Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2010-06-04, 
for certain Airbus Model A300 B2-1C, B2-203, B2K-3C, B4-103, B4-203, 
B4-2C airplanes; Model A310 series airplanes; Model A300 B4-600 series 
airplanes; and Model A300 B4-600R series airplanes. AD 2010-06-04 
required repetitive inspections to detect cracks of the pylon side 
panels (upper section) at rib 8; and corrective actions if necessary. 
This new AD continues to require repetitive inspections for cracking of 
the pylons 1 and 2 side panels (upper section) at rib 8 with reduced 
compliance times, and corrective actions if necessary. This AD also 
requires repetitive post-repair and post-modification inspections and 
repair if necessary. This AD also removes certain airplanes having a 
certain modification from the applicability. This AD was prompted by 
reports of cracks found on pylon side panels at rib 8 and a fleet 
survey and updated fatigue and damage tolerance analyses. We are 
issuing this AD to detect and correct cracking of pylon side panels 
(upper section) at rib 8, which could lead to reduced structural 
integrity of the pylon primary structure, which could cause detachment 
of the engine from the fuselage.

DATES: This AD becomes effective February 2, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 2, 
2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of April 
15, 2010 ((75 FR 11428, March 11, 2010); corrected May 4, 2010 (75 FR

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2010-06-04,

[[Page 81169]]

Amendment 39-16228 ((75 FR 11428, March 11, 2010); corrected May 4, 
2010 (75 FR 23572)). AD 2010-06-04 applied to certain Airbus Model A300 
B2-1C, B2-203, B2K-3C, B4-103, B4-203, B4-2C airplanes; Model A310 
series airplanes; Model A300 B4-600 series airplanes; and Model A300 
B4-600R series airplanes. The NPRM published in the Federal Register on 
September 22, 2014 (79 FR 56526).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0136R1, dated July 30, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition on certain Airbus Model 
A300 B2-1C, B2-203, B2K-3C, B4-103, B4-203, B4-2C airplanes; Model A310 
series airplanes; Model A300 B4-600 series airplanes; and Model A300 
B4-600R series airplanes. The MCAI states:

    Cracks were found on pylon side panels (upper section) at rib 8 
on Airbus A300, A310 and A300-600 aeroplanes equipped with General 
Electric engines. Investigation of these findings indicated that 
this problem was likely to also affect aeroplanes of this type 
design with other engine installations.
    This condition, if not detected and corrected, could lead to 
reduced strength of the pylon primary structure, possibly resulting 
in pylon structural failure and in-flight loss of an engine.
    Prompted by these findings, EASA issued AD 2008-0181 [http://www.regulations.gov/#!documentDetail;D=FAA-2009-0789-0002] [which 
corresponds to FAA AD 2010-06-04, Amendment 39-16228 ((75 FR 11428, 
March 11, 2010); corrected May 4, 2010 (75 FR 23572))] to require 
repetitive detailed visual inspections [of the pylon side panels 
(upper section) at rib 8] and, depending on aeroplane configuration 
and/or findings, the accomplishment of applicable corrective 
action(s).
    Since that [EASA] AD was issued, a fleet survey and updated 
Fatigue and Damage Tolerance analyses have been performed in order 
to substantiate the second A300-600 Extended Service Goal (ESG2) 
exercise. The results of these analyses have shown that the risk for 
these aeroplanes is higher than initially determined and 
consequently, the threshold and interval must be reduced to allow 
timely detection of these cracks and the accomplishment of 
applicable correction action(s).
    EASA issued AD 2013-0136 [http://ad.easa.europa.eu/ad/2013-0136R1] which retained the requirements of EASA AD 2008-0181, which 
was superseded, and required the inspections to be accomplished 
within reduced thresholds and intervals.
    After publication of EASA AD 2013-0136, it appeared that Airbus 
Mod 03599 had no influence on the aeroplane configuration affected 
by this AD. At the same time Airbus Service Bulletin (SB) A30-54-
6015 Revision 3 was not integrally taken into account as this 
revision no longer identifies configuration 3 aeroplanes.
    For the reasons described above, EASA [AD] 2013-0136 is revised 
to exclude Airbus Mod 03599 from the applicability and to delete the 
reference to the configuration 3 for A300-600 aeroplanes.

    Corrective actions include doing a repair. This AD also provides an 
optional modification (installing a doubler), which would terminate the 
repetitive inspections. Required actions also include repetitive post-
repair and post-modification inspections and repair if necessary. You 
may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0648-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (79 FR 
56526, September 22, 2014) and the FAA's response.

Request To Revise Method Used To Determine Compliance Times

    United Parcel Service (UPS) requested that we revise the proposed 
compliance times to be less complex. UPS stated that the proposed 
compliance times contain a method known as ``Average Flight Time'' 
(AFT) which results in a variable flight hour limit and adds 
unnecessary complexity to the threshold table and subsequent inspection 
actions. UPS added that use of the AFT method, along with a lack of 
standard procedures for implementing the AFT method would create 
uncertainty for operators and inspectors trying to determine the 
correct compliance time. UPS stated that in review of prior FAA ADs, 
including AD 98-18-02, Amendment 39-10718 (63 FR 45689, August 27, 
1998), that the FAA does not concur with the AFT compliance time 
methodology as ``. . . such adjustments may not address the unsafe 
condition in a timely manner'' and ``. . . they (AFT compliance times) 
do not fit into the AD tracking process for operators or for Principle 
Maintenance Inspectors (PMIs) attempting to ascertain compliance with 
ADs.''
    UPS compiled a table of fixed compliance times that it suggested 
would be simpler to use instead of the proposed AFT-based compliance 
times.
    We disagree with the commenter's request to revise the compliance 
times in this AD. The compliance times, as proposed, use fixed flight-
cycle and flight-hour compliance times. For only Model A310 series 
airplanes, the compliance times depend on whether airplanes are short 
range or long range airplanes. We acknowledge that this causes 
additional complexity in tracking and forecasting airplane utilization; 
however, the inspection schedule was created by Airbus to offer 
operators the greatest flexibility. Operators may elect to inspect 
within the range that complies with both the long range and short range 
utilization in order to reduce the complexity. We have not changed this 
AD in this regard.
    Regarding AD 98-18-02, Amendment 39-10718 (63 FR 45689, August 27, 
1998), at the time the FAA issued AD 98-18-02, the required actions in 
Airbus Industrie Service Bulletin A300-57-6027, Revision 2, dated 
September 13, 1994, contained inspection thresholds and intervals based 
on airplane flight cycles, and provided instructions for adjusting the 
flight cycle threshold and interval using each individual airplane's 
AFT utilization. The FAA did not agree with the AFT method because it 
could result in a different inspection threshold and interval for each 
individual airplane, and the FAA did not agree with adjusting a flight 
cycle based threshold and interval using the average flight time 
utilization without also having a related flight hour based threshold 
and interval.

Conclusion

    We reviewed the available data, including the comment received, 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:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 56526, September 22, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 56526, September 22, 2014).

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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2014-0648; or in person at the 
Docket Management Facility between 9 a.m. and 5 p.m., Monday through 
Friday, except Federal holidays. The AD docket contains this AD, the 
regulatory evaluation, any comments received, and other information. 
The street address for the Docket Operations office (telephone 800-647-
5527) is in the ADDRESSES section.

(e) Reason

    This AD was prompted by reports of cracks found on pylon side 
panels at rib 8 and a fleet survey and updated fatigue and damage 
tolerance analyses. We are issuing this AD to detect and correct 
cracking of pylon side panels (upper section) at rib 8, which could 
lead to reduced structural integrity of the pylon primary structure, 
which could cause detachment of the engine from the fuselage.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Actions and Compliance With Revised Service Information

    This paragraph restates the requirements of paragraph (f) of AD 
2010-06-04, Amendment 39-16228 ((75 FR 11428, March 11, 2010); 
corrected May 4, 2010 (75 FR 23572)), with revised service 
information. Accomplishing the initial inspection required by 
paragraph (h) of this AD terminates the requirements of this 
paragraph.
