Unsafe Condition
(d) This AD is the result of several reports
of fatigue cracking on the affected airplanes
in the auxiliary wing spar. We are issuing
this AD to detect and correct such cracks,
which, if not corrected, could result in failure
of the wing auxiliary spar web and cause
landing gear collapse during normal landing.
This could lead to loss of control and
passenger injury.
Compliance
(e) To address this problem, you must do
the actions below using Cessna Service
Bulletin MEB08–8, dated December 23, 2008,
at the following compliance time, unless
already done:
Note 1: Cessna Service Bulletin MEB08–8,
dated December 23, 2008, provides detailed
instructions on measuring, inspecting, and
replacing cracked parts, including how to
handle two or more cracks in the same hole.
(1) Within the next 10 hours time-inservice (TIS) after March 2, 2009 (the
effective date of this AD) and, in addition,
before further flight anytime the airplane
experiences a ‘‘hard landing,’’ visually
inspect the auxiliary wing spar near the
location where the main landing gear
trunnion is mounted for cracks.
(2) If any crack is found during any
inspection required by this AD that is 0.5
inch or more, before further flight after any
such crack is found, replace the cracked
parts.
(3) If cracks are found during any
inspection required by this AD that are less
than 0.5 inch, do the following:
(i) Repetitively thereafter inspect the cracks
for length at intervals not to exceed 50 hours
TIS and, before further flight, replace any
part that has a crack length of 0.5 inch or
more; and
(ii) Replace the cracked part within 200
hours TIS after the original crack was found
or within 12 months after the original crack
was found, whichever occurs first.
(4) If you find any cracks as a result of any
inspection required by this AD, report the
results to Cessna using the form in the
service bulletin. Send a copy of this report
VerDate Nov<24>2008
11:38 Feb 17, 2009
Jkt 217001
to the FAA at the address specified in
paragraph (f) of this AD. For the reporting
requirement in this AD, under the provisions
of the Paperwork Reduction Act, the Office
of Management and Budget (OMB) has
approved the information collection
requirements and has assigned OMB Control
Number 2120–0056. Do the reporting
requirement at whichever of the following
that occurs later:
(i) Within 10 days after the inspection; or
(ii) Within the next 10 days after March 2,
2009 (the effective date of this AD).
Note 2: The FAA considers this interim
action. We will work with Cessna and
evaluate the crack reports and all other
information. Based on this information, we
may initiate additional rulemaking action.

SUMMARY: We are adopting a new
airworthiness directive (AD) for certain
Learjet Model 55, 55B, and 55C
airplanes. This AD requires inspecting
the installation of the forward light

assembly in the aft lavatory to
determine the location of the terminal
connector; inspecting for damage of the
light assembly terminals, wires, and
oxygen lines; inspecting to determine if
the cable nipple is installed over the
light assembly terminal; and doing
corrective actions if necessary. This AD
also requires installing a clamp to the
forward side of the frame to maintain a
positive distance between the light
assembly and oxygen line. This AD
results from a report of a cabin fire in
the left-hand upper cabin fuselage above
the aft cabin window at frame 23. We
are issuing this AD to detect and correct
improper installation of the lavatory
light assembly, which could result in
contact between the electrical terminals
of the light assembly and an adjacent
oxygen supply line, and consequent
short circuit or fire hazard.
DATES: This AD is effective March 5,
2009.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of March 5, 2009.
We must receive comments on this
AD by April 20, 2009.

SUPPLEMENTARY INFORMATION:
Discussion
We received a report of a cabin fire in
the left-hand upper cabin fuselage above
the aft cabin window at frame 23 on a
Learjet Model 55 airplane. If installed
incorrectly, the power lead terminals of
the lavatory light assembly have the
potential to chafe against the oxygen
line, causing deterioration of the
insulation on the light assembly wiring.
This condition, if not corrected, could
result in contact between the electrical
terminals of the light assembly and an
adjacent oxygen supply line, and
consequent short circuit or fire hazard.
Relevant Service Information
We reviewed Bombardier Alert
Service Bulletin A55–25–7, dated
December 17, 2008. The alert service
bulletin describes procedures for an
inspection of the installation of the
forward light assembly in the aft
lavatory to determine the location of the
terminal connector (as shown in Figure
1, detail A of the alert service bulletin);
an inspection for damage of the light
assembly terminals, wires, and oxygen
line; an inspection to determine if the
cable nipple is installed over the light
assembly terminal; and corrective
actions if necessary. The corrective
actions include turning the light
assembly to locate the terminal
connector in the forward position;
replacing damaged light assembly
terminals, wires, and oxygen line; and
installing a new cable nipple. The alert
service bulletin also describes
procedures for installing a clamp to the
forward side of the frame to maintain a
positive distance between the light
assembly and oxygen line.
FAA’s Determination and Requirements
of This AD
We are issuing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the(se)
same type design(s). This AD requires
accomplishing the actions specified in
the service information described
previously, except as discussed under
‘‘Differences Between the AD and the
Service Information.’’

Differences Between the AD and the
Service Information
Operators should note that, although
the Accomplishment Instructions of the
Bombardier Alert Service Bulletin A55–
25–7, dated December 17, 2008,
describes procedures for submitting
information to the manufacturer, this
AD does not require that action.
Bombardier Alert Service Bulletin
A55–25–7, dated December 17, 2008,
refers only to doing ‘‘inspections.’’ We
have determined that the procedures in
the alert service bulletin should be
described as ‘‘general visual
inspections.’’ Note 1 has been included
in this AD to define this type of
inspection.
FAA’s Justification and Determination
of the Effective Date
This condition has the potential to
compromise the integrity of the oxygen
line due to the chafing between the light
assembly terminals and oxygen line and
has the potential to become an oxygenfueled ignition source. Because of our
requirement to promote safe flight of
civil aircraft and thus the critical need
to ensure the risk of fire is mitigated by
proper installation of the forward light
assembly in the aft lavatory and proper
positive distance maintained between
the oxygen line and light assembly, and
the short compliance time involved
with this action, this AD must be issued
immediately.
Because an unsafe condition exists
that requires the immediate adoption of
this AD, we find that notice and
opportunity for prior public comment
hereon are impracticable and that good
cause exists for making this amendment
effective in less than 30 days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety, and
we did not provide you with notice and
an opportunity to provide your
comments before it becomes effective.
However, we invite you to send any
written data, views, or arguments about
this AD. Send your comments to an
address listed under the ADDRESSES
section. Include ‘‘Docket No. FAA–
2009–0054; Directorate Identifier 2008–
NM–222–AD’’ at the beginning of your
comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of this AD. We will consider all
comments received by the closing date
and may amend this AD because of
those comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any

substantive verbal contact we receive
about this AD.
Authority for This Rulemaking
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), 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.

evaluation and the estimated costs of
compliance in the AD Docket.

SUPPLEMENTARY INFORMATION:
cprice-sewell on PRODPC61 with RULES
History
On December 8, 2008, the FAA
published in the Federal Register a
notice of proposed rulemaking to amend
Class E airspace at Atlantic, IA, adding
additional controlled airspace at
Atlantic Municipal Airport, Atlantic, IA.
(73 FR 74376, Docket No. FAA–2008–
1105). Interested parties were invited to
participate in this rulemaking effort by
submitting written comments on the
proposal to the FAA. No comments
were received. Class E airspace
designations are published in paragraph
VerDate Nov<24>2008
11:38 Feb 17, 2009
Jkt 217001
6005 of FAA Order 7400.9S signed
October 3, 2008, and effective October
31, 2008, which is incorporated by
reference in 14 CFR Part 71.1. The Class
E airspace designations listed in this
document will be published
subsequently in that Order.
The Rule
This action amends Title 14 Code of
Federal Regulations (14 CFR) Part 71 by
amending Class E airspace at Atlantic,
IA, adding additional controlled
airspace at Atlantic Municipal Airport,
Atlantic, IA.
The FAA has determined that this
regulation only involves an established
body of technical regulations for which
frequent and routine amendments are
necessary to keep them operationally
current. Therefore, this regulation: (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)
does not warrant preparation of a
regulatory evaluation as the anticipated
impact is so minimal. Since this is a
routine matter that will only affect air
traffic procedures and air navigation, it
is certified that this rule, when
promulgated, will not have a significant
economic impact on a substantial
number of small entities under the
criteria of the Regulatory Flexibility Act.
The FAA’s authority to issue rules
regarding aviation safety is found in
Title 49 of the U.S. Code. Subtitle 1,
Section 106, describes the authority of
the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more
detail the scope of the agency’s
authority. This rulemaking is
promulgated under the authority
described in Subtitle VII, Part A,
Subpart I, Section 40103. Under that
section, the FAA is charged with
prescribing regulations to assign the use
of airspace necessary to ensure the
safety of aircraft and the efficient use of
airspace. This regulation is within the
scope of that authority as it adds
additional controlled airspace at
Atlantic Municipal Airport, Atlantic, IA.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Learjet Model 55, 55B, and 55C airplanes. This AD requires inspecting
the installation of the forward light
[[Page 7555]]
assembly in the aft lavatory to determine the location of the terminal
connector; inspecting for damage of the light assembly terminals,
wires, and oxygen lines; inspecting to determine if the cable nipple is
installed over the light assembly terminal; and doing corrective
actions if necessary. This AD also requires installing a clamp to the
forward side of the frame to maintain a positive distance between the
light assembly and oxygen line. This AD results from a report of a
cabin fire in the left-hand upper cabin fuselage above the aft cabin
window at frame 23. We are issuing this AD to detect and correct
improper installation of the lavatory light assembly, which could
result in contact between the electrical terminals of the light
assembly and an adjacent oxygen supply line, and consequent short
circuit or fire hazard.
DATES: This AD is effective March 5, 2009.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 5,
2009.

SUPPLEMENTARY INFORMATION:
Discussion
We received a report of a cabin fire in the left-hand upper cabin
fuselage above the aft cabin window at frame 23 on a Learjet Model 55
airplane. If installed incorrectly, the power lead terminals of the
lavatory light assembly have the potential to chafe against the oxygen
line, causing deterioration of the insulation on the light assembly
wiring. This condition, if not corrected, could result in contact
between the electrical terminals of the light assembly and an adjacent
oxygen supply line, and consequent short circuit or fire hazard.
Relevant Service Information
We reviewed Bombardier Alert Service Bulletin A55-25-7, dated
December 17, 2008. The alert service bulletin describes procedures for
an inspection of the installation of the forward light assembly in the
aft lavatory to determine the location of the terminal connector (as
shown in Figure 1, detail A of the alert service bulletin); an
inspection for damage of the light assembly terminals, wires, and
oxygen line; an inspection to determine if the cable nipple is
installed over the light assembly terminal; and corrective actions if
necessary. The corrective actions include turning the light assembly to
locate the terminal connector in the forward position; replacing
damaged light assembly terminals, wires, and oxygen line; and
installing a new cable nipple. The alert service bulletin also
describes procedures for installing a clamp to the forward side of the
frame to maintain a positive distance between the light assembly and
oxygen line.
FAA's Determination and Requirements of This AD
We are issuing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the(se) same type
design(s). This AD requires accomplishing the actions specified in the
service information described previously, except as discussed under
``Differences Between the AD and the Service Information.''
Differences Between the AD and the Service Information
Operators should note that, although the Accomplishment
Instructions of the Bombardier Alert Service Bulletin A55-25-7, dated
December 17, 2008, describes procedures for submitting information to
the manufacturer, this AD does not require that action.
Bombardier Alert Service Bulletin A55-25-7, dated December 17,
2008, refers only to doing ``inspections.'' We have determined that the
procedures in the alert service bulletin should be described as
``general visual inspections.'' Note 1 has been included in this AD to
define this type of inspection.
FAA's Justification and Determination of the Effective Date
This condition has the potential to compromise the integrity of the
oxygen line due to the chafing between the light assembly terminals and
oxygen line and has the potential to become an oxygen-fueled ignition
source. Because of our requirement to promote safe flight of civil
aircraft and thus the critical need to ensure the risk of fire is
mitigated by proper installation of the forward light assembly in the
aft lavatory and proper positive distance maintained between the oxygen
line and light assembly, and the short compliance time involved with
this action, this AD must be issued immediately.
Because an unsafe condition exists that requires the immediate
adoption of this AD, we find that notice and opportunity for prior
public comment hereon are impracticable and that good cause exists for
making this amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments before it becomes effective. However, we invite
you to send any written data, views, or arguments about this AD. Send
your comments to an address listed under the ADDRESSES section. Include
``Docket No. FAA-2009-0054; Directorate Identifier 2008-NM-222-AD'' at
the beginning of your comments. We specifically invite comments on the
overall regulatory, economic, environmental, and energy aspects of this
AD. We will consider all comments received by the closing date and may
amend this AD because of those comments.
We will post all comments we receive, without change, to https://
www.regulations.gov, including any
[[Page 7556]]
personal information you provide. We will also post a report
summarizing each substantive verbal contact we receive about this AD.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.
