Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0051, dated March 2, 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 C-212-
CB, C-212-CC, C-212-CD, C-212-CE, and C-212-DF airplanes. The MCAI 
states:

    Failures were reported of the rudder pedal control system 
support on CASA C-212 aeroplanes. Subsequent investigation revealed 
that the welding area of the affected support structure had broken.
    This condition, if not corrected, could lead to failure of the 
rudder [pedal] control system, possibly resulting in reduced control 
of the aeroplane.
    To address this potential unsafe condition, EADS-CASA issued the 
SB [EADS-CASA Service Bulletin SB-212-27-0057, dated May 21, 2014] 
to provide modification instructions and EASA issued AD 2017-0036 
[which corresponds to FAA AD 2017-19-08, Amendment 39-19038 (82 FR 
43835, September 20 2017) (``AD 2017-19-08'')] to require that 
modification [of the rudder pedal adjustment system]. During 
accomplishment of that modification, several operators reported 
difficulties or impossibility to follow the accomplishment 
instruction. Consequently, EASA and Airbus D&S [Defense and Space 
S.A.] reviewed the difficulty reports and decided that the 
modification instructions have to be improved.
    Pending the improvement of the instructions of the SB [EADS-CASA 
Service Bulletin SB-212-27-0057, dated May 21, 2014] and in order to 
reduce the risk of failure of the [rudder] pedal adjustment system 
to an acceptable level, Airbus D&S issued the inspection AOT [Airbus 
Alert Operators Transmission AOT-C212-27-0002, dated February 28, 
2018] to provide instructions to repetitively inspect the affected 
parts [rudder pedal support box Part Number (P/N) 212-46195.1 and 
shaft P/N 212-46120-20].
    For the reasons described above, this [EASA] AD cancels the 
requirements of EASA AD 2017-0036, which is superseded, and requires 
repetitive [detailed visual] inspections of the rudder pedal 
adjustment system [rudder pedal support box P/N 212-46195.1 and 
shaft P/N 212-46120-20] and, depending on findings, accomplishment 
of applicable corrective action(s).
    This [EASA] AD is considered to be an interim action and further 
[EASA] AD action may follow.

    Corrective actions include obtaining corrective actions approved by 
the Manager, International Section, Transport Standards Branch, FAA; or 
EASA; or Airbus Defense and Space S.A.'s EASA Design Organization 
Approval (DOA); and accomplishing the corrective actions within the 
compliance time specified therein. 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-2018-0552.

Relationship Between Proposed AD and AD 2017-19-08

    This NPRM does not propose to supersede AD 2017-19-08. Rather, we 
have determined that a stand-alone AD would be more appropriate to 
address the changes in the MCAI. This proposed AD would require 
repetitive detailed visual inspections of the rudder pedal control 
system support box and shaft and applicable corrective actions. 
Accomplishment of the proposed actions would then terminate all of the 
requirements of AD 2017-19-08.

Related Service Information Under 1 CFR Part 51

    Airbus Defense and Space S.A. has issued Airbus Alert Operators 
Transmission AOT-C212-27-0002, dated February 28, 2018. The service 
information describes procedures for repetitive detailed visual 
inspections of the rudder pedal control system support box and shaft. 
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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our

[[Page 29478]]

bilateral agreement with the State of Design Authority, we have been 
notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 36 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
               Labor cost                   Parts cost         Cost per  product        Cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
Up to 8 work[dash]hours x $85 per hour =              $0  Up to $680................  Up to $24,480.
 Up to $680.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition repair specified in this proposed 
AD.

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 proposed 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 to the Director of the System Oversight 
Division.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.
