Airworthiness Directives; Airbus Defense and Space S.A. (Formerly 
Known as Construcciones Aeronauticas, S.A.) Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus Defense and Space S.A. Model CN-235, CN-235-200 and CN-235-300 
airplanes. This AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. This AD requires 
revising the maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations. We are 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective January 22, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of January 22, 
2019.

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 certain Airbus Defense and 
Space S.A. Model CN-235, CN-235-200 and CN-235-300 airplanes. The NPRM 
published in the Federal Register on October 9, 2018 (83 FR 50539). The 
NPRM was prompted by a determination that new or more restrictive 
airworthiness limitations are necessary. The NPRM proposed to require 
revising the maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations.
    We are issuing this AD to address fatigue cracking, damage, and 
corrosion in principal structural elements; such fatigue cracking, 
damage, and corrosion could result in reduced structural integrity of 
the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0134, dated June 25, 2018 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Airbus Defense and Space S.A. Model CN-
235, CN-235-200, and CN-235-300 airplanes. The MCAI states:

    The airworthiness limitations and/or certification maintenance 
instructions for the EADS-CASA CN-235 aeroplanes, which are approved 
by EASA, are currently defined and published in the Airbus D&S CN-
235 ALL [Airworthiness Limitations List] DT-86-3001 document. These 
instructions have been identified as mandatory for continued 
airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition [i.e., fatigue cracking, damage, and corrosion in 
principal structural elements, which could result in reduced 
structural integrity of the airplane].
    For the reason described above, this [EASA] AD requires 
accomplishment of the actions specified in the ALL.

    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-
0805.

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.

Related Service Information Under 1 CFR Part 51

    Airbus Defence and Space has issued Technical Document DT-86-3001, 
CN-235 Airworthiness Limitations List, Issue R, dated March 20, 2018. 
This service information describes airworthiness limitations for 
airplane systems, structural inspections, safe life structural items, 
and safe life system items.
    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 9 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:
    We have determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although we 
recognize that this number may vary from operator to operator. In the 
past, we have estimated that this action takes 1 work-hour per 
airplane. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), we

[[Page 64442]]

have determined that a per-operator estimate is more accurate than a 
per-airplane estimate. Therefore, we estimate the total cost per 
operator to be $7,650 (90 work-hours x $85 per work-hour).

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

    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.
