SUPPLEMENTARY INFORMATION:
Discussion
We received a report of a fully cracked lower forward carry through
spar cap found on a Textron Aviation Inc. (type certificate previously
held by Cessna Aircraft Company) Model 402C airplane. Investigation
revealed that the crack is a result of metal fatigue. At this time, the
cracking has only been found on the Model 402C airplanes. However, the
carry through spar cap and surrounding structure on the other model
airplanes included in this AD are similar and the loads on the other
model airplanes are similar to (or higher than) the Model 402C
airplanes.
This condition, if not addressed, could cause failure of the carry
through spar cap during flight and result in loss of control. We are
issuing this AD to address the unsafe condition on these products.
Related Service Information Under 1 CFR Part 51
We reviewed Textron Aviation Multi-engine Mandatory Service Letter
MEL-57-01 and Textron Aviation Conquest Mandatory Service Letter CQL-
57-01, both dated December 18, 2017. As applicable, these service
letters describe procedures for repetitively inspecting the forward
lower carry through spar cap for cracks. 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.
Other Related Service Information
We reviewed Textron Aviation Conquest Service Bulletin CQB-57-01,
Textron Aviation Multi-engine Service Bulletin MEB-57-01, and Textron
Multi-engine Service Bulletin MEB-57-02, all dated December 20, 2017.
As applicable, these service bulletins provide the manufacturer's
optional procedures for installing access panels for easier access to
the forward lower carry through spars. This AD does not require
installing the access panels.
FAA's Determination
We are issuing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
AD Requirements
This AD requires repetitively inspecting the left and the right
forward lower carry through spar cap for cracks and replacing the carry
through spar if cracks are found. This AD also requires sending the
inspection results to the FAA.
Interim Action
We consider this AD interim action. Textron Aviation Inc. is
evaluating the initial and repetitive inspection intervals, as well as
designing a replacement lower carry through spar cap from an improved
material. After the evaluations are complete and the design
modification is developed, approved, and available, we may consider
additional rulemaking.
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies waiving notice and comment prior to adoption of this rule
because cracks in the left and/or the right forward lower carry through
spar cap could cause the carry through spar cap to fail during flight
and result in loss of control. Therefore, we find good cause that
notice and opportunity for prior public comment are impracticable. In
addition, for the reason stated above, we find that good cause exists
for making this amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send any written data, views, or
arguments about this final rule. Send your comments to an address
listed under the ADDRESSES section. Include the docket number FAA-2018-
0068 and Product Identifier 2017-CE-049-AD at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this final rule. We will
consider all comments received by the closing date and may amend this
final rule because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this final rule.
Costs of Compliance
We estimate that this AD affects 2,147 airplanes of U.S. registry.
We estimate the following costs to comply with 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 small airplanes, gliders,
balloons, airships, domestic business jet transport airplanes, and
associated appliances to the Director of the Policy and Innovation
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 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.
