This AD results from an IFE systems review. We are issuing this AD to ensure that the flightcrew is able to turn off electrical power to IFE systems and other nonessential electrical systems through a switch in the flight compartment. The flightcrew’s inability to turn off power to IFE systems and other non-essential electrical systems during a non-normal or emergency situation could result in the inability to control smoke or fumes in the airplane flight deck or cabin. DATES: This AD is effective July 16, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of July 16, 2009.

SUPPLEMENTARY INFORMATION: Discussion 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 737–300, –400, –500, –600, –700, –700C, –800, and –900 series airplanes. That NPRM was published in the Federal Register on November 7, 2007 (72 FR 62802). That NPRM proposed to require installing a new circuit breaker, relays, and wiring to allow the flightcrew to turn off E:\FR\FM\11JNR1.SGM 11JNR1 Federal Register / Vol. 74, No. 111 / Thursday, June 11, 2009 / Rules and Regulations electrical power to the in-flight entertainment (IFE) systems and other non-essential electrical systems through a switch in the flight compartment, and doing other specified actions. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received from the six commenters. cprice-sewell on PRODPC61 with RULES Request To Exclude Certain Airplanes From the Applicability Mr. Ian S. Murton requests that we revise paragraph (c)(2) of the applicability of the NPRM to exclude Model 737–700 series airplanes having variable numbers (V/Ns) YB101 through YB114 inclusive. These airplanes are listed in the effectivity of Boeing Service Bulletin 737–24–1147, Revision 1, dated March 1, 2007, which is referenced in paragraph (c)(2) of the NPRM. As justification, the commenter states that the operator of these airplanes has owned the airplanes since delivery from Boeing, and that IFE systems are not installed on these airplanes. The commenter also states that the operator took possession of the airplane having V/N YB114 18 months after Boeing issued the original issue of Boeing Service Bulletin 737–24–1147, dated November 20, 2003, and that the operator decided not to accomplish the actions specified in that service bulletin. The commenter would like to know how the proposed requirements of the NPRM would affect this range of airplanes. The commenter also states that perhaps the applicability of the NPRM should be amended to include only airplanes that have the IFE systems installed. We disagree with revising the applicability of this AD because we have determined that the unsafe condition exists on the airplanes identified in the Boeing service bulletins that are referenced in paragraph (c) of this AD. The effectivities of those service bulletins are based upon the delivered configuration of the airplanes. Boeing has confirmed that it installed IFE systems on airplanes having V/Ns YB101 through YB114 inclusive. If the IFE systems were either removed after delivery, or have never been installed contrary to the effectivity of Boeing Service Bulletin 737–24–1147, Revision 1, dated March 1, 2007, then under the provisions of paragraph (k) of this AD, we will consider requests for approval of an alternative method of compliance (AMOC) if sufficient data are submitted to substantiate that the design change is VerDate Nov<24>2008 14:23 Jun 10, 2009 Jkt 217001 not necessary. We have not changed the AD in this regard. Request To Exclude Certain Boeing Business Jets From the Applicability Boeing Executive Flight Operations requests that we revise paragraph (c) of the applicability of the NPRM to exclude certain Boeing business jets (BBJs) equipped with a passenger entertainment switch (PES), certified under a Supplemental Type Certificate (STC). If these airplanes are not excluded from the applicability, then the commenter requests that the FAA provide additional detail on what specific interior systems or equipment need to have a means of disconnection, so that operators can accurately petition and apply for an AMOC. The commenter states that Boeing delivered these airplanes without an interior to a customized completion center, where they were modified to a custom interior specification and design that are certified by an STC. According to the commenter, many of the BBJ interior installations incorporate either a PES, or load shed switching, that will remove power from the interior equipment and systems, as required by sections 25.1309, 25.1351, 25.1353, and 25.1355 of the Federal Aviation Regulations (14 CFR 25.1309, 14 CFR 25.1351, 14 CFR 25.1353, and 14 CFR 25.1355). The commenter also states that Boeing Service Bulletin 737–24– 1147, Revision 1, dated March 1, 2007, does not consider the BBJ and BBJ2 configurations separate from commercial airline interior configurations and does not provide enough details as to what systems or equipment need to be isolated with the PES disconnects. We disagree with revising the applicability of this AD because we have determined that the unsafe condition exists on the airplanes identified in the Boeing service bulletins that are referenced in paragraph (c) of this AD. The effectivities of those service bulletins are based upon the delivered configuration of the airplanes. The ‘‘load shed switching’’ function is for an overload condition during normal operation where power will be removed from non-essential systems, such as galley, IFE systems, etc. This AD, however, has a different purpose, which is to independently remove power from the IFE systems and other non-essential equipment in case of emergency, according to FAA Policy Memorandum PS–ANM100–2000–00105, ‘‘Interim Policy Guidance for Certification of InFlight Entertainment Systems on Title 14 CFR Part 25 Aircraft,’’ dated PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 27699 September 18, 2000. Policy Memorandum PS–ANM100–2000– 00105 specifies that there should be a manual main shutoff switch within reach of flight or cabin crews to be used in case of emergency to shut off all nonessential power. FAA Policy Memorandum ANM–01–111–165, ‘‘Policy Statement on Certification of Power Supply Systems for Portable Electronic Devices (PES) on Part 25 Airplanes,’’ dated March 18, 2005, covers the PES power removal switch as well. Under the provisions of paragraph (k) of this AD, we will consider requests for approval of an AMOC if sufficient data are submitted to substantiate that an alternate design change would provide an acceptable level of safety. We have not changed the AD in this regard. Requests To Allow Certain Service Bulletins as AMOCs Aircraft Maintenance Engineering Services SARL requests that we consider the following service information as AMOCs to the proposed requirements of the NPRM: • Lufthansa Technik Engineering Bulletin 737–EB24–0073, Revision 01, for addressing the unsafe condition on the Model 737–700 series airplane having serial number (S/N) 29972. • Lufthansa Technik Engineering Bulletin 737–EB24–0088, Revision 01, for addressing the unsafe condition on the Model 737–800 series airplane having S/N 32438. • Raytheon Service Bulletin 737IGW– 24–1, dated August 11, 2000, for addressing the unsafe condition on the Model 737–700 series airplane having S/N 28976. The commenter states that these bulletins address the intent of Boeing Service Bulletin 737–24–1147, Revision 1, dated March 1, 2007. The Lufthansa Technik engineering bulletins provide procedures for installing a cut-off switch in the P5 panel to interrupt electrical power to the IFE system. The Raytheon service bulletin provides procedures for installing a flight compartment switch for removing power from the IFE systems and other non-essential systems. The procedures in the Raytheon service bulletin were accomplished in accordance with STC ST09106AC–D, issued July 6, 2000. We disagree because an AMOC can be granted only after an AD has been issued. In addition, we have not included the Lufthansa and Raytheon service bulletins as a method of compliance within this AD; we do not consider it appropriate to include various provisions in an AD applicable only to individual airplane serial E:\FR\FM\11JNR1.SGM 11JNR1 27700 Federal Register / Vol. 74, No. 111 / Thursday, June 11, 2009 / Rules and Regulations numbers or to a single operator’s unique use of an affected airplane. Once we issue this AD, the commenter may request approval of an AMOC under the provisions of paragraph (k) of this AD. Sufficient data must be submitted to substantiate that the design change would provide an acceptable level of safety. We have not changed the AD in this regard. Request To Revise Paragraph (f) of the NPRM Boeing requests that we delete the last sentence of paragraph (f) of the NPRM, which states: ‘‘Concurrently Modify P5– 13 Module Assembly on Model 737–300 Series Airplanes.’’ Boeing states that the sentence is redundant and confusing because the concurrent requirements are addressed by paragraph (h) of the NPRM, and that those requirements only apply to a certain group of airplanes. We disagree because the phrase that the commenter refers to is not a sentence in paragraph (f) of the NPRM. That phrase is the heading for paragraph (g) of the NPRM, which gives the concurrent requirements. No change to the AD is necessary in this regard. Request To Extend the Compliance Time The Air Transport Association, on behalf of its member American Airlines, requests that we extend the compliance time from 60 to 72 months. American Airlines states that it is requesting this extension to align the compliance time with its heavy maintenance program and to avoid an unnecessary financial burden. American Airlines states that incorporating the modification requires extensive ‘‘power off A/C time,’’ and that this can be accommodated only at a heavy C check, which is scheduled by most in the industry at 72-month intervals. American Airlines also states that the proposed 60-month compliance time will have a substantial impact by requiring the unscheduled removal of its airplanes from service. American Airlines estimates that 14 of its affected airplanes will require special scheduling and out-of-service time, which equates to about 42 days for an additional cost impact of $600,000. We disagree with extending the compliance time. In developing an appropriate compliance time for this action, we considered the safety implications, parts availability, and normal maintenance schedules for the timely accomplishment of the modification. In consideration of these items, we have determined that a 60month compliance time will ensure an acceptable level of safety. However, according to the provisions of paragraph (k) of this AD, we might approve requests to adjust the compliance time if the request includes data that prove that the new compliance time would provide an acceptable level of safety. We have not changed the AD in this regard. Change Made to Paragraph (i) of This AD We have revised paragraph (i) of this AD to specify that the requirements of that paragraph apply to ‘‘* * * Groups 3 through 139. * * *’’ In the NPRM, we inadvertently specified that the proposed requirements would apply to Groups 1 through 139. This change agrees with paragraph 1.B. of Boeing Service Bulletin 737–24–1147, Revision 1, dated March 1, 2007. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the change described previously. We also determined that this change will not increase the economic burden on any operator or increase the scope of the AD. Costs of Compliance There are about 1,617 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs, at an average labor rate of $80 per hour, for U.S. operators to comply with this AD.

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. VerDate Nov<24>2008 14:23 Jun 10, 2009 Jkt 217001 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 PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 Fleet cost 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 E:\FR\FM\11JNR1.SGM 11JNR1 27701 Federal Register / Vol. 74, No. 111 / Thursday, June 11, 2009 / Rules and Regulations 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.

The MCAI states: Incidents have been reported on BrittenNorman BN–2 aircraft, where cracks were found in the inner shell of the pitot/static pressure heads. The investigation concluded that these pitot tubes, supplied by Thales Optronics, could be operated outside their voltage specification.

This condition, if not corrected, could result in incorrect readings on the pressure instrumentation, e.g., altimeters, vertical speed indicators (rate of climb) and airspeed indicators, potentially leading to navigational errors. For the reasons described above, this EASA AD requires the inspection of the affected pitot tubes, and, if cracks are found, replacement of those tubes with the new P/ N [part number] 212–A0150–0001 and 212– A0150–0002 pitot tubes. The unsafe condition could reduce the ability of the flightcrew to maintain the safe flight and landing of the airplane. You may obtain further information by examining the MCAI in the AD docket.

Airworthiness Directives; Boeing Model 737-300, -400, -500, -600,
-700, -700C, -800, and -900 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Boeing Model 737-300, -400, -500, -600, -700, -700C, -800, and -900
series airplanes. This AD requires installing a new circuit breaker,
relays, and wiring to allow the flightcrew to turn off electrical power
to the in-flight entertainment (IFE) systems and other non-essential
electrical systems through a switch in the flight compartment, and
doing other specified actions. This AD results from an IFE systems
review. We are issuing this AD to ensure that the flightcrew is able to
turn off electrical power to IFE systems and other non-essential
electrical systems through a switch in the flight compartment. The
flightcrew's inability to turn off power to IFE systems and other non-
essential electrical systems during a non-normal or emergency situation
could result in the inability to control smoke or fumes in the airplane
flight deck or cabin.

DATES: This AD is effective July 16, 2009.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of July 16,
2009.

SUPPLEMENTARY INFORMATION:

Discussion

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 737-300, -400, -500, -600, -700, -700C, -800, and
-900 series airplanes. That NPRM was published in the Federal Register
on November 7, 2007 (72 FR 62802). That NPRM proposed to require
installing a new circuit breaker, relays, and wiring to allow the
flightcrew to turn off

[[Page 27699]]

electrical power to the in-flight entertainment (IFE) systems and other
non-essential electrical systems through a switch in the flight
compartment, and doing other specified actions.

Comments

We gave the public the opportunity to participate in developing
this AD. We considered the comments received from the six commenters.

Request To Exclude Certain Airplanes From the Applicability

Mr. Ian S. Murton requests that we revise paragraph (c)(2) of the
applicability of the NPRM to exclude Model 737-700 series airplanes
having variable numbers (V/Ns) YB101 through YB114 inclusive. These
airplanes are listed in the effectivity of Boeing Service Bulletin 737-
24-1147, Revision 1, dated March 1, 2007, which is referenced in
paragraph (c)(2) of the NPRM. As justification, the commenter states
that the operator of these airplanes has owned the airplanes since
delivery from Boeing, and that IFE systems are not installed on these
airplanes. The commenter also states that the operator took possession
of the airplane having V/N YB114 18 months after Boeing issued the
original issue of Boeing Service Bulletin 737-24-1147, dated November
20, 2003, and that the operator decided not to accomplish the actions
specified in that service bulletin. The commenter would like to know
how the proposed requirements of the NPRM would affect this range of
airplanes. The commenter also states that perhaps the applicability of
the NPRM should be amended to include only airplanes that have the IFE
systems installed.
We disagree with revising the applicability of this AD because we
have determined that the unsafe condition exists on the airplanes
identified in the Boeing service bulletins that are referenced in
paragraph (c) of this AD. The effectivities of those service bulletins
are based upon the delivered configuration of the airplanes. Boeing has
confirmed that it installed IFE systems on airplanes having V/Ns YB101
through YB114 inclusive. If the IFE systems were either removed after
delivery, or have never been installed contrary to the effectivity of
Boeing Service Bulletin 737-24-1147, Revision 1, dated March 1, 2007,
then under the provisions of paragraph (k) of this AD, we will consider
requests for approval of an alternative method of compliance (AMOC) if
sufficient data are submitted to substantiate that the design change is
not necessary. We have not changed the AD in this regard.

Request To Exclude Certain Boeing Business Jets From the Applicability

Boeing Executive Flight Operations requests that we revise
paragraph (c) of the applicability of the NPRM to exclude certain
Boeing business jets (BBJs) equipped with a passenger entertainment
switch (PES), certified under a Supplemental Type Certificate (STC). If
these airplanes are not excluded from the applicability, then the
commenter requests that the FAA provide additional detail on what
specific interior systems or equipment need to have a means of
disconnection, so that operators can accurately petition and apply for
an AMOC. The commenter states that Boeing delivered these airplanes
without an interior to a customized completion center, where they were
modified to a custom interior specification and design that are
certified by an STC.
According to the commenter, many of the BBJ interior installations
incorporate either a PES, or load shed switching, that will remove
power from the interior equipment and systems, as required by sections
25.1309, 25.1351, 25.1353, and 25.1355 of the Federal Aviation
Regulations (14 CFR 25.1309, 14 CFR 25.1351, 14 CFR 25.1353, and 14 CFR
25.1355). The commenter also states that Boeing Service Bulletin 737-
24-1147, Revision 1, dated March 1, 2007, does not consider the BBJ and
BBJ2 configurations separate from commercial airline interior
configurations and does not provide enough details as to what systems
or equipment need to be isolated with the PES disconnects.
We disagree with revising the applicability of this AD because we
have determined that the unsafe condition exists on the airplanes
identified in the Boeing service bulletins that are referenced in
paragraph (c) of this AD. The effectivities of those service bulletins
are based upon the delivered configuration of the airplanes.
The ``load shed switching'' function is for an overload condition
during normal operation where power will be removed from non-essential
systems, such as galley, IFE systems, etc. This AD, however, has a
different purpose, which is to independently remove power from the IFE
systems and other non-essential equipment in case of emergency,
according to FAA Policy Memorandum PS-ANM100-2000-00105, ``Interim
Policy Guidance for Certification of In-Flight Entertainment Systems on
Title 14 CFR Part 25 Aircraft,'' dated September 18, 2000. Policy
Memorandum PS-ANM100-2000-00105 specifies that there should be a manual
main shutoff switch within reach of flight or cabin crews to be used in
case of emergency to shut off all non-essential power. FAA Policy
Memorandum ANM-01-111-165, ``Policy Statement on Certification of Power
Supply Systems for Portable Electronic Devices (PES) on Part 25
Airplanes,'' dated March 18, 2005, covers the PES power removal switch
as well.
Under the provisions of paragraph (k) of this AD, we will consider
requests for approval of an AMOC if sufficient data are submitted to
substantiate that an alternate design change would provide an
acceptable level of safety. We have not changed the AD in this regard.

Requests To Allow Certain Service Bulletins as AMOCs

Aircraft Maintenance Engineering Services SARL requests that we
consider the following service information as AMOCs to the proposed
requirements of the NPRM:
Lufthansa Technik Engineering Bulletin 737-EB24-0073,
Revision 01, for addressing the unsafe condition on the Model 737-700
series airplane having serial number (S/N) 29972.
Lufthansa Technik Engineering Bulletin 737-EB24-0088,
Revision 01, for addressing the unsafe condition on the Model 737-800
series airplane having S/N 32438.
Raytheon Service Bulletin 737IGW-24-1, dated August 11,
2000, for addressing the unsafe condition on the Model 737-700 series
airplane having S/N 28976.
The commenter states that these bulletins address the intent of
Boeing Service Bulletin 737-24-1147, Revision 1, dated March 1, 2007.
The Lufthansa Technik engineering bulletins provide procedures for
installing a cut-off switch in the P5 panel to interrupt electrical
power to the IFE system. The Raytheon service bulletin provides
procedures for installing a flight compartment switch for removing
power from the IFE systems and other non-essential systems. The
procedures in the Raytheon service bulletin were accomplished in
accordance with STC ST09106AC-D, issued July 6, 2000.
We disagree because an AMOC can be granted only after an AD has
been issued. In addition, we have not included the Lufthansa and
Raytheon service bulletins as a method of compliance within this AD; we
do not consider it appropriate to include various provisions in an AD
applicable only to individual airplane serial

[[Page 27700]]

numbers or to a single operator's unique use of an affected airplane.
Once we issue this AD, the commenter may request approval of an AMOC
under the provisions of paragraph (k) of this AD. Sufficient data must
be submitted to substantiate that the design change would provide an
acceptable level of safety. We have not changed the AD in this regard.

Request To Revise Paragraph (f) of the NPRM

Boeing requests that we delete the last sentence of paragraph (f)
of the NPRM, which states: ``Concurrently Modify P5-13 Module Assembly
on Model 737-300 Series Airplanes.'' Boeing states that the sentence is
redundant and confusing because the concurrent requirements are
addressed by paragraph (h) of the NPRM, and that those requirements
only apply to a certain group of airplanes.
We disagree because the phrase that the commenter refers to is not
a sentence in paragraph (f) of the NPRM. That phrase is the heading for
paragraph (g) of the NPRM, which gives the concurrent requirements. No
change to the AD is necessary in this regard.

Request To Extend the Compliance Time

The Air Transport Association, on behalf of its member American
Airlines, requests that we extend the compliance time from 60 to 72
months. American Airlines states that it is requesting this extension
to align the compliance time with its heavy maintenance program and to
avoid an unnecessary financial burden. American Airlines states that
incorporating the modification requires extensive ``power off A/C
time,'' and that this can be accommodated only at a heavy C check,
which is scheduled by most in the industry at 72-month intervals.
American Airlines also states that the proposed 60-month compliance
time will have a substantial impact by requiring the unscheduled
removal of its airplanes from service. American Airlines estimates that
14 of its affected airplanes will require special scheduling and out-
of-service time, which equates to about 42 days for an additional cost
impact of $600,000.
We disagree with extending the compliance time. In developing an
appropriate compliance time for this action, we considered the safety
implications, parts availability, and normal maintenance schedules for
the timely accomplishment of the modification. In consideration of
these items, we have determined that a 60-month compliance time will
ensure an acceptable level of safety. However, according to the
provisions of paragraph (k) of this AD, we might approve requests to
adjust the compliance time if the request includes data that prove that
the new compliance time would provide an acceptable level of safety. We
have not changed the AD in this regard.

Change Made to Paragraph (i) of This AD

We have revised paragraph (i) of this AD to specify that the
requirements of that paragraph apply to ``* * * Groups 3 through 139. *
* *'' In the NPRM, we inadvertently specified that the proposed
requirements would apply to Groups 1 through 139. This change agrees
with paragraph 1.B. of Boeing Service Bulletin 737-24-1147, Revision 1,
dated March 1, 2007.

Conclusion

We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD with the change described previously. We also determined that
this change will not increase the economic burden on any operator or
increase the scope of the AD.

Costs of Compliance

There are about 1,617 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs, at
an average labor rate of $80 per hour, for U.S. operators 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

[[Page 27701]]

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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.
