[Docket No. FAA-2018-0003; Directorate Identifier 2017-CE-033-AD]
RIN 2120-AA64
Airworthiness Directives; American Champion Aircraft Corp.
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede Airworthiness Directive (AD) 2017-07-
10, which applies to certain American Champion Aircraft Corp. (ACAC)
Model 8KCAB airplanes. AD 2017-07-10 requires fabrication and
installation of a placard to prohibit aerobatic flight, inspection of
the aileron hinge rib and support, and a reporting requirement of the
inspection results to the FAA. This AD was prompted by a report of a
cracked hinge support and cracked hinge ribs, which resulted in partial
loss of control with the aileron binding against the cove. Since we
issued AD 2017-07-10, ACAC redesigned the aileron hinge supports with a
reinforcement kit to strengthen the supports and prevent future damage
from developing. This proposed AD would require repetitive inspections
of the aileron hinge support, installation of the aileron hinge support
reinforcement kit, and incorporation of revised pages into the service
manual. We are proposing this AD to address the unsafe condition on
these products.
DATES: We must receive comments on this proposed AD by February 26,
2018.

Discussion
We issued AD 2017-07-10, Amendment 39-18849 (82 FR 17542, April 12,
2017), (``AD 2017-07-10''), for certain American Champion Aircraft
Corp. (ACAC) Model 8KCAB airplanes. AD 2017-07-10 requires fabrication
and installation of a placard to prohibit aerobatic flight, inspection
of the aileron hinge rib and support, and a reporting requirement of
the inspection results to the FAA. AD 2017-07-10 resulted from a report
of a cracked hinge support and cracked hinge ribs, which resulted in
partial loss of control with the aileron binding against the cove. We
issued AD 2017-07-10 to prevent failure of the aileron support
structure, which may lead to excessive deflection, binding of the
control surface, and potential loss of control.
Actions Since AD 2017-07-10 Was Issued
Since we issued AD 2017-10, ACAC redesigned the aileron hinge
supports with a reinforcement kit. This kit, when incorporated,
strengthens the supports and prevents future damage from developing.
Related Service Information Under 1 CFR Part 51
We reviewed American Champion Aircraft Corp. Service Letter (SL)
442, Revision A, dated August 18, 2017 (ACAC SL No. 442); American
Champion Aircraft Corp. Service Letter 444 Initial Revision, dated
August 18, 2017 (ACAC SL No. 444); and page 4-1 of the Airworthiness
Limitations section and page 5-9 of the Time and Maintenance Checks,
both dated October 3, 2017, and included in American Champion Aircraft
Corporation SM-601 8KCAB Service Manual, Reissue B, dated October 3,
2017. ACAC SL No. 442 describes procedures and inspection intervals for
inspection of the aileron hinge rib and hinge support. ACAC SL No. 444
provides instructions for the installation of the aileron hinge
reinforcement kit.
[[Page 1312]]
Page 4-1 and page 5-9 are revised pages that add a repetitive
inspection to the 8KCAB Service Manual, SM-601, Reissue B, dated
October 3, 2017. 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
We are proposing 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.
Proposed AD Requirements
This proposed AD would retain the placarding requirement of AD
2017-07-10 to prohibit aerobatic flight until completion of the initial
10-hour inspection. This proposed AD would also require repetitive 100-
hour inspections until a maximum of 400 hours is reached, installation
of the aileron hinge reinforcement kit, and incorporation of pages into
the Airworthiness Limitations and Time and Maintenance Checks sections
of the service manual. The existing AD contained a reporting
requirement for the inspection results. This proposed NPRM will not
include a reporting requirement.
Provided no damage is found during the inspections, an airplane
could have up to five inspections before incorporating the
reinforcement kit (initially at 10 hours TIS with the retained
inspection from AD 2017-07-10, and then four 100-hour inspections up to
a maximum of 400 hours TIS).
Differences Between This Proposed AD and the Service Information
ACAC SL No. 442 and ACAC SL No. 444 both require installation of
the aileron hinge support reinforcement kit within 100 hours TIS for
airplanes used for competitive aerobatics. Since the FAA has no way of
tracking airplanes used for competitive aerobatics, we require
installation of the reinforcement kit within 400 hours TIS. ACAC SL No.
444 requires 100-hour repetitive inspections after installation of the
reinforcement kit. This proposed AD does not write those actions into
the AD requirements; however, the revised pages of the Airworthiness
Limitations section in the service manual include that inspection
requirement. Both ACAC SL No. 442 and ACAC SL No. 444 have reporting
requirements, but this AD does not include a reporting requirement. The
actions of this AD take precedence over the service information.
Costs of Compliance
We estimate that this proposed AD affects 64 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Fabrication of placard, inspection of 2 work-hours x $85 per $100 $270.00 $17,280
aileron hinge rib and support. hour = $170.00.
Repetitive 100-hour TIS inspections... 1.5 work-hours x $85 per N/A 127.50 8,160
hour = $127.50.
Installation of aileron hinge support 50 work-hours x $85 per 2,200 6,450 412,800
reinforcement kit. hour = $4,250.
----------------------------------------------------------------------------------------------------------------
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, domestic
business jet transport airplanes, and associated appliances to the
Director of the Policy and Innovation Division.
Regulatory Findings
We have 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 that the 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

the aileron hinge rib and support for cracks or other damage
following American Champion Aircraft Corporation Service Letter (SL)
442, dated February 16, 2017, or American Champion Aircraft Corp.
Service Letter (SL) 442, Revision A, dated August 18, 2017 (ACAC SL
No. 442).
(2) If no cracks or other damage is found during the initial
inspection required in paragraph (h)(1) of this AD, the placard
prohibiting aerobatic flight required in paragraph (g)(2) of this AD
can be removed.
(3) Within 100 hours TIS from the initial inspection required in
paragraph (h)(1) of this AD or within 10 hours TIS after the
effective date of this AD, whichever occurs later, and repetitively
thereafter at intervals not the exceed 100 hours TIS, inspect the
aileron hinge rib and support for cracks or other damage following
ACAC SL No. 442.
(4) If cracks or other damage is found during any inspection
required in paragraph (h)(1) or (3) of this AD, before further
flight, replace any retained parts or structure that are cracked or
damaged, and install the aileron hinge reinforcement kit following
American Champion Aircraft Corp. Service Letter 444, dated August
