SUPPLEMENTARY INFORMATION: 14 CFR Part 39 [Docket No. FAA–2007–27208; Directorate Identifier 2007–CE–010–AD] RIN 2120–AA64 Airworthiness Directives; Vulcanair S.p.A. P68 Series Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). AGENCY: 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 describes the unsafe condition as: erjones on PRODPC74 with PROPOSALS The backrest recline of pilot and copilot seats requires the removal of a ‘‘quick release pin’’ not correctly indicated in the AFM and not ready detectable by the passengers. Moreover the operation of removal the device is difficult. This cause difficulty or disables the access to the escapes of the cabin in case of emergency evacuation. 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 April 9, 2007. ADDRESSES: You may send comments by any of the following methods: • DOT Docket Web Site: Go to https://dms.dot.gov and follow the instructions for sending your comments electronically. • Fax: (202) 493–2251. • Mail: Docket Management Facility, U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, Room PL–401, Washington, DC 20590– 0001. VerDate Aug<31>2005 14:34 Mar 08, 2007 Jkt 211001 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. PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 FAA–2007–27208; Directorate Identifier 2007–CE–010–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 Ente Nazionale per l’Aviazione Civile (ENAC), which is the aviation authority for Italy, has issued AD N. 2004–522, Rev. 0, dated December 20, 2004 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: The backrest recline of pilot and copilot seats requires the removal of a ‘‘quick release pin’’ not correctly indicated in the AFM and not ready detectable by the passengers. Moreover the operation of removal the device is difficult. This cause difficulty or disables the access to the escapes of the cabin in case of emergency evacuation. The MCAI requires: Carry out the operational checks/ inspection/modification: —Kit SB 128/A–1 applicable to aircraft model P68C. Serial numbers (S/N) 429, 434 and 435 are excluded; —Kit SB 128/A–2 applicable only to P68C aircraft with S/N 429, 434 and 435; —Kit SB 128/B applicable to aircraft model P68 Observer 2; —Kit SB 128/C applicable to aircraft model P68TC Observer; called for by the referenced Service Bulletin, in accordance with the procedures in there specified, within the terms set forth under ‘‘COMPLIANCE’’ of this AD. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Vulcanair S.p.A. has issued P68 Variants Mandatory Service Bulletin No. 128, dated October 12, 2004. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. E:\FR\FM\09MRP1.SGM 09MRP1 Federal Register / Vol. 72, No. 46 / Friday, March 9, 2007 / Proposed Rules 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. erjones on PRODPC74 with PROPOSALS Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 15 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. 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 $2,400, or $160 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, VerDate Aug<31>2005 14:34 Mar 08, 2007 Jkt 211001 10621 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. Affected ADs 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. (e) The mandatory continuing airworthiness information (MCAI) states: 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.

ACTION: Notice of proposed rulemaking (NPRM). erjones on PRODPC74 with PROPOSALS AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) for certain Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD currently requires initial and repetitive position checks of the gas generator 2nd stage turbine blades on all Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD also currently requires initial and repetitive replacements of 2nd stage turbines on 1B, 1D, and 1D1 engines only. This proposed AD would require adding a 3,000 hour life limit to Arriel 1B 2nd Stage Turbine Blades. This proposed AD results from reports of failures of second stage blades. We are proposing this AD to prevent failures of the 2nd stage turbine blades, which could result in uncommanded in-flight engine shutdown, and subsequent forced autorotation landing or accident.

That AD requires initial and repetitive position checks of the gas generator 2nd stage turbine blades on all Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines, and initial and repetitive replacements of 2nd stage turbines on 1B, 1D, and 1D1 engines only. The Direction Generale de L’Aviation Civile (DGAC), which is the airworthiness authority for France, notified the FAA that an unsafe condition might exist on Turbomeca, Arriel 1B (modified per TU 148), 1D, 1D1, and 1S1 turboshaft engines. The DGAC advises that sixteen cases of release of gas generator 2nd stage turbine blades occurred in service, with full containment of debris. These events resulted in uncommanded inflight engine shutdowns. Although terminating action is still unavailable, mandatory checks of the turbine blades and replacement of the turbine are being required in order to reduce the probability of an uncommanded inflight engine shutdown. That AD requires initial and repetitive position checks of the gas generator 2nd stage turbine blades on all Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD also requires initial and repetitive replacements of 2nd stage turbines on 1B, 1D, and 1D1 engines only. That condition, if not corrected, could result in uncommanded in-flight engine shutdown. Actions Since AD 2006–02–08R1 Was Issued Since we issued that AD, the European Aviation Safety Agency (EASA) informed us that they have received reports of additional failures of the 2nd stage turbine blades. The debris from the failures was fully contained. The failures were caused by: E:\FR\FM\09MRP1.SGM 09MRP1

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 describes the unsafe 
condition as:

    The backrest recline of pilot and copilot seats requires the 
removal of a ``quick release pin'' not correctly indicated in the 
AFM and not ready detectable by the passengers. Moreover the 
operation of removal the device is difficult. This cause difficulty 
or disables the access to the escapes of the cabin in case of 
emergency evacuation.

    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 April 9, 2007.

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

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-
27208; Directorate Identifier 2007-CE-010-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 Ente Nazionale per l'Aviazione Civile (ENAC), which is the 
aviation authority for Italy, has issued AD N. 2004-522, Rev. 0, dated 
December 20, 2004 (referred to after this as ``the MCAI''), to correct 
an unsafe condition for the specified products. The MCAI states:

    The backrest recline of pilot and copilot seats requires the 
removal of a ``quick release pin'' not correctly indicated in the 
AFM and not ready detectable by the passengers. Moreover the 
operation of removal the device is difficult. This cause difficulty 
or disables the access to the escapes of the cabin in case of 
emergency evacuation.
    The MCAI requires:
    Carry out the operational checks/inspection/modification:

--Kit SB 128/A-1 applicable to aircraft model P68C. Serial numbers 
(S/N) 429, 434 and 435 are excluded;
--Kit SB 128/A-2 applicable only to P68C aircraft with S/N 429, 434 
and 435;
--Kit SB 128/B applicable to aircraft model P68 Observer 2;
--Kit SB 128/C applicable to aircraft model P68TC Observer; called 
for by the referenced Service Bulletin, in accordance with the 
procedures in there specified, within the terms set forth under 
``COMPLIANCE'' of this AD.

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

Relevant Service Information

    Vulcanair S.p.A. has issued P68 Variants Mandatory Service Bulletin 
No. 128, dated October 12, 2004. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

[[Page 10621]]

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

    Based on the service information, we estimate that this proposed AD 
would affect about 15 products of U.S. registry. We also estimate that 
it would take about 2 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. 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 $2,400, or $160 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:

Vulcanair S.p.A. (Type certificate No. A31EU formally held by 
Partenavia Costruzioni Aeronautiche S.p.A.): Docket No. FAA-2007-
27208; Directorate Identifier 2007-CE-010-AD

Comments Due Date

    (a) We must receive comments by April 9, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to all Models P68C, P68 Observer 2, and 
P68TC Observer airplanes, serial numbers 412 through 424 (except 
418), 429, 434, and 435, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 51: 
Structures.

Reason

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

    The backrest recline of pilot and copilot seats requires the 
removal of a ``quick release pin'' not correctly indicated in the 
AFM and not ready detectable by the passengers. Moreover the 
operation of removal the device is difficult. This cause difficulty 
or disables the access to the escapes of the cabin in case of 
emergency evacuation.

Actions and Compliance

    (f) Unless already done, do the following actions within 30 days 
after the effective date of this AD:
    (1) For Model P68C airplanes, serial numbers 412 through 424 
(except 418): Install Kit SB 128/A-1, following Vulcanair S.p.A. P68 
Variants Mandatory Service Bulletin No. 128, dated October 12, 2004;
    (2) For Model P68C airplanes, serial numbers 429, 434, and 435:

    (3) For Model P68 Observer 2 airplanes: Install Kit SB 128/B, 
following Vulcanair S.p.A. P68 Variants Mandatory Service Bulletin 
No. 128, dated October 12, 2004; or
    (4) For Model P68TC Observer airplanes: Install Kit SB 128/C, 
following Vulcanair S.p.A. P68 Variants Mandatory Service Bulletin 
No. 128, dated October 12, 2004.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: No differences.
