Discussion
Reports of foreign material lodged in
a linear bearing (part number
LA57272500), which supports a pushpull tube in the aileron control system,
on a Model LC41–550FG airplane
caused us to issue AD 2007–07–06,
Amendment 39–15011 (72 FR 15822,
April 3, 2007). AD 2007–07–06
currently requires the following on
certain Cessna Models LC40–550FG,
LC41–550FG, and LC42–550FG
airplanes:
• Adding information to the
limitations section of the airplane flight
manual (AFM);
• Repetitively inspecting the aileron
and the elevator linear bearings and
control rods for foreign object debris,
scarring, or damage; and
• Taking all necessary corrective
actions.
Since issuing AD 2007–07–06, Cessna
has issued a new service bulletin that
contains procedures for installing a
linear bearing access panel to facilitate
doing the inspections required in AD
2007–07–06. The inspections required
in AD 2007–07–06 are to be done by
drilling a 3/4-inch diameter hole in the
flap cove.
45903
Cessna has also changed the serial
number applicability of the airplanes
affected by AD 2007–07–06. Production
methods have changed to eliminate the
possibility of bearing contamination
from adhesive during the assembly
process. The bearing design has been
changed to reduce the possibility of
jamming, and access panels in the lower
wing are now being installed during
production.
The airplane maintenance manual has
also been changed to incorporate an
annual inspection requirement of the
aileron linear bearings into the
maintenance program for new
production airplanes.
This condition, if not corrected, could
result in jamming of the aileron and
elevator control systems, which could
result in loss of control.
Relevant Service Information
We have reviewed Cessna Mandatory
Service Bulletins SB–07–002D and SB–
07–018, both dated May 29, 2008.
These service bulletins describe
procedures for:
• Adding information to the ‘‘Before
Starting Engine’’ checklist;
• Inspecting the aileron and the
elevator linear bearings and control rods
for foreign object debris, scarring, or
damage; and
• Installing a linear bearing access
panel.
FAA’s Determination and Requirements
of the Proposed AD
We are proposing this AD because we
evaluated all information and
determined the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design. This proposed AD would
revise AD 2007–07–06 with a new AD
that would retain the actions currently
required in AD 2007–07–06; allow
installing access panels; and change the
serial number applicability. This
proposed AD would require you to use
the service information described
previously to perform these actions.
Costs of Compliance
We estimate that this AD affects 1,495
airplanes in the U.S. registry.
We estimate the following costs to do
the proposed inspection:

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 have determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 the proposed regulation:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
2. Is not a ‘‘significant rule’’ under the
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 proposed AD and placed it in the
AD docket.
Examining the AD Docket
You may examine the AD docket that
contains the proposed 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) 647–5227) is located at the street
address stated in the ADDRESSES section.
Comments will be available in the AD
docket shortly after receipt.

SFAR 73 for two 5-year periods. The
FAA recently re-issued SFAR No. 73
and extended the rule’s expiration date
to June 30, 2009. SFAR No. 73 requires
special training and experience for
pilots operating the Robinson model R–
22 or R–44 helicopters in order to
maintain the safe operation of Robinson
helicopters. It also requires special
training and experience for certified
flight instructors conducting student
instruction or flight reviews in R–22 or

Discussion
Reports of foreign material lodged in a linear bearing (part number
LA57272500), which supports a push-pull tube in the aileron control
system, on a Model LC41-550FG airplane caused us to issue AD 2007-07-
06, Amendment 39-15011 (72 FR 15822, April 3, 2007). AD 2007-07-06
currently requires the following on certain Cessna Models LC40-550FG,
LC41-550FG, and LC42-550FG airplanes:
Adding information to the limitations section of the
airplane flight manual (AFM);
Repetitively inspecting the aileron and the elevator
linear bearings and control rods for foreign object debris, scarring,
or damage; and
Taking all necessary corrective actions.
Since issuing AD 2007-07-06, Cessna has issued a new service
bulletin that contains procedures for installing a linear bearing
access panel to facilitate doing the inspections required in AD 2007-
07-06. The inspections required in AD 2007-07-06 are to be done by
drilling a 3/4-inch diameter hole in the flap cove.
Cessna has also changed the serial number applicability of the
airplanes affected by AD 2007-07-06. Production methods have changed to
eliminate the possibility of bearing contamination from adhesive during
the assembly process. The bearing design has been changed to reduce the
possibility of jamming, and access panels in the lower wing are now
being installed during production.
The airplane maintenance manual has also been changed to
incorporate an annual inspection requirement of the aileron linear
bearings into the maintenance program for new production airplanes.
This condition, if not corrected, could result in jamming of the
aileron and elevator control systems, which could result in loss of
control.
Relevant Service Information
We have reviewed Cessna Mandatory Service Bulletins SB-07-002D and
SB-07-018, both dated May 29, 2008.
These service bulletins describe procedures for:
Adding information to the ``Before Starting Engine''
checklist;
Inspecting the aileron and the elevator linear bearings
and control rods for foreign object debris, scarring, or damage; and
Installing a linear bearing access panel.
FAA's Determination and Requirements of the Proposed AD
We are proposing this AD because we evaluated all information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This proposed AD
would revise AD 2007-07-06 with a new AD that would retain the actions
currently required in AD 2007-07-06; allow installing access panels;
and change the serial number applicability. This proposed AD would
require you to use the service information described previously to
perform these actions.
Costs of Compliance
We estimate that this AD affects 1,495 airplanes in the U.S.
registry.
We estimate the following costs to do the proposed inspection:
----------------------------------------------------------------------------------------------------------------
Total cost
Labor cost Parts cost Total cost on U.S.
per airplane operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $80 per hour = $320.............. Not applicable.................... $320 $478,400
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do the optional access panel
installation:
[[Page 45904]]
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per
airplane
------------------------------------------------------------------------
14 work-hours x $80 per hour = Not applicable........ $1,120
$1,120.
------------------------------------------------------------------------
Warranty credit for installing the access panel will be given to
the extent noted in Cessna Mandatory Service Bulletins SB-07-018, dated
May 29, 2008.
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 have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the proposed 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) 647-5227)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.
