Airworthiness Directives; Airbus SAS Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2017-07-05, 
which applied to all Airbus SAS Model A300 series airplanes; and Model 
A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-
605R Variant F airplanes (collectively called Model A300-600 series 
airplanes). AD 2017-07-05 required repetitive detailed visual 
inspections of the main landing gear (MLG) leg components and 
replacement of the MLG leg if cracked components are found. This AD 
retains the requirements of AD 2017-07-05 and removes the credit for 
doing an MLG overhaul in lieu of the initial inspection of the MLG leg 
components. This AD was prompted by further investigation after AD 
2017-07-05 was issued, which revealed that overhaul of the MLG does not 
alleviate the need for inspecting the MLG hinge arm/barrel pin for 
cracking. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective March 29, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 29, 
2019.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2017-07-05, Amendment 39-18843 (82 FR 16101, 
April 3, 2017) (``AD 2017-07-05''). AD 2017-07-05 applied to all Airbus 
SAS Model A300 series airplanes; and Model A300-600 series airplanes. 
The NPRM published in the Federal Register on November 6, 2018 (83 FR 
55498). The NPRM was prompted by further investigation after AD 2017-
07-05 was issued, which revealed that overhaul of the MLG does not 
alleviate the need for inspecting the MLG hinge arm/barrel pin for 
cracking. The NPRM proposed to retain the requirements of AD 2017-07-05 
and remove the credit for doing an MLG overhaul in lieu of the initial 
inspection of the MLG leg components. We are issuing this AD to address 
cracking of certain components in the MLG leg, which could result in an 
MLG collapse, and consequent damage to the airplane and injury to the 
airplane occupants.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0170, dated August 6, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A300 series 
airplanes; and Model A300-600 series airplanes. The MCAI states:

    Two cases were reported of finding a cracked MLG hinge arm/
barrel pin, one was discovered in service during a maintenance

[[Page 5596]]

task and the other one was identified during MLG overhaul.
    This condition, if not detected and corrected, could lead to MLG 
collapse, possibly resulting in damage to the aeroplane and injury 
to occupants.
    To address this potential unsafe condition, Airbus issued [Alert 
Operators Transmission] AOT A32W008-16 (original issue) to provide 
instructions for detailed visual inspections (DET) to detect cracks 
and EASA issued AD 2016-0058 accordingly [which corresponds to FAA 
AD 2017-07-05], requiring repetitive DET of the affected parts and, 
depending on findings, replacement of the affected MLG leg.
    Since that [EASA] AD was issued, further investigation results 
highlighted that, the overhaul of the MLG cannot alleviate the 
inspection need of the hinge arm/barrel pin.
    For the reasons described above, this [EASA] AD retains the 
requirement of EASA AD 2016-0058, which is superseded, removing the 
credit of MLG overhaul for the first inspection of the pin.

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-2018-
0907.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We have considered the comments received. Air Line 
Pilots Association, International and Madeline Roach each indicated 
support for the NPRM.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this final rule 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 for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Alert Operators Transmission (AOT) A32W008-16, 
Rev 01, dated July 30, 2018. This service information describes 
procedures for inspecting the MLG hinge arm/barrel pin for cracking, 
and replacement of the MLG leg if cracking is detected.
    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.

Costs of Compliance

    We estimate that this AD affects 128 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
          Labor cost              Parts cost    Cost per product              Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour =                $0  $85, per          $10,880, per inspection cycle.
 $85, per inspection cycle.                      inspection
                                                 cycle.
----------------------------------------------------------------------------------------------------------------


                                     Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
              Labor cost                         Parts cost                        Cost per product
----------------------------------------------------------------------------------------------------------------
20 work-hours x $85 per hour = $1,700  $3,400,000 per MLG...........  $3,401,700 per MLG.
 per MLG.
----------------------------------------------------------------------------------------------------------------

    We estimate that it will take about 1 work-hour per product to 
comply with the reporting requirement in this AD. The average labor 
rate is $85 per hour. Based on these figures, we estimate the cost of 
reporting the inspection results on U.S. operators to be $85 per 
product.
    The new requirements of this AD add no additional economic burden.

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

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.

[[Page 5597]]

    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.
