KG Model S10-VT Powered Sailplanes AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above that will supersede an existing AD. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: cprice-sewell on PROD1PC72 with RULES AD 2007–0315–E was issued to address a possible fuel leakage in the gear compartment in front of the engine and mandated inspections and replacement of fuel plasticmade connectors by connectors made of metal. Since its publication, another fuel leakage has been reported on a S10-VT which had implemented the STEMME Service Bulletin (SB) A31–10–082 as required by AD 2007–0315–E. It has been determined that the fuel leak may have been caused by the deformation that the originally installed clamps created on the fuel hoses and thus preventing the new clamps from being sufficiently pinched to perform a correct tightening. This AD requires actions that are intended to address the unsafe condition described in the MCAI. DATES: This AD becomes effective June 23, 2008. On June 23, 2008, the Director of the Federal Register approved the incorporation by reference of STEMME F & D Service Bulletin A31–10–083, Am-Index: 01.a, dated February 26, 2008, listed in this AD. As of February 20, 2008 (73 FR 5733, January 31, 2008), the Director of the Federal Register approved the incorporation by reference of STEMME F & D Service Bulletin A31–10–082, AM.-Index: 01.a, dated November 30, 2007, listed in this AD. We must receive comments on this AD by July 2, 2008.

SUPPLEMENTARY INFORMATION: Discussion On January 24, 2008, we issued AD 2008–03–06, Amendment 39–15355 (73 FR 5733, January 31, 2008). That AD required actions intended to address an unsafe condition on the products listed above. Since we issued AD 2008–03–06, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued Emergency AD No. 2008–0053–E, dated March 5, 2008 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: AD 2007–0315–E was issued to address a possible fuel leakage in the gear compartment in front of the engine and mandated inspections and replacement of fuel plasticmade connectors by connectors made of metal. Since its publication, another fuel leakage has been reported on a S10-VT which had implemented the STEMME Service Bulletin (SB) A31–10–082 as required by AD 2007–0315–E.

Relevant Service Information FAA’s Determination and Requirements of the 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 issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This AD is considered an interim action because we are not including a mandatory requirement to replace STEMME part number (P/N) M476 single-ear clamps in the fuel system with P/N 10M–181 single-ear clamps on all affected sailplanes unless a leak in the fuel system is found. The Administrative Procedure Act does not permit the FAA to ‘‘bootstrap’’ a longterm requirement into an urgent safety of flight action where the rule becomes effective at the same time the public has the opportunity to comment. The shortterm action and the long-term action are analyzed separately for justification to bypass prior public notice. After issuing this AD, we may initiate further AD action (notice of proposed rulemaking followed by a final rule) to require replacing all P/N M476 singleear clamps in the fuel system with P/N 10M–181 single-ear clamps on all affected sailplanes by a specified time. Credit will be given in any subsequent action for the replacement done under this AD. E:\VIC\02JNR1.LOC 02JNR1 31356 Federal Register / Vol. 73, No. 106 / Monday, June 2, 2008 / Rules and Regulations 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. FAA’s 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 a leak in the area of the fuel line was found, which could result in the possibility of fuel leaking into the engine compartment. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. cprice-sewell on PROD1PC72 with RULES Differences Between This 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 have also required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the AD. These requirements take precedence over those copied from the MCAI. Regulatory Findings We determined that 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); 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 AD and placed it in the AD docket. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2008–0598; Directorate Identifier 2008–CE–031– 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 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 AD. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, VerDate Aug 31 2005 10:44 Aug 13, 2008 Jkt 214001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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] 2. The FAA amends § 39.13 by removing Amendment 39–15355 (73 FR 5733, January 31, 2008), and adding the following new AD: ■ PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 2008–11–20 Stemme GmbH & Co. KG: Amendment 39–15543; Docket No. FAA–2008–0598; Directorate Identifier 2008–CE–031–AD. Effective Date (a) This airworthiness directive (AD) becomes effective June 23, 2008. Affected ADs (b) This AD supersedes AD 2008–03–06; Amendment 39–15355. Applicability (c) This AD applies to Model S10–VT powered sailplanes, serial numbers 11–001 through 11–112, certificated in any category. Subject (d) Air Transport Association of America (ATA) Code 28: Fuel. Reason (e) The mandatory continuing airworthiness information (MCAI) states: AD 2007–0315–E was issued to address a possible fuel leakage in the gear compartment in front of the engine and mandated inspections and replacement of fuel plasticmade connectors by connectors made of metal. Since its publication, another fuel leakage has been reported on a S10–VT which had implemented the STEMME Service Bulletin (SB) A31–10–082 as required by AD 2007–0315–E. It has been determined that the fuel leak may have been caused by the deformation that the originally installed clamps created on the fuel hoses and thus preventing the new clamps from being sufficiently pinched to perform a correct tightening. The present Airworthiness Directive (AD) supersedes AD 2007–0315–E and requires you to check the fuel system according to the STEMME SB A31–10–083 as well as to replace single-ear clamps and plastic connectors. The actions specified by this AD are intended to reduce the potential for a fire to ignite and which could lead to loss of control of the sailplane. Actions and Compliance (f) Unless already done, do the following actions: (1) For all sailplanes affected by this AD, except for serial numbers 11–036, 11–067, 11–068, and 11–090: Before further flight after March 21, 2008 (the compliance date retained from AD 2008–03–06), replace all plastic T- and Y-connectors in the fuel system with metal connectors. Do the replacements following STEMME F & D Service Bulletin A31–10–082, AM.—Index: 01.a, dated November 30, 2007. Note: Serial numbers 11–036, 11–067, 11– 068, and 11–090 had the plastic T- and Yconnectors in the fuel system replaced with metal connectors by the manufacturer. (2) For all sailplanes affected by this AD: Before further flight after June 23, 2008 (the effective date of this AD), inspect the fuel system for possible leakage. Do the inspection following STEMME F & D Service Bulletin A31–10–083, Am-Index: 01.a, dated February 26, 2008. E:\VIC\02JNR1.LOC 02JNR1 Federal Register / Vol. 73, No. 106 / Monday, June 2, 2008 / Rules and Regulations (3) For all sailplanes affected by this AD: If any leak is found during the inspection required in paragraph (f)(2) of this AD, before further flight, repair the leak following an FAA-approved repair procedure and replace all STEMME part number (P/N) M476 singleear clamps in the fuel system with P/N 10M– 181 single-ear clamps. Do the replacements following STEMME F & D Service Bulletin A31–10–083, Am-Index: 01.a, dated February 26, 2008. (4) After June 23, 2008 (the effective date of this AD), do not install plastic ‘‘T’’ and ‘‘Y’’ shape connectors and P/N M476 singleear clamps in the fuel system. FAA AD Differences cprice-sewell on PROD1PC72 with RULES Note: This AD differs from the MCAI and/ or service information as follows: (1) The MCAI and the service information require replacing all P/N M476 single-ear clamps in the fuel system with P/N 10M–181 single-ear clamps within the next 12 months after the effective date. (2) This AD is considered an interim action because we are not including a mandatory requirement to replace all STEMME P/N M476 single-ear clamps in the fuel system with P/N 10M–181 single-ear clamps on all affected sailplanes unless a leak in the fuel system is found. The Administrative Procedure Act does not permit the FAA to ‘‘bootstrap’’ a long-term requirement into an urgent safety of flight action where the rule becomes effective at the same time the public has the opportunity to comment. The shortterm action and the long-term action are analyzed separately for justification to bypass prior public notice. (3) After issuing this AD, we may initiate further AD action (notice of proposed rulemaking followed by a final rule) to require replacing all P/N M476 single-ear clamps in the fuel system with P/N 10M–181 single-ear clamps on all affected sailplanes by a specified time. Credit will be given in any subsequent action for the replacement done under this AD. 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: Greg Davison, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329–4130; fax: (816) 329– 409. Before using any approved AMOC on any sailplane 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. VerDate Aug 31 2005 10:44 Aug 13, 2008 Jkt 214001 (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. 31357 ACTION: Final rule; technical amendment.

Airworthiness Directives; Stemme GmbH & Co. KG Model S10-VT 
Powered Sailplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above that will supersede an existing AD. This AD 
results from mandatory continuing airworthiness information (MCAI) 
issued by the aviation authority of another country to identify and 
correct an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as:

    AD 2007-0315-E was issued to address a possible fuel leakage in 
the gear compartment in front of the engine and mandated inspections 
and replacement of fuel plastic-made connectors by connectors made 
of metal. Since its publication, another fuel leakage has been 
reported on a S10-VT which had implemented the STEMME Service 
Bulletin (SB) A31-10-082 as required by AD 2007-0315-E.
    It has been determined that the fuel leak may have been caused 
by the deformation that the originally installed clamps created on 
the fuel hoses and thus preventing the new clamps from being 
sufficiently pinched to perform a correct tightening.

    This AD requires actions that are intended to address the unsafe 
condition described in the MCAI.

DATES: This AD becomes effective June 23, 2008.
    On June 23, 2008, the Director of the Federal Register approved the 
incorporation by reference of STEMME F & D Service Bulletin A31-10-083, 
Am-Index: 01.a, dated February 26, 2008, listed in this AD.
    As of February 20, 2008 (73 FR 5733, January 31, 2008), the 
Director of the Federal Register approved the incorporation by 
reference of STEMME F & D Service Bulletin A31-10-082, AM.-Index: 01.a, 
dated November 30, 2007, listed in this AD.
    We must receive comments on this AD by July 2, 2008.

SUPPLEMENTARY INFORMATION:

Discussion

    On January 24, 2008, we issued AD 2008-03-06, Amendment 39-15355 
(73 FR 5733, January 31, 2008). That AD required actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 2008-03-06, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, has issued Emergency AD No. 2008-0053-E, dated 
March 5, 2008 (referred to after this as ``the MCAI''), to correct an 
unsafe condition for the specified products. The MCAI states:

    AD 2007-0315-E was issued to address a possible fuel leakage in 
the gear compartment in front of the engine and mandated inspections 
and replacement of fuel plastic-made connectors by connectors made 
of metal. Since its publication, another fuel leakage has been 
reported on a S10-VT which had implemented the STEMME Service 
Bulletin (SB) A31-10-082 as required by AD 2007-0315-E.
    It has been determined that the fuel leak may have been caused 
by the deformation that the originally installed clamps created on 
the fuel hoses and thus preventing the new clamps from being 
sufficiently pinched to perform a correct tightening.
    The present Airworthiness Directive (AD) supersedes AD 2007-
0315-E and requires you to check the fuel system according to the 
STEMME SB A31-10-083 as well as to replace single-ear clamps and 
plastic connectors.
    The actions specified by this AD are intended to reduce the 
potential for a fire to ignite and which could lead to loss of 
control of the sailplane.

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    STEMME F & D has issued Service Bulletin A31-10-083, Am-Index: 
01.a, dated February 26, 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 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 issuing this AD because we 
evaluated all information provided by the State of Design Authority and 
determined the unsafe condition exists and is likely to exist or 
develop on other products of the same type design.
    This AD is considered an interim action because we are not 
including a mandatory requirement to replace STEMME part number (P/N) 
M476 single-ear clamps in the fuel system with P/N 10M-181 single-ear 
clamps on all affected sailplanes unless a leak in the fuel system is 
found. The Administrative Procedure Act does not permit the FAA to 
``bootstrap'' a long-term requirement into an urgent safety of flight 
action where the rule becomes effective at the same time the public has 
the opportunity to comment. The short-term action and the long-term 
action are analyzed separately for justification to bypass prior public 
notice.
    After issuing this AD, we may initiate further AD action (notice of 
proposed rulemaking followed by a final rule) to require replacing all 
P/N M476 single-ear clamps in the fuel system with P/N 10M-181 single-
ear clamps on all affected sailplanes by a specified time. Credit will 
be given in any subsequent action for the replacement done under this 
AD.

Differences Between This 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 have also required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the AD. These requirements take 
precedence over those copied from the MCAI.

FAA's 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 a 
leak in the area of the fuel line was found, which could result in the 
possibility of fuel leaking into the engine compartment. Therefore, we 
determined that notice and opportunity for public comment before 
issuing this AD are impracticable and that good cause exists for making 
this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2008-0598; Directorate 
Identifier 2008-CE-031-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 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 AD.

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 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); 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 AD and placed it in the AD docket.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by removing Amendment 39-15355 (73 FR 
5733, January 31, 2008), and adding the following new AD:

2008-11-20 Stemme GmbH & Co. KG: Amendment 39-15543; Docket No. FAA-
2008-0598; Directorate Identifier 2008-CE-031-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective June 23, 
2008.

Affected ADs

    (b) This AD supersedes AD 2008-03-06; Amendment 39-15355.

Applicability

    (c) This AD applies to Model S10-VT powered sailplanes, serial 
numbers 11-001 through 11-112, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 28: Fuel.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    AD 2007-0315-E was issued to address a possible fuel leakage in 
the gear compartment in front of the engine and mandated inspections 
and replacement of fuel plastic-made connectors by connectors made 
of metal. Since its publication, another fuel leakage has been 
reported on a S10-VT which had implemented the STEMME Service 
Bulletin (SB) A31-10-082 as required by AD 2007-0315-E.
    It has been determined that the fuel leak may have been caused 
by the deformation that the originally installed clamps created on 
the fuel hoses and thus preventing the new clamps from being 
sufficiently pinched to perform a correct tightening.
    The present Airworthiness Directive (AD) supersedes AD 2007-
0315-E and requires you to check the fuel system according to the 
STEMME SB A31-10-083 as well as to replace single-ear clamps and 
plastic connectors.
    The actions specified by this AD are intended to reduce the 
potential for a fire to ignite and which could lead to loss of 
control of the sailplane.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) For all sailplanes affected by this AD, except for serial 
numbers 11-036, 11-067, 11-068, and 11-090: Before further flight 
after March 21, 2008 (the compliance date retained from AD 2008-03-
06), replace all plastic T- and Y-connectors in the fuel system with 
metal connectors. Do the replacements following STEMME F & D Service 
Bulletin A31-10-082, AM.--Index: 01.a, dated November 30, 2007.

    Note: Serial numbers 11-036, 11-067, 11-068, and 11-090 had the 
plastic T- and Y-connectors in the fuel system replaced with metal 
connectors by the manufacturer.

    (2) For all sailplanes affected by this AD: Before further 
flight after June 23, 2008 (the effective date of this AD), inspect 
the fuel system for possible leakage. Do the inspection following 
STEMME F & D Service Bulletin A31-10-083, Am-Index: 01.a, dated 
February 26, 2008.

[[Page 31357]]

    (3) For all sailplanes affected by this AD: If any leak is found 
during the inspection required in paragraph (f)(2) of this AD, 
before further flight, repair the leak following an FAA-approved 
repair procedure and replace all STEMME part number (P/N) M476 
single-ear clamps in the fuel system with P/N 10M-181 single-ear 
clamps. Do the replacements following STEMME F & D Service Bulletin 
A31-10-083, Am-Index: 01.a, dated February 26, 2008.
    (4) After June 23, 2008 (the effective date of this AD), do not 
install plastic ``T'' and ``Y'' shape connectors and P/N M476 
single-ear clamps in the fuel system.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows:
    (1) The MCAI and the service information require replacing all 
P/N M476 single-ear clamps in the fuel system with P/N 10M-181 
single-ear clamps within the next 12 months after the effective 
date.
    (2) This AD is considered an interim action because we are not 
including a mandatory requirement to replace all STEMME P/N M476 
single-ear clamps in the fuel system with P/N 10M-181 single-ear 
clamps on all affected sailplanes unless a leak in the fuel system 
is found. The Administrative Procedure Act does not permit the FAA 
to ``bootstrap'' a long-term requirement into an urgent safety of 
flight action where the rule becomes effective at the same time the 
public has the opportunity to comment. The short-term action and the 
long-term action are analyzed separately for justification to bypass 
prior public notice.
    (3) After issuing this AD, we may initiate further AD action 
(notice of proposed rulemaking followed by a final rule) to require 
replacing all P/N M476 single-ear clamps in the fuel system with P/N 
10M-181 single-ear clamps on all affected sailplanes by a specified 
time. Credit will be given in any subsequent action for the 
replacement done under this AD.

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: Greg Davison, Aerospace Engineer, FAA, Small 
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 
64106; telephone: (816) 329-4130; fax: (816) 329-409. Before using 
any approved AMOC on any sailplane 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.
