SUPPLEMENTARY INFORMATION: Streamlined Issuance of AD The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. This streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products. This proposed AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The proposed AD contains text copied from the MCAI and for this reason might not follow our plain language principles. 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–2007–27109; Directorate Identifier 2007–CE–005–AD’’ at the beginning of your comments.

Discussion ´ The Direccion Nacional de Aeronavegabilidad (DNA), which is the aviation authority for Republica Argentina, has issued AD No. RA 2006– 06–01, Rev. 1 LAVIA S.A., Amendment No. 39/03–041, dated November 17, 2006 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI ´ references Latinoamericana de Aviacion S.A. Service Bulletin No. 25/53/03, dated May 10, 2006, which states: REAR AND FORWARD SUPPORTS OF BOTH HORIZONTAL STABILIZER MODIFICATION. It have been found on several of the affected airplanes some severe corrosion and cracks in both supports. The probable cause for those failures is the accumulation of steam or application products vapors. The MCAI requires: Compliance with Service Bulletin No. 25/ ´ 53/03 issued by Latinoamericana de Aviacion S.A. is required in order to detect cracks, evidence of corrosion or any other anomalies on support tubes of the horizontal stabilizer. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information ´ Latinoamericana de Aviacion S.A. has issued Service Bulletin No. 25/53/03, dated May 10, 2006. 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 E:\FR\FM\14FEP1.SGM 14FEP1 Federal Register / Vol. 72, No. 30 / Wednesday, February 14, 2007 / 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 Based on the service information, we estimate that this proposed AD would affect about 1,144 products of U.S. registry. We also estimate that it would take about 10 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 $845 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 $1,881,880, or $1,645 per product. rmajette on PROD1PC67 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: VerDate Aug<31>2005 15:31 Feb 13, 2007 Jkt 211001 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] 2. The FAA amends § 39.13 by adding the following new AD: ´ LATINOAMERICANA DE AVIACION (LAVIA) S.A.

FOR FURTHER INFORMATION CONTACT: Cynthia C. Lynch, Office of the Deputy Commissioner for Trademark Examination Policy, by telephone at (571) 272–8742. SUPPLEMENTARY INFORMATION: The USPTO proposes the amendment of 37 CFR 2.64 to streamline and promote efficiency in the process once a final action has issued in an application for trademark registration. By setting a three-month period in which to file a request for reconsideration of the final action, and by requiring that the request be filed through TEAS, the proposed amendment would facilitate the likely disposition of an applicant’s request for reconsideration prior to the six-month deadline for filing an appeal to the Trademark Trial and Appeal Board (‘‘TTAB’’) or petition to the Director on the same final action. This may eliminate the need for some appeals or petitions, and reduces the need for remands and transfers of applications on appeal. A request for reconsideration of a final action does not extend the time for filing an appeal or petitioning the Director on that action. Under the current version of the rule, wherein the applicant may file a request for reconsideration at any time between the final action and the six-month deadline for appealing or petitioning, many applicants simultaneously seek reconsideration and file an appeal. Because the examining attorney loses jurisdiction over the application upon the filing of an appeal to the TTAB, this simultaneous pursuit of reconsideration and appeal often necessitates a remand by the TTAB to the examining attorney for a decision on the request for reconsideration. If the request is denied, then the case is transferred back to the TTAB. If the request is granted, and the examining attorney reconsiders the final E:\FR\FM\14FEP1.SGM 14FEP1

Airworthiness Directives; LATINOAMERICANA DE AVIACI[Oacute]N 
(LAVIA) S.A. (Type Certificate Data Sheets No. 2A8 and No. 2A10 
Previously Held by The New Piper Aircraft, Inc.) Models PA-25, PA-25-
235, and PA-25-260 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) 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 references Latinoamericana 
de Aviaci[oacute]n S.A. Service Bulletin No. 25/53/03, dated May 10, 
2006, which describes the unsafe condition as:

    REAR AND FORWARD SUPPORTS OF BOTH HORIZONTAL STABILIZER 
MODIFICATION. It have been found on several of the affected 
airplanes some severe corrosion and cracks in both supports. The 
probable cause for those failures is the accumulation of steam or 
application products vapors.

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 March 16, 2007.

ADDRESSES: You may send comments by any of the following methods:
     DOT Docket Web Site: Go to https://dms.dot.gov and follow

SUPPLEMENTARY INFORMATION: 

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. This streamlined process will allow us to adopt 
MCAI safety requirements in a more efficient manner and will reduce 
safety risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This proposed AD references the MCAI and related service 
information that we considered in forming the engineering basis to 
correct the unsafe condition. The proposed AD contains text copied from 
the MCAI and for this reason might not follow our plain language 
principles.

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-2007-
27109; Directorate Identifier 2007-CE-005-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://
dms.dot.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

    The Direcci[oacute]n Nacional de Aeronavegabilidad (DNA), which is 
the aviation authority for Republica Argentina, has issued AD No. RA 
2006-06-01, Rev. 1 LAVIA S.A., Amendment No. 39/03-041, dated November 
17, 2006 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI references 
Latinoamericana de Aviaci[oacute]n S.A. Service Bulletin No. 25/53/03, 
dated May 10, 2006, which states:

REAR AND FORWARD SUPPORTS OF BOTH HORIZONTAL STABILIZER 
MODIFICATION. It have been found on several of the affected 
airplanes some severe corrosion and cracks in both supports. The 
probable cause for those failures is the accumulation of steam or 
application products vapors.
    The MCAI requires:
    Compliance with Service Bulletin No. 25/53/03 issued by 
Latinoamericana de Aviaci[oacute]n S.A. is required in order to 
detect cracks, evidence of corrosion or any other anomalies on 
support tubes of the horizontal stabilizer.

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

Relevant Service Information

    Latinoamericana de Aviaci[oacute]n S.A. has issued Service Bulletin 
No. 25/53/03, dated May 10, 2006. 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

[[Page 6983]]

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

    Based on the service information, we estimate that this proposed AD 
would affect about 1,144 products of U.S. registry. We also estimate 
that it would take about 10 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 $845 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 $1,881,880, or $1,645 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.

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:

LATINOAMERICANA DE AVIACI[Oacute]N (LAVIA) S.A. (Type Certificate 
Data Sheets No. 2A8 and No. 2A10 previously held by The New Piper 
Aircraft, Inc.): Docket No. FAA-2007-27109; Directorate Identifier 
2007-CE-005-AD

Comments Due Date

    (a) We must receive comments by March 16, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Models PA-25, PA-25-235, and PA-25-260, 
all serial numbers up to LA-260-06008, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 55: 
Stabilizers.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
references Latinoamericana de Aviaci[oacute]n S.A. Service Bulletin 
No. 25/53/03, dated May 10, 2006, which states:
    REAR AND FORWARD SUPPORTS OF BOTH HORIZONTAL STABILIZER 
MODIFICATION. It has been found on several of the affected airplanes 
some severe corrosion and cracks in both supports. The probable 
cause for those failures is the accumulation of steam or application 
products vapors.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Upon accumulating 1,500 hours time-in-service (TIS) or 
within the next 50 hours TIS after the effective date of this AD, 
whichever occurs later, do the operations as specified in the 
paragraph ``ACTIONS,'' subparagraph ``INITIAL'' of Latinoamericana 
de Aviaci[oacute]n S.A. Service Bulletin No. 25/53/03, dated May 10, 
2006. Repetitively inspect thereafter every 100 hours TIS or 12 
months, whichever occurs first, until the modification specified in 
paragraph ``ACTIONS,'' subparagraph ``DEFINITIVE'' of 
Latinoamericana de Aviaci[oacute]n S.A. Service Bulletin No. 25/53/
03, dated May 10, 2006, is done.
    (2) If any evidence of cracks, signs of corrosion, or any other 
discrepancy is detected during any inspection required in paragraph 
(f)(1) of this AD, before further flight, disassemble both 
horizontal stabilizers and conduct a detailed inspection on the 
surface of both supports and take corrective action. Use paragraph 
``ACTIONS,'' subparagraph ``DEFINITIVE'' of Latinoamericana de 
Aviaci[oacute]n S.A. Service Bulletin No. 25/53/03, dated May 10, 
2006.
    (3) After incorporating the modification specified in paragraph 
``ACTIONS,'' subparagraph ``DEFINITIVE'' of Latinoamericana de 
Aviaci[oacute]n S.A. Service Bulletin No. 25/53/03, dated May 10, 
2006, no further action is required.
    (4) Upon accumulating 1,000 hours TIS after the effective date 
of this AD, modify both horizontal stabilizers as specified in 
paragraph ``ACTIONS,'' subparagraph ``DEFINITIVE'' of 
Latinoamericana de Aviaci[oacute]n S.A. Service Bulletin No. 25/53/
03, dated May 10, 2006, unless already done. Incorporating this 
modification terminates the repetitive inspection requirement in 
paragraph (f)(1) of this AD.
    (5) As a terminating action to the inspection requirements of 
this AD, the modification to both horizontal stabilizers specified 
in paragraph ``ACTIONS,'' subparagraph ``DEFINITIVE'' of 
Latinoamericana de Aviaci[oacute]n S.A. Service Bulletin No. 25/53/
03, dated May 10, 2006, may be incorporated at any time after the 
effective date of this AD and before the time required in paragraph 
(f)(4) of this AD.
