SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A330–200 Freighter series airplanes, Model A330– 200 series airplanes, Model A330–300 series airplanes, Model A340–200 series airplanes, Model A340–300 series airplanes, Model A340–500 series airplanes, and Model A340–600 series airplanes. The NPRM published in the Federal Register on May 9, 2018 (83 FR 21196). The NPRM was prompted by a report of deficient fatigue performance of high strength steel used in forgings. Components made from the affected high strength steel are installed on the MLG, NLG, and CLG. The NPRM proposed to require identifying the part number and serial number of certain components installed on the MLG, NLG, and CLG; replacing affected parts; identifying the airplane’s weight variant; and determining the applicable life limit for certain components installed on the MLG, NLG, and CLG. We are issuing this AD to address certain parts made from 300M high strength steel, which if uncorrected, could lead to structural failure of the landing gear, and possible loss of control of the airplane during take-off or landing. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017–0185, dated September 22, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus SAS Model A330–200 Freighter series airplanes, Model A330– 200 series airplanes, Model A330–300 series airplanes, Model A340–200 series airplanes, Model A340–300 series airplanes, Model A340–500 series E:\FR\FM\01OCR1.SGM 01OCR1 49270 Federal Register / Vol. 83, No. 190 / Monday, October 1, 2018 / Rules and Regulations airplanes, and Model A340–600 series airplanes. The MCAI states: In 2006, Messier-Dowty identified a deficiency in the fatigue performance of 300M high strength steel used in forgings. The root cause for this fatigue deficiency was the processing during preparation of the material. After investigation, it was determined that the following material sources (S) were affected by this fatigue deficiency: Electralloy (S1), RSM (S2A, S2B or S2C), Latrobe (S3) and Aubert et Duval (S4). Consequently, reduced lives were calculated for certain landing gear main fittings, bogie beams and sliding pistons, determined to be affected by the 300M material properties quality issue. These components are installed on Main, Nose and Centre Landing Gears (MLG, NLG, CLG) of A330 and A340 aeroplanes. This condition, if not corrected, could lead to structural failure of a landing gear, possibly resulting in loss of control of the aeroplane during take-off or landing. To initially address this potential unsafe condition, Airbus published reduced life limits for the affected parts from material sources S1, S2 and S3 in the applicable Airworthiness Limitation Section (ALS) Part 1. Later, it was determined that ALS Part 1 was an inappropriate place for recording the reduced lives and Airbus published Service Bulletin (SB) A330–32–3281, SB A340–32– 4310, and SB A340–32–5119, as applicable, to provide identification and replacement instructions for affected parts made of all material sources S1, S2, S3 and S4. This action was also accomplished to simplify Airbus ALS Part 1. For the reasons described above, this [EASA] AD requires [identification of the part numbers and serial numbers of the main fitting, bogie beam and sliding piston of the MLG, NLG, and CLG, and the airplane’s weight variant], and implementation of the reduced life limits for the affected parts and replacement of any parts that are close to, or have exceeded the applicable reduced life limit. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0395. Comments We gave the public the opportunity to participate in developing this final rule. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the relevant data 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.

Turbofan Engines Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. AGENCY: The FAA is superseding Airworthiness Directive (AD) 2018–10– 11 for all CFM International S.A. (CFM) Model CFM56–7B engines. AD 2018– 10–11 required initial and repetitive inspections of certain fan blades and, if they fail the inspection, their replacement with parts eligible for installation. This superseding AD requires the same initial and repetitive inspections but revises the compliance time for the repetitive inspections. This AD was prompted by further analysis by the manufacturer that indicated a need to reduce the repetitive fan blade inspection interval based on ongoing root cause investigation of an April 2018 engine failure. The agency is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective October 16, 2018. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 16, 2018.

Airworthiness Directives; Airbus SAS Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus SAS Model A330-200 Freighter, -200, and -300 series airplanes; 
and Airbus SAS Model A340-200, -300, -500, and -600 series airplanes. 
This AD was prompted by a report of deficient fatigue performance of 
high strength steel used in forgings. Components made from the affected 
high strength steel are installed on the main landing gear (MLG), nose 
landing gear (NLG), and center landing gear (CLG). This AD requires 
identifying the part number and serial number of certain components 
installed on the MLG, NLG, and CLG; replacing affected parts; 
identifying the airplane's weight variant; and determining the 
applicable life limit for certain components installed on the MLG, NLG, 
and CLG. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective November 5, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 5, 
2018.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Airbus Model A330-200 
Freighter series airplanes, Model A330-200 series airplanes, Model 
A330-300 series airplanes, Model A340-200 series airplanes, Model A340-
300 series airplanes, Model A340-500 series airplanes, and Model A340-
600 series airplanes. The NPRM published in the Federal Register on May 
9, 2018 (83 FR 21196). The NPRM was prompted by a report of deficient 
fatigue performance of high strength steel used in forgings. Components 
made from the affected high strength steel are installed on the MLG, 
NLG, and CLG. The NPRM proposed to require identifying the part number 
and serial number of certain components installed on the MLG, NLG, and 
CLG; replacing affected parts; identifying the airplane's weight 
variant; and determining the applicable life limit for certain 
components installed on the MLG, NLG, and CLG.
    We are issuing this AD to address certain parts made from 300M high 
strength steel, which if uncorrected, could lead to structural failure 
of the landing gear, and possible loss of control of the airplane 
during take-off or landing.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0185, dated September 22, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A330-200 Freighter 
series airplanes, Model A330-200 series airplanes, Model A330-300 
series airplanes, Model A340-200 series airplanes, Model A340-300 
series airplanes, Model A340-500 series

[[Page 49270]]

airplanes, and Model A340-600 series airplanes. The MCAI states:

    In 2006, Messier-Dowty identified a deficiency in the fatigue 
performance of 300M high strength steel used in forgings. The root 
cause for this fatigue deficiency was the processing during 
preparation of the material. After investigation, it was determined 
that the following material sources (S) were affected by this 
fatigue deficiency: Electralloy (S1), RSM (S2A, S2B or S2C), Latrobe 
(S3) and Aubert et Duval (S4).
    Consequently, reduced lives were calculated for certain landing 
gear main fittings, bogie beams and sliding pistons, determined to 
be affected by the 300M material properties quality issue. These 
components are installed on Main, Nose and Centre Landing Gears 
(MLG, NLG, CLG) of A330 and A340 aeroplanes.
    This condition, if not corrected, could lead to structural 
failure of a landing gear, possibly resulting in loss of control of 
the aeroplane during take-off or landing.
    To initially address this potential unsafe condition, Airbus 
published reduced life limits for the affected parts from material 
sources S1, S2 and S3 in the applicable Airworthiness Limitation 
Section (ALS) Part 1. Later, it was determined that ALS Part 1 was 
an inappropriate place for recording the reduced lives and Airbus 
published Service Bulletin (SB) A330-32-3281, SB A340-32-4310, and 
SB A340-32-5119, as applicable, to provide identification and 
replacement instructions for affected parts made of all material 
sources S1, S2, S3 and S4. This action was also accomplished to 
simplify Airbus ALS Part 1.
    For the reasons described above, this [EASA] AD requires 
[identification of the part numbers and serial numbers of the main 
fitting, bogie beam and sliding piston of the MLG, NLG, and CLG, and 
the airplane's weight variant], and implementation of the reduced 
life limits for the affected parts and replacement of any parts that 
are close to, or have exceeded the applicable reduced life limit.

    You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0395.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data 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.

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

[[Page 49271]]

delegated the authority to issue ADs applicable to transport category 
airplanes and associated appliances to the Director of the System 
Oversight Division.

Regulatory Findings

    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
