Download as PDF Federal Register / Vol. 82, No. 45 / Thursday, March 9, 2017 / Rules and Regulations 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 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 this AD: (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.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to the specified products. The NPRM was published in the Federal Register on November 1, 2016 (81 FR 75761). The NPRM proposed to correct an unsafe condition for the specified products. 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 AD requires 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. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Withdraw NPRM Delta Air Lines (Delta) requested that we withdraw the NPRM or reduce the applicability to RDS assemblies not returned to CFM. Delta stated that the suspect population will likely be in voluntary compliance by the effective date of this AD. Delta also stated that CFM requested that the affected parts be returned to CFM, which will ensure no returned parts are installed in the future. We disagree. The FAA has found that an unsafe condition exists, which requires removal of parts. The SB alone does not constitute a regulatory requirement, so this AD is required to mandate removal of parts from service. Compliance with the actions specified in this AD are mandatory, including the portions of the SB that are incorporated by reference (IBR) in this AD. We did not change this AD. Request To Revise Compliance Delta requested that this AD include a statement in the compliance section stating that compliance can be shown by a records review. Delta reasons that this will allow a credit for previous action. The phrase ‘‘unless already done . . .’’ in paragraph (f) of this AD already provides credit for operators that have complied with this AD before the effective date of this AD. We did not change this AD. Request To Revise Compliance CFM requested that we expand the applicability of this AD to include all CFM56–5 models not listed in paragraph (c) of this AD. CFM reasons that the affected RDS part numbers (P/ Ns) are eligible for installation on other CFM56–5 model series not listed in paragraph (c) of this AD. We disagree. We are issuing this AD to prevent failure of the RDS, which could lead to dual in-flight shutdown (IFSD), in the affected engines, loss of control, and damage to the airplane. RDS P/Ns are a known population and applicability represents those engines in which they were installed. We did not change this AD. Conclusion We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting this AD as proposed. Related Service Information Under 1 CFR Part 51 CFM International S.A. has issued Service Bulletin (SB) CFM56–5B S/B 72–0934, dated August 1, 2016. The SB describes procedures for removal of the affected 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. Costs of Compliance We estimate that this AD affects eight engines installed on airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action jstallworth on DSK7TPTVN1PROD with RULES Removal and replacement of the RDS assembly and RDS outer housing.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to the specified products. The 
NPRM was published in the Federal Register on November 1, 2016 (81 FR 
75761). The NPRM proposed to correct an unsafe condition for the 
specified products.
    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 AD requires 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Request To Withdraw NPRM

    Delta Air Lines (Delta) requested that we withdraw the NPRM or 
reduce the applicability to RDS assemblies not returned to CFM. Delta 
stated that the suspect population will likely be in voluntary 
compliance by the effective date of this AD. Delta also stated that CFM 
requested that the affected parts be returned to CFM, which will ensure 
no returned parts are installed in the future.
    We disagree. The FAA has found that an unsafe condition exists, 
which requires removal of parts. The SB alone does not constitute a 
regulatory requirement, so this AD is required to mandate removal of 
parts from service. Compliance with the actions specified in this AD 
are mandatory, including the portions of the SB that are incorporated 
by reference (IBR) in this AD. We did not change this AD.

Request To Revise Compliance

    Delta requested that this AD include a statement in the compliance 
section stating that compliance can be shown by a records review. Delta 
reasons that this will allow a credit for previous action.
    The phrase ``unless already done . . .'' in paragraph (f) of this 
AD already provides credit for operators that have complied with this 
AD before the effective date of this AD. We did not change this AD.

Request To Revise Compliance

    CFM requested that we expand the applicability of this AD to 
include all CFM56-5 models not listed in paragraph (c) of this AD. CFM 
reasons that the affected RDS part numbers (P/Ns) are eligible for 
installation on other CFM56-5 model series not listed in paragraph (c) 
of this AD.
    We disagree. We are issuing this AD to prevent failure of the RDS, 
which could lead to dual in-flight shutdown (IFSD), in the affected 
engines, loss of control, and damage to the airplane. RDS P/Ns are a 
known population and applicability represents those engines in which 
they were installed. We did not change this AD.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed.

Related Service Information Under 1 CFR Part 51

    CFM International S.A. has issued Service Bulletin (SB) CFM56-5B S/
B 72-0934, dated August 1, 2016. The SB describes procedures for 
removal of the affected 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.

Costs of Compliance

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

[[Page 13065]]

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 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
