VerDate Nov<24>2008 16:58 Feb 13, 2009 Jkt 217001 DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2006–25730; Directorate Identifier 2006–NE–31–AD; Amendment 39– 15798; AD 2009–02–08] RIN 2120–AA64 Airworthiness Directives; Turbomeca Turmo IV A and IV C Series Turboshaft Engines AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule; request for comments. SUMMARY: The FAA is superseding an existing airworthiness directive (AD) for Turbomeca Turmo IV A and IV C series turboshaft engines. That AD is applicable to engines with oil-tank-tooil-cooler flexible lubrication pipes, part number (P/N) 0 249 92 813 0 or P/N 0 249 92 916 0, installed. That AD currently requires identifying, inspecting, and replacing affected flexible lubrication pipes manufactured after April 1, 2003. That AD also requires initial and repetitive borescope inspections of affected pipes, visual inspections for oil leakage, and visual inspections of the oil filter. That AD also requires that if both engines on the same helicopter each have an affected PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 New reduced published life limit, in flight cycles 23050752 23065303 23050752 23084157 23065303 23065303 15,200 13,300 11,400 11,400 6,200 5,000 23084158 23050754 23071259 23084159 23050728 23070729 23065300 6,200 14,900 14,900 14,900 2,900 2,900 9,500 pipe, replacing one of the affected pipes before further flight. This AD does not contain that requirement. This AD requires the same inspections as the superseded AD and adds inspection of oil-pump-to-intermediate-bearing flexible lubricating pipe, P/N 0 249 92 808 0. This AD also requires all remaining affected flexible lubrication pipes, P/N 0 249 92 813 0, P/N 0 249 92 916 0, and P/N 0 249 92 808 to be replaced as terminating action to the repetitive inspections for those affected pipes. This AD results from additional shutdowns caused by pipes, P/N 0 249 92 808 0, and the introduction of Turbomeca Modifications TU 231 and TU 233 that replace pipes, P/N 0 249 92 813 0, P/N 0 249 92 916 0, and P/N 0 249 92 808. We are issuing this AD to prevent helicopter engine in-flight shutdown of one or both engines resulting in an emergency auto-rotation landing or accident. DATES: Effective March 4, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of March 4, 2009. We must receive any comments on this AD by April 20, 2009.

SUPPLEMENTARY INFORMATION: On October 12, 2006, we issued AD 2006– 21–11, Amendment 39–14796 (71 FR 61642, October 19, 2006). That AD requires identifying and inspecting oiltank-to-oil-cooler flexible lubrication pipes, P/N 0 249 92 813 0 or P/N 0 249 92 916 0, manufactured after April 1, 2003. If both engines on the same helicopter each have an affected pipe, then that AD requires replacing one of the affected pipes before further flight. That AD also requires initial and repetitive borescope inspections of affected pipes, visual inspections for oil leakage, and visual inspections of the oil filter, on engines that are not required to have an affected pipe replaced before further flight. That AD resulted from seven reports of oil leakage due to the deterioration of certain flexible lubrication pipes manufactured after April 1, 2003. That condition, if not corrected, could result in helicopter engine in-flight shutdown of one or both engines resulting in an emergency autorotation landing or accident. jlentini on PROD1PC65 with RULES Actions Since AD 2006–21–11 Was Issued Since AD 2006–21–11 was issued, the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, notified us that Turbomeca reported two additional occurrences of deterioration in a third P/N flexible lubrication pipe, P/N 0 249 92 808 0. EASA also notified us that Turbomeca issued mandatory service bulletins to add pipe P/N 0 249 92 808 0 to the list of affected pipes, to replace affected pipes, P/N 0 249 92 813 0 and P/N 0 249 92 916 0 with a new P/N pipe, and to replace affected pipes, P/N 0 249 92 808 0 with a new P/N pipe. This AD requires the same inspections as AD 2006–21–11 but requires replacing all remaining affected lubrication pipes, P/ N 0 249 92 813 0 and P/N 0 249 92 916 0, with either a new P/N pipe or a pipe manufactured before April 1, 2003, as terminating action to the repetitive pipe inspections in this AD. Relevant Service Information We have reviewed and approved the technical contents of Turbomeca Alert Mandatory Service Bulletin (MSB) No. A249 72 0802, Update No. 2, dated February 23, 2007. That Alert MSB VerDate Nov<24>2008 16:58 Feb 13, 2009 Jkt 217001 describes procedures for identifying affected flexible lubrication pipes by their curing batch number, and describes procedures for performing repetitive borescope inspections of all other affected pipes and visual inspections of the oil filter. We have also reviewed and approved the technical contents of Turbomeca MSB No. 249 72 0231, Update No. 1, dated October 11, 2007. That MSB describes procedures for replacing remaining affected flexible lubrication pipes, P/N 0 249 92 813 0 and P/N 0 249 92 916 0, with pipes introduced by Modification TU 231. We have also reviewed and approved the technical contents of Turbomeca MSB No. 249 72 0233, dated September 1, 2008. That MSB describes procedures for replacing remaining affected flexible lubrication pipes, P/N 0 249 92 808 0, with pipes introduced by Modification TU 233. EASA classified these service bulletins as mandatory and issued AD 2008–0194 to ensure the airworthiness of these Turbomeca Turmo IV A and IV C series turboshaft engines in Europe. Bilateral Airworthiness Agreement These engine models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Under this bilateral airworthiness agreement, France has kept the FAA informed of the situation described above. We have examined the findings of EASA, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States. FAA’s Determination and Requirements of This AD The unsafe condition described previously is likely to exist or develop on other Turbomeca Turmo IV A and IV C series turboshaft engines of the same type design. We are issuing this AD to prevent engine in-flight shutdown of one or both helicopter engines resulting in an emergency auto-rotation landing or accident. This AD requires: • Identifying and inspecting certain flexible lubrication pipes manufactured after April 1, 2003; and • Initial and repetitive borescope inspections of affected pipes, visual inspections for oil leakage, and visual inspections of the oil filter, on engines that are not required to have an affected pipe replaced before further flight; and • Replacing all remaining affected lubrication pipes, P/N 0 249 92 813 0 PO 00000 Frm 00027 Fmt 4700 Sfmt 4700 7311 and P/N 0 249 92 916 0, and all remaining affected lubrication pipes, P/ N 0 249 92 808 0, with new P/N pipes or pipes manufactured before April 1, 2003, within 45 days or 50 operating hours after the effective date of the AD, whichever occurs first, as terminating action to the repetitive pipe inspections in this AD. FAA’s Determination of the Effective Date Since an unsafe condition exists that requires the immediate adoption of this AD, we have found that notice and opportunity for public comment before issuing this AD are impracticable, and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to send us any written relevant data, views, or arguments regarding this AD. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA– 2006–25730; Directorate Identifier 2006–NE–31–AD’’ in the subject line of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the rule that might suggest a need to modify it. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this proposed AD. Using the search function of the Web site, anyone can find and read the comments in any of our dockets, including, if provided, the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.). You may review the DOT’s complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477–78).

Comments will be available in the AD docket shortly after receipt. 1. The authority citation for part 39 continues to read as follows: ■ 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 have 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 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 summary of the costs to comply with this AD and placed it in the AD Docket. You may get a copy of this summary at the address listed under ADDRESSES.

ACTION: Final rule, technical correction. AGENCY: jlentini on PROD1PC65 with RULES SUMMARY: On January 15, 2009, HUD published a final rule to revise HUD’s regulations that govern the imposition of civil money penalties. The final rule contained, however, a typographical error in the amendatory language for a revision to 24 CFR 30.90(b). HUD published a second final rule on January 26, 2009, that further amended the section. Because of the error contained in the January 15, 2009 final rule, the amendatory language contained in the January 26, 2009, final rule was also in error. This document corrects these errors. DATES: Effective Dates: The correction to the amendment of 24 CFR 30.90 published on January 15, 2009 (74 FR 2750), is effective February 17, 2009. The correction to the amendment of § 30.90 published on January 26, 2009 (74 FR 4634), is effective February 25, 2009.

VerDate Nov<24>2008 16:58 Feb 13, 2009 Jkt 217001 On January 15, 2009 (74 FR 2750), HUD published a final rule that revised HUD’s regulations that govern the imposition of civil money penalties, located at part 30 of Title 24 of the Code of Federal Regulations. The final rule followed a proposed rule published on October 17, 2008 (73 FR 61754), that provided a 60 day public comment period. HUD received no comments in response to the proposed rule and, at the final rule stage, adopted the proposed rule without change. Among other changes, the January 15, 2009, final rule revised procedures at § 30.90 that detail how a respondent against whom HUD has filed a complaint seeking civil money penalties should submit his or her answer. In the January 15, 2009, final rule, HUD attempted to establish a new § 30.90(b) that instructed the respondent to serve upon HUD and file with the Office of Hearing and Appeals a written answer within 30 days of receipt of the complaint, unless such time is extended for good cause. The amendatory language for § 30.90 of the January 15, 2009, final rule, however, requested that the Federal Register redesignate existing paragraph (b) as (c) and ‘‘revise’’ new paragraph (b). Rather than requesting that new paragraph (b) be revised, the amendatory language should have instructed that new paragraph (b) be added. On January 26, 2009, HUD published a second final rule to amend several sections of HUD’s regulations to reflect changes in the office address and staff titles of HUD’s Office of Hearings and Appeals. Among the changes included in the January 26, 2009, final rule was one intended to amend § 30.90 of HUD’s civil money penalties rule to reflect that the title of ‘‘Chief Docket Clerk’’ has been changed to ‘‘Docket Clerk.’’ The amendatory language for § 30.90 in the January 26, 2009, final rule, however, contained a typographical error and requested that § 30.90(b) be revised. The amendatory language should have requested that § 30.90(c) be revised to conform to HUD’s January 15, 2009, final rule. Today’s Federal Register document corrects these errors. ■ Accordingly, FR Doc. E9–851, Civil Money Penalties: Certain Prohibited Conduct (FR–5081–F–02), published in the Federal Register on January 15, 2009 (74 FR 2750) is corrected as follows: SUPPLEMENTARY INFORMATION: § 30.90 [Corrected] On page 2752, in the second column, revise amendatory instruction number 11 to read as follows: ■ PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 7313 ‘‘11.

Airworthiness Directives; Turbomeca Turmo IV A and IV C Series 
Turboshaft Engines

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

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) for Turbomeca Turmo IV A and IV C series turboshaft engines. That 
AD is applicable to engines with oil-tank-to-oil-cooler flexible 
lubrication pipes, part number (P/N) 0 249 92 813 0 or P/N 0 249 92 916 
0, installed. That AD currently requires identifying, inspecting, and 
replacing affected flexible lubrication pipes manufactured after April 
1, 2003. That AD also requires initial and repetitive borescope 
inspections of affected pipes, visual inspections for oil leakage, and 
visual inspections of the oil filter. That AD also requires that if 
both engines on the same helicopter each have an affected pipe, 
replacing one of the affected pipes before further flight. This AD does 
not contain that requirement. This AD requires the same inspections as 
the superseded AD and adds inspection of oil-pump-to-intermediate-
bearing flexible lubricating pipe, P/N 0 249 92 808 0. This AD also 
requires all remaining affected flexible lubrication pipes, P/N 0 249 
92 813 0, P/N 0 249 92 916 0, and P/N 0 249 92 808 to be replaced as 
terminating action to the repetitive inspections for those affected 
pipes. This AD results from additional shutdowns caused by pipes, P/N 0 
249 92 808 0, and the introduction of Turbomeca Modifications TU 231 
and TU 233 that replace pipes, P/N 0 249 92 813 0, P/N 0 249 92 916 0, 
and P/N 0 249 92 808. We are issuing this AD to prevent helicopter 
engine in-flight shutdown of one or both engines resulting in an 
emergency auto-rotation landing or accident.

DATES: Effective March 4, 2009. The Director of the Federal Register 
approved the incorporation by reference of certain publications listed 
in the regulations as of March 4, 2009.
    We must receive any comments on this AD by April 20, 2009.

SUPPLEMENTARY INFORMATION: On October 12, 2006, we issued AD 2006-21-
11, Amendment 39-14796 (71 FR 61642, October 19, 2006). That AD 
requires identifying and inspecting oil-tank-to-oil-cooler flexible 
lubrication pipes, P/N 0 249 92 813 0 or P/N 0 249 92 916 0, 
manufactured after April 1, 2003. If both engines on the same 
helicopter each have an affected pipe, then that AD requires replacing 
one of the affected pipes before further flight. That AD also requires 
initial and repetitive borescope inspections of affected pipes, visual 
inspections for oil leakage, and visual inspections of the oil filter, 
on engines that are not required to have an affected pipe replaced 
before further flight. That AD resulted from seven reports of oil 
leakage due to the deterioration of certain flexible lubrication pipes 
manufactured after April 1, 2003. That condition, if not corrected, 
could result in helicopter engine in-flight shutdown of one or both 
engines resulting in an emergency auto-rotation landing or accident.

Actions Since AD 2006-21-11 Was Issued

    Since AD 2006-21-11 was issued, the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, notified us that Turbomeca reported two additional 
occurrences of deterioration in a third P/N flexible lubrication pipe, 
P/N 0 249 92 808 0. EASA also notified us that Turbomeca issued 
mandatory service bulletins to add pipe P/N 0 249 92 808 0 to the list 
of affected pipes, to replace affected pipes, P/N 0 249 92 813 0 and P/
N 0 249 92 916 0 with a new P/N pipe, and to replace affected pipes, P/
N 0 249 92 808 0 with a new P/N pipe. This AD requires the same 
inspections as AD 2006-21-11 but requires replacing all remaining 
affected lubrication pipes, P/N 0 249 92 813 0 and P/N 0 249 92 916 0, 
with either a new P/N pipe or a pipe manufactured before April 1, 2003, 
as terminating action to the repetitive pipe inspections in this AD.

Relevant Service Information

    We have reviewed and approved the technical contents of Turbomeca 
Alert Mandatory Service Bulletin (MSB) No. A249 72 0802, Update No. 2, 
dated February 23, 2007. That Alert MSB describes procedures for 
identifying affected flexible lubrication pipes by their curing batch 
number, and describes procedures for performing repetitive borescope 
inspections of all other affected pipes and visual inspections of the 
oil filter. We have also reviewed and approved the technical contents 
of Turbomeca MSB No. 249 72 0231, Update No. 1, dated October 11, 2007. 
That MSB describes procedures for replacing remaining affected flexible 
lubrication pipes, P/N 0 249 92 813 0 and P/N 0 249 92 916 0, with 
pipes introduced by Modification TU 231. We have also reviewed and 
approved the technical contents of Turbomeca MSB No. 249 72 0233, dated 
September 1, 2008. That MSB describes procedures for replacing 
remaining affected flexible lubrication pipes, P/N 0 249 92 808 0, with 
pipes introduced by Modification TU 233. EASA classified these service 
bulletins as mandatory and issued AD 2008-0194 to ensure the 
airworthiness of these Turbomeca Turmo IV A and IV C series turboshaft 
engines in Europe.

Bilateral Airworthiness Agreement

    These engine models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. Under this bilateral 
airworthiness agreement, France has kept the FAA informed of the 
situation described above. We have examined the findings of EASA, 
reviewed all available information, and determined that AD action is 
necessary for products of this type design that are certificated for 
operation in the United States.

FAA's Determination and Requirements of This AD

    The unsafe condition described previously is likely to exist or 
develop on other Turbomeca Turmo IV A and IV C series turboshaft 
engines of the same type design. We are issuing this AD to prevent 
engine in-flight shutdown of one or both helicopter engines resulting 
in an emergency auto-rotation landing or accident. This AD requires:
     Identifying and inspecting certain flexible lubrication 
pipes manufactured after April 1, 2003; and
     Initial and repetitive borescope inspections of affected 
pipes, visual inspections for oil leakage, and visual inspections of 
the oil filter, on engines that are not required to have an affected 
pipe replaced before further flight; and
     Replacing all remaining affected lubrication pipes, P/N 0 
249 92 813 0 and P/N 0 249 92 916 0, and all remaining affected 
lubrication pipes, P/N 0 249 92 808 0, with new P/N pipes or pipes 
manufactured before April 1, 2003, within 45 days or 50 operating hours 
after the effective date of the AD, whichever occurs first, as 
terminating action to the repetitive pipe inspections in this AD.

FAA's Determination of the Effective Date

    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we have found that notice and opportunity for 
public comment before issuing this AD are impracticable, and that good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment; however, we invite you to send us any written relevant data,

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 have 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 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 summary of the costs to comply with this AD and 
placed it in the AD Docket. You may get a copy of this summary at the 
address listed under ADDRESSES.
