SUPPLEMENTARY INFORMATION: We have received reports of 12 PMA fuel filters, fuel filters part numbers WF337661 and WF337017, manufactured by Western Filter, and part numbers 7595983–101 and 7588133, manufactured by PTI Technologies, that have failed in service on CFM56–7B engines since March 2006. These filters use a deeper pleat and are more susceptible to collapse or deterioration of the filter media than the original equipment manufacturer filters. A collapsed or deteriorated fuel filter can allow unfiltered fuel contamination in fuel components, including fuel nozzles, with no indication of fuel filter bypass to the flight crew. This condition, if not corrected, could result in the loss of engine thrust that could result in loss of control during takeoff or landing. The unsafe condition described previously is likely to exist or develop on other CFM International CFM56 series engines of the same type design.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain CFM International CFM56 Series turbofan engines. This AD 
requires replacing certain fuel filters manufactured under parts 
manufacturer approvals (PMA). This AD results from 12 reports of failed 
fuel filters. We are issuing this AD to prevent the loss of engine 
thrust that could result in loss of control during takeoff or landing.

DATES: This AD becomes effective January 3, 2007.
    We must receive any comments on this AD by February 20, 2007.

SUPPLEMENTARY INFORMATION: We have received reports of 12 PMA fuel 
filters, fuel filters part numbers WF337661 and WF337017, manufactured 
by Western Filter, and part numbers 7595983-101 and 7588133, 
manufactured by PTI Technologies, that have failed in service on CFM56-
7B engines since March 2006. These filters use a deeper pleat and are 
more susceptible to collapse or deterioration of the filter media than 
the original equipment manufacturer filters. A collapsed or 
deteriorated fuel filter can allow unfiltered fuel contamination in 
fuel components, including fuel nozzles, with no indication of fuel 
filter bypass to the flight crew. This condition, if not corrected, 
could result in the loss of engine thrust that could result in loss of 
control during takeoff 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 CFM56 series engines of the same 
type design. For that reason, we are issuing this AD to prevent the 
potential loss of thrust that could result in loss of control during 
takeoff or landing.

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.

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-2006-26502; 
Directorate Identifier 2006-NE-37-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://
dms.dot.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 DMS Web 
site, anyone can find and read the comments in any of our dockets, 
including the name of the individual who sent the comment (or signed 
the comment on behalf of an association, business, labor union, etc.).

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 the 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); 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.
