ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of the comment period. AGENCY: 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: SUMMARY: pwalker on PROD1PC71 with PROPOSALS 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. DATES: We must receive comments on this proposed AD by July 14, 2008.

Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2008–0470; Directorate Identifier 2008–CE–026–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We proposed to amend 14 CFR part 39 with an earlier NPRM for the specified products, which was PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 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 E:\FR\FM\13JNP1.SGM 13JNP1 Federal Register / Vol. 73, No. 115 / Friday, June 13, 2008 / Proposed Rules 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. pwalker on PROD1PC71 with PROPOSALS 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, VerDate Aug<31>2005 16:17 Jun 12, 2008 Jkt 214001 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. 33739 (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.

[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.

DATES: We must receive comments on this proposed AD by July 14, 2008.

ADDRESSES: You may send comments by any of the following methods:

SUPPLEMENTARY INFORMATION:

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2008-0470; 
Directorate Identifier 2008-CE-026-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We

receive about this proposed AD.

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.
