nacelle pylon. Related 
investigative actions include additional eddy current and liquid 
penetrant inspections for cracking. Corrective actions include 
repairing cracking. For certain cracking lengths, repairs are described 
as reinforcing the lower spar with a doubler. 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-2013-1066.

Relevant Service Information

    Airbus has issued the following service bulletins. The actions 
described in these service bulletins are intended to correct the unsafe 
condition identified in the MCAI.
     Airbus Mandatory Service Bulletin A300-54-0071, Revision 
04, dated April 11, 2013 (for Model A300 B2-203, B2K-3C, B4-103, B4-
203, and B4-2C airplanes).
     Airbus Mandatory Service Bulletin A300-54-6011, Revision 
03, dated June 23, 2011 (for Model A300 B4-620, B4-622, and B4-622R 
airplanes).
     Airbus Mandatory Service Bulletin A310-54-2016, Revision 
06, dated January 16, 2013 (for Model A310-221, -222, -322, -324, and -
325 airplanes).
    The initial inspection compliance times for pre-repair and pre-
modification airplanes range between 3,300 total flight cycles or 6,600 
total flight hours, whichever occurs first; and 9,000 total flight 
cycles; depending on airplane configuration. The repetitive inspection 
interval is 2,300 flight cycles or 4,700 flight hours, whichever occurs 
first; or 2,500 flight cycles, depending on airplane configuration.
    The inspection compliance times for post-modification airplanes 
range between 5,100 total flight cycles and 10,200 total flight hours, 
whichever occurs first after the modification; and between 12,300 and 
15,700 total flight hours, whichever occurs later after the 
modification; depending on airplane configuration. The repetitive 
inspection interval ranges between 8,700 total flight cycles and 9,800 
total flight hours, whichever occurs first; and between 12,200 total 
flight cycles and 23,400 total flight hours, whichever occurs first; 
depending on airplane configuration.

[[Page 79335]]

    The inspection compliance times for post-repair airplanes range 
between 2,100 flight cycles and 6,900 flight hours, whichever occurs 
first after the repair; and between 7,600 flight cycles and 13,600 
flight hours, whichever occurs later after the repair; depending on 
airplane configuration. The repetitive inspection interval ranges 
between 2,100 flight cycles and 2,700 flight hours, whichever occurs 
first; and between 4,300 flight cycles and 14,700 flight hours, 
whichever occurs first; depending on airplane configuration.

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.
    In many FAA transport ADs, when the service information specifies 
to contact the manufacturer for further instructions if certain 
discrepancies are found, we typically include in the AD a requirement 
to accomplish the action using a method approved by either the FAA or 
the State of Design Authority (or its delegated agent).
    We have recently been notified that certain laws in other countries 
do not allow such delegation of authority, but some countries do 
recognize design approval organizations. In addition, we have become 
aware that some U.S. operators have used repair instructions that were 
previously approved by a State of Design Authority or a Design Approval 
Holder (DAH) as a method of compliance with this provision in FAA ADs. 
Frequently, in these cases, the previously approved repair instructions 
come from the airplane structural repair manual or the DAH repair 
approval statements that were not specifically developed to address the 
unsafe condition corrected by the AD. Using repair instructions that 
were not specifically approved for a particular AD creates the 
potential for doing repairs that were not developed to address the 
unsafe condition identified by the MCAI AD, the FAA AD, or the 
applicable service information, which could result in the unsafe 
condition not being fully corrected.
    To prevent the use of repairs that were not specifically developed 
to correct the unsafe condition, this proposed AD would require that 
the repair approval specifically refer to the FAA AD. This change is 
intended to clarify the method of compliance and to provide operators 
with better visibility of repairs that are specifically developed and 
approved to correct the unsafe condition. In addition, we use the 
phrase ``its delegated agent, or by the DAH with State of Design 
Authority design organization approval, as applicable'' in this 
proposed AD to refer to an DAH authorized to approve required repairs 
for this proposed AD.

Differences Between This Proposed AD and the MCAI or Service 
Information

    Although the MCAI and Airbus service information allow further 
flight after cracks are found during compliance with the required 
action, the new actions of this proposed AD would not permit further 
flight if cracks are detected in the lower nacelle pylon spar. We have 
determined that, because of the safety implications and consequences 
associated with that cracking, any cracked lower pylon spar must be 
repaired or modified before further flight. This difference has been 
coordinated with the EASA.

Costs of Compliance

    We estimate that this proposed AD affects 91 airplanes of U.S. 
registry.
    The actions that are required by AD 2000-12-12, Amendment 39-11790 
(65 FR 39072, June 23, 2000), and retained in this proposed AD take 
about 4 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 2000-12-12 is $340 per product.
    We also estimate that it would take about 12 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 $92,820, or $1,020 
per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 60 work-hours and require parts costing $1,680, for a cost 
of $6,780 per product. 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 proposed 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
