SUPPLEMENTARY INFORMATION: Discussion We received several reports of cracked engine exhaust pipes and exhaust studs pulling out from cylinders on Lycoming TIO–540–AJ1A reciprocating engines. This AD requires initial and repetitive inspections of all engine exhaust system weld joints and torque checking the exhaust pipe flange mounting nuts. We are issuing this AD to prevent engine exhaust leaks, which could lead to uncontrolled engine fire, harmful exhaust gases entering the cabin resulting in crew incapacitation, and damage to the airplane. Related Service Information Under 1 CFR Part 51 We reviewed Lycoming Engines Mandatory Service Bulletin (MSB) No. 627C, dated November 17, 2016. The MSB describes procedures for exhaust system inspection and flange nut torque check. 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. Other Related Service Information We reviewed Lycoming Engines MSB No. 614A, dated October 10, 2014, which provides maintenance instructions on the exhaust system for certain Lycoming engines. The FAA issued AD 2015–10–06, Amendment 39–18162 (80 FR 30345, May 28, 2015), (‘‘AD 2015–10–06’’) that mandates replacement of the turbocharger mounting bracket and inspection of the exhaust pipes in accordance with Lycoming Engines MSB No. 614A, dated October 10, 2014. The requirements in this AD are in addition to the requirements of AD 2015–10–06. Complying with AD 2015–10–06 and Lycoming Engines MSB No. 614A, dated October 10, 2014, does not constitute compliance with this AD. 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 the same type design. AD Requirements This AD requires initial and repetitive inspections of all engine exhaust system PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 26983 weld joints and torque checking the exhaust pipe flange mounting nuts. Differences Between This AD and the Service Information Table 1 of Lycoming Engines MSB No. 627C, dated November 17, 2016, provides a longer time between inspections of the engine exhaust system when an operational carbon monoxide detector is installed in the airplane. This AD does not consider whether an operational carbon monoxide detector is installed in the airplane. Interim Action We consider this AD interim action. Lycoming is determining the root cause for the unsafe condition identified in this AD. Once a root cause is determined, we will consider additional rulemaking. 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 engine exhaust leaks could lead to uncontrolled engine fire, harmful exhaust gases entering the cabin resulting in crew incapacitation, and damage to the airplane. 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. 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 any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA–2016–9512 and Directorate Identifier 2016–NE–27–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 http:// 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. E:\FR\FM\13JNR1.SGM 13JNR1 26984 Federal Register / Vol. 82, No. 112 / Tuesday, June 13, 2017 / Rules and Regulations Costs of Compliance We estimate that this AD affects 758 engines, installed on airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Inspection and torque check 1 work-hour × $85 per hour = $85 per inspection cycle .. nlaroche on DSK30NT082PROD with RULES 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. ATTN: Information Collection Clearance Officer, AES–200. 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 VerDate Sep<11>2014 14:51 Jun 12, 2017 Jkt 241001 Parts cost 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, 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.

SUPPLEMENTARY INFORMATION: 

Discussion

    We received several reports of cracked engine exhaust pipes and 
exhaust studs pulling out from cylinders on Lycoming TIO-540-AJ1A 
reciprocating engines. This AD requires initial and repetitive 
inspections of all engine exhaust system weld joints and torque 
checking the exhaust pipe flange mounting nuts. We are issuing this AD 
to prevent engine exhaust leaks, which could lead to uncontrolled 
engine fire, harmful exhaust gases entering the cabin resulting in crew 
incapacitation, and damage to the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Lycoming Engines Mandatory Service Bulletin (MSB) No. 
627C, dated November 17, 2016. The MSB describes procedures for exhaust 
system inspection and flange nut torque check. 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.

Other Related Service Information

    We reviewed Lycoming Engines MSB No. 614A, dated October 10, 2014, 
which provides maintenance instructions on the exhaust system for 
certain Lycoming engines. The FAA issued AD 2015-10-06, Amendment 39-
18162 (80 FR 30345, May 28, 2015), (``AD 2015-10-06'') that mandates 
replacement of the turbocharger mounting bracket and inspection of the 
exhaust pipes in accordance with Lycoming Engines MSB No. 614A, dated 
October 10, 2014. The requirements in this AD are in addition to the 
requirements of AD 2015-10-06. Complying with AD 2015-10-06 and 
Lycoming Engines MSB No. 614A, dated October 10, 2014, does not 
constitute compliance with this AD.

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 the same type design.

AD Requirements

    This AD requires initial and repetitive inspections of all engine 
exhaust system weld joints and torque checking the exhaust pipe flange 
mounting nuts.

Differences Between This AD and the Service Information

    Table 1 of Lycoming Engines MSB No. 627C, dated November 17, 2016, 
provides a longer time between inspections of the engine exhaust system 
when an operational carbon monoxide detector is installed in the 
airplane. This AD does not consider whether an operational carbon 
monoxide detector is installed in the airplane.

Interim Action

    We consider this AD interim action. Lycoming is determining the 
root cause for the unsafe condition identified in this AD. Once a root 
cause is determined, we will consider additional rulemaking.

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 
engine exhaust leaks could lead to uncontrolled engine fire, harmful 
exhaust gases entering the cabin resulting in crew incapacitation, and 
damage to the airplane. 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.

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 any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2016-9512 and 
Directorate Identifier 2016-NE-27-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 http://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.

Costs of Compliance

    We estimate that this AD affects 758 engines, installed on 
airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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. ATTN: Information 
Collection Clearance Officer, AES-200.

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, 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.
