This AD requires adding two new indicator lights on a certain panel to inform the captain and SUMMARY: VerDate Mar<15>2010 16:09 Dec 15, 2010 Jkt 223001 first officer of a low pressure condition in the left and right override/jettison pumps of the center wing tanks. This AD also requires replacing the left and right override/jettison switches on the M154 fuel control module on the P4 panel with improved switches and doing the associated wiring changes. This AD also requires, for certain airplanes, installation of a mounting bracket for the new indicator lights. This AD also requires a revision to the maintenance program to incorporate airworthiness limitation No. 28–AWL– 22. This AD also requires a revision to the airplane flight manual to advise the flightcrew what to do in the event that the pump low pressure light on the flight engineer’s panel does not illuminate when the pump is selected off. This AD was prompted by fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent uncommanded operation of the override/jettison pumps of the center wing tanks, and failure to manually shut off the override/jettison pumps at the correct time, either of which could lead to an ignition source inside the center wing tank. This condition, in combination with flammable fuel vapors, could result in a center fuel tank explosion and consequent loss of the airplane. This AD is effective January 20, 2011. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of January 20, 2011.

SUPPLEMENTARY INFORMATION: Discussion We issued a supplemental notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That supplemental NPRM published in the Federal Register on October 1, 2010 (75 FR 60661). That supplemental NPRM proposed to require adding two new indicator lights on the P10 panel to inform the captain and first officer of a low pressure condition in the left and right override/jettison pumps of the center wing tanks. That supplemental NPRM also proposed to require replacing the left and right override/ jettison switches on the M154 fuel control module on the P4 panel with improved switches and doing the associated wiring changes. That supplemental NPRM also proposed to require, for certain airplanes, installation of a mounting bracket for the new indicator lights. That supplemental NPRM also proposed to require a revision to the maintenance program to incorporate airworthiness E:\FR\FM\16DER1.SGM 16DER1 78592 Federal Register / Vol. 75, No. 241 / Thursday, December 16, 2010 / Rules and Regulations limitation No. 28–AWL–22. That supplemental NPRM also proposed to require a revision to the airplane flight manual to advise the flightcrew what to do in the event that the pump low pressure light on the flight engineer’s panel does not illuminate when the pump is selected off. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the supplemental NPRM or on the determination of the cost to the public. Clarification In our response in the supplemental NPRM to Northwest Airline’s Request to Reference Later Revision of Service Bulletin Cited in Original NPRM, we described some of the changes in Boeing Service Bulletin 747–28A2288, Revision 1, dated January 21, 2010. That service bulletin was described as having installation instructions for the LOW PRESS indicator lights for airplanes that did not have the warning panel (i.e., the P10 panel) installed. We also described the changes to paragraph (g) of the Supplemental NPRM. We have revised the Summary and paragraph (g) of this AD to clarify that both groups of airplanes, with or without the warning panel installed, must install the two new indicator lights on certain panels (either the P10 panel, or for those airplanes without the P10 panel installed, the Autopilot Flight Director panel). Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that this AD affects 185 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Labor cost Boeing Service Bulletin 747-28A2288, Revision 1. AFM revision .............. Between 30 and 32 work-hours × $85 per hour = Between $2,550 and $2,720. Between $2,768 and $2,868. Between $5,318 and $5,588. Between $983,830 and $1,033,780. 1 work-hour × $85 per hour = $85 ................. None .......................... $85 ............................. $15,725 jlentini on DSKJ8SOYB1PROD with RULES 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 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 this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, VerDate Mar<15>2010 16:09 Dec 15, 2010 Jkt 223001 Parts cost (2) Is not a ‘‘significant rule’’ under 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: ■ PART 39—AIRWORTHINESS DIRECTIVES 1.

This AD requires installing a new insulation blanket on the latch beam firewall of each thrust reverser (T/R) half. This AD results from an in-flight shutdown due to an engine fire indication; an undercowl engine fire was extinguished after landing. The cause of the fire was uncontained failure of the starter in the engine core compartment; the fire progressed into the latch beam cavity and was fueled by oil from a damaged integrated drive generator oil line. We are issuing this AD to prevent a fire from entering the cowl or strut area, which could weaken T/R parts and result in reduced structural integrity of the T/R, possible separation of T/R parts during flight, and consequent damage to the airplane and injury to people or damage to property on the ground.

Jkt 223001 We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Boeing Model 777–200 series airplanes. That NPRM was published in the Federal Register on May 7, 2009 (74 FR 21284). That NPRM proposed to require installing a new insulation blanket on the latch beam firewall of each thrust reverser (T/R) half. Relevant Service Information Since we issued the NPRM, we have reviewed Boeing Alert Service Bulletin 777–78A0066, Revision 2, dated April 8, 2010. Boeing Service Bulletin 777– 78A0066, Revision 1, dated March 12, 2009, was referred to in the original NPRM as the appropriate source of service information for accomplishing the proposed actions. No more work is necessary for airplanes on which Revision 1 of this service bulletin was used for doing the actions. Boeing Alert Service Bulletin 777–78A0066, Revision 2, dated April 8, 2010, moves certain PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 airplanes to Group 1, and contains minor editorial changes. We have revised paragraphs (c) and (g) of this AD to refer to Revision 2 of Boeing Alert Service Bulletin 777– 78A0066, Revision 2, dated April 8, 2010, and paragraph (h) to add credit for accomplishing the specified actions in accordance with Boeing Service Bulletin 777–78A0066, Revision 1, dated March 12, 2009. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Clarify Description of Unsafe Condition Boeing asked that we clarify the description of the unsafe condition by removing the words ‘‘or strut’’ from the identified description. Boeing stated that the unsafe condition, as currently written, is not correct. Boeing did not provide the reason that the description is not correct. We disagree that the description of the unsafe condition should be clarified by removing ‘‘or strut’’ from the description. A fire in the lower latch beam area that burns through an inadequate firewall may propagate into the strut. We have made no change to the AD in this regard. Request To Clarify Applicability Japan Airlines International (JALI) asked for clarification of the applicability specified in the NPRM. JALI stated that the applicability specifies Model 777–200 series airplanes identified in Boeing Service Bulletin 777–78A0066, Revision 1, dated March 12, 2009. JALI noted that the service bulletin specifies its effectivity as delivered condition, and the proposed rule is considered to be applicable to each T/R half that has been installed on airplanes with the applicable serial numbers. JALI added that the T/R half is a replaceable line unit and the installed airplane and/or engine position will be changed from the delivered condition in the future; the T/R half that is not necessary for doing the requirements in the NPRM may be installed on an airplane identified in the applicability. JALI stated that, in light of these factors, it is not clear whether compliance with the specified actions has been met. JALI asked that we clarify the applicability either to note that the NPRM does not apply to airplanes on which a T/R is installed with a design change known as ‘‘Commonality T/R,’’ which is common to Model 777–300 series airplanes, or to change the E:\FR\FM\16DER1.SGM 16DER1

products listed above. This AD requires adding two new indicator lights 
on a certain panel to inform the captain and first officer of a low 
pressure condition in the left and right override/jettison pumps of the 
center wing tanks. This AD also requires replacing the left and right 
override/jettison switches on the M154 fuel control module on the P4 
panel with improved switches and doing the associated wiring changes. 
This AD also requires, for certain airplanes, installation of a 
mounting bracket for the new indicator lights. This AD also requires a 
revision to the maintenance program to incorporate airworthiness 
limitation No. 28-AWL-22. This AD also requires a revision to the 
airplane flight manual to advise the flightcrew what to do in the event 
that the pump low pressure light on the flight engineer's panel does 
not illuminate when the pump is selected off. This AD was prompted by 
fuel system reviews conducted by the manufacturer. We are issuing this 
AD to prevent uncommanded operation of the override/jettison pumps of 
the center wing tanks, and failure to manually shut off the override/
jettison pumps at the correct time, either of which could lead to an 
ignition source inside the center wing tank. This condition, in 
combination with flammable fuel vapors, could result in a center fuel 
tank explosion and consequent loss of the airplane.

DATES: This AD is effective January 20, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of January 20, 
2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of June 
12, 2008 (73 FR 25977, May 8, 2008).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (NPRM) to 
amend 14 CFR part 39 to include an airworthiness directive (AD) that 
would apply to the specified products. That supplemental NPRM published 
in the Federal Register on October 1, 2010 (75 FR 60661). That 
supplemental NPRM proposed to require adding two new indicator lights 
on the P10 panel to inform the captain and first officer of a low 
pressure condition in the left and right override/jettison pumps of the 
center wing tanks. That supplemental NPRM also proposed to require 
replacing the left and right override/jettison switches on the M154 
fuel control module on the P4 panel with improved switches and doing 
the associated wiring changes. That supplemental NPRM also proposed to 
require, for certain airplanes, installation of a mounting bracket for 
the new indicator lights. That supplemental NPRM also proposed to 
require a revision to the maintenance program to incorporate 
airworthiness

[[Page 78592]]

limitation No. 28-AWL-22. That supplemental NPRM also proposed to 
require a revision to the airplane flight manual to advise the 
flightcrew what to do in the event that the pump low pressure light on 
the flight engineer's panel does not illuminate when the pump is 
selected off.

Comments

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

Clarification

    In our response in the supplemental NPRM to Northwest Airline's 
Request to Reference Later Revision of Service Bulletin Cited in 
Original NPRM, we described some of the changes in Boeing Service 
Bulletin 747-28A2288, Revision 1, dated January 21, 2010. That service 
bulletin was described as having installation instructions for the LOW 
PRESS indicator lights for airplanes that did not have the warning 
panel (i.e., the P10 panel) installed. We also described the changes to 
paragraph (g) of the Supplemental NPRM. We have revised the Summary and 
paragraph (g) of this AD to clarify that both groups of airplanes, with 
or without the warning panel installed, must install the two new 
indicator lights on certain panels (either the P10 panel, or for those 
airplanes without the P10 panel installed, the Autopilot Flight 
Director panel).

Conclusion

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

Costs of Compliance

    We estimate that this AD affects 185 airplanes of U.S. registry.
    We estimate the following costs to comply with 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

    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 this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.

    Note 1:  This AD requires revisions to certain operator 
maintenance documents to include a new inspection. Compliance with 
this inspection is required by 14 CFR 91.403(c). For airplanes that 
have been previously modified, altered, or repaired in the areas 
addressed by this inspection, the operator may not be able to 
accomplish the inspections 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 (AMOC) 
according to paragraph (l) of this AD. The request should include a 
description of changes to the required inspection that will ensure 
the continued operational safety of the airplane.

Subject

    (d) Air Transport Association (ATA) of America Code 28: Fuel.

Unsafe Condition

    (e) This AD results from fuel system reviews conducted by the 
manufacturer. The Federal Aviation Administration is issuing this AD 
to prevent uncommanded operation of the override/jettison pumps of 
the center wing tanks, and failure to manually shut off

[[Page 78593]]

the override/jettison pumps at the correct time, either of which 
could lead to an ignition source inside the center wing tank. This 
condition, in combination with flammable fuel vapors, could result 
in a center fuel tank explosion and consequent loss of the airplane.

Compliance

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

Installation of Indicator Lights and Replacement of Switches

    (g) Within 36 months after the effective date of this AD: For 
airplanes with a P10 panel installed, add two new indicator lights 
on the P10 panel to inform the captain and first officer of a low 
pressure condition in the left and right override/jettison pumps of 
the center wing tanks, and, for airplanes that do not have the 
warning panel (P10 panel) installed, add a mounting bracket and two 
new indicator lights to the Autopilot Flight Director panel; and 
replace the left and right override/jettison switches on the M154 
fuel control module on the P4 panel with improved switches; and do 
the associated wiring changes. Accomplish these actions by doing all 
of the applicable actions specified in the Accomplishment 
Instructions of Boeing Service Bulletin 747-28A2288, Revision 1, 
dated January 21, 2010, except where that service bulletin states 
``20-60-00,'' the correct sub-section number is ``28-60-06,'' and 
except as described in Table 1 of this AD.

into the AFM.

``When the center tank override jettison pumps are selected off, the 
amber pump low pressure lights on the Flight Engineer's panel should 
illuminate and remain on. If a pump low pressure light on the Flight 
Engineer's panel does not illuminate, open the associated pump 
circuit breaker.''

    Note 3:  When a statement identical to that in paragraph (i) of 
this AD has been included in the general revisions of the AFM, the 
general revisions may be inserted into the AFM, and the copy of this 
AD may be removed from the AFM.

No Alternative Inspections or Inspection Intervals

    (j) After accomplishing the action specified in paragraph (h) of 
this AD, no alternative inspections or inspection intervals may be 
used unless the inspections or inspection intervals are approved as 
an AMOC in accordance with the procedures specified in paragraph (l)
