Federal Register / Vol. 75, No. 186 / Monday, September 27, 2010 / Rules and Regulations
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 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 summary of the costs
to comply with this AD and placed it in
the AD Docket. You may get a copy of
this summary at the address listed
under ADDRESSES.
List of Subjects in 14 CFR Part 39
Effective Date
(a) This airworthiness directive (AD)
becomes effective October 12, 2010.
Unsafe Condition
(d) This AD results from reports of engines

ACTION: Final rule.
AGENCY:
The FAA is superseding an
existing airworthiness directive (AD),
which applies to all Model 750
airplanes. That AD currently requires
inspecting the inboard-hinge brackets of
the left and right elevators for cracking
and doing related investigative and
corrective actions if necessary. For
certain airplanes, this new AD requires
inspecting for cracks of the bracket of
the inboard horizontal stabilizer and
measuring the lug thickness of the
horizontal stabilizer hinges; doing
corrective actions if necessary; and
modifying the left and right elevators
and left and right horizontal stabilizer.
For all airplanes, this new AD requires
replacing the existing elevator

assemblies with new elevator
assemblies, which terminates the
requirements of the existing AD. This
new AD also revises the applicability to
remove certain airplanes. This AD
results from a report of cracking found
on the elevator inboard-hinge brackets
and the horizontal stabilizer hinges. We
are issuing this AD to prevent such
cracking of the elevator inboard-hinge
brackets and the horizontal stabilizer
hinges, which could result in structural
failure of the elevators and consequent
loss of control of the airplane.
DATES: This AD becomes effective
November 1, 2010.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in the AD
as of November 1, 2010.
On November 22, 2006 (71 FR 65047,

Federal Register approved the
incorporation by reference of a certain
other publication listed in the AD.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
VerDate Mar<15>2010
16:28 Sep 24, 2010
Jkt 220001
part 39 to include an AD that
supersedes AD 2006–23–05, amendment
39–14817 (71 FR 65047, November 7,
2006). The existing AD applies to all
Model 750 airplanes. That NPRM was
published in the Federal Register on
April 8, 2010 (75 FR 17879). That NPRM
proposed to continue to require
inspecting the inboard-hinge brackets of
the left and right elevators for cracking
and doing related investigative and
corrective actions if necessary. For
certain airplanes that NPRM proposed
to require an inspection for cracks and
corrosion of the bracket of the inboard
horizontal stabilizer and measuring the
lug thickness of the horizontal stabilizer
hinges; doing corrective actions if
necessary; and modifying the left and
right elevators and left and right
horizontal stabilizer. For all airplanes,
that NPRM proposed to require
replacing the existing elevator
assemblies with new elevator
assemblies, which would terminate the
requirements of the existing AD. That
NPRM also proposed to revise the
applicability to remove certain
airplanes.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments that have
been received on the NPRM.
Request To Remove References to
Corrosion
Cessna Aircraft Company requests
that in the ‘‘Differences Between the
Proposed AD and Service Bulletin’’
section of the NPRM the sentence, ‘‘This
proposed AD would also require an
inspection for corrosion and
replacement of any corroded brackets,’’
be removed. Cessna states that corrosion
of the brackets has not been an issue,
and current maintenance practices are
sufficient. Cessna states that the
requirement to inspect the horizontal
hinge brackets for corrosion will
complicate compliance for operators
that have already complied with
previous revisions of Cessna Service
Bulletin SB750–27–62. Cessna states
that the addition of an inspection for
corrosion of the horizontal inboard
hinge in paragraph (k)(1) of the NPRM
is not specified in Cessna Service
Bulletin SB750–27–62, Revision 3,
dated August 21, 2009.
We agree with Cessna’s request. Since
the NPRM was issued, we have received
sufficient technical information to
PO 00000
Frm 00007
Fmt 4700
Sfmt 4700
59063
support the request. We have changed
the AD to remove references to
corrosion.
Request To Clarify Table 1 of the NPRM
Cessna states that it is unclear which
requirements of paragraph (k) of the
NPRM are covered by previous revisions
of Cessna Service Bulletin SB750–27–
62. Cessna requests that we amend
Table 1 of the NPRM to reference
paragraphs (k)(1), (k)(2), and (k)(3) of the
NPRM.
We partially agree with Cessna’s
request. In lieu of revising Table 1 of
this AD, we have changed paragraph (l)
of this AD to show that actions
accomplished before the effective date
of this AD, in accordance with the
service bulletins identified in Table 1 of
this AD, are considered acceptable for
compliance with the corresponding
requirements of paragraphs ‘‘(k)(1),
(k)(2), and (k)(3) of this AD.’’
Request To Clarify the Effect of
Previous Compliance
JATEC requests that we explain how
the NPRM affects airplanes that have
already complied with Cessna Service
Bulletin SB750–27–62, Revision 3,
dated August 21, 2009. JATEC asks if
anything further is required once
Revision 3 has been incorporated.
As specified in paragraph (f) of this
AD, you are responsible for having the
actions required by this AD performed
within the compliance time specified,
unless the actions have already been
done. In addition, as specified in
paragraph (k) of this AD, once the
actions required by that paragraph are
accomplished, the requirements of
paragraphs (g) through (j) of this AD are
terminated; no further action is
required. No changes to this AD are
necessary in this regard.
Conclusion
We have carefully reviewed the
available data, including the comments
that have been received, and determined
that air safety and the public interest
require adopting the AD with the
changes described previously. We have
determined that these changes will
neither increase the economic burden
on any operator nor increase the scope
of the AD.

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.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to all Model 750 airplanes. That AD currently
requires inspecting the inboard-hinge brackets of the left and right
elevators for cracking and doing related investigative and corrective
actions if necessary. For certain airplanes, this new AD requires
inspecting for cracks of the bracket of the inboard horizontal
stabilizer and measuring the lug thickness of the horizontal stabilizer
hinges; doing corrective actions if necessary; and modifying the left
and right elevators and left and right horizontal stabilizer. For all
airplanes, this new AD requires replacing the existing elevator
[[Page 59063]]
assemblies with new elevator assemblies, which terminates the
requirements of the existing AD. This new AD also revises the
applicability to remove certain airplanes. This AD results from a
report of cracking found on the elevator inboard-hinge brackets and the
horizontal stabilizer hinges. We are issuing this AD to prevent such
cracking of the elevator inboard-hinge brackets and the horizontal
stabilizer hinges, which could result in structural failure of the
elevators and consequent loss of control of the airplane.
DATES: This AD becomes effective November 1, 2010.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of November 1,
2010.
On November 22, 2006 (71 FR 65047, November 7, 2006), the Director
of the Federal Register approved the incorporation by reference of a
certain other publication listed in the AD.

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 2006-23-05, amendment
39-14817 (71 FR 65047, November 7, 2006). The existing AD applies to
all Model 750 airplanes. That NPRM was published in the Federal
Register on April 8, 2010 (75 FR 17879). That NPRM proposed to continue
to require inspecting the inboard-hinge brackets of the left and right
elevators for cracking and doing related investigative and corrective
actions if necessary. For certain airplanes that NPRM proposed to
require an inspection for cracks and corrosion of the bracket of the
inboard horizontal stabilizer and measuring the lug thickness of the
horizontal stabilizer hinges; doing corrective actions if necessary;
and modifying the left and right elevators and left and right
horizontal stabilizer. For all airplanes, that NPRM proposed to require
replacing the existing elevator assemblies with new elevator
assemblies, which would terminate the requirements of the existing AD.
That NPRM also proposed to revise the applicability to remove certain
airplanes.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments that have been
received on the NPRM.
Request To Remove References to Corrosion
Cessna Aircraft Company requests that in the ``Differences Between
the Proposed AD and Service Bulletin'' section of the NPRM the
sentence, ``This proposed AD would also require an inspection for
corrosion and replacement of any corroded brackets,'' be removed.
Cessna states that corrosion of the brackets has not been an issue, and
current maintenance practices are sufficient. Cessna states that the
requirement to inspect the horizontal hinge brackets for corrosion will
complicate compliance for operators that have already complied with
previous revisions of Cessna Service Bulletin SB750-27-62. Cessna
states that the addition of an inspection for corrosion of the
horizontal inboard hinge in paragraph (k)(1) of the NPRM is not
specified in Cessna Service Bulletin SB750-27-62, Revision 3, dated
August 21, 2009.
We agree with Cessna's request. Since the NPRM was issued, we have
received sufficient technical information to support the request. We
have changed the AD to remove references to corrosion.
Request To Clarify Table 1 of the NPRM
Cessna states that it is unclear which requirements of paragraph
(k) of the NPRM are covered by previous revisions of Cessna Service
Bulletin SB750-27-62. Cessna requests that we amend Table 1 of the NPRM
to reference paragraphs (k)(1), (k)(2), and (k)(3) of the NPRM.
We partially agree with Cessna's request. In lieu of revising Table
1 of this AD, we have changed paragraph (l) of this AD to show that
actions accomplished before the effective date of this AD, in
accordance with the service bulletins identified in Table 1 of this AD,
are considered acceptable for compliance with the corresponding
requirements of paragraphs ``(k)(1), (k)(2), and (k)(3) of this AD.''
Request To Clarify the Effect of Previous Compliance
JATEC requests that we explain how the NPRM affects airplanes that
have already complied with Cessna Service Bulletin SB750-27-62,
Revision 3, dated August 21, 2009. JATEC asks if anything further is
required once Revision 3 has been incorporated.
As specified in paragraph (f) of this AD, you are responsible for
having the actions required by this AD performed within the compliance
time specified, unless the actions have already been done. In addition,
as specified in paragraph (k) of this AD, once the actions required by
that paragraph are accomplished, the requirements of paragraphs (g)
through (j) of this AD are terminated; no further action is required.
No changes to this AD are necessary in this regard.
Conclusion
We have carefully reviewed the available data, including the
comments that have been received, and determined that air safety and
the public interest require adopting the AD with the changes described
previously. We have determined that these changes will neither increase
the economic burden on any operator nor increase the scope of the AD.
Costs of Compliance
The following table provides the estimated costs 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
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.

Service Bulletin SB750-27-62, Revision 3, dated August 21, 2009.
Subject
(d) Air Transport Association (ATA) of America Code 27: Flight
Controls.
Unsafe Condition
(e) This AD results from a report of cracking found on the
elevator inboard-hinge brackets and the horizontal stabilizer
hinges. The Federal Aviation Administration is issuing this AD to
prevent cracking of the elevator inboard-hinge brackets and the
horizontal stabilizer hinges, which could result in structural
failure of the elevators and consequent loss of control of the
airplane.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Restatement of Requirements of AD 2006-23-05, With No Changes
Inspection
(g) After the airplane accumulates 2,500 total flight hours:
Perform a general visual inspection for cracking of the inboard-
hinge brackets of the left and right elevators in accordance with
the Accomplishment Instructions of Cessna Alert Service Letter
ASL750-27-21, dated October 13, 2006. Do the inspection before the
airplane accumulates 3,000 total flight hours, or within 10 flight
hours after November 22, 2006 (the effective date of AD 2006-23-05),
whichever is later.
Note 1: For the purposes of this AD, a general visual
inspection is: ``A visual examination of an 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 enhance visual access to all exposed surfaces in the
inspection area. This level of inspection is made under normally
available lighting conditions such as daylight, hangar lighting,
flashlight, or droplight 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.''
Related Investigative and Corrective Actions
(h) If any crack is found during the inspection required by
paragraph (g) of this AD: Before further flight, perform an eddy
current inspection of the inboard-hinge brackets to determine the
crack length, in accordance with the Accomplishment Instructions of
Cessna Alert Service Letter ASL750-27-21, dated October 13, 2006;
and do the actions specified in paragraph (h)(1) or (h)(2) of this
AD, as applicable, at the time specified. All corrective actions
must be done using a method approved by the Manager, Wichita
Aircraft Certification Office (ACO), FAA. For a replacement method
to be approved by the Manager, Wichita ACO, as required by this
paragraph, the Manager's approval letter must specifically refer to
this AD.
[[Page 59065]]
(1) If the crack is 0.30 inch or more: Replace the bracket
before further flight.
(2) If the crack is less than 0.30 inch: Continued flight for a
maximum of 10 flight hours for repositioning of the airplane and
replacement of the bracket is allowed, within the restricted flight
envelope included in the attachment to Cessna Alert Service Letter
ASL750-27-21, dated October 13, 2006, titled ``Flight
Restrictions.''
Special Flight Permits
(i) Special flight permits, as described in Section 39.23 of the
Federal Aviation Regulations (14 CFR 39.23), are allowed with the
limitations required by paragraph (h)(2) of this AD.
No Reporting or Return of Parts to Manufacturer
(j) Cessna Alert Service Letter ASL750-27-21, dated October 13,
2006, specifies submitting a sheet related to inspection results to
the manufacturer; this AD does not include that requirement. The
service letter also specifies sending the elevator assembly to the
manufacturer for replacement of the inboard-hinge bracket if a crack
is found that is 0.30 inch or more; however, this AD requires
corrective actions be done using a method approved by us.
New Requirements of This AD
(k) Within 60 months after the effective date of this AD, do the
applicable actions required by paragraphs (k)(1), (k)(2), (k)(3),
and (k)(4) of this AD, in accordance with the Accomplishment
Instructions of Cessna Service Bulletin SB750-27-62, Revision 3,
dated August 21, 2009. Accomplishing the actions required by
paragraph (k) of this AD terminates the requirements of paragraphs
(g) through (j) of this AD.
(1) For all airplanes except those having S/Ns 288 through 305
inclusive: Do an eddy current inspection for cracks of the bracket
of the inboard horizontal stabilizer. Before further flight, replace
any cracked bracket of the inboard horizontal stabilizer with a
serviceable bracket.
(2) For all airplanes except those having S/Ns 288 through 305
inclusive: Measure the lug thickness of the horizontal stabilizer
hinges. If the lug thickness is not within the acceptable tolerance
range, as identified in Cessna Service Bulletin SB750-27-62,
Revision 3, dated August 21, 2009, before further flight, replace
the bearing plate with a serviceable bearing plate.
(3) For all airplanes except those having S/Ns 288 through 305
inclusive: Modify the left and right horizontal stabilizer; and add
the modification part number of the horizontal stabilizer to the
modification section of the MS27253-1 identification plate.
(4) For all airplanes: Replace the existing elevator assemblies
with new elevator assemblies having part numbers 6734000-17 (for the
left side) and 6734000-18 (for the right side).
Credit for Actions Done Using the Previous Service Information
(l) Actions accomplished before the effective date of this AD in
accordance with the service bulletins identified in Table 1 of this
AD are considered acceptable for compliance with the corresponding
