ACTION: Final rule; request for comments. SUMMARY: The FAA is revising an existing airworthiness directive (AD), which applies to all Airbus Model A318–111 and –112 series airplanes, and all Model A319, A320, and A321 series airplanes. That AD currently requires revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness to PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 62219 incorporate new limitations for fuel tank systems. This AD clarifies the intended effect of the AD on spare and onairplane fuel tank system components. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. DATES: This AD is effective December 14, 2009. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of December 14, 2009. On August 28, 2007 (72 FR 40222, July 24, 2007), the Director of the Federal Register approved the incorporation by reference of certain other publications listed in the AD.

FOR FURTHER INFORMATION CONTACT: Tim Dulin, Aerospace Engineer, E:\FR\FM\27NOR1.SGM 27NOR1 62220 Federal Register / Vol. 74, No. 227 / Friday, November 27, 2009 / Rules and Regulations International Branch, ANM–116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057–3356; telephone (425) 227–2141; fax (425) 227–1149. SUPPLEMENTARY INFORMATION: Discussion On July 13, 2007, we issued AD 2007– 15–06, Amendment 39–15135 (72 FR 40222, July 24, 2007). That AD applied to all Airbus Model A318–111 and –112 series airplanes, and all A319, A320, and A321 series airplanes. That AD required revising the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness to incorporate new limitations for fuel tank systems. Critical design configuration control limitations (CDCCLs) are limitation requirements to preserve a critical ignition source prevention feature of the fuel tank system design that is necessary to prevent the occurrence of an unsafe condition. The purpose of a CDCCL is to provide instruction to retain the critical ignition source prevention feature during configuration change that may be caused by alterations, repairs, or maintenance actions. A CDCCL is not a periodic inspection. Actions Since AD was Issued Since we issued that AD, we have determined that it is necessary to clarify the AD’s intended effect on spare and on-airplane fuel tank system components, regarding the use of maintenance manuals and instructions for continued airworthiness. Section 91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)) specifies the following: srobinson on DSKHWCL6B1PROD with RULES No person may operate an aircraft for which a manufacturer’s maintenance manual or instructions for continued airworthiness has been issued that contains an airworthiness limitation section unless the mandatory * * * procedures * * * have been complied with. Some operators have questioned whether existing components affected by the new CDCCLs must be reworked. We did not intend for the AD to retroactively require rework of components that had been maintained using acceptable methods before the effective date of the AD. Owners and operators of the affected airplanes therefore are not required to rework affected components identified as airworthy or installed on the affected airplanes before the required revisions of the ALS. But once the CDCCLs are incorporated into the ALS, future maintenance actions on components must be done in accordance with those CDCCLs. VerDate Nov<24>2008 16:26 Nov 25, 2009 Jkt 220001 Relevant Service Information AD 2007–15–06 cites Airbus A318/ A319/A320/A321 Fuel Airworthiness Limitations, Document 95A.1931/05, Issue 1, dated December 19, 2005; and Airbus A318/A319/A320/A321 ALS Part 5—Fuel Airworthiness Limitations, dated February 28, 2006. Since we issued that AD, Airbus has revised the referenced service information and issued Airbus A318/A319/A320/A321 Fuel Airworthiness Limitations, Document 95A.1931/05, Issue 2, dated July 8, 2008. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This AD The affected product(s) have been approved by the aviation authority of another country, and are approved for operation in the United States. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This new AD retains the requirements of the existing AD, and adds a new note to clarify the intended effect of the AD on spare and on-airplane fuel tank system components. Costs of Compliance Based on the service information, we estimate that this AD would affect about 720 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of the AD on U.S. operators to be $115,200, or $160 per product. FAA’s Justification and Determination of the Effective Date This revision merely clarifies the intended effect on spare and on-airplane fuel tank system components, and makes no substantive change to the AD’s requirements. For this reason, it is found that notice and opportunity for prior public comment for this action are unnecessary, and 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 we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2009–1073; Directorate Identifier 2009– NM–174–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. 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 regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

ACTION: Final rule. SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: VerDate Nov<24>2008 16:26 Nov 25, 2009 Jkt 220001 Under certain ambient conditions, ice can accumulate on the walls of the fuel pipes within the aircraft fuel system, which can then be released downstream when fuel flow demand is increased. This released ice can then collect on the fuel-to-oil heat exchanger (FOHE) front face and limit fuel flow through the FOHE. We are issuing this AD to prevent ice from blocking the FOHE, which could result in an unacceptable engine power loss, and loss of control of the airplane. DATES: This AD becomes effective January 4, 2010. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of January 4, 2010. ADDRESSES: The Docket Operations office is located at Docket Management Facility, U.S. Department of Transportation, 1200 New Jersey Avenue, SE., West Building Ground Floor, Room W12–140, Washington, DC 20590–0001.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on July 23, 2009 (74 FR 36422). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: This Airworthiness Directive has been raised following an incident involving dual loss of engine response in the final stages of approach leading to touchdown short of the runway. The phenomenon involved in the loss of engine response has also been seen in flight affecting just one engine. Post incident analysis and investigation has established that, under certain ambient conditions, ice can accumulate on the walls of the fuel pipes within the aircraft fuel system, which can then be released downstream when fuel flow demand is increased. This released ice can then collect on the FOHE front face and limit fuel flow through the FOHE. This type of icing event was previously unknown and creates ice concentrations in the fuel system beyond those specified in the certification requirements. PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 To mitigate the risk of engine FOHE blockage, this AD requires replacing the FOHE, part number (P/N) 55003001–1 or 55003001–11, with a FOHE that has been modified using Rolls-Royce plc Alert Service Bulletin (ASB) No. RB.211–79–AG257, Revision 1, dated September 14, 2009. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Eliminate ‘‘Or Equivalent’’ From Paragraph (e) Delta Airlines requests that we eliminate the words ‘‘or equivalent’’ from paragraph (e) of the proposed AD. We agree. We deleted them from paragraph (e) of the AD.

Airplanes, and Model A319, A320, and A321 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: The FAA is revising an existing airworthiness directive (AD), 
which applies to all Airbus Model A318-111 and -112 series airplanes, 
and all Model A319, A320, and A321 series airplanes. That AD currently 
requires revising the Airworthiness Limitations section of the 
Instructions for Continued Airworthiness to incorporate new limitations 
for fuel tank systems. This AD clarifies the intended effect of the AD 
on spare and on-airplane fuel tank system components. This AD results 
from fuel system reviews conducted by the manufacturer. We are issuing 
this AD to prevent the potential of ignition sources inside fuel tanks, 
which, in combination with flammable fuel vapors, could result in a 
fuel tank explosion and consequent loss of the airplane.

SUPPLEMENTARY INFORMATION: 

Discussion

    On July 13, 2007, we issued AD 2007-15-06, Amendment 39-15135 (72 
FR 40222, July 24, 2007). That AD applied to all Airbus Model A318-111 
and -112 series airplanes, and all A319, A320, and A321 series 
airplanes. That AD required revising the Airworthiness Limitations 
section (ALS) of the Instructions for Continued Airworthiness to 
incorporate new limitations for fuel tank systems.
    Critical design configuration control limitations (CDCCLs) are 
limitation requirements to preserve a critical ignition source 
prevention feature of the fuel tank system design that is necessary to 
prevent the occurrence of an unsafe condition. The purpose of a CDCCL 
is to provide instruction to retain the critical ignition source 
prevention feature during configuration change that may be caused by 
alterations, repairs, or maintenance actions. A CDCCL is not a periodic 
inspection.

Actions Since AD was Issued

    Since we issued that AD, we have determined that it is necessary to 
clarify the AD's intended effect on spare and on-airplane fuel tank 
system components, regarding the use of maintenance manuals and 
instructions for continued airworthiness.
    Section 91.403(c) of the Federal Aviation Regulations (14 CFR 
91.403(c)) specifies the following:

    No person may operate an aircraft for which a manufacturer's 
maintenance manual or instructions for continued airworthiness has 
been issued that contains an airworthiness limitation section unless 
the mandatory * * * procedures * * * have been complied with.

    Some operators have questioned whether existing components affected 
by the new CDCCLs must be reworked. We did not intend for the AD to 
retroactively require rework of components that had been maintained 
using acceptable methods before the effective date of the AD. Owners 
and operators of the affected airplanes therefore are not required to 
rework affected components identified as airworthy or installed on the 
affected airplanes before the required revisions of the ALS. But once 
the CDCCLs are incorporated into the ALS, future maintenance actions on 
components must be done in accordance with those CDCCLs.

Relevant Service Information

    AD 2007-15-06 cites Airbus A318/A319/A320/A321 Fuel Airworthiness 
Limitations, Document 95A.1931/05, Issue 1, dated December 19, 2005; 
and Airbus A318/A319/A320/A321 ALS Part 5--Fuel Airworthiness 
Limitations, dated February 28, 2006. Since we issued that AD, Airbus 
has revised the referenced service information and issued Airbus A318/
A319/A320/A321 Fuel Airworthiness Limitations, Document 95A.1931/05, 
Issue 2, dated July 8, 2008. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of This AD

    The affected product(s) have been approved by the aviation 
authority of another country, and are approved for operation in the 
United States. We are issuing this AD because we evaluated all 
pertinent information and determined the unsafe condition exists and is 
likely to exist or develop on other products of the same type design. 
This new AD retains the requirements of the existing AD, and adds a new 
note to clarify the intended effect of the AD on spare and on-airplane 
fuel tank system components.

Costs of Compliance

    Based on the service information, we estimate that this AD would 
affect about 720 products of U.S. registry. We also estimate that it 
would take about 2 work-hours per product to comply with the basic 
requirements of this AD. The average labor rate is $80 per work-hour. 
Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $115,200, or $160 per product.

FAA's Justification and Determination of the Effective Date

    This revision merely clarifies the intended effect on spare and on-
airplane fuel tank system components, and makes no substantive change 
to the AD's requirements. For this reason, it is found that notice and 
opportunity for prior public comment for this action are unnecessary, 
and 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 we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2009-1073; Directorate Identifier 2009-NM-174-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

    Note 1: This AD requires revisions to certain operator 
maintenance documents to include new inspections and critical design 
configuration control limitations (CDCCLs). Compliance with the 
operator maintenance documents is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired 
in the areas addressed by these inspections and CDCCLs, the operator 
may not be able to accomplish inspections and CDCCLs described in 
the revisions. In this situation, to comply with 14 CFR 91.403(c), 
the operator must request approval for an alternative method of 
compliance according to paragraph (i) of this AD. The request should 
include a description of changes to the required inspections and 
CDCCLs that will preserve the critical ignition source prevention 
feature of the affected fuel system.

Unsafe Condition

    (d) This AD results from fuel system reviews conducted by the 
manufacturer. We are issuing this AD to prevent the potential of 
ignition sources inside fuel tanks, which, in combination with 
flammable fuel vapors, could result in a fuel tank explosion and 
consequent loss of the airplane.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.
