Airworthiness Directives; American Champion Aircraft Corp.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

––––––––––––––––––––––––––––––––––

SUMMARY: We are adopting a new airworthiness directive (AD) for certain American Champion
Aircraft Corp. Model 8KCAB airplanes. This AD 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. We are issuing this AD to correct the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Discussion

     We received a report of an event on an American Champion Aircraft Corp. Model 8KCAB
airplane. In this event the pilot reported a stuck aileron during some phases of flight. The pilot was
able to “un-stick” the aileron and land the airplane. Upon inspection, the operator found cracked
structure around several of the aileron hinges. 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. This condition, if not corrected, could result in failure of the aileron support
structure; leading to excessive deflection, binding of the control surface, and potential loss of control.
We are issuing this AD to correct the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

     We reviewed American Champion Aircraft Corp. Service Letter 442, dated February 16, 2017.
The service information describes procedures for initial and repetitive inspections of the aileron hinge
rib and support. 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.

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 accomplishing the actions specified in the service information described
previously, except as discussed under “Differences Between the AD and the Service Information.”
This AD also requires sending the inspection results to the FAA so that appropriate FAA-approved
repair action can be incorporated and the information can be evaluated for any possible future
inspections or modifications.



                                                    2
1065

Differences Between the AD and the Service Information

     American Champion Aircraft Corp. Service Letter (SL) 442, dated February 16, 2017, requires
repetitive inspections. The FAA has not determined whether these intervals are appropriate. This AD
includes fabrication and installation of a placard limiting aerobatic flight for the 10 flight hours
allowed prior to the inspection. The service information does not contain such a placard limitation.
The service information requires reporting inspection results to American Champion. This AD
requires reporting of inspection results to the FAA. The service information does not address
corrective actions if cracks are found. This AD will not allow further flight for airplanes with known
cracks. The actions required by this AD take precedence over the service information.

FAA's Justification and Determination of the Effective Date

     An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found
that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule
because these cracks can lead to a loss of control and current evidence suggests they are growing
rapidly. Therefore, we find that notice and opportunity for prior public comment are impracticable
and 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 AD. Send your comments to an address listed under the ADDRESSES
section. Include the docket number FAA-2017-0283 and Directorate Identifier 2017-CE-009-AD at
the beginning of your comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this AD. We will consider all comments received by
the closing date and may amend this AD 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 AD.

Costs of Compliance

    We estimate that this AD affects 64 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                            Estimated Costs

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

                                                   3
1066

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.

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.

2017-07-10 American Champion Aircraft Corp.: Amendment 39-18849; Docket No. FAA-2017-
0283; Directorate Identifier 2017-CE-009-AD.

(a) Effective Date

    This AD is effective April 12, 2017.

(b) Affected ADs

    None.

(c) Applicability

     This AD applies to the following American Champion Aircraft Corp. Model 8KCAB airplanes
that are certificated in any category:
     (i) Serial numbers 1116-2012 through 1120-2012, and 1122-2012 and up; and
     (ii) any Model 8KCAB airplane equipped with part number 4-2142 exposed balance ailerons.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association (ATA) of America Code
57, Wings.

(e) Unsafe Condition

     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. We are issuing this AD to
prevent failure of the aileron support structure, which may lead to excessive deflection, binding of the
control surface, and potential loss of control.

(f) Compliance

    Comply with this AD within the compliance times specified, unless already done.

(g) Restrict Airplane Operation

     As of April 12, 2017 (the effective date of this AD), the airplane is restricted to non-aerobatic
flight until the actions required in paragraphs (h)(1) through (3) of this AD are done, as applicable.
This restriction is done as follows:
     (1) Before further flight after April 12, 2017 (the effective date of this AD), 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.
     (2) 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


                                                    5
1068

accordance with 14 CFR 43.9 (a)(1)-(4) and 14 CFR 91.417(a)(2)(v). The record must be maintained
as required by 14 CFR 91.417, 121.380, or 135.439.

(h) Inspection

     (1) Within the next 10 hours time-in-service (TIS) after April 12, 2017 (the effective date of this
AD), inspect the aileron hinge rib and support following American Champion Aircraft Corporation
Service Letter (SL) 442, dated February 16, 2017.
     (2) If no cracks are found, during the inspection required in paragraph (h)(1) of this AD, the
placard prohibiting aerobatic flight required in paragraph (g)(1) of this AD can be removed.
     (3) If cracks are found during the inspection required in paragraph (h)(1) of this AD, no further
flight is permitted until an FAA-approved repair for this AD has been accomplished. There is
currently no fix for airplanes with cracks in this area so such airplanes could not be operated until a
repair that was FAA-approved specifically for the AD is incorporated.
     (4) Within 10 days after the inspection required in paragraph (h)(1) of this AD or within 10 days
after April 12, 2017 (the effective date of this AD), whichever occurs later, report the inspection
results to the FAA at the Chicago Aircraft Certification Office (ACO). Submit the report to the FAA
using the contact information found in paragraph (j) of this AD. Include in the report the following
information:
     (i) Hours TIS on the airplane since the affected part was installed,
     (ii) crack length, and
     (iii) location for all cracks found.

(i) Paperwork Reduction Act Burden Statement

     A federal agency may not conduct or sponsor, and a person is not required to respond to, nor
shall a person be subject to a 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 OMB Control Number for this information collection is
2120-0056. Public reporting for this collection of information is estimated to be approximately 5
