Airworthiness Directives; Thielert Aircraft Engines GmbH (TAE) Model TAE 125-01 Reciprocating Engines, 47760-47762 [E9-22314]

Download as PDF 47760 Federal Register / Vol. 74, No. 179 / Thursday, September 17, 2009 / Proposed Rules States. Pursuant to our bilateral agreement with Germany, 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 the modification of the engine oil system by installing a filter adaptor to the catch tank. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 250 products of U.S. registry. We also estimate that it would take about one work-hour per product to comply with this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $80 per product. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $40,000. 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. cprice-sewell on DSK2BSOYB1PROD with PROPOSALS 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; VerDate Nov<24>2008 13:48 Sep 16, 2009 Jkt 217001 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, Incorporation by reference, 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. The FAA amends § 39.13 by adding the following new AD: Thielert Aircraft Engines GmbH: Docket No. FAA–2009–0747; Directorate Identifier 2009–NE–28–AD. Comments Due Date (a) We must receive comments by October 19, 2009. Affected Airworthiness Directives (ADs) (b) None. Applicability (c) This AD applies to Thielert Aircraft Engines GmbH (TAE) model TAE 125–01 reciprocating engines, all serial numbers (SN) up to-and-including SN 02–01–1018. These engines are installed in, but not limited to, Diamond Aircraft Industries Model DA42, Piper PA–28–61 (Supplemental Type Certificate (STC) No. SA03303AT), Cessna 172F, 172G, 172H, 172I, 172K, 172L, 172M, 172N, 172P, 172R, 172S, F172F, F172G, F172H, F172K, F172L, F172M, F172N, and F172P (STC No. SA01303WI) airplanes. Reason (d) 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: An in-flight engine shutdown incident was reported on an aircraft equipped with a TAE 125–01 engine. This was found to be mainly the result of a blockage of the scavenge oil gear pump due to a broken axial bearing of the turbocharger. The broken parts were sucked into the oil pump and caused seizure. PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 With the pump inoperative, the separator overfilled, causing the engine oil to escape via the breather vent line. This caused a loss of oil that resulted in the engine overheating and subsequent shutdown. We are issuing this AD to prevent engine inflight shutdown, possibly resulting in reduced control of the aircraft. Actions and Compliance (e) Unless already done, do the following actions within the next 50 flight hours after the effective date of this AD: (1) Modify the engine oil system by installing a filter adaptor to the catch tank. (2) Use the installation instructions in Thielert Service Bulletin No. TM TAE 125– 0016, Revision 1, dated June 15, 2007, to install the filter adaptor. FAA AD Differences (f) This AD differs from the Mandatory Continuing Airworthiness Information (MCAI) as follows: (1) The MCAI compliance time states ‘‘within the next 50 flight hours after the effective date of this directive, but not later than 31 October 2007, whichever occurs first’’. (2) This AD compliance time states ‘‘within the next 50 flight hours after the effective date of this AD.’’ Related Information (g) Refer to European Aviation Safety Agency AD 2007–0232, dated August 23, 2007, for related information.

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

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) 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:

    In-flight engine shutdown incidents were reported on aircraft 
equipped with TAE-125-01 engines. This was found to be mainly the 
result of operation over a long time period with broken piston 
cooling oil nozzles which caused thermal overload of the piston.

    We are proposing this AD to prevent engine in-flight shutdown, 
possibly resulting in reduced control of the aircraft.

DATES: We must receive comments on this proposed AD by October 19,

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2007-0232, dated August 23, 2007 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    In-flight engine shutdown incidents were reported on aircraft 
equipped with TAE-125-01 engines. This was found to be mainly the 
result of operation over a long time period with broken piston 
cooling oil nozzles which caused thermal overload of the piston.

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

Relevant Service Information

    Thielert has issued Service Bulletin No. TM TAE 125-0017, Revision 
2, dated February 22, 2008. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

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 Germany, 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.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 250 engines of U.S. registry. We also estimate that 
it would take about 2 work-hours per engine to comply with this 
proposed AD. The average labor rate is $80 per work-hour. Required 
parts would cost about $30 per engine. Based on these figures, we 
estimate the cost of the proposed AD on U.S. operators to be $47,500.

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;

[[Page 47762]]

    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.

Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Thielert Aircraft Engines GmbH: Docket No. FAA-2009-0753; 
Directorate Identifier 2009-NE-31-AD.

Comments Due Date

    (a) We must receive comments by October 19, 2009.

Affected Airworthiness Directives (ADs)

    (b) None.

Applicability

    (c) This AD applies to Thielert Aircraft Engines GmbH (TAE) 
model TAE 125-01 reciprocating engines, excluding engines that have 
been modified to TAE Design Modification No. 2007-001. These engines 
are installed in, but not limited to, Diamond Aircraft Industries 
Model DA42, Piper PA-28-61 (Supplemental Type Certificate (STC) No. 
SA03303AT), Cessna 172F, 172G, 172H, 172I, 172K, 172L, 172M, 172N, 
172P, 172R, 172S, F172F, F172G, F172H, F172K, F172L, F172M, F172N, 
and F172P (STC No. SA01303WI) airplanes.

Reason

    (d) 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:
    In-flight engine shutdown incidents were reported on aircraft 
equipped with TAE-125-01 engines. This was found to be mainly the 
result of operation over a long time period with broken piston 
cooling oil nozzles which caused thermal overload of the piston.
    We are issuing this AD to prevent engine in-flight shutdown, 
possibly resulting in reduced control of the aircraft.

Actions and Compliance

    (e) Unless already done, do the following actions:
    (1) Within the next 110 flight hours, or during the next 
scheduled maintenance, whichever occurs first after the effective 
date of this AD, inspect the engine and engine oil for any evidence 
or pieces of broken piston cooling nozzles.
    (2) Use the inspection instructions in Thielert Service Bulletin 
No. TM TAE 125-0017, Revision 2, dated February 22, 2008, to perform 
the inspection.
    (3) Thereafter, repetitively inspect the engine and engine oil 
for any evidence or pieces of broken piston cooling nozzles, within 
every additional 100 flight hours.
    (4) If any evidence of a failed cooling nozzle is found, remove 
the engine from service before further flight.

Alternative Methods of Compliance (AMOCs)

    (f) The Manager, Engine Certification Office, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19.
