ACTION: Final rule. SUMMARY: We are superseding an existing airworthiness directive (AD) for 16:13 Sep 08, 2009 Jkt 217001 A recent design review has been carried out on the F28 Mark 0070/0100 fuel system in accordance with the guidelines related to FAA SFAR 88 [Special Federal Aviation Regulation No. 88] (Fuel Tank Safety Program) and JAA [Joint Aviation Authorities] INT/POL/25/12. The review revealed that under certain failure conditions, prolonged dry running of the fuel transfer pumps may result in an ignition source in the centre wing fuel tank. This condition, if not corrected, could lead to ignition of flammable fuel vapors, resulting in fuel tank explosion and consequent loss of the aircraft. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective October 14, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 14, 2009. On October 27, 1999 (64 FR 51202, September 22, 1999), the Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC.

SUPPLEMENTARY INFORMATION: Discussion RIN 2120–AA64 VerDate Nov<24>2008 the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated 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: 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 June 19, 2009 (74 FR 29144), and proposed to supersede AD 99–20– 01, Amendment 39–11329 (64 FR 51202, September 22, 1999). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 46319 A recent design review has been carried out on the F28 Mark 0070/0100 fuel system in accordance with the guidelines related to FAA SFAR 88 [Special Federal Aviation Regulation No. 88] (Fuel Tank Safety Program) and JAA [Joint Aviation Authorities] INT/POL/25/12. The review revealed that under certain failure conditions, prolonged dry running of the fuel transfer pumps may result in an ignition source in the centre wing fuel tank. This condition, if not corrected, could lead to ignition of flammable fuel vapors, resulting in fuel tank explosion and consequent loss of the aircraft. To address and correct this unsafe condition, new software (version V13.55) has been developed for the Flight Warning Computer (FWC). This software update introduces a decreased time delay of the centre wing fuel tank low pressure alert from 15 minutes to 60 seconds, to stop prolonged dry running of the fuel transfer pumps. For the reasons described above, this EASA Airworthiness Directive (AD) requires the replacement of the FWC with a modified unit, incorporating software version V13.55. The corrective actions include revising the airplane flight manual (AFM) to change certain indications and warnings; installing new software for the multifunction display unit (MFDU); and installing a new resistor in the thrust reverser indicator and control system, or an improved thrust reverser unlock indication relay. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a note within the AD. E:\FR\FM\09SER1.SGM 09SER1 46320 Federal Register / Vol. 74, No. 173 / Wednesday, September 9, 2009 / Rules and Regulations Costs of Compliance We estimate that this AD affects about 4 products of U.S. registry. The actions that are required by AD 99–20–01 and retained in this AD take about 7 work-hours per product, at an average labor rate of $80 per work hour. Required parts cost about $1,593 per product. Based on these figures, the estimated cost of the currently required actions is $2,153 per product. We estimate that it takes about 7 work-hours per product to comply with the new basic requirements of this AD. The average labor rate is $80 per workhour. Required parts cost about $5,350 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to U.S. operators to be $23,640, or $5,910 per product. 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. jlentini on DSKJ8SOYB1PROD with RULES Regulatory Findings We 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 this AD: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; VerDate Nov<24>2008 16:13 Sep 08, 2009 Jkt 217001 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. through 11537 inclusive, 11545, 11547, 11553, 11557, 11561, 11562, 11566, 11567, 11571, 11572, 11576 through 11579 inclusive, and 11581 through 11583 inclusive. All airplanes with these serial numbers are fitted with center wing fuel tanks. 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 the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt. Reason (e) The mandatory continuing airworthiness information (MCAI) states: A recent design review has been carried out on the F28 Mark 0070/0100 fuel system in accordance with the guidelines related to FAA SFAR 88 [Special Federal Aviation Regulation No. 88] (Fuel Tank Safety Program) and JAA [Joint Aviation Authorities] INT/POL/25/12. The review revealed that under certain failure conditions, prolonged dry running of the fuel transfer pumps may result in an ignition source in the centre wing fuel tank. This condition, if not corrected, could lead to ignition of flammable fuel vapors, resulting in fuel tank explosion and consequent loss of the aircraft. To address and correct this unsafe condition, new software (version V13.55) has been developed for the Flight Warning Computer (FWC). This software update introduces a decreased time delay of the centre wing fuel tank low pressure alert from 15 minutes to 60 seconds, to stop prolonged dry running of the fuel transfer pumps. For the reasons described above, this EASA Airworthiness Directive (AD) requires the replacement of the FWC with a modified unit, incorporating software version V13.55. The corrective actions include revising the airplane flight manual (AFM) to change certain indications and warnings; installing new software for the multifunction display unit (MFDU); and installing a new resistor in the thrust reverser indicator and control system, or an improved thrust reverser unlock indication relay.

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) originated 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: An A340 operator has reported an uncommanded engine N°4 shut down during taxi after landing. The root cause of this event has been identified as failure of the fuel pump Non Return Valve (NRV) preventing the collector cell jet pump from working. This led to engine N°4 collector cell fuel level to drop below the pump inlet and consequently causing engine N°4 flame out. * * * * * Multiple NRV failures in combination with failure modes trapping fuel could potentially PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 Date increase the quantity of unusable fuel on aircraft possibly leading to fuel starvation which could result in engine in-flight shut down and would constitute an unsafe condition. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective October 14, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of October 14, 2009. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC.

Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for the products listed above. This AD results from mandatory 
continuing airworthiness information (MCAI) originated 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:

    A recent design review has been carried out on the F28 Mark 
0070/0100 fuel system in accordance with the guidelines related to 
FAA SFAR 88 [Special Federal Aviation Regulation No. 88] (Fuel Tank 
Safety Program) and JAA [Joint Aviation Authorities] INT/POL/25/12. 
The review revealed that under certain failure conditions, prolonged 
dry running of the fuel transfer pumps may result in an ignition 
source in the centre wing fuel tank. This condition, if not 
corrected, could lead to ignition of flammable fuel vapors, 
resulting in fuel tank explosion and consequent loss of the 
aircraft.
* * * * *
    We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective October 14, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 14, 
2009.
    On October 27, 1999 (64 FR 51202, September 22, 1999), the Director 
of the Federal Register approved the incorporation by reference of 
certain other publications listed in this AD.

ADDRESSES: You may examine the AD docket on the Internet at https://www.regulations.gov or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC.

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 June 19, 2009 (74 FR 
29144), and proposed to supersede AD 99-20-01, Amendment 39-11329 (64 
FR 51202, September 22, 1999). That NPRM proposed to correct an unsafe 
condition for the specified products. The MCAI states:

    A recent design review has been carried out on the F28 Mark 
0070/0100 fuel system in accordance with the guidelines related to 
FAA SFAR 88 [Special Federal Aviation Regulation No. 88] (Fuel Tank 
Safety Program) and JAA [Joint Aviation Authorities] INT/POL/25/12. 
The review revealed that under certain failure conditions, prolonged 
dry running of the fuel transfer pumps may result in an ignition 
source in the centre wing fuel tank. This condition, if not 
corrected, could lead to ignition of flammable fuel vapors, 
resulting in fuel tank explosion and consequent loss of the 
aircraft.
    To address and correct this unsafe condition, new software 
(version V13.55) has been developed for the Flight Warning Computer 
(FWC). This software update introduces a decreased time delay of the 
centre wing fuel tank low pressure alert from 15 minutes to 60 
seconds, to stop prolonged dry running of the fuel transfer pumps.
    For the reasons described above, this EASA Airworthiness 
Directive (AD) requires the replacement of the FWC with a modified 
unit, incorporating software version V13.55.

    The corrective actions include revising the airplane flight manual 
(AFM) to change certain indications and warnings; installing new 
software for the multifunction display unit (MFDU); and installing a 
new resistor in the thrust reverser indicator and control system, or an 
improved thrust reverser unlock indication relay. You may obtain 
further information by examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a note within the AD.

[[Page 46320]]

Costs of Compliance

    We estimate that this AD affects about 4 products of U.S. registry.
    The actions that are required by AD 99-20-01 and retained in this 
AD take about 7 work-hours per product, at an average labor rate of $80 
per work hour. Required parts cost about $1,593 per product. Based on 
these figures, the estimated cost of the currently required actions is 
$2,153 per product.
    We estimate that it takes about 7 work-hours per product to comply 
with the new basic requirements of this AD. The average labor rate is 
$80 per work-hour. Required parts cost about $5,350 per product. Where 
the service information lists required parts costs that are covered 
under warranty, we have assumed that there will be no charge for these 
costs. As we do not control warranty coverage for affected parties, 
some parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of this AD to U.S. operators to be 
$23,640, or $5,910 per product.

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

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 the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

numbers are fitted with center wing fuel tanks.

Subject

    (d) Air Transport Association (ATA) of America Codes 31 and 78: 
Instruments and Engine Exhaust, respectively.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    A recent design review has been carried out on the F28 Mark 
0070/0100 fuel system in accordance with the guidelines related to 
FAA SFAR 88 [Special Federal Aviation Regulation No. 88] (Fuel Tank 
Safety Program) and JAA [Joint Aviation Authorities] INT/POL/25/12. 
The review revealed that under certain failure conditions, prolonged 
dry running of the fuel transfer pumps may result in an ignition 
source in the centre wing fuel tank. This condition, if not 
corrected, could lead to ignition of flammable fuel vapors, 
resulting in fuel tank explosion and consequent loss of the 
aircraft.
    To address and correct this unsafe condition, new software 
(version V13.55) has been developed for the Flight Warning Computer 
(FWC). This software update introduces a decreased time delay of the 
centre wing fuel tank low pressure alert from 15 minutes to 60 
seconds, to stop prolonged dry running of the fuel transfer pumps.
    For the reasons described above, this EASA Airworthiness 
Directive (AD) requires the replacement of the FWC with a modified 
unit, incorporating software version V13.55.
    The corrective actions include revising the airplane flight 
manual (AFM) to change certain indications and warnings; installing 
new software for the multifunction display unit (MFDU); and 
installing a new resistor in the thrust reverser indicator and 
control system, or an improved thrust reverser unlock indication 
relay.

Restatement of Requirements of AD 99-20-01 With No Changes to the 
Modifications

    (f) Unless already done, within 18 months after October 27, 1999 
(the effective date of AD 99-20-01), modify the electrical wiring of 
the FWC in accordance with Part 1 or 2, as applicable, of the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-31-
047, Revision 1, dated March 21, 1997.

    Note 1: It is not necessary to install computer software version 
V10.40 into the FWC, since a later version is available and is 
required to be installed by AD 99-20-01.

    (g) Unless already done, concurrently with the accomplishment of 
the requirements of paragraph (f) of this AD, install upgraded 
computer software version V11.45 into the FWC in accordance with 
Fokker Service Bulletin SBF100-31-051, dated August 15, 1998.

    Note 2: AlliedSignal Grimes Aerospace has issued Service 
Bulletin 80-0610-31-0031, dated May 14, 1998, as an additional 
source

[[Page 46321]]

of guidance for installation of the upgraded computer software 
version into the FWC.


    Note 3: Operators should note that Fokker Service Bulletin 
SBF100-31-051, dated August 15, 1998, specifies prior or concurrent 
accomplishment of Fokker Service Bulletin SBF100-78-014 (which 
specifies concurrent accomplishment of Fokker Component Service 
Bulletin (CSB) P41440-78-04, and prior or concurrent accomplishment 
of Fokker Service Bulletin SBF100-78-012 and CSB P41440-78-05). 
Related FAA AD 99-20-02, amendment 39-11330, requires accomplishment 
of these four other service bulletins.

New Requirements of This AD: Actions and Compliance

    (h) Unless already done, do the following actions.
    (1) Within 36 months after the effective date of this AD, 
replace FWC units having part number (P/N) 80-0610-3-45 and P/N 80-
0610-3-50 with modified units having P/N 80-0610-3-55, in accordance 
with the Accomplishment Instructions of Fokker Service Bulletin 
SBF100-31-067, Revision 1, dated April 24, 2008.
    (2) Within 36 months after the effective date of this AD and 
concurrently with the accomplishment of paragraph (h)(1) of this AD, 
revise the Emergency and Abnormal Procedures sections of the 
airplane flight manual (AFM), as specified in Fokker Manual Change

alterations, which are introduced in Fokker Service Bulletin SBF100-
31-067, Revision 1, dated April 24, 2008.

    Note 4: Revisions to the Emergency Procedures and Abnormal 
Procedures sections of the AFM, as specified in Fokker MCNO-F100-
050, dated January 31, 2008, may be done by inserting copies of 
Fokker MCNO-F100-050, dated January 31, 2008, into the AFM. When the 
information in Fokker MCNO-F100-050, dated January 31, 2008, has 
been included in general revisions of the AFM, the general revisions 
may be inserted in the AFM, provided the relevant information in the 
general revisions are identical to that in Fokker MCNO-F100-050, 
dated January 31, 2008.

    (3) After accomplishing paragraph (h)(1) of this AD, no person 
may install an FWC having P/N 80-0610-3-45 or P/N 80-0610-3-50, 
unless it has been modified to P/N 80-0610-3-55 standard in 
accordance with Honeywell Service Bulletin 80-0610-31-0003, dated 
February 13, 2008.
    (4) Within 36 months after the effective date of this AD, 
install software version V12 for the MFDU in accordance with the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-31-
060, dated June 1, 2002.
    (5) Within 36 months after the effective date of this AD, modify 
the thrust reverser indication and control system in accordance with 
the Accomplishment Instructions of Fokker Service Bulletin SBF100-

indication relay in accordance with the Accomplishment Instructions 
of Fokker Service Bulletin SBF100-78-017, dated December 1, 1999.

FAA AD Differences

    Note 5: This AD differs from the MCAI and/or service information 
as follows:
    (1) Replacing the MFDU in accordance with Fokker Service 
Bulletin SBF100-31-060, dated June 1, 2002, is not included in the 
MCAI; however, this AD includes that action. It is necessary to 
install a new version of the MFDU software before installing the new 
version of the FWC software.
    (2) Modifying the thrust reverser indication and control system 
in accordance with Fokker Service Bulletin SBF100-78-016, dated 
October 1, 1999; or modifying the thrust reverser unlock indication 
relay in accordance with Fokker Service Bulletin SBF100-78-017, 
dated December 1, 1999, is not included in the MCAI; however, this 
AD includes those actions. It is necessary to do one of those 
actions before installing the MFDU software.
