80 FR 34098 - Airworthiness Directives; Airbus Airplanes

DEPARTMENT OF TRANSPORTATION

Federal Register Volume 80, Issue 114 (June 15, 2015)

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter, A330-200, A330-300, A340-200, and A340-300 series airplanes. This proposed AD was prompted by reports that the inner bore of some main landing gear (MLG) unit bogie beams were insufficiently re-protected against corrosion after inspection or maintenance actions were accomplished. This proposed AD would require, for certain MLG units, determining which revision of the component maintenance manual (CMM) was used to accomplish the most recent MLG unit overhaul; a detailed inspection for missing or damaged paint, and if necessary, a detailed inspection of the cadmium plating for discrepancies, measurement of the depth of the cadmium plating, a general visual inspection of the base metal for corrosion or damage, a detailed inspection of repaired areas for cracking or corrosion; and corrective actions if necessary. We are proposing this AD to detect and correct corrosion in the bore of each MLG unit bogie beam, which could result in collapse of a MLG unit, and subsequent damage to the airplane and injury to occupants.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A330-200 Freighter, A330-200, A330-300, A340-200, 
and A340-300 series airplanes. This proposed AD was prompted by reports 
that the inner bore of some main landing gear (MLG) unit bogie beams 
were insufficiently re-protected against corrosion after inspection or 
maintenance actions were accomplished. This proposed AD would require, 
for certain MLG units, determining which revision of the component 
maintenance manual (CMM) was used to accomplish the most recent MLG 
unit overhaul; a detailed inspection for missing or damaged paint, and 
if necessary, a detailed inspection of the cadmium plating for 
discrepancies, measurement of the depth of the cadmium plating, a 
general visual inspection of the base metal for corrosion or damage, a 
detailed inspection of repaired areas for cracking or corrosion; and 
corrective actions if necessary. We are proposing this AD to detect and 
correct corrosion in the bore of each MLG unit bogie beam, which could 
result in collapse of a MLG unit, and subsequent damage to the airplane 
and injury to occupants.

DATES: We must receive comments on this proposed AD by July 30, 2015.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0222, dated October 6, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A330-200 Freighter, A330-200, A330-300, A340-200, and A340-300 series 
airplanes. The MCAI states:

    From in-service experience, it was found that the inner bore of 
some bogie beams had been insufficiently re-protected against 
corrosion after inspection and/or possible maintenance actions 
accomplished in this area (absence of corrosion inhibitor and damage 
to paint have been found in some specific areas).
    This condition, if not detected and corrected, could lead to 
corrosion on the bore of the bogie beam, potentially resulting in 
Main Landing Gear (MLG) collapse, ultimately resulting in damage to 
the aeroplane and injury to the occupants.
    To address this potential unsafe condition, Airbus issued Alert 
Operators Transmission (AOT) A32L004-14, providing inspection 
instructions for some aeroplane configurations.
    For the reasons described above, this [EASA] AD requires 
identification of the MLG units that are possibly affected, [a 
detailed] inspection [for missing or damaged paint] of the MLG Bogie 
Beam bore and, depending on findings, accomplishment of the 
applicable corrective actions.
    This [EASA] AD also prohibits the installation of MLG units that 
have been overhauled by using instructions from an earlier 
Components Maintenance Manual (CMM) revision.

Required actions also include a detailed inspection of the cadmium 
plating for discrepancies (gray in color), measurement of the depth of 
the cadmium plating if necessary, and a general visual inspection of 
the base metal for corrosion or damage, and a detailed inspection of 
repaired areas for cracking or corrosion. Corrective actions include 
removing cadmium plating and repairing any cracked, corroded, or 
damaged areas; re-applying cadmium plating and paint; and re-applying 
temporary corrosion protection to the bores of the MLG bogie beams.
    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-
1981.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Alert Operators Transmission A32L004-14, dated 
July 28, 2014, including Appendices 1, 2, 3, and 4, which are not 
dated. This service information describes procedures for inspections of 
the bogie beam bore of the MLG.
    Messier-Dowty has issued the following service information, which 
describes procedures for inspections of the internal diameter of the 
bogie beam for corrosion.
     Service Bulletin A33/34-32-272, including Appendices A, B, 
C, and D, dated November 16, 2007.
     Service Bulletin A33/34-32-272, Revision 1, including 
Appendices A, B, C, and D, dated September 22, 2008.
    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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 89 airplanes of U.S. 
registry.
    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 $90,780, or $1,020 
per product.
    We have received no definitive data that would enable us to provide 
cost estimates for any necessary follow-on actions.

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 proposed AD 
is 2120-0056. The paperwork cost associated with this proposed 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 proposed 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;

[[Page 34100]]

    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.
