Models PC–12, PC–12/45, and PC–12/47 Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. AGENCY: 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: This Airworthiness Directive (AD) is prompted by occurrences where abrasive damage (chafing) has been found on oil pipe assemblies in the area of the torque oil pressure transducer on the engines of some PC–12 aircraft. Incorrect assembly after maintenance tasks can decrease distances between various pipe/hoses assemblies and adjacent components. Damaged pipes can cause oil leakages in the area of the engine. PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 Discussion On October 17, 2000, we issued AD 2000–21–14, Amendment 39–11946 (65 FR 64340; October 27, 2000). That AD required actions intended to address an unsafe condition on the products listed above. Since we issued AD 2000–21–14, there have been reports of occurrences of abrasive damage (chafing) on oil pipe assemblies in the area of the torque oil pressure transducer on the engines of some Model PC–12 series airplanes. The damage has caused engine oil leakage in some airplanes. If uncorrected, the unsafe condition could result in engine failure. E:\FR\FM\16OCR1.SGM 16OCR1 58498 Federal Register / Vol. 72, No. 199 / Tuesday, October 16, 2007 / Rules and Regulations The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No: 2007– 0235, dated August 31, 2007, corrected September 14, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: This Airworthiness Directive (AD) is prompted by occurrences where abrasive damage (chafing) has been found on oil pipe assemblies in the area of the torque oil pressure transducer on the engines of some PC–12 aircraft. Incorrect assembly after maintenance tasks can decrease distances between various pipe/hoses assemblies and adjacent components. Damaged pipes can cause oil leakages in the area of the engine. For the reasons stated above, this AD requires an inspection for damage, replacement when damage is found, and eventual replacement of all the affected pipe/ hose assemblies. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Pilatus Aircraft Ltd. has issued Pilatus PC12 Service Bulletin No: 71–007, dated August 21, 2007. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. pwalker on PROD1PC71 with RULES 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. 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. VerDate Aug<31>2005 16:19 Oct 15, 2007 Jkt 214001 Any such differences are described in a separate paragraph of the AD. These requirements take precedence over those copied from the MCAI. 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 if uncorrected, the unsafe condition could result in engine failure. 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. 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–2007–29217; Directorate Identifier 2007–CE–075– 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 PO 00000 Frm 00030 Fmt 4700 Sfmt 4700 Regulatory Findings List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

    This Airworthiness Directive (AD) is prompted by occurrences 
where abrasive damage (chafing) has been found on oil pipe 
assemblies in the area of the torque oil pressure transducer on the 
engines of some PC-12 aircraft. Incorrect assembly after maintenance 
tasks can decrease distances between various pipe/hoses assemblies 
and adjacent components. Damaged pipes can cause oil leakages in the 
area of the engine.

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

SUPPLEMENTARY INFORMATION:

Discussion

    On October 17, 2000, we issued AD 2000-21-14, Amendment 39-11946 
(65 FR 64340; October 27, 2000). That AD required actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 2000-21-14, there have been reports of 
occurrences of abrasive damage (chafing) on oil pipe assemblies in the 
area of the torque oil pressure transducer on the engines of some Model 
PC-12 series airplanes. The damage has caused engine oil leakage in 
some airplanes. If uncorrected, the unsafe condition could result in 
engine failure.

[[Page 58498]]

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No: 2007-0235, dated August 31, 2007, corrected September 14, 2007 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    This Airworthiness Directive (AD) is prompted by occurrences 
where abrasive damage (chafing) has been found on oil pipe 
assemblies in the area of the torque oil pressure transducer on the 
engines of some PC-12 aircraft. Incorrect assembly after maintenance 
tasks can decrease distances between various pipe/hoses assemblies 
and adjacent components. Damaged pipes can cause oil leakages in the 
area of the engine.
    For the reasons stated above, this AD requires an inspection for 
damage, replacement when damage is found, and eventual replacement 
of all the affected pipe/hose assemblies.

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

Relevant Service Information

    Pilatus Aircraft Ltd. has issued Pilatus PC12 Service Bulletin No: 
71-007, dated August 21, 2007. 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.

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 if 
uncorrected, the unsafe condition could result in engine failure. 
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-2007-29217; Directorate 
Identifier 2007-CE-075-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 39-11946 (65 FR 
64340; October 27, 2000), and adding the following new AD:

2007-21-11 Pilatus Aircraft Limited: Amendment 39-15229; Docket No. 
FAA-2007-29217; Directorate Identifier 2007-CE-075-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective November 
5, 2007.

Affected ADs

    (b) This AD supersedes AD 2000-21-14, Amendment 39-11946.

Applicability

    (c) This AD applies to Models PC-12, PC-12/45, and PC-12-47 
airplanes, all serial numbers, that are:

[[Page 58499]]

    (1) Equipped with oil pipe/hose assemblies part number (P/N) 
577.11.12.104, 577.11.12.105, 946.37.74.305, 946.37.74.306, 
946.37.74.307, 946.37.74.308, or 946.37.74.311; and
    (2) certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 71: Power 
Plant-General.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    This Airworthiness Directive (AD) is prompted by occurrences 
where abrasive damage (chafing) has been found on oil pipe 
assemblies in the area of the torque oil pressure transducer on the 
engines of some PC-12 aircraft. Incorrect assembly after maintenance 
tasks can decrease distances between various pipe/hoses assemblies 
and adjacent components. Damaged pipes can cause oil leakages in the 
area of the engine.
    For the reasons stated above, this AD requires an inspection for 
damage, replacement when damage is found, and eventual replacement 
of all the affected pipe/hose assemblies.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1)Within the next 10 hours time-in-service after November 5, 
2007 (the effective date of this AD), do a configuration check and 
inspection of the pipe/hose assemblies for abrasive damage (chafing) 
and distortion following paragraph 3.B of Pilatus Aircraft Ltd. 
Pilatus PC12 Service Bulletin No: 71-007, dated August 21, 2007.
    (2) If during the configuration check and inspection required by 
paragraph (f)(1) of this AD any abrasive damage (chafing) on oil 
pipe/hose assemblies is found, before further flight, replace the 
hose/pipe assemblies following paragraphs 3.B, 3.C, and 3.E of 
Pilatus Aircraft Ltd. Pilatus PC12 Service Bulletin No: 71-007, 
dated August 21, 2007.
    (3) If during the configuration check and inspection required by 
paragraph (f)(1) of this AD no damage on oil pipe/hose assemblies is 
found, within 6 calendar months after November 5, 2007 (the 
effective date of this AD), replace the hose/pipe assemblies 
following paragraph 3.B, 3.C, and 3.E of Pilatus Aircraft Ltd. 
Pilatus PC12 Service Bulletin No: 71-007, dated August 21, 2007.
    (4) After November 5, 2007, do not install any oil pipe/hose 
assembly with P/N 577.11.12.104, 577.11.12.105, 946.37.74.305, 
946.37.74.306, 946.37.74.307, 946.37.74.308, or 946.37.74.311 on any 
Models PC-12, PC-12/45, or PC-12/47 airplanes.
    (5) After November 5, 2007, do not install a spare engine on any 
Models PC-12, PC-12/45, or PC-12/47 airplanes, unless it has been 
verified that no oil pipe/hose assembly with P/N 577.11.12.104, 
577.11.12.105, 946.37.74.305, 946.37.74.306, 946.37.74.307, 
946.37.74.308, or 946.37.74.311 are installed on that engine.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: The MCAI allows for the temporary replacement (up to 6 
months) of the hose/pipe assemblies with the same type that 
incorporate the potential unsafe condition (P/N 577.11.12.104, 
577.11.12.105, 946.37.74.305, 946.37.74.306, 946.37.74.307, 
946.37.74.308, or 946.37.74.311). Due to the urgency of this unsafe 
condition, the FAA is mandating replacement with the improved parts 
immediately if damage is found.

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

Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 
64106; telephone: (816) 329-4059; 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.
