We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this proposed AD. Discussion We have received reports over the past 18 months of CFM model CFM56– 5 and CFM56–5B series turbofan engines, when operated on type TS–1 fuel, that have experienced an in-flight shutdown resulting from HMU failures. Investigation has determined that these HMU failures were caused by corrosion and seizure of the HMU delta P valve. Fuel samples from event airplanes also contained contaminants and corrosive catalysts. This condition, if not corrected, could result in seizure of the HMU, leading to failure of one or more engines and damage to the airplane. Relevant Service Information We reviewed CFM Service Bulletin (SB) CFM56–5 S/B 73–0182, Revision 7, dated September 25, 2012, and CFM SB CFM56–5B S/B 73–0122, Revision 9, dated September 25, 2012. The service information describes procedures for cleaning, inspection, and repair of the affected HMUs. FAA’s Determination We are issuing this proposed AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist in other products of the same type design. Proposed AD Requirements This proposed AD would require removing, cleaning, inspection, and repair of the affected HMUs. srobinson on DSK4SPTVN1PROD with Based on the service information, we estimate that this proposed AD would not affect any products of U.S. registry. We also estimate that it would take about 4 hours per engine to comply with this proposed AD. The average labor rate is $85 per hour. Based on these 16:19 Jan 11, 2013 Jkt 229001 PART 39—AIRWORTHINESS DIRECTIVES 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, 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.

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) model CFM56-5 and CFM56-5B 
series turbofan engines. This proposed AD was prompted by corrosion of 
the delta P valve in the hydromechanical unit (HMU) caused by 
contaminants in type TS-1 fuel. This proposed AD would require 
cleaning, inspection and repair of affected HMUs. We are proposing this 
AD to prevent seizure of the HMU, leading to failure of one or more 
engines and damage to the airplane.

DATES: We must receive comments on this proposed AD by March 15, 2013.

this proposed AD. Send your comments to an address listed under the 
ADDRESSES section. Include ``Docket No. FAA-2012-1114; Directorate 
Identifier 2012-NE-21-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 based on those comments.
    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 proposed AD.

Discussion

    We have received reports over the past 18 months of CFM model 
CFM56-5 and CFM56-5B series turbofan engines, when operated on type TS-
1 fuel, that have experienced an in-flight shutdown resulting from HMU 
failures. Investigation has determined that these HMU failures were 
caused by corrosion and seizure of the HMU delta P valve. Fuel samples 
from event airplanes also contained contaminants and corrosive 
catalysts. This condition, if not corrected, could result in seizure of 
the HMU, leading to failure of one or more engines and damage to the 
airplane.

Relevant Service Information

    We reviewed CFM Service Bulletin (SB) CFM56-5 S/B 73-0182, Revision 
7, dated September 25, 2012, and CFM SB CFM56-5B S/B 73-0122, Revision 
9, dated September 25, 2012. The service information describes 
procedures for cleaning, inspection, and repair of the affected HMUs.

FAA's Determination

    We are issuing this proposed AD because we evaluated all the 
relevant information and determined the unsafe condition described 
previously is likely to exist in other products of the same type 
design.

Proposed AD Requirements

    This proposed AD would require removing, cleaning, inspection, and 
repair of the affected HMUs.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would not affect any products of U.S. registry. We also estimate that 
it would take about 4 hours per engine to comply with this proposed AD. 
The average labor rate is $85 per hour. Based on these figures, we 
estimate the proposed AD to have no cost impact to U.S. operators.

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, 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.

CFM International S.A.: Docket No. FAA-2012-1114; Directorate 
Identifier 2012-NE-21-AD.

(a) Comments Due Date

    We must receive comments by March 15, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to CFM International S.A. (CFM) CFM56-5 and 
CFM56-5B series turbofan engines with any of the hydromechanical 
unit (HMU) fuel control part numbers (P/Ns) in paragraphs (c)(1) and 
(c)(2) of this AD, installed:
    (1) CFM56-5: CFM P/Ns 1348M79P02; 1348M79P03; 1348M79P04; 
1348M79P06; 1348M79P07; 1348M79P08; 1348M79P09; 1348M79P10; 
1348M79P11; 1348M79P12; 1348M79P13; and 1348M79P14.
    (2) CFM56-5B: CFM P/Ns: 1348M79P08; 1348M79P09; 1348M79P10; 
1348M79P11; 1348M79P12; 1348M79P13; and 1348M79P14.

(d) Unsafe Condition

    This AD was prompted by corrosion of the delta P valve in the 
HMU fuel control caused by exposure to type TS-1 fuel. We are 
issuing this AD to prevent seizure of the HMU, leading to failure of 
one or more engines and damage to the airplane.

(e) Compliance

    Unless already done, do the following:

(f) Record Type TS-1 Fuel Usage

    (1) From the effective date of this AD, record all TS-1 fuel 
usage.
    (2) If the HMU never uses TS-1 fuel, no further action is 
required.

(g) Initial Inspection

    If the HMU has operated on TS-1 fuel, inspect the HMU for 
corrosion as follows:
    (1) For an HMU that has operated for less than 8,000 hours since 
new (HSN) or hours since last overhaul, inspect the HMU before 
10,000 HSN or hours since last overhaul, whichever comes later.
    (2) For an HMU that has operated for 8,000 or more HSN or hours 
since last overhaul, inspect the HMU within 24 months or 2,000 hours 
after the effective date of this AD, whichever comes first.
    (3) Use paragraph 3.A(2) of CFM Service Bulletin (SB) CFM56-5 S/
B 73-0182, Revision 7, dated September 25, 2012, or CFM SB CFM56-5B 
S/B 73-0122, Revision 9, dated September 25, 2012, to do the 
inspection.

(h) Repetitive Inspections

    Repeat the inspection required in paragraph (g)(3) of this AD 
before 10,000 hours since last overhaul if after last overhaul the 
HMU is exposed to TS-1 fuel.

(i) Paperwork Reduction Act Burden Statement

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty 
for failure to comply with a collection of information subject to 
the requirements of the Paperwork Reduction Act unless that 
collection of information displays a current valid OMB Control 
Number. The OMB Control Number for this information collection is
