14 CFR Part 39

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, and 
CN-235-300 airplanes. This AD was prompted by a report of cracks on the 
lugs of the inboard and outboard control rod fittings of the right hand 
(RH) and left hand (LH) side ailerons. This AD requires a one-time non-
destructive test (NDT) inspection of the inboard and outboard control 
rod fittings of the RH and LH side ailerons for cracks and corrosion, 
and repair if necessary. We are issuing this AD to detect and correct 
cracks and corrosion on the lugs of the inboard and outboard control 
rod fittings of the RH and LH side ailerons, which could lead to 
reduced controllability of the airplane.

DATE: This AD becomes effective May 3, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 3, 2016.

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, and CN-235-300 
airplanes. The NPRM published in the Federal

[[Page 17368]]

Register on September 28, 2015 (80 FR 58224). The NPRM was prompted by 
a report of cracks on the lugs of the inboard and outboard control rod 
fittings of the RH and LH side ailerons. The NPRM proposed to require a 
one-time NDT inspection of the inboard and outboard control rod 
fittings of the RH and LH side ailerons for cracks and corrosion, and 
repair if necessary. We are issuing this AD to detect and correct 
cracks and corrosion on the lugs of the inboard and outboard control 
rod fittings of the RH and LH side ailerons, which could lead to 
reduced controllability 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 
2015-0040, dated March 6, 2015 (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, and CN-235-300 airplanes. The MCAI states:

    A CN-235 operator recently reported finding, during scheduled 
maintenance tasks, cracks on the lugs of the control rod fittings 
(inboard and outboard) of the ailerons [Right Hand (RH) and Left 
Hand (LH) side] of two aeroplanes. At the time of the finding, the 
two affected aeroplanes had accumulated between 16 000 and 17 000 
flight hours (FH), around 6 000 flight cycles and had been in 
service for 20 years. Following the investigation results, it was 
determined that these cracks were due to stress corrosion.
    This condition, if not detected and corrected, could lead to 
aileron fittings failure, possibly resulting in reduced control of 
the aeroplane.
    To address this unsafe condition and verify the integrity of the 
fittings, EADS-CASA (Airbus Military) issued Alert Operators 
Transmission (AOT) CN235-57-0001 to provide instructions for a one-
time Non-Destructive (NDT) inspection of the affected fittings for 
cracks and corrosion.
    For the reasons described above, this [EASA] AD requires a one-
time NDT inspection of the affected aileron fittings and, if 
discrepancies are detected, accomplishment of applicable corrective 
action(s) [repair of any cracked or corroded parts].

    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-
3636.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 58224, September 
28, 2015) 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 AD 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 (80 FR 58224, September 28, 2015) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 58224, September 28, 2015).

Related Service Information Under 1 CFR Part 51

    Airbus Defense and Space S.A. has issued Airbus Military Alert 
Operators Transmission (AOT) AOT-CN235-57-0001, Revision 1, dated March 
14, 2014. The service information describes procedures for a one-time 
NDT inspection of the inboard and outboard control rod fittings of the 
RH and LH side ailerons for cracks and corrosion, and contacting Airbus 
Military for repair instructions. 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 24 airplanes of U.S. registry.
    We also estimate that it will take about 30 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $61,200, or $2,550 per product.

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 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.

unless already done.

(g) One-Time Non-Destructive Test (NDT) Inspection

    (1) At the later of the compliance times specified in paragraph 
(g)(1)(i) or (g)(1)(ii) of this AD: Do a one-time NDT inspection of 
the inboard and outboard control rod fittings of the RH and LH side 
ailerons for cracks, and a one-time general visual inspection for 
corrosion, in accordance with Airbus Military Alert Operators 
Transmission (AOT) AOT-CN235-57-0001, Revision 1, dated March 14, 
2014.
    (i) Before exceeding 8,000 flight hours or 10 years since first 
flight of the airplane, whichever occurs first.
    (ii) Within 3 months after the effective date of this AD.
    (2) If any crack or corrosion is found during any inspection 
required by paragraph (g)(1) of this AD, before further flight,
