Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) for certain Airbus Model A330-200 and -300 series airplanes; and 
Model A340-200 and -300 series airplanes. The NPRM proposed to 
supersede AD 2009-15-17 to continue to require inspections for damage 
to the protective treatments or any corrosion of all main landing gear 
(MLG) bogie beams, application of protective treatments, and corrective 
action if necessary. The NPRM also proposed to require modification of 
the MLG bogie beams, which would terminate the repetitive inspections 
for any modified bogie beam. The NPRM also proposed to allow optional 
methods of compliance for certain actions. The NPRM was prompted by 
reports of thin paint coats and paint degradation on enhanced MLG bogie 
beams, as well as reports that some airplanes have been inspected too 
early

[[Page 12415]]

and not re-inspected as needed. This action revises the NPRM by 
revising the compliance times and adding a one-time inspection for 
airplanes that have been inspected too early. We are proposing this 
supplemental NPRM (SNPRM) to detect and correct damage or corrosion of 
the MLG bogie beams, which could cause a runway excursion event, bogie 
beam detachment from the airplane, or MLG collapse, which could result 
in damage to the airplane and injury to the occupants. Since these 
actions impose an additional burden over that proposed in the NPRM, we 
are reopening the comment period to allow the public the chance to 
comment on these proposed changes.

DATES: We must receive comments on this SNPRM by April 21, 2014.

Discussion

    We issued an NPRM to amend 14 CFR part 39 by adding an AD that 
would apply to certain Airbus Model A330-200 and -300 series airplanes; 
and Model A340-200 and -300 series airplanes. The NPRM was published in 
the Federal Register on September 25, 2013 (78 FR 58978). The NPRM 
proposed to supersede AD 2009-15-17, Amendment 39-15980 (74 FR 37523, 
July 29, 2009), to require actions intended to address the unsafe 
condition for the specified products.

Actions Since Previous NPRM Was Issued

    Since we issued the NPRM (78 FR 58978, September 25, 2013), we have 
received reports that some airplanes were initially inspected too early 
(before 4.5 years since the airplane's first flight with a bogie beam 
installed or since the bogie was installed after overhaul) and have not 
been re-inspected. The European Aviation Safety Agency (EASA), which is 
the Technical Agent for the Member States of the European Community, 
has issued EASA Airworthiness Directive 2013-0267, dated November 6, 
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:

    The operator of an A330 aeroplane (which has a common bogie beam 
with the A340) reported a fracture of the Right Hand (RH) main 
landing gear (MLG) bogie beam, which occurred while turning during 
low speed taxi maneuvers. The bogie fractured aft of the pivot point 
and remained attached to the sliding tube by the brake torque 
reaction rods. After this RH bogie failure, the aeroplane continued 
for approximately 40 meters on the forks of the sliding member 
before coming to rest on the taxiway.
    The investigations revealed that this event was due to corrosion 
pitting occurring on the bore of the bogie beam.
    This condition, if not detected and corrected, could lead to a 
runway excursion event or to detachment of the bogie from the 
aeroplane, or to MLG collapse, possibly resulting in damage to the 
aeroplane and injury to the occupants.
    To enable early detection and repair of corrosion of the 
internal surfaces, EASA issued AD 2007-0314 [http://ad.easa.europa.eu/ad/2007-0314R1] to require a one-time inspection 
of all MLG bogie beams, except Enhanced MLG bogie beams, and the 
reporting of the results to Airbus. EASA AD 2007-0314 was revised 
and later superseded by EASA AD 2008-0093 [http://ad.easa.europa.eu/ad/2008-0093], reducing the inspection threshold period.
    The results of subsequent investigations showed thin paint coats 
and paint degradation, confirmed as well on Enhanced MLG bogie 
beams. To address this additional concern, EASA issued AD 2011-0141 
[http://ad.easa.europa.eu/ad/2011-0141] [which was not mandated by 
the FAA], retaining the requirements of EASA AD 2008-0093, which was 
superseded, to require a one-time visual inspection of all MLG bogie 
beams, including a visual examination of the internal diameter for 
corrosion or damage to protective treatments of the bogie beam and 
measurement of the paint thickness on the internal bore, 
accomplishment of the applicable corrective actions and a 
modification of the MLG bogie beam to improve the coat paint 
application method, and application of corrosion protection.
    Prompted by in-service requests, EASA issued EASA AD 2012-0015 
[http://ad.easa.europa.eu/ad/2012-0015] [corresponds with FAA NPRM 
(78 FR 58978, September 25, 2013)] retaining the requirements of 
EASA AD 2011-0141, which was superseded, and introducing repetitive 
inspections of the MLG bogie beams [for damage to protective 
treatments or corrosion], which allows extension of the compliance 
time for the MLG bogie beam modification [for improved protection 
from corrosion] from 15 years to 21 years.

[[Page 12416]]

Modification of a MLG bogie beam constitutes terminating action for 
the repetitive inspections for that MLG bogie beam.
    Reports on inspection results provided to Airbus show that some 
aeroplanes were initially inspected too early (before 4.5 years 
since aeroplane first flight with bogie beam installed/installed 
after overhaul) and have not been re-inspected as required.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2012-0015, which is superseded, and 
redefines the inspection periodicity. This [EASA] AD also introduces 
a specific one-time inspection for aeroplanes that have been 
inspected too early.

    This proposed AD also provides optional methods of compliance for 
inspections for corrosion and damage to the protective treatment, 
repairs, and modification, of both MLG bogie beams. You may examine the 
MCAI in the AD docket on the Internet at http://regulations.gov by 
searching and locating it in Docket No. FAA-2013-0828.

Comments

    We gave the public the opportunity to comment on the NPRM (78 FR 
58978, September 25, 2013). The following presents the comments 
received on the NPRM and the FAA's response to each comment.

Request To Replace Modification 58896 With Modification 54500

    Delta Air Lines Inc. and US Airways requested that paragraph (h) of 
the NPRM (78 FR 58978, September 25, 2013) be changed to replace 
Modification 58896 with Modification 54500. The commenters stated that 
paragraph (h) of the NPRM specifies doing repetitive inspections on 
airplanes having all serial numbers, except airplanes on which 
Modification 58896 has been embodied in production; however, paragraph 
(g) of the NPRM and AD 2009-15-17, Amendment 39-15980 (74 FR 37523, 
July 29, 2009) are not applicable to airplanes with Modification 54500 
embodied in production.
    We agree with the commenters for the reasons provided. We have 
revised the affected airplanes specified in paragraph (g) of this SNPRM 
(paragraph (h) of the NPRM (78 FR 58978, September 25, 2013)). 
Paragraph (g) of this SNPRM affects airplanes and MLGs having one of 
the configurations specified below:
     Airbus Modification 54500 not embodied in production.
     Airbus Service Bulletin A330-32-3212; or A340-32-4256 not 
embodied in service.
     Airbus Service Bulletin A330-32-3222; or A340-32-4265 
embodied in service.

Request To Require Reporting Requirements Only For Positive Findings

    Delta Air Lines Inc. (Delta) requested that reporting be mandated 
only for positive findings, specifically for the findings beyond the 
applicable component maintenance manual repair limits.
    We disagree with the request to report only positive findings. All 
findings (positive and negative) must be reported to provide the 
manufacturer with information regarding the extent of the problem in 
the affected fleet, and to help determine whether a design change of 
the affected airplane part is needed. No change has been made to this 
SNPRM in this regard.

Request To Extend the Compliance Time for Reporting Requirements

    Delta requested that we extend the compliance time for reporting 
from 90 days to 180 days to allow findings to be batched together for a 
grouped report, and to preclude undue compliance issues related to late 
reporting.
    We do not agree with the request to extend the compliance time for 
reporting. Prompt reporting will ensure the timely update of the 
operator's maintenance documentation. However, under the provisions of 
paragraph (q) of this SNPRM, we will consider requests for approval of 
an extension of the compliance time if sufficient data are submitted to 
substantiate that the new compliance time would provide an acceptable 
level of safety. No change has been made to this SNPRM in this regard.

Request To Allow Use of Reporting Sheet in Messier-Dowty Service 
Bulletin A33/34-32-278, dated February 17, 2010

    Delta stated that the NPRM (78 FR 58978, September 25, 2013) 
specifies using the reporting sheet in Airbus Service Bulletin A330-32-
3237, dated January 18, 2011; however, this service bulletin does not 
have a reporting sheet included. Delta requested that we allow the use 
of the reporting sheet included in Messier-Dowty Service Bulletin A33/
34-32-278, dated February 17, 2010 instead.
    We disagree with the request. Airbus Service Bulletin A330-32-3237, 
Revision 01, dated October 14, 2011, includes a reporting sheet that is 
required by this AD. No change has been made to this SNPRM in this 
regard.

Other Changes to This SNPRM

    We have revised the affected airplanes for paragraph (k) of this 
SNPRM (paragraph (i) in the NPRM (78 FR 58978, September 25, 2013)). 
All airplanes are affected by the actions specified by paragraph (k) of 
this SNPRM.

FAA's Determination and Requirements of This SNPRM

    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.
    Certain changes described above expand the scope of the NPRM (78 FR 
58978, September 25, 2013). As a result, we have determined that it is 
necessary to reopen the comment period to provide additional 
opportunity for the public to comment on this SNPRM.

[[Page 12417]]

Differences Between This SNPRM and the MCAI or Service Information

    This SNPRM differs from the MCAI and/or service information as 
follows: The MCAI specifies repair and corrective actions in accordance 
with Airbus Mandatory Service Bulletin A330-32-3225, Revision 02, dated 
October 26, 2012; or A340-32-4268, Revision 03, dated January 14, 2013. 
However, Airbus Mandatory Service Bulletins A330-32-3225, Revision 02, 
dated October 26, 2012; and A340-32-4268, Revision 03, dated January 
14, 2013; do not describe those actions. Paragraph (j)(2) of this SNPRM 
specifies repair and corrective actions in accordance with Messier-
Dowty Service Bulletin A33/34-32-272, Revision 1, including Appendices 
A, B, C, and D, dated September 22, 2008. In addition, we refer to 
Messier-Dowty Service Bulletin A33/34-32-272, Revision 1, including 
Appendices A, B, C, and D, dated September 22, 2008, in paragraph 
(j)(1) of this AD for applying the protective treatments. This has been 
coordinated with Airbus.

Costs of Compliance

    We estimate that this SNPRM affects 51 airplanes of U.S. registry.
    We also estimate that it would take up to 34 work-hours per product 
to comply with the basic requirements of this SNPRM. The average labor 
rate is $85 per work-hour. Required parts would cost about $2,890 per 
product. Based on these figures, we estimate the cost of this SNPRM on 
U.S. operators to be $147,390, or $2,890 per product.
    In addition, we estimate that the optional modification would take 
about 10 work-hours and require parts costing $0, for a cost of $850 
per product. We have no way of determining the number of aircraft that 
might need the corrective action.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.

following new AD:

Airbus: Docket No. FAA-2013-0828; Directorate Identifier 2012-NM-
036-AD.

(a) Comments Due Date

    We must receive comments by April 21, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A330-201, -202, -203, -223, -
223F, -243, -243F, -301, -302, -303, -321, -322, -323, -341, -342, 
and -343 airplanes; and Model A340-211, -212, -213, -311, -312, and

serial numbers, except those airplanes on which Airbus Modification 
58896 has been embodied in production.

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
gear.

(e) Reason

    This AD was prompted by reports of thin paint coats and paint 
degradation on enhanced main landing gear (MLG) bogie beams. We are 
issuing this AD to detect and correct damage or corrosion of the MLG 
bogie beams, which could cause a runway excursion event, bogie beam 
detachment from the airplane, or MLG collapse, which could result in 
damage to the airplane and injury to the occupants.

(f) Compliance

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

(g) Repetitive Inspections for Certain Airplane Configurations

    For airplanes and MLGs having one of the configurations 
specified in paragraphs (g)(1), (g)(2), or (g)(3) of this AD: After 
54 months at the earliest, but no later than 72 months, since the 
left-hand (LH) or right-hand (RH) MLG bogie beam's first flight on 
an airplane, or since its first flight on an airplane after 
overhaul, as applicable: Clean the internal bore and do a detailed 
inspection for corrosion and damage to the protective treatments, 
and measure the paint thickness on the internal bore of the internal 
surfaces of the LH and RH MLG bogie beams, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A330-32-3225, 
Revision 02, dated October 26, 2012; or Airbus Service Bulletin 
A340-32-4268, Revision 03, dated January 14, 2013; as

[[Page 12418]]

applicable. Repeat the inspections thereafter at intervals of no 
less than 54 months, but no more than 72 months after the most 
recent inspection. During overhaul of a MLG bogie beam, any 
corrosion will be removed, which means that the first inspection 
after overhaul of that bogie beam, as required by this paragraph, is 
between 54 months and 72 months after that overhaul.
    (1) Airbus Modification 54500 not embodied in production.
    (2) Airbus Service Bulletin A330-32-3212; or A340-32-4256 not 
embodied in service.
    (3) Airbus Service Bulletin A330-32-3222; or A340-32-4265 
embodied in service.

(h) Optional Methods of Compliance for Certain Airplane Configurations

    Inspections and corrective actions on both MLG bogie beams done 
in accordance with the instructions of Messier-Dowty Service 
Bulletin A33/34-32-271, Revision 1, dated November 16, 2007; or A33/
34-32-272, Revision 1, dated September 22, 2008, as applicable, are 
acceptable methods of compliance for the requirements of paragraph 
(g) of this AD, provided each inspection is accomplished between 54 
months and 72 months since the first flight of the affected MLG 
bogie beam on an airplane, or since its first flight after its last 
overhaul, as applicable.

(i) One-Time Specific Inspection for Certain Airplane Configurations

    For airplanes on which the modification specified in paragraph 
(k) or (m)(2) of this AD, or the inspection specified in paragraph 
(m)(1) of this AD, has not been done as of the effective date of 
this AD, and on which a LH or RH MLG bogie beam has been inspected 
earlier than 4.5 years since first flight of the affected MLG bogie 
beam, or since the bogie beam's first flight after the bogie beam's 
last overhaul, in accordance with the Accomplishment Instructions of 
Airbus Service Bulletin A330-32-3225 or A340-32-4268: At the 
applicable time specified in paragraph (i)(1), (i)(2), or (i)(3) of 
this AD, clean the internal bore and do a detailed inspection of 
internal surfaces of the LH and RH MLG bogie beams to detect 
corrosion, damage to the protective treatments, and to measure the 
paint thickness on the internal bore, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A330-32-3225, 
Revision 02, dated October 26, 2012; or Airbus Service Bulletin 
A340-32-4268, Revision 03, dated January 14, 2013; as applicable.
    (1) For MLG bogie beams having the configurations specified in 
both paragraphs (i)(1)(i) and (i)(1)(ii) of this AD: Do the one-time 
specific inspection specified in paragraph (i) of this AD within 9 
months after the effective date of this AD.
    (i) MLG bogie beams having between 4.5 years and 10 years since 
first flight on an airplane, or since first flight on an airplane 
since overhaul.
    (ii) MLG bogie beam on which the first inspection was done after 
4 years and 3 months and before 4 years and 6 months since first 
flight of the MLG bogie beam, or since the bogie beam's first flight 
after last overhaul, as applicable.
    (2) For MLG bogie beams having the configurations specified in 
both paragraphs (i)(2)(i) and (i)(2)(ii) of this AD: Do the one-time 
specific inspection specified in paragraph (i) of this AD within 3
