We are adopting a new airworthiness directive (AD) for all Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, CN- 235-300, and C-295 airplanes. This AD was prompted by reports that cracks were found on the door mechanism actuator shaft assemblies of the nose landing gear (NLG). This AD requires repetitive inspections of the NLG door mechanism actuator shaft assemblies having certain part numbers, and corrective actions if necessary. This AD would also provide an optional terminating action for the repetitive inspections for Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes. We are issuing this AD to address the unsafe condition on these products.

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 all 
Airbus Defense and Space S.A. Model CN-235, CN-235-100, CN-235-200, CN-
235-300, and C-295 airplanes. This AD was prompted by reports that 
cracks were found on the door mechanism actuator shaft assemblies of 
the nose landing gear (NLG). This AD requires repetitive inspections of 
the NLG door mechanism actuator shaft assemblies having certain part 
numbers, and corrective actions if necessary. This AD would also 
provide an optional terminating action for the repetitive inspections 
for Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes. We 
are issuing this AD to address the unsafe condition on these products.

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 Defense and 
Space S.A. Model CN-235, CN-235-100, CN-235-200, CN-235-300, and C-295 
airplanes. The NPRM published in the Federal Register on June 4, 2018 
(83 FR 25587). The NPRM was prompted by reports that cracks were found 
on the door mechanism actuator shaft assemblies of the NLG. The NPRM 
proposed to require repetitive inspections of the NLG door mechanism 
actuator shaft assemblies having certain part numbers, and corrective 
actions if necessary. The NPRM also proposed to provide an optional 
terminating action for the repetitive inspections for Model CN-235, CN-
235-100, CN-235-200, and CN-235-300 airplanes. We are issuing this AD 
to address such cracking, which could lead to an in-flight NLG door 
opening and possibly result in detachment of the affected door, and 
consequent damage to, or reduced control 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 
2017-0181, dated September 18, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus Defense and Space S.A. Model 
CN-235, CN-235-100, CN-235-200, CN-235-300, and C-295 airplanes. The 
MCAI states:

    Cracks were reportedly found on nose landing gear (NLG) door 
actuator shaft assemblies on CN-235 aeroplanes. The subsequent 
design review determined that combined or multiple rupture of the 
affected shaft assembly could occur, without this being signalised 
to the flight crew.
    This condition, if not detected and corrected, could lead to an 
in-flight NLG door opening, possibly resulting in detachment of the 
affected door, with consequent damage to, or reduced control of, the 
aeroplane and injury to persons on the ground.
    To address this unsafe condition, Airbus Defence & Space (D&S) 
issued Alert Operators Transmissions AOT-CN235-32-0001 Revision 
(Rev.) 2 and AOT-C295-32-0001 Rev. 2 to provide inspection 
instructions.
    For the reasons described above, this [EASA] AD requires 
repetitive detailed (DET) or special detailed [rototest] inspections 
of the NLG door actuator shaft assembly, as applicable, and, 
depending on findings, corrective actions [including replacement of 
any cracked component, or cracked NLG door mechanism actuator shaft 
assembly with a serviceable part]. This [EASA] AD also introduces a 
modification for CN-235 aeroplanes as (optional) terminating action 
for the repetitive inspections as required by this [EASA] AD.

    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-
0493.

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 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.
