SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (SNPRM) 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; and Model C-295 airplanes. The SNPRM published in
the Federal Register on June 21, 2017 (82 FR 28274) (``the SNPRM''). We
preceded the SNPRM with a notice of proposed rulemaking that published
in the Federal Register on November 25, 2016 (81 FR 85169) (``the
NPRM''). The NPRM proposed to require an inspection of motorized cross-
feed fuel valves and, depending on findings, applicable corrective
action(s). The NPRM was prompted by leakage of a motorized cross-feed
fuel valve. The SNPRM proposed to require a reduced compliance time for
the initial inspection, the addition of repetitive inspections and
operational checks, and corrective actions if necessary. We are issuing
this AD to detect and correct leaks in a motorized fuel valve, which
could lead to failure of the fuel valve and consequent improper fuel
system functioning or, in case of the presence of an ignition source,
an airplane fire.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2017-0004, dated January 9, 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, and CN-235-300
airplanes; and Model C-295 airplanes. The MCAI states:
Leakage of a motorised cross-feed fuel valve Part Number (P/N)
7923227F was reported on a CN-235-100M aeroplane. The leakage was
observed through the valve electrical connectors and detected during
accomplishment of a functional check in accordance with task 28.007
of the CN-235 Maintenance Review Board Report (MRB CN-235-PV01).
Identical motorised fuel valves are installed on civilian CN-235 and
C-295 aeroplanes, as cross-feed, shut-off and defueling valves.
This condition, if not detected and corrected, could lead to
failure of a motorised fuel valve and consequent improper
functioning of the fuel system or, in case of an ignition source,
could lead to a fire, possibly resulting in damage to the aeroplane
and injury to occupants.
To address this potentially unsafe condition, Airbus Defence &
Space (D&S) issued Alert Operators Transmission (AOT)-CN235-28-0001
and AOT-C295-28-0001 to provide inspection instructions.
Consequently, EASA issued AD 2016-0071 to require a one-time
inspection of the affected motorised fuel valves and, depending on
findings, accomplishment of applicable corrective action(s).
Since that [EASA] AD was issued, new occurrences of fuel leakage
involving the
[[Page 44896]]
affected motorised fuel valves were reported and Airbus D&S issued
Revision 1 of AOT-CN235-28-0001 and Revision 1 of AOT-C295-28-0001
to introduce repetitive inspections and operational checks of the
affected motorised fuel valves.
For the reasons described above, this [EASA] AD retains the
requirements of EASA AD 2016-0071, which is superseded, and
introduces repetitive inspections and operational checks [and
corrective actions, if necessary] of the affected fuel valves.
You may examine the MCAI in the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2016-
9386.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the SNPRM 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:
<bullet> Are consistent with the intent that was proposed in the
SNPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the SNPRM.
Related Service Information Under 1 CFR Part 51
Airbus Defense and Space has issued Alert Operators Transmission
(AOT) AOT-C295-28-0001, Revision 1, dated September 27, 2016; and AOT-
CN235-28-0001, Revision 1, dated September 27, 2016. This service
information describes procedures for repetitive inspections,
replacement of the motorized fuel valves, and operational checks and
corrective actions on affected motorized fuel valves. These documents
are distinct since they apply to different airplane models. 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 14 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection and operational check...... 3 work-hours x $85 per $0 $255 $3,570
hour = $255.
Reporting............................. 1 work-hour x $85 per 0 85 1,190
hour = $85.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary replacements
that will be required based on the results of the required inspection.
We have no way of determining the number of aircraft that might need
these replacements:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per

----------------------------------------------------------------------------------------------------------------
Replacement................................... 5 work-hours x $85 per hour = $38,448 $38,873
$425.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that will enable us to provide
cost estimates for the on-condition corrective actions for the
operational check specified in this AD.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information
Collection Clearance Officer, AES-200.
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 to
the Director of the System Oversight Division.
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.
[[Page 44897]]
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.
