pwalker on PROD1PC71 with RULES
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for CFM
International, S. A. CFM56–5B series
turbofan engines. This AD requires
reviewing exhaust gas temperature
(EGT) monitoring records to determine
EGT deterioration margin, and for
airplanes where both engines have
greater than 80° centigrade (C)
deterioration of EGT margin, borescopeinspecting the high-pressure compressor
(HPC) of both engines. This AD also
requires removing from service any
engine that does not pass the borescope
inspection, and if both engines pass,
removing and replacing one of the
engines with an engine that has 80 °C
or less deterioration of EGT margin.
This AD also requires continuous
monitoring of EGT margin on engines in
service, to prevent two engines on an
airplane from having greater than 80 °C
of deterioration of EGT margin. This AD
results from an Airbus A321 airplane
powered by CFM56–5B1/P turbofan
engines experiencing HPC stalls during
climb out after takeoff. We are issuing
this AD to prevent HPC stalls, which
could prevent continued safe flight or
landing.
DATES: This AD becomes effective
December 31, 2008.
We must receive any comments on
this AD by March 2, 2009.

SUPPLEMENTARY INFORMATION: On
December 15, 2008, an Airbus A321
airplane powered by CFM56–5B1/P
turbofan engines experienced HPC stalls
in both engines during climb out after
takeoff. The flight crew restored power
to both engines by retarding the throttles
to flight idle. The crew continued the
climb out phase of the flight, declared
an emergency, and returned to the
airport without incident. This
condition, if not corrected, could result
in HPC stalls, which could prevent
continued safe flight or landing.
FAA’s Determination and Requirements
of This AD
The unsafe condition described
previously is likely to exist or develop
on other CFM International, S. A.
CFM56–5B series turbofan engines of
the same type design. For that reason,
we are issuing this AD to prevent HPC
stalls, which could prevent continued
safe flight or landing. This AD requires
the following:
• Reviewing EGT monitoring records
to determine EGT deterioration margin;
and
• For airplanes where both engines
have greater than 80 °C deterioration of
EGT margin, doing the following:
• Borescope-inspecting HPC stages 1,
3, 6, and 9 of both engines.
• Removing from service any engine
that does not pass the borescope
inspection; and
• If both engines pass the borescope
inspection, then removing one of the
engines from service and replacing it
with an engine that has 80 °C or less
deterioration of EGT margin.
FAA’s Determination of the Effective
Date
Since an unsafe condition exists that
requires the immediate adoption of this
AD, we have found that notice and
opportunity for public comment before
issuing this AD are impracticable, and
that good cause exists for making this
amendment effective in less than 30
days.
Interim Actions
These actions are interim actions and
we anticipate further rulemaking actions
in the future, including further action to
address the remaining engines in service

that are above 80 °C deterioration of
EGT margin.
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 us any
written relevant data, views, or
arguments regarding this AD. Send your
comments to an address listed under
ADDRESSES. Include ‘‘AD Docket No.
FAA–2008–1353; Directorate Identifier
2008–NE–46–AD’’ in the subject line of
your comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of the rule that might suggest a
need to modify it.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact with FAA
personnel concerning this AD. Using the
search function of the Web site, anyone
can find and read the comments in any
of our dockets, including, if provided,
the name of the individual who sent the
comment (or signed the comment on
behalf of an association, business, labor
union, etc.). You may review the DOT’s
complete Privacy Act Statement in the
Federal Register published on April 11,
2000 (65 FR 19477–78).
Examining the AD Docket
You may examine the AD docket on
the Internet at https://
www.regulations.gov; or in person at the
Docket Operations office between 9 a.m.
and 5 p.m., Monday through Friday,
except Federal holidays. The AD docket
contains this AD, the regulatory
evaluation, any comments received, and
other information. The street address for
the Docket Operations office (telephone
(800) 647–5527) is the same as the Mail
address provided in the ADDRESSES
section. Comments will be available in

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
E:\FR\FM\31DER1.SGM
31DER1
Federal Register / Vol. 73, No. 251 / Wednesday, December 31, 2008 / Rules and Regulations
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 the
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.
