39-18988; AD 2017-16-11]
RIN 2120-AA64


Airworthiness Directives; Lycoming Engines Reciprocating Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
models of Lycoming Engines reciprocating engines. This AD requires an 
inspection of connecting rods and replacement of affected connecting 
rod small end bushings. This AD was prompted by several reports of 
connecting rod failures resulting in uncontained engine failure and in-
flight shutdowns (IFSDs). We are issuing this AD to address the unsafe 
condition on these products.

SUPPLEMENTARY INFORMATION: 

Discussion

    We have received 5 reports of uncontained engine failures and IFSDs 
due to failed connecting rods on various models of Lycoming Engines 
reciprocating engines listed in Table 1 of Lycoming Engines Mandatory 
Service Bulletin (MSB) No. 632B, dated August 4, 2017, that were 
overhauled or repaired using any replacement part listed in Table 2 of 
Lycoming Engines MSB No. 632B, dated August 4, 2017,

[[Page 37297]]

which was shipped from Lycoming Engines during the dates listed in 
Table 2 of Lycoming Engines MSB No. 632B, dated August 4, 2017. This AD 
requires accomplishing the instructions in Lycoming Engines MSB No. 
632B, dated August 4, 2017, except for the instruction to complete the 
online survey as specified in the MSB. This condition, if not 
corrected, could result in uncontained engine failure, total engine 
power loss, IFSD, and possible loss of the airplane. We are issuing 
this AD to prevent connecting rod failure.

Related Service Information Under 1 CFR Part 51

    Lycoming Engines Mandatory Service Bulletin (MSB) No. 632B, dated 
August 4, 2017. The MSB describes procedures for inspecting connecting 
rods and replacing connecting rod small end bushings. 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

    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 accomplishing the actions specified in the service 
information described previously, except as discussed under 
``Differences Between the AD and the Service Information''.

Differences Between This AD and the Service Information

    Lycoming Engines MSB No. 632B, dated August 4, 2017 requires you to 
complete an online survey at www.lycoming.com/SB632, review your 
inventory of any part listed in Table 2 of the MSB, and sending certain 
parts to Lycoming Engines. This AD does not include those requirements.

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 
compliance is required within 10 operating hours. 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 final rule. Send your comments to an address 
listed under the ADDRESSES section. Include the docket number FAA-2017-
0788 and Product Identifier 2017-NE-27-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this final rule. We will 
consider all comments received by the closing date and may amend this 
final rule 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 final rule.

Costs of Compliance

    We estimate that this AD affects 778 engines installed on airplanes 
of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs

            Action                    Labor cost           Parts cost        product      Cost on U.S. operators

                                inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the inspection. We have 
no way of determining the number of aircraft that might need these 
replacements:

                                               On-Condition Costs

 engine.                                         $1,530.00.
Connecting rod replacement on 8-cylinder        20 work-hours x $85 per hour =          5,150.00        6,850.00
 engine.                                         $1,700.00.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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

[[Page 37298]]

products identified in this rulemaking action.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

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.
