We propose to adopt a new airworthiness directive (AD) for certain CFM International S.A. (CFM) CFM56-5B turbofan engines. This proposed AD was prompted by reports of the failure of the radial drive shaft (RDS) on CFM CFM56-5B engines. This proposed AD would require removal of the RDS assembly and the RDS outer housing and their replacement with parts eligible for installation. We are proposing this AD to prevent failure of the RDS, which could lead to failure of one or more engines, loss of thrust control, and damage to the airplane.

Airworthiness Directives; CFM International S.A. Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain CFM International S.A. (CFM) CFM56-5B turbofan engines. This 
proposed AD was prompted by reports of the failure of the radial drive 
shaft (RDS) on CFM CFM56-5B engines. This proposed AD would require 
removal of the RDS assembly and the RDS outer housing and their 
replacement with parts eligible for installation. We are proposing this 
AD to prevent failure of the RDS, which could lead to failure of one or 
more engines, loss of thrust control, and damage to the airplane.

DATES: We must receive comments on this proposed AD by December 16, 
2016.

SUPPLEMENTARY INFORMATION:

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2016-9128; 
Directorate Identifier 2016-NE-19-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed 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 proposed AD.

Discussion

    We have received 9 reports of failure of the RDS on CFM CFM56-5B 
engines. CFM has identified an affected population of RDSs suspected of 
generating unbalance levels that would lead to failure of the RDS 
bearing. This proposed AD would require removal of the RDS assembly and 
the RDS outer housing for the affected population. This condition, if 
not corrected, could result in failure of the RDS, which could lead to 
failure of one or more engines, loss of thrust control, and damage to 
the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed CFM Service Bulletin (SB) CFM56-5B S/B 72-0934, dated 
August 1, 2016. The service information describes procedures for 
removal of the suspect RDS assembly and the RDS outer housing. 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 proposing 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.

Proposed AD Requirements

    This proposed AD would require removal of the RDS assembly and the 
RDS outer housing and their replacement with parts eligible for 
installation.

Differences Between This Proposed AD and the Service Information

    CFM SB CFM56-5B S/B 72-0934, dated August 1, 2016, separates the 
affected RDS population into three batches with different removal dates 
for each batch. This proposed AD requires removal of the affected RDS 
assembly and RDS outer housing within 6 months of the effective date 
after this AD.

Costs of Compliance

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

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
