Discussion On August 16, 2010, we issued AD 2010–18–02, Amendment 39–16415 (75 FR 52240, August 25, 2010), (‘‘AD 2010– 18–02’’), for certain Thielert Aircraft Engines GmbH (TAE) (previous certificate holder) models TAE 125–01 and TAE 125–02–99 reciprocating engines. AD 2010–18–02 resulted from reports of engine in-flight shutdowns. Preliminary investigation showed that nonconforming disc springs used in a certain production batch of the clutch caused the shutdowns. AD 2010–18–02 required replacement of certain clutch assemblies. On October 19, 2011, we superseded AD 2010–18–02, issuing AD 2011–23– 01, Amendment 39–16852 (76 FR 68636, November 7, 2011), for certain TAE models TAE 125–01 and TAE 125– 02–99 reciprocating engines. AD 2011– 23–01 required replacement of certain P/N and S/N clutch assemblies due to PO 00000 Frm 00009 Fmt 4700 Sfmt 4700 4765 clutch failure. AD 2011–23–01 resulted from TAE identifying additional clutch assemblies with nonconforming disc springs. Actions Since AD 2011–23–01 Was Issued Since we issued AD 2011–23–01, Amendment 39–16852 (76 FR 68636, November 7, 2011), we received an additional report of a malfunctioning clutch assembly. Investigation found that the same unsafe condition exists on approximately 40 additional S/N clutch assemblies that have nonconforming disk springs. Those additional nonconforming disc springs are identified in TMG Service Bulletin No. TM TAE 125–0021, Revision 2, dated October 13, 2014. FAA’s Determination We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of these same type designs. AD Requirements This AD requires, for engines with affected clutch assemblies with more than 100 hours time since new (TSN), replacement of affected clutch assemblies before further flight. This AD also requires, for those engines with affected clutch assemblies that have accumulated less than 100 hours TSN, replacement of affected clutch assemblies before accumulating 100 hours TSN. FAA’s Justification and 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 TMG identified additional clutch assemblies with nonconforming disc springs and the need for operators to comply with some of the AD actions before further flight. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. Costs of Compliance We estimate that this AD will affect about 111 engines installed on airplanes of U.S. registry. We also estimate that it will take about 16 hours per engine to perform the clutch assembly replacement. The average labor rate is $85 per hour. Required parts will cost about $1,796. Based on these figures, we E:\FR\FM\29JAR1.SGM 29JAR1 4766 Federal Register / Vol. 80, No. 19 / Thursday, January 29, 2015 / Rules and Regulations estimate the cost of the AD on U.S. operators to be $350,316. PART 39—AIRWORTHINESS DIRECTIVES 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 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), (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and (4) 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. Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing airworthiness directive (AD) 2011–23–01, Amendment 39–16852 (76 FR 68636, November 7, 2011), and adding the following new AD: ■ 2015–02–01 Technify Motors GmbH (Type Certificate previously held by Thielert Aircraft Engines GmbH): Amendment 39–18065; Docket No. FAA–2010–0683; Directorate Identifier 2010–NE–25–AD. (a) Effective Date This AD is effective February 13, 2015. (b) Affected ADs This AD supersedes AD 2011–23–01, Amendment 39–16852 (76 FR 68636, November 7, 2011). (c) Applicability This AD applies to Technify Motors GmbH (TMG) models TAE 125–01 and TAE 125– 02–99 reciprocating engines, with a clutch assembly part number (P/N) listed in paragraphs (c)(i) through (c)(v) of this AD, and with a serial number (S/N) listed in either TMG Service Bulletin (SB) No. TM TAE 125–0021, Revision 2, dated October 13, 2014, or Thielert Aircraft Engines GmbH (TAE) SB No. TM TAE 125–1011 P1, Revision 2, dated August 31, 2011, installed. (i) P/N 02–7210–11001R11 (ii) P/N 02–7210–11001R11–AT (iii) P/N 02–7210–11001R13 (iv) P/N 05–7211–K006001 (v) P/N 05–7211–K006002 (d) Unsafe Condition This AD was prompted by TMG identifying 40 additional S/N clutch assemblies with nonconforming disk springs for TMG TAE 125–01 reciprocating engines. We are issuing this AD to prevent failure of the clutch assembly, which could lead to failure of the engine, in-flight shutdown, and loss of control of the airplane. Adoption of the Amendment (e) Compliance Comply with this AD within the compliance times specified, unless already done. After the effective date of this AD: (1) For engines with affected clutch assemblies that have accumulated 100 hours time since new (TSN) or more, replace the clutch assembly before further flight. (2) For engines with affected clutch assemblies that have accumulated less than 100 hours TSN, replace the clutch assembly before accumulating 100 hours TSN. Accordingly, under the authority delegated to me by the Administrator, the FAA amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows: (f) Installation Prohibition After the effective date of this AD, do not install onto any airplane any engine having a clutch assembly, P/N 02–7210–11001R11, P/N 02–7210–11001R11–AT, P/N 02–7210– 11001R13, P/N 05–7211–K006001, or P/N List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. tkelley on DSK3SPTVN1PROD with RULES 1.

SUPPLEMENTARY INFORMATION: 14 CFR Part 39 Discussion [Docket No. FAA–2014–0876; Directorate Identifier 2014–CE–032–AD; Amendment 39–18076; AD 2015–02–09] We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to add an AD that would apply to Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. The NPRM was published in the Federal Register on October 29, 2014 (79 FR 64347). The NPRM proposed to correct an unsafe condition for the specified products and was based on mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country. The MCAI states: RIN 2120–AA64 Airworthiness Directives; Costruzioni Aeronautiche Tecnam srl Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 cracking found in the engine exhaust pipe. We are issuing this AD to require actions to address the unsafe condition on these products. DATES: This AD is effective March 5, 2015. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of March 5, 2015. ADDRESSES: You may examine the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2014– 0876; or in person at Document Management Facility, U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC 20590. For service information identified in this AD, contact Costruzioni Aeronautiche Tecnam Airworthiness Office, Via Maiorise–81043 Capua (CE) Italy; telephone: +39 0823 997538; fax: tkelley on DSK3SPTVN1PROD with RULES SUMMARY: VerDate Sep<11>2014 16:36 Jan 28, 2015 Jkt 235001 During a pre-flight inspection of a P2006T aeroplane, which included the opening of engine nacelle, a crack was found on the engine exhaust pipe Part Number (P/N) 26– 7–1800–1. This condition, if not detected and corrected, could lead to engine damage, possibly resulting in damage to the aeroplane and injury to the occupants. To address this potential unsafe condition, Costruzioni Aeronautiche TECNAM issued Service Bulletin (SB) SB 170–CS–Ed 1 Rev1. For the reason described above, this AD requires a one-time inspection of the affected engine exhaust pipes and, depending on findings, replacement. The MCAI can be found in the AD docket on the Internet at: http:// www.regulations.gov/ #!documentDetail;D=FAA-2014-08760002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes: PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 4767 • Are consistent with the intent that was proposed in the NPRM (79 FR 64347, October 29, 2014) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Relative Service Information We reviewed Costruzioni Aeronautiche TECNAM Service Bulletin No. SB 170–CS-Ed 1, Rev 1, dated September 25, 2014. The service bulletin describes procedures for inspecting and replacing (as necessary) the engine exhaust pipes. You can find this service information on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2014–0876. Costs of Compliance We estimate that this AD will affect 10 products of U.S. registry. We also estimate that it would take about .5 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $425, or $42.50 per product. In addition, we estimate that any necessary follow-on actions would take about .5 work-hour and require parts costing $343, for a cost of $385.50 per product. We have no way of determining the number of products that may need these actions. Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120–0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave. SW., Washington, DC 20591.

Airworthiness Directives; Technify Motors GmbH (Type Certificate 
Previously Held by Thielert Aircraft Engines GmbH) Reciprocating 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding airworthiness directive (AD) 2011-23-01 for 
all Technify Motors GmbH (TMG) models TAE 125-01 and TAE 125-02-99 
reciprocating engines with certain part number (P/N) and serial number 
(S/N) clutch assemblies installed. AD 2011-23-01 required replacement 
of certain P/N and S/N clutch assemblies. This AD requires the same 
actions but

[[Page 4765]]

expands the population of affected P/N and S/N clutch assemblies. This 
AD was prompted by an additional report of a clutch assembly that 
malfunctioned due to disk springs that received a nonconforming heat 
treatment process. We are issuing this AD to prevent failure of the 
clutch assembly, which could lead to failure of the engine, in-flight 
shutdown, and loss of control of the airplane.

Discussion

    On August 16, 2010, we issued AD 2010-18-02, Amendment 39-16415 (75 
FR 52240, August 25, 2010), (``AD 2010-18-02''), for certain Thielert 
Aircraft Engines GmbH (TAE) (previous certificate holder) models TAE 
125-01 and TAE 125-02-99 reciprocating engines. AD 2010-18-02 resulted 
from reports of engine in-flight shutdowns. Preliminary investigation 
showed that nonconforming disc springs used in a certain production 
batch of the clutch caused the shutdowns. AD 2010-18-02 required 
replacement of certain clutch assemblies.
    On October 19, 2011, we superseded AD 2010-18-02, issuing AD 2011-
23-01, Amendment 39-16852 (76 FR 68636, November 7, 2011), for certain 
TAE models TAE 125-01 and TAE 125-02-99 reciprocating engines. AD 2011-
23-01 required replacement of certain P/N and S/N clutch assemblies due 
to clutch failure. AD 2011-23-01 resulted from TAE identifying 
additional clutch assemblies with nonconforming disc springs.

Actions Since AD 2011-23-01 Was Issued

    Since we issued AD 2011-23-01, Amendment 39-16852 (76 FR 68636, 
November 7, 2011), we received an additional report of a malfunctioning 
clutch assembly. Investigation found that the same unsafe condition 
exists on approximately 40 additional S/N clutch assemblies that have 
nonconforming disk springs. Those additional nonconforming disc springs 
are identified in TMG Service Bulletin No. TM TAE 125-0021, Revision 2, 
dated October 13, 2014.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of these same type 
designs.

AD Requirements

    This AD requires, for engines with affected clutch assemblies with 
more than 100 hours time since new (TSN), replacement of affected 
clutch assemblies before further flight. This AD also requires, for 
those engines with affected clutch assemblies that have accumulated 
less than 100 hours TSN, replacement of affected clutch assemblies 
before accumulating 100 hours TSN.

FAA's Justification and 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 TMG 
identified additional clutch assemblies with nonconforming disc springs 
and the need for operators to comply with some of the AD actions before 
further flight. Therefore, we find that notice and opportunity for 
prior public comment are impracticable and that good cause exists for 
making this amendment effective in less than 30 days.

Costs of Compliance

    We estimate that this AD will affect about 111 engines installed on 
airplanes of U.S. registry. We also estimate that it will take about 16 
hours per engine to perform the clutch assembly replacement. The 
average labor rate is $85 per hour. Required parts will cost about 
$1,796. Based on these figures, we

[[Page 4766]]

estimate the cost of the AD on U.S. operators to be $350,316.

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

    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),
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction, and
    (4) 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.
