ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Boeing airplanes listed above. This AD requires an inspection of certain lighted pushbutton switches in the flight compartment for configuration ‘D’ master modules and part numbers and corrective action if necessary. This AD also provides an option to inspect panel assemblies for part numbers. This AD results from a report indicating that the integrated drive generator failed in flight due to a possible switch malfunction. We are issuing this AD to ensure that certain lighted pushbutton switches in the flight compartment do not malfunction and cause the flightcrew to be unable to control critical airplane systems and continue safe airplane operation. This AD becomes effective February 28, 2008. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of February 28, 2008.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Boeing Model 747–400, –400D, and –400F series airplanes; Boeing Model 757 airplanes; and Boeing Model 767 airplanes. That NPRM was published in the Federal Register on August 16, 2007 (72 FR 45986). That NPRM proposed to require an inspection of certain lighted pushbutton switches in the flight compartment for configuration ‘D’ master modules and part numbers and corrective action if necessary. That NPRM also provided an option to inspect panel assemblies for part numbers. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Support for the NPRM Boeing, the airplane manufacturer, concurs with the content of the NPRM. Request To Remove Reference to Revision 1 of the Service Bulletins Japan Airlines requests that we remove the reference in the NPRM to Boeing Alert Service Bulletins 747– 33A2280 and 767–33A0087, both Revision 1, both dated September 25, 2003 (we referred to those service bulletins as appropriate sources of service information for doing the actions specified in the NPRM). The commenter notes that it has incorporated Boeing Alert Service Bulletins 747–33A2280 and 767–33A0087, both dated December 19, 2001, for its Model 747–400 and Model 767–200/–300 fleets. The commenter notes that it strictly controls the configuration ‘D’ master module. However, the commenter states it did not carry out some top assembly module part number changes according to the PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 instructions of Revision 1 of the service bulletins because in some cases the original top assembly module part number was not indicated anywhere, or was indicated unclearly. The commenter believes that it is impossible to follow the part number change indicated in Revision 1 of the service bulletins and notes that because it tracks the base module, it can ignore the top assembly module part number. The commenter also states that Boeing agrees that Japan Airlines does not need to perform Revision 1 of the service bulletins because the changes to the bulletin caused by Revision 1 do not affect Japan Airlines’ fleet/units. We disagree with removing the reference to Boeing Alert Service Bulletins 747–33A2280 and 767– 33A0087, both Revision 1. We acknowledge that each operator may wish to use different parts and have its own tracking methods. However, we cannot accommodate every operator’s differences in each AD. We have determined that the best way to handle such circumstances is for operators to request an alternative method of compliance (AMOC) in accordance with paragraph (p) of this AD, rather than increasing the complexity of the AD by addressing each operator’s unique situation. We have not revised this AD in this regard. Conclusion We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance There are about 2,511 airplanes of the affected designs in the worldwide fleet. This AD affects about 934 airplanes of U.S. registry. The inspection of switches takes about 8 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the inspection for U.S. operators is $597,760, or $640 per airplane. 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 E:\FR\FM\24JAR1.SGM 24JAR1 Federal Register / Vol. 73, No. 16 / Thursday, January 24, 2008 / Rules and Regulations 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 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); 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. See the ADDRESSES section for a location to examine the regulatory evaluation. 4067 PART 39—AIRWORTHINESS DIRECTIVES 1.

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Boeing airplanes listed above. This AD requires an inspection 
of certain lighted pushbutton switches in the flight compartment for 
configuration `D' master modules and part numbers and corrective action 
if necessary. This AD also provides an option to inspect panel 
assemblies for part numbers. This AD results from a report indicating 
that the integrated drive generator failed in flight due to a possible 
switch malfunction. We are issuing this AD to ensure that certain 
lighted pushbutton switches in the flight compartment do not 
malfunction and cause the flightcrew to be unable to control critical

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Boeing Model 
747-400, -400D, and -400F series airplanes; Boeing Model 757 airplanes; 
and Boeing Model 767 airplanes. That NPRM was published in the Federal 
Register on August 16, 2007 (72 FR 45986). That NPRM proposed to 
require an inspection of certain lighted pushbutton switches in the 
flight compartment for configuration `D' master modules and part 
numbers and corrective action if necessary. That NPRM also provided an 
option to inspect panel assemblies for part numbers.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Support for the NPRM

    Boeing, the airplane manufacturer, concurs with the content of the 
NPRM.

Request To Remove Reference to Revision 1 of the Service Bulletins

    Japan Airlines requests that we remove the reference in the NPRM to 
Boeing Alert Service Bulletins 747-33A2280 and 767-33A0087, both 
Revision 1, both dated September 25, 2003 (we referred to those service 
bulletins as appropriate sources of service information for doing the 
actions specified in the NPRM). The commenter notes that it has 
incorporated Boeing Alert Service Bulletins 747-33A2280 and 767-
33A0087, both dated December 19, 2001, for its Model 747-400 and Model 
767-200/-300 fleets. The commenter notes that it strictly controls the 
configuration `D' master module. However, the commenter states it did 
not carry out some top assembly module part number changes according to 
the instructions of Revision 1 of the service bulletins because in some 
cases the original top assembly module part number was not indicated 
anywhere, or was indicated unclearly.
    The commenter believes that it is impossible to follow the part 
number change indicated in Revision 1 of the service bulletins and 
notes that because it tracks the base module, it can ignore the top 
assembly module part number.
    The commenter also states that Boeing agrees that Japan Airlines 
does not need to perform Revision 1 of the service bulletins because 
the changes to the bulletin caused by Revision 1 do not affect Japan 
Airlines' fleet/units.
    We disagree with removing the reference to Boeing Alert Service 
Bulletins 747-33A2280 and 767-33A0087, both Revision 1. We acknowledge 
that each operator may wish to use different parts and have its own 
tracking methods. However, we cannot accommodate every operator's 
differences in each AD. We have determined that the best way to handle 
such circumstances is for operators to request an alternative method of 
compliance (AMOC) in accordance with paragraph (p) of this AD, rather 
than increasing the complexity of the AD by addressing each operator's 
unique situation. We have not revised this AD in this regard.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, and determined that air safety and the public 
interest require adopting the AD as proposed.

Costs of Compliance

    There are about 2,511 airplanes of the affected designs in the 
worldwide fleet. This AD affects about 934 airplanes of U.S. registry.
    The inspection of switches takes about 8 work hours per airplane, 
at an average labor rate of $80 per work hour. Based on these figures, 
the estimated cost of the inspection for U.S. operators is $597,760, or 
$640 per airplane.

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

[[Page 4067]]

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 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); 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

Inspection

    (h) Within 60 months after the effective date of this AD: Do a 
general visual inspection of the switches specified in paragraphs 
(h)(1), (h)(2), (h)(3), (h)(4), and (h)(5) of this AD, as 
applicable, to identify configuration `D' master modules and the 
part number (P/N) of the switch, in accordance with the applicable 
service bulletin, except as provided by paragraph (i) of this AD.

    Note 2: For the purposes of this AD, a general visual inspection 
is ``A visual examination of a interior or exterior area, 
installation or assembly to detect obvious damage, failure or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normal available lighting 
conditions such as daylight, hangar lighting, flashlight or drop-
light and may require removal or opening of access panels or doors. 
Stands, ladders or platforms may be required to gain proximity to 
the area being checked.''

    (1) For Model 757-200, -200CB, and -200PF series airplanes: 
Switches identified in step 1 and step 3 of Figure 1 of Boeing Alert 
Service Bulletin 757-33A0044, Revision 1, dated September 25, 2003.
    (2) For Model 757-300 series airplanes: Switches identified in 
step 1 of Figure 1 of Boeing Alert Service Bulletin 757-33A0045, 
Revision 1, dated September 25, 2003.
    (3) For Model 767-200, -300, and -300F series airplanes: 
Switches identified in step 1 of Figure 1 of Boeing Alert Service 
Bulletin 767-33A0087, Revision 1, dated September 25, 2003.
    (4) For Model 767-400ER series airplanes: Switches identified in 
step 1 of Figure 1 of Boeing Alert Service Bulletin 767-33A0088, 
dated December 19, 2001.
    (5) For all airplanes: Switches identified for the panel 
assemblies specified in the applicable service bulletin.

Optional Inspection

    (i) Instead of doing the inspection required by paragraph (h) of 
this AD, operators may inspect the part number of the panel 
assemblies specified in paragraphs (i)(1) and (i)(2) of this AD, as 
applicable, at the time specified in paragraph (h) of this AD. If 
the part number is identified as a new part number in paragraph 2.E. 
``Existing Parts Accountability'' or Appendix B of the applicable 
service bulletin, no further action is required. If the part number 
is not identified as a new part number, the inspection required by 
paragraph (h) of this AD must be done at the specified time.
    (1) For switches identified in paragraphs (h)(1), (h)(2), 
(h)(3), and (h)(4) of this AD: P3-1 and P10 panel assemblies, as 
applicable.
    (2) For switches identified in paragraph (h)(5) of this AD: The 
panel assemblies identified in the applicable service bulletin.

Corrective Action

    (j) If during any inspection required by paragraph (h) of this 
AD, any switch is found that does not have a configuration `D' 
switch master module and no switch part number specified in 
paragraph (j)(1)(i) or (j)(1)(ii) of this AD is found: Before 
further flight, do the actions specified in either paragraph (j)(1) 
or (j)(2) of this AD and do the part number revision, as applicable, 
specified in paragraph (j)(3) of this AD.

[[Page 4069]]

    (1) Replace the switch with a switch specified in paragraph 
(j)(1)(i), (j)(1)(ii), or (j)(1)(iii) of this AD, in accordance with 
the applicable service bulletin, except as provided by paragraph (k) 
of this AD.
    (i) Switches having Boeing P/N S231T290-4201 through -4325 
inclusive.
    (ii) Switches having Korry P/N 4336731004-4201 through -4325 
inclusive.

    Note 3: One-to-one switch correlation between the existing 
switches and the new part number switches can be found in Korry 
Service Bulletin 433-33-06, dated November 7, 2001.

    (iii) Switches that have a configuration `D' master module.
    (2) Replace the switch master module with a new configuration 
`D' master module in accordance with the applicable service 
bulletin.
    (3) If all switches on a panel assembly have a configuration `D' 
master module or have a switch part number specified in paragraph 
(j)(1)(i) or (j)(1)(ii) of this AD: Revise the part number of the 
panel assembly in accordance with the applicable service bulletin.
    (k) If during any inspection required by paragraph (h) of this 
AD, a configuration `D' switch master module is found or the switch 
part number is specified in paragraph (j)(1)(i) or (j)(1)(ii) of 
this AD on all switches for a panel assembly: Before further flight, 
revise the part number of the panel assembly, in accordance with the 
applicable service bulletin.

Contact the FAA/Removal and Installation Procedures

    (l) If the applicable service bulletin specifies removal or 
installation of certain parts and does not specify removal or 
installation instructions: Before further flight, remove or install 
those parts according to a method approved by the Manager, Seattle 
Aircraft Certification Office (ACO), FAA, or by doing the actions 
specified in paragraph (l)(1) of this AD for removal or paragraph 
(l)(2) of this AD for installation, as applicable.
    (1) Remove the module/panel assembly by doing the actions 
specified in paragraphs (l)(1)(i), (l)(1)(ii), and (l)(1)(iii) of 
this AD.
    (i) Hold the module/panel assembly in position and loosen the 
quick-release screws.
    (ii) Carefully lower the module/panel assembly from the overhead 
panel.
    (iii) Remove the electrical connectors attached to the rear of 
the module/panel assembly.
    (2) Install the module/panel assembly by doing the actions 
specified in paragraphs (l)(2)(i) and (l)(2)(ii) of this AD.
    (i) Make sure that the module/panel assembly is correctly

    (n) Where paragraph 3.B.14.b.(3) of the Accomplishment 
Instructions of Boeing Alert Service Bulletin 747-33A2280, Revision 
1, dated September 25, 2003, specifies procedures to do a test of 
the engine ignition control/fuel jettison module assembly, this AD 
requires that operators dry-motor the engine to remove the fuel from 
the tailpipe before doing the procedures in paragraph 3.B.14.b.(3). 
All fuel must be removed from the engine tailpipe before performing 
the test, because during the test the engine igniter will be 
energized.
