(NPRM).
ACTION:
We propose to adopt a new
airworthiness directive (AD) for all
CFM56–3 and CFM56–7B series
turbofan engines with certain accessory
gearboxes (AGBs) not equipped with a
handcranking pad ‘‘oil dynamic seal’’
assembly. This proposed AD was
prompted by 42 events of total loss of
engine oil from CFM56 series turbofan
engines while in flight. This proposed
AD would require an independent
inspection to verify re-installation of the
handcranking pad cover after removal of
the pad cover for maintenance until
installation of a handcranking pad oil
dynamic seal assembly. This inspection
requirement exceeds normal
maintenance and is necessary due to the
design and location of the handcranking
pad cover on the accessory gear box. We
are proposing this AD to prevent loss of
engine oil while in flight, which could
result in engine failure, loss of thrust
control, and damage to the airplane.
DATES: We must receive comments on
this proposed AD by August 9, 2013.
ADDRESSES: You may send comments,

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–
2013–0407; Directorate Identifier 2012–
NE–22–AD’’ at the beginning of your

comments on the overall regulatory,
economic, environmental, and energy
aspects of this proposed AD. We will

Discussion
We have received reports of 42
incidents of total loss of engine oil from
engines while in flight. Thirty-four
incidents were single-engine events and
resulted in an in-flight shutdown of the
engine or an air turnback (ATB). Four
incidents involved total loss of engine
oil in both engines installed on dualengine airplanes, which caused an
immediate ATB of the airplane. The loss
of engine oil was traced to the AGB
handcranking pad cover, which had not
been reinstalled after maintenance, for
example, after a borescope inspection of
the engine.
This proposed AD would require an
independent inspection of the AGB
handcranking pad cover to verify its reinstallation after removal. This
inspection requirement exceeds normal
maintenance and is necessary due to the
design and location of the handcranking
pad on the AGB. If an operator’s
approved maintenance program
includes an independent inspection of
the AGB handcranking pad cover after
removal then compliance with those
procedures will constitute compliance
to the inspection requirements of the
AD. This condition, if not corrected,
could result in loss of engine oil in
flight, which could lead to engine
failure, loss of thrust control, and
damage to the airplane.
FAA’s Determination
We are proposing this AD because we
evaluated all the relevant information
and determined the unsafe condition
PO 00000
Frm 00018
Fmt 4702
Sfmt 4702
described previously is likely to exist or
develop in other products of the same
type design.
Proposed AD Requirements
This proposed AD would require an
independent inspection to verify correct
installation of the handcranking pad
cover after removal of the pad cover for
maintenance. Introduction of a
handcranking pad oil dynamic seal is
available as an optional terminating
action to the repetitive inspection
requirements of this AD.
Costs of Compliance
We estimate that this proposed AD
would affect 2,702 CFM56–3 and
CFM56–7B engines installed on
airplanes of U.S. registry. We also
estimate that it would take about 1 hour
to perform the independent inspection
required by this AD. The average labor
rate is $85 per hour. We estimate that
normal maintenance will require the
AGB handcranking pad cover to be
removed every 1,300 flights cycles.
Based on an average use of these model
engines of approximately 6,000,000
flight cycles per year, we estimate that
an independent inspection would be
required approximately 4,615 times per
year. Therefore, assuming that an
operator does not already have an
independent inspection of the AGB
handcranking pad cover in its approved
maintenance program, we estimate the
cost of the proposed AD for U.S.
operators to be $392,275.
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
E:\FR\FM\10JNP1.SGM
10JNP1
Federal Register / Vol. 78, No. 111 / Monday, June 10, 2013 / Proposed Rules
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.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all
CFM56-3 and CFM56-7B series turbofan engines with certain accessory
gearboxes (AGBs) not equipped with a handcranking pad ``oil dynamic
seal'' assembly. This proposed AD was prompted by 42 events of total
loss of engine oil from CFM56 series turbofan engines while in flight.
This proposed AD would require an independent inspection to verify re-
installation of the handcranking pad cover after removal of the pad
cover for maintenance until installation of a handcranking pad oil
dynamic seal assembly. This inspection requirement exceeds normal
maintenance and is necessary due to the design and location of the
handcranking pad cover on the accessory gear box. We are proposing this
AD to prevent loss of engine oil while in flight, which could result in
engine failure, loss of thrust control, and damage to the airplane.

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
[[Page 34607]]
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.
