Discussion
We received reports of cracks found
in the exhaust mufflers of Liberty
Aerospace Incorporated (Liberty
Aerospace) Model XL–2 airplanes. One
crack was found during maintenance,
which prompted Liberty Aerospace to
publish service information requesting
the exhaust mufflers be inspected for
cracks on all Model XL–2 airplanes.
Seven additional cracks have been
found during these service inspections.
Investigation is ongoing to determine
what is causing the exhaust mufflers to
VerDate Nov<24>2008
16:45 Apr 08, 2009
Jkt 217001
crack. Excessive vibration caused by
improper propeller clocking position
may be a contributing factor.
This condition, if not corrected, could
result in carbon monoxide entering the
cabin through the heating system and
cause incapacitation of the pilot.
Relevant Service Information
We reviewed Liberty Aerospace, Inc.
Service Document Critical Service
Bulletin (CSB) CSB–09–001, Revision
Level B, Revised on March 18, 2009.
The service information describes
procedures for inspecting the exhaust
muffler for cracks and replacing the
exhaust muffler when cracks are found.
FAA’s Determination and Requirements
of This AD
We are issuing this AD because we
evaluated all the information and
determined the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design. This AD requires
repetitively inspecting the exhaust
muffler for cracks and replacing the
exhaust muffler when cracks are found.
This AD also requires inspecting the
propeller for proper clocking position
and correcting any discrepancies found.
Liberty Aerospace is reviewing the
information related to the occurrences
referenced in this AD and may develop
a modification that, when incorporated,
would eliminate the need for the
repetitive inspections required by this
AD. The FAA will review any
modification that is developed,
determine whether it would eliminate
the need for the requirements of this
action, and then determine whether
additional AD action is necessary.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD. The FAA has found that the risk to
the flying public justifies waiving notice
and comment prior to adoption of this
rule because cracks in the exhaust
muffler could result in carbon monoxide
entering the cabin through the heating
system. Carbon monoxide entering into
the airplane cabin could lead to
incapacitation of the pilot. Therefore,
we determined that notice and
opportunity for public comment before
issuing this AD are impracticable and
that good cause exists for making this
amendment effective in fewer than 30
days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety, and
we did not precede it by notice and an
PO 00000
Frm 00022
Fmt 4700
Sfmt 4700
opportunity for public comment. We
invite you to send any written relevant
data, views, or arguments regarding this
AD. Send your comments to an address
listed under the ADDRESSES section.
Include the docket number ‘‘FAA–
2009–0329; Directorate Identifier 2009–
CE–020–AD’’ at the beginning of your
comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of the AD. We will consider all
comments received by the closing date
and may amend the AD in light of those
comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
concerning 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
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 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

procedures for retaining optimum
position determination and intended
navigation. This new AD requires
upgrading new software, which
terminates the existing requirements.
This AD results from reports of in-flight
unannunciated shifts of computed
position in airplanes with the subject
FMS computers. We are issuing this AD
to prevent a shift in the FMS computed
position, which could result in
uncommanded deviations from the
intended flight path of the airplane, and,
if those deviations are undetected by the
flight crew, compromised terrain/traffic
avoidance.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that
supersedes AD 2007–07–12, amendment
39–15009 (72 FR 15818, April 3, 2007).
The existing AD applies to all
Honeywell FMSs served by Honeywell
NZ–2000 navigation computers and IC–
800 integrated avionics computers. That
NPRM was published in the Federal
Register on August 21, 2008 (73 FR
49368). That NPRM proposed to retain
the existing requirements of identifying
affected airplanes by part numbers/
modification levels and revising the
Limitations section of the airplane flight
manual. That NPRM also proposed to
require uploading new software, which
would terminate the existing
requirements.
Actions Since NPRM Was Issued
Since we issued the NPRM,
Honeywell has published Alert Service
Bulletin 7017300–22–A6112, Revision
001, dated February 7, 2008. In the
NPRM, we referred to Honeywell Alert
Service Bulletin 7017300–22–A6112,
dated June 22, 2007, as the appropriate
source of service information for
accomplishing the proposed actions.
The procedures in Revision 001 of this
service bulletin are essentially the same
as those in the original issue of this
service bulletin. Revision 001 of this
service bulletin includes instructions to

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Liberty Aerospace Incorporated Model XL-2 airplanes. This AD requires
you to repetitively inspect the exhaust muffler for cracks and to
replace the exhaust muffler when cracks are found. This AD is the
result of reports that cracks have been found in the exhaust muffler
during maintenance and service inspections. We are issuing this AD to
detect and correct cracks in the exhaust muffler, which could result in
carbon monoxide entering the cabin through the heating system. Carbon
monoxide entering into the airplane cabin could lead to incapacitation
of the pilot.

SUPPLEMENTARY INFORMATION:
Discussion
We received reports of cracks found in the exhaust mufflers of
Liberty Aerospace Incorporated (Liberty Aerospace) Model XL-2
airplanes. One crack was found during maintenance, which prompted
Liberty Aerospace to publish service information requesting the exhaust
mufflers be inspected for cracks on all Model XL-2 airplanes. Seven
additional cracks have been found during these service inspections.
Investigation is ongoing to determine what is causing the exhaust
mufflers to crack. Excessive vibration caused by improper propeller
clocking position may be a contributing factor.
This condition, if not corrected, could result in carbon monoxide
entering the cabin through the heating system and cause incapacitation
of the pilot.
Relevant Service Information
We reviewed Liberty Aerospace, Inc. Service Document Critical
Service Bulletin (CSB) CSB-09-001, Revision Level B, Revised on March
18, 2009. The service information describes procedures for inspecting
the exhaust muffler for cracks and replacing the exhaust muffler when
cracks are found.
FAA's Determination and Requirements of This AD
We are issuing this AD because we evaluated all the information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This AD requires
repetitively inspecting the exhaust muffler for cracks and replacing
the exhaust muffler when cracks are found. This AD also requires
inspecting the propeller for proper clocking position and correcting
any discrepancies found.
Liberty Aerospace is reviewing the information related to the
occurrences referenced in this AD and may develop a modification that,
when incorporated, would eliminate the need for the repetitive
inspections required by this AD. The FAA will review any modification
that is developed, determine whether it would eliminate the need for
the requirements of this action, and then determine whether additional
AD action is necessary.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because
cracks in the exhaust muffler could result in carbon monoxide entering
the cabin through the heating system. Carbon monoxide entering into the
airplane cabin could lead to incapacitation of the pilot. Therefore, we
determined that notice and opportunity for public comment before
issuing this AD are impracticable and that good cause exists for making
this amendment effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and an opportunity for
public comment. We invite you to send any written relevant data, views,
or arguments regarding this AD. Send your comments to an address listed
under the ADDRESSES section. Include the docket number ``FAA-2009-0329;
Directorate Identifier 2009-CE-020-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the AD. We will consider
all comments received by the closing date and may amend the AD in light
of those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive concerning 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
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 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
[[Page 16119]]
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 that contains the AD, the regulatory
evaluation, any comments received, and other information on the
Internet at https://www.regulations.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5527)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.
