14 CFR Part 39
[Docket No. FAA-2008-0470; Directorate Identifier 2008-CE-026-AD]
RIN 2120-AA64
Airworthiness Directives; APEX Aircraft Model CAP 10 B Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of
the comment period.
-----------------------------------------------------------------------
SUMMARY: We are revising an earlier NPRM for the products listed above.
This proposed AD results from mandatory continuing airworthiness
information (MCAI) originated by an aviation authority of another
country to identify and correct an unsafe condition on an aviation
product. The MCAI describes the unsafe condition as:
An internal review evidenced that the flight controls tie rod
bolts currently installed on the airplane are not in accordance with
the design data. Indeed the bolt shank length has been determined
too short and the material properties of the spacers have been found
inadequate according to the prescribed torque value.
Therefore, bolts' threads could be subject to excessive wear,
which might induce play in flight controls and consequently, induce
vibrations in the control surfaces and reduce the airplane handling.
The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.

Discussion
We proposed to amend 14 CFR part 39 with an earlier NPRM for the
specified products, which was published in the Federal Register on
April 23, 2008 (73 FR 21851). That earlier NPRM proposed to require
actions intended to address the unsafe condition for the products
listed above.
Since that NPRM was issued, we have determined that the
applicability as stated in the NPRM does not include all serial numbers
that could incorporate fibre carbon wing spars as stated in the
applicability of the MCAI.
Relevant Service Information
APEX Aircraft has issued Service Bulletin No. 040206, dated
September 21, 2007. The actions described in this service information
are intended to correct the unsafe condition identified in the MCAI.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
FAA's Determination and Requirements of the Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
Certain changes described above expand the scope of the earlier
NPRM. As a result, we have determined that it is necessary to reopen
the comment period to provide additional opportunity for the public to
comment on the proposed AD.
Differences Between This Proposed AD and the MCAI or Service
Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
[[Page 33739]]
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
We estimate that this proposed AD will affect 31 products of U.S.
registry. We also estimate that it would take about 3 work-hours per
product to comply with the basic requirements of this proposed AD. The
average labor rate is $80 per work-hour. Required parts would cost
about $100 per product.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $10,540, or $340 per product.
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
We 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 this 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); and
3. 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, 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:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
APEX Aircraft: Docket No. FAA-2008-0470; Directorate Identifier
2008-CE-026-AD.
Comments Due Date
(a) We must receive comments by July 14, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the following Model CAP 10 B airplanes,
certificated in any category:
(1) Serial numbers 300 through 317; and
(2) All other serial numbers that incorporate APEX change 000302
(fibre carbon wing spars).
Subject
(d) Air Transport Association of America (ATA) Code 27: Flight
Controls.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
An internal review evidenced that the flight controls tie rod
bolts currently installed on the airplane are not in accordance with
the design data. Indeed the bolt shank length has been determined
too short and the material properties of the spacers have been found
inadequate according to the prescribed torque value.
Therefore, bolts' threads could be subject to excessive wear,
which might induce play in flight controls and consequently, induce
vibrations in the control surfaces and reduce the airplane handling.
To prevent this condition, the present Airworthiness Directive
(AD) mandates replacement of the tie rod bolts and spacers.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Within 50 hours time-in-service after the effective date of
this AD, remove tie rod bolts part number (P/N) 95.56.11.066 and
spacers P/N 11.56.27.038 and replace them with tie rod bolts P/N
95.56.11.418 and spacers P/N 11.56.27.138, following APEX Aircraft
Service Bulletin No. 040206, dated September 21, 2007.
(2) As of the effective date of this AD, do not install any tie
rod bolts P/N 95.56.11.066 or spacers P/N 11.56.27.038.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: No differences.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send
information to ATTN: Sarjapur Nagarajan, Aerospace Engineer, FAA,
Small Airplane Directorate, 901 Locust, Room 301, Kansas City,
Missouri 64106; telephone: (816) 329-4145; fax: (816) 329-4090.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements and has assigned
OMB Control Number 2120-0056.
