[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

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:

unless already done.

(g) Restrict Airplane Operation

    (1) As of April 12, 2017 (the effective date retained from AD 
2017-07-10), the airplane is restricted to non-aerobatic flight 
until the actions required in paragraphs (g)(2) through (3) of this 
AD are done.
    (2) Before further flight after April 12, 2017 (the effective 
date retained from AD 2017-07-10), fabricate a placard using at 
least \1/8\ inch letters with the words ``AEROBATIC FLIGHT 
PROHIBITED'' on it and install the placard on the instrument panel 
within the pilot's clear view.
    (3) This action may be performed by the owner/operator (pilot) 
holding at least a private pilot certificate and must be entered 
into the aircraft records showing compliance with this AD in

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 
18, 2017 (ACAC SL No. 444).
    (5) Within 400 hours after the initial inspection required in 
paragraph (h)(1) of this AD, if not already done as required in 
paragraph (h)(4) of this AD, install the aileron hinge reinforcement 
kit following the procedures in ACAC SL No. 444.
    (6) After installation of the aileron hinge reinforcement kit 
required in paragraph (h)(4) or (5) of this AD, as applicable,
