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.

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

[[Page 5357]]

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Defense and Space S.A. Model C-212 airplanes. This AD was 
prompted by multiple reports of damaged and cracked rudder torque tube 
shafts. This AD requires various repetitive inspections, and corrective 
actions if necessary. This AD also provides a modification which 
terminates the repetitive inspections. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD is effective February 22, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 22, 
2017.

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 C-212 airplanes. The NPRM published in the Federal 
Register on October 11, 2016 (81 FR 70062). The NPRM was prompted by 
multiple reports of damaged and cracked rudder torque tube shafts. The 
NPRM proposed to require repetitive general visual and high frequency 
eddy current (HFEC) inspections of the inner rudder torque tube shaft 
for cracks, deformation, and damage; repetitive detailed inspections, 
and HFEC inspections, if necessary, of the inner and outer rudder 
torque tube shaft for cracks, deformation, and damage; and corrective 
actions if necessary. We are issuing this AD to detect and correct 
damaged and cracked rudder torque tube shafts, which could lead to 
structural failure of the affected rudder torque tube shaft and 
possible 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 
2016-0052, dated March 14, 2016 (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 
C-212 airplanes. The MCAI states:

    Occurrences were reported of finding a damaged and cracked 
rudder torque tube shaft, Part Number (P/N) 212-46237-01. Subsequent 
investigation determined that this damage occurred after parking of 
the aeroplane during a heavy wind gust, without having set the 
flight control surfaces in locked position.
    This condition, if not detected and corrected, could lead to 
structural failure of the affected rudder torque tube shaft, 
possibly resulting in reduced control of the aeroplane.
    To address this potential unsafe condition, EADS-CASA issued 
Alert Operators Transmission (AOT) AOT-C212-27-0001 to provide 
inspection instructions, and Service Bulletin (SB) SB-212-27-0058 
providing modification instructions.
    For the reasons described above, this [EASA] AD requires 
repetitive inspections of the affected rudder torque tube shaft, and 
introduces an optional modification [replacement], which constitutes 
terminating action for those repetitive inspections.

    Required actions include repetitive general visual and HFEC 
inspections of the inner rudder torque tube shaft for cracks, 
deformation, and damage; repetitive detailed inspections, and HFEC 
inspections, if necessary, of the inner and outer rudder torque tube 
shaft for cracks, deformation, and damage; a general visual inspection 
to verify rudder alignment if necessary; and corrective actions if 
necessary. Repetitive inspections are done depending on conditions 
(wind conditions, gust lock engagement, and rudder deviation) 
identified in Airbus Defense & Space Alert Operators Transmission AOT-
C212-27-0001, Revision 0, dated July 15, 2015 (``AOT-C212-27-0001, Rev. 
0''). Damage may include bulging, dents, peeled paint, or visible 
corrosion. Corrective actions include replacement of the rudder torque 
tube shaft with a new rudder torque tube shaft, and repair. The 
optional terminating action includes replacement of the rudder torque 
tube shaft with an improved rudder torque tube shaft. 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-2016-9187.

Comments

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

Clarification of the Actions in Paragraph (g)(2) of the Proposed AD

    Paragraph (g)(2) of the proposed AD specifies to do inspections 
``after the conditions'' identified in paragraph 3.1.1.1 of AOT-C212-
27-0001, Rev. 0. We have revised paragraph (g)(2) of the AD to clarify 
the inspections are done after any weather event that includes the 
conditions identified in paragraph 3.1.1.1 of AOT-C212-27-0001, Rev. 0.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD with the change described 
previously and minor editorial changes. We have determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting 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

    We reviewed the following Airbus Defense and Space service 
information.
     EADS CASA Service Bulletin SB-212-27-0058, dated April 25, 
2014. This service information describes procedures for replacement of 
the rudder torque tube shaft with an improved rudder torque tube shaft.

[[Page 5358]]

     AOT-C212-27-0001, Rev. 0. This service information 
describes procedures for general visual and HFEC inspections of the 
inner rudder torque tube shaft for cracks, deformation, and damage; 
detailed inspections, and HFEC inspections, if necessary, of the inner 
and outer rudder torque tube shaft for cracks, deformation, and damage; 
a general visual inspection to verify rudder alignment; and corrective 
actions, if necessary.
    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.

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.
