14 CFR Part 39
[Docket No. FAA-2004-19928; Directorate Identifier 2004-NE-27-AD;
Amendment 39-14082; AD 2005-10-05]
RIN 2120-AA64
Airworthiness Directives; CFM International CFM56-5, -5B, and -5C
Series Turbofan Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for CFM
International CFM56-5, -5B, and -5C series turbofan engines. This AD
requires removing certain part number (P/N) air turbine starters from
service. This AD results from several reports of uncontained failures
of air turbine starters where high-energy particles were not contained
within the containment feature of the starter. We are issuing this AD
to prevent uncontained failures of air turbine starters, which could
result in damage to the airplane.
DATES: This AD becomes effective June 14, 2005.
ADDRESSES: You can get the service information identified in this AD
from CFM International, Technical Information Operation, One Neumann
Way, Cincinnati, OH 45215-1988.
You may examine the AD docket on the Internet at http://dms.dot.gov
or in Room PL-401 on the plaza level of the Nassif Building, 400
Seventh Street, SW., Washington, DC.
FOR FURTHER INFORMATION CONTACT: James Rosa, Aerospace Engineer, Engine
Certification Office, FAA, Engine and Propeller Directorate, 12 New
England Executive Park, Burlington, MA 01803-5299; telephone (781) 238-
7152; fax (781) 238-7199.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed airworthiness directive (AD). The proposed AD applies
to CFM International CFM56-5, -5B, and -5C series turbofan engines. We
published the proposed AD in the Federal Register on December 28, 2004
(69 FR 77677). That action proposed to require removing certain P/N air
turbine starters from service.
Examining the AD Docket
You may examine the docket that contains the AD, any comments
received, and any final disposition in person at the DMS Docket Offices
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Office (telephone (800) 647-5227) is located on
the plaza level of the Department of Transportation Nassif Building at
the street address stated in ADDRESSES. Comments will be available in
the AD docket shortly after the DMS receives them.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the two comments received.
One commenter states that the AD should mention only ``CFM56-5''
not ``CFM56-5 and CFM56-5A'' turbofan engines.
We agree. We have replaced references to ``CFM56-5 and CFM56-5A''
with ``CFM56-5''.
This commenter also indicated that the acronym ``CFMI'' is no
longer in use and should be replaced with ``CFM''.
We agree that this acronym is no longer used although the company
is still known as ``CFM International.'' We have, therefore, removed
references to ``CFMI'' and replaced them with ``CFM International'' or
``CFM.''
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.

Costs of Compliance
There are about 3,579 CFM International CFM56-5, -5B, and -5C
series turbofan engines of the affected design in the worldwide fleet.
We estimate that this AD will affect 600 air turbine starters installed
on airplanes of U.S. registry. We also estimate that it will take about
1 work hour per engine to perform these actions, and that the average
labor rate is $65 per work hour. Required parts will cost about $5,000
per air turbine starter. Based on these figures, we estimate the total
cost of the AD to U.S. operators to be approximately $3,039,000.
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.
Regulatory Findings
We have 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 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); 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 summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary at the
address listed under ADDRESSES.
