We propose to adopt a new airworthiness directive (AD) for certain Technify Motors GmbH TAE 125-02 reciprocating engines. This proposed AD was prompted by a loss of engine power in flight caused by oil leaking from the gearbox radial shaft sealing ring that contaminated the clutch. This proposed AD would require replacement of the clutch with a dual mass flywheel. We are proposing this AD to correct the unsafe condition on these products.

Airworthiness Directives; Technify Motors GmbH Reciprocating

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Technify Motors GmbH TAE 125-02 reciprocating engines. This

oil leaking from the gearbox radial shaft sealing ring that 
contaminated the clutch. This proposed AD would require replacement of 
the clutch with a dual mass flywheel. We are proposing this AD to 
correct the unsafe condition on these products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2017-0034, dated February 20, 2017 (referred to hereinafter as ``the 
MCAI''), to correct an unsafe condition for the specified products.
    The MCAI states:

    A temporary power loss occurred during flight on a TAE 125-02-
powered aeroplane. Following investigation, it was determined that 
an improper lapping of the gearbox driveshaft led to insufficient 
sealing of the gearbox radial shaft sealing ring, eventually 
resulting in oil leakage and oil contamination of the clutch.
    This condition, if not detected and corrected, could lead to 
permanent engine power loss, possibly resulting in reduced control 
of the aeroplane.

    You may obtain further information by examining the MCAI in the AD 
docket on the Internet at http://www.regulations.gov by searching for 
and locating Docket No. FAA-2017-0241.

Related Service Information Under 1 CFR Part 51

    Technify Motors GmbH has issued Service Bulletin (SB) No. SB TMG 
125-1020 P1, Initial Issue, dated January 27, 2016. The SB describes 
procedures for replacing the clutch with a dual mass flywheel. This 
service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of 
Germany, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the European Community, EASA has 
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 provided by EASA and determined the unsafe 
condition exists and is likely to exist or develop on other products of 
the same type design. This proposed AD would require replacing the 
clutch with a dual mass flywheel.

Costs of Compliance

    We estimate that this proposed AD affects 4 engines installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

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

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),
    (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.

reference, Safety.

(d) Subject

    Joint Aircraft System Component (JASC) Code 8510, Reciprocating 
Engine Front Section.

(e) Reason

    This AD was prompted by a loss of engine power in flight caused 
by oil leaking from the gearbox radial shaft sealing ring that 
contaminated the clutch. We are proposing this AD to prevent failure 
of the clutch, loss of engine power in flight, and reduced control 
of the airplane.

(f) Compliance

    (1) Comply with this AD within the compliance times specified, 
unless already done.
    (2) Within 55 flight hours after the effective date of this AD:
    (i) Replace the clutch with a dual mass flywheel. Use Technify 
Motors Service Bulletin (SB) No. SB TMG 125-1020 P1, Initial Issue, 
dated January 27, 2016, to do the replacement.
    (ii) Install a start phase monitoring system and software 
mapping in accordance with the requirements of FAA AD 2015-21-01 (80 
FR 64314, October 23, 2015); and
    (iii) Inspect the rear radial shaft sealing ring on the gearbox 
for oil leakage in accordance with Figures 2 and 3 of Technify 
Motors SB No. SB TMG 125-1020 P1, Initial Issue, dated January 27, 
2016. If an oil leak is detected, replace the gearbox with a part 
eligible for installation before the next flight.

(g) Installation Prohibition

    After the effective date of this AD:
    (1) Do not install an engine that is equipped with a clutch and 
has an affected gearbox listed in Figure 1 to paragraph (c) of this 
AD;
    (2) Do not install an affected gearbox on an engine unless it 
has passed the inspection required by paragraph (f)(2)(iii) of this 
AD; and
    (3) Do not install a clutch on an engine previously modified in 
accordance with the requirements of paragraph (f)(2) of this AD or 
already incorporating a dual mass flywheel.

(h) Alternative Methods of Compliance (AMOCs)

    The Manager, Engine Certification Office, FAA, may approve AMOCs 
for this AD. Use the procedures found in 14 CFR 39.19 to make your 
request. You may email your request to: [email protected].
