SUPPLEMENTARY INFORMATION: I. Objective The objective of this notice is to continue our comprehensive review of regulations governing the System and to eliminate, consistent with law, safety, and soundness, all regulations that are unnecessary, unduly burdensome or costly, or not based on the law. We are requesting public comment to identify FCA regulations that: • May duplicate other requirements; • Are ineffective; or • Impose burdens that are greater than the benefits received. To accomplish our objective, we are targeting particular regulations for a more focused and in-depth review. II. Background The FCA is the independent Federal agency in the executive branch of the Government responsible for examining and regulating System institutions. As a Government-sponsored enterprise, the System primarily provides loans to farmers, ranchers, aquatic producers and harvesters, agricultural cooperatives, and rural utilities. III. Regulations Under Review The regulations of FCA that are subject to regulatory review described in this notice are codified in title 12, chapter VI, of the Code of Federal Regulations. In our previous notices, we asked the public to comment on all of our regulations, and we were able to PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 35361 accomplish our objective of reducing regulatory burden. In this notice, we would like the public to comment specifically on these targeted regulations: (1) Part 607—Assessment and Apportionment of Administrative Expenses; (2) Part 614—Loan Policies and Operations; (3) Part 616—Leasing; (4) Part 617—Borrower Rights; (5) Part 618—General Provisions; and (6) Part 626—Nondiscrimination in Lending. IV. Requesting Comments Your comments are appreciated and will assist us in our continuing efforts to identify and reduce regulatory burden on System institutions. We will also continue our efforts to maintain and adopt regulations and policies that are necessary to implement the Farm Credit Act of 1971, as amended, and ensure the safety and soundness of the System. These actions will enable the System to better serve America’s farmers, ranchers, aquatic producers and harvesters, agricultural cooperatives, and rural utilities in changing agricultural credit markets.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No. 2008– 0086, dated May 13, 2008 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: The original designed bellcrank for the aileron control system in the wing needed to be installed with slightly bent rod ends during production of the aircraft to avoid friction and possible chafing. In addition to being a nonpreferable production practice, this creates the risk of replacement parts being installed during subsequent in-service maintenance without being bent or not being bent correctly. This condition, if not detected and corrected, could lead to chafing damage of the aileron control system and consequent loss of control of the aircraft. Diamond Aircraft Industries GmbH has now developed a new aileron bellcrank that allows for additional angular movement of the push rod, thereby eliminating the chafing risk without using bent rod ends. For the reasons described above, this EASA Airworthiness Directive (AD) requires the replacement of the aileron bellcrank with an improved part and the replacement of any bent rod ends P/N DAI–9027–00–01. In addition, this AD prohibits the reinstallation of P/N DA4–2717–50–00 aileron bellcranks and bent rod ends P/N DAI–9027–00–01 as replacement in the future. Relevant Service Information Diamond Aircraft Industries GmbH has issued Mandatory Service Bulletin No. MSB–42–043/1, dated April 3, 2008; Diamond Aircraft Industries GmbH Work Instruction WI–MSB–42–043, dated February 4, 2008; and Diamond Aircraft Industries GmbH Drawing Number D60–2717–00–00, dated January 24, 2008. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. 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 PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 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. 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 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 156 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 (no labor cost; 3 work-hours warranty given by manufacturer). Required parts would cost $0 (warranty credit given by manufacturer) per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $0, or $0 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 E:\FR\FM\23JNP1.SGM 23JNP1 Federal Register / Vol. 73, No. 121 / Monday, June 23, 2008 / Proposed Rules 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. § 39.13 [Amended] yshivers on PROD1PC62 with PROPOSALS Diamond Aircraft Industries GmbH: Docket No. FAA–2008–0685; Directorate Identifier 2008–CE–037–AD.

Reason (e) The mandatory continuing airworthiness information (MCAI) states: The original designed bellcrank for the aileron control system in the wing needed to be installed with slightly bent rod ends during production of the aircraft to avoid friction and possible chafing. In addition to being a nonpreferable production practice, this creates the risk of replacement parts being installed during subsequent in-service maintenance without being bent or not being bent correctly. This condition, if not detected and corrected, could lead to chafing damage of the aileron control system and consequent loss of control of the aircraft. Diamond Aircraft Industries GmbH has now developed a new aileron bellcrank that allows for additional angular movement of the push rod, thereby eliminating the chafing risk without using bent rod ends. For the reasons described above, this EASA Airworthiness Directive (AD) requires the replacement of the aileron bellcrank with an improved part and the replacement of any bent rod ends P/N DAI–9027–00–01. In addition, this AD prohibits the reinstallation of P/N DA4–2717–50–00 aileron bellcranks and bent rod ends P/N DAI–9027–00–01 as replacement in the future. Actions and Compliance (f) Unless already done, do the following actions: (1) Within the next 200 hours time-inservice (TIS) after the effective date of this AD, replace the aileron bellcrank, P/N DA4– 2717–50–00, with the improved design aileron bellcrank, P/N DA4–2717–50–00_01, and replace any bent rod ends, P/N DAI– 9027–00–01, with straight rod ends, P/N DAI–9027–00–01, following Mandatory Service Bulletin No. MSB–42–043/1, dated April 3, 2008; Diamond Aircraft Industries GmbH Work Instruction WI–MSB–42–043, dated February 4, 2008; and Diamond Aircraft Industries GmbH Drawing Number D60–2717–00–00, dated January 24, 2008. (2) As of the effective date of this AD, do not install any aileron bellcrank, P/N DA4– 2717–50–00, or bent rod ends, P/N DAI– 9027–00–01. FAA AD Differences 2.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No. 2008-0086, dated May 13, 2008 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    The original designed bellcrank for the aileron control system 
in the wing needed to be installed with slightly bent rod ends 
during production of the aircraft to avoid friction and possible 
chafing. In addition to being a nonpreferable production practice, 
this creates the risk of replacement parts being installed during 
subsequent in-service maintenance without being bent or not being 
bent correctly. This condition, if not detected and corrected, could 
lead to chafing damage of the aileron control system and consequent 
loss of control of the aircraft. Diamond Aircraft Industries GmbH 
has now developed a new aileron bellcrank that allows for additional 
angular movement of the push rod, thereby eliminating the chafing 
risk without using bent rod ends.
    For the reasons described above, this EASA Airworthiness 
Directive (AD) requires the replacement of the aileron bellcrank 
with an improved part and the replacement of any bent rod ends P/N 
DAI-9027-00-01. In addition, this AD prohibits the reinstallation of 
P/N DA4-2717-50-00 aileron bellcranks and bent rod ends P/N DAI-
9027-00-01 as replacement in the future.

Relevant Service Information

    Diamond Aircraft Industries GmbH has issued Mandatory Service 
Bulletin No. MSB-42-043/1, dated April 3, 2008; Diamond Aircraft 
Industries GmbH Work Instruction WI-MSB-42-043, dated February 4, 2008; 
and Diamond Aircraft Industries GmbH Drawing Number D60-2717-00-00, 
dated January 24, 2008. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

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.

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 
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 156 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 (no labor cost; 3 work-hours 
warranty given by manufacturer). Required parts would cost $0 (warranty 
credit given by manufacturer) per product. Where the service 
information lists required parts costs that are covered under warranty, 
we have assumed that there will be no charge for these costs. As we do 
not control warranty coverage for affected parties, some parties may 
incur costs higher than estimated here.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $0, or $0 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

[[Page 35363]]

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

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:

Diamond Aircraft Industries GmbH: Docket No. FAA-2008-0685; 
Directorate Identifier 2008-CE-037-AD.

Comments Due Date

    (a) We must receive comments by July 23, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Model DA 42 airplanes, all serial 
numbers, with aileron bellcranks part number (P/N) DA4-2717-50-00 
installed, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 27: Flight 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    The original designed bellcrank for the aileron control system 
in the wing needed to be installed with slightly bent rod ends 
during production of the aircraft to avoid friction and possible 
chafing. In addition to being a nonpreferable production practice, 
this creates the risk of replacement parts being installed during 
subsequent in-service maintenance without being bent or not being 
bent correctly. This condition, if not detected and corrected, could 
lead to chafing damage of the aileron control system and consequent 
loss of control of the aircraft. Diamond Aircraft Industries GmbH 
has now developed a new aileron bellcrank that allows for additional 
angular movement of the push rod, thereby eliminating the chafing 
risk without using bent rod ends.
    For the reasons described above, this EASA Airworthiness 
Directive (AD) requires the replacement of the aileron bellcrank 
with an improved part and the replacement of any bent rod ends P/N 
DAI-9027-00-01. In addition, this AD prohibits the reinstallation of 
P/N DA4-2717-50-00 aileron bellcranks and bent rod ends P/N DAI-
9027-00-01 as replacement in the future.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within the next 200 hours time-in-service (TIS) after the 
effective date of this AD, replace the aileron bellcrank, P/N DA4-
2717-50-00, with the improved design aileron bellcrank, P/N DA4-
2717-50-00--01, and replace any bent rod ends, P/N DAI-9027-00-01, 
with straight rod ends, P/N DAI-9027-00-01, following Mandatory 
Service Bulletin No. MSB-42-043/1, dated April 3, 2008; Diamond 
Aircraft Industries GmbH Work Instruction WI-MSB-42-043, dated 
February 4, 2008; and Diamond Aircraft Industries GmbH Drawing 
Number D60-2717-00-00, dated January 24, 2008.
    (2) As of the effective date of this AD, do not install any 
aileron bellcrank, P/N DA4-2717-50-00, or bent rod ends, P/N DAI-
9027-00-01.

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.
