SUPPLEMENTARY INFORMATION:
Discussion
We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD requires
an inspection of the elevator spar for
cracks and, if any crack is found, either
replacement with a serviceable elevator
spar that is found free of cracks or
repair/modification with an FAAapproved method. This AD also requires
reporting to the FAA the results of the
inspection. This AD was prompted by
reports of a total of nine elevator spar
cracks across seven of the affected
airplanes, including a crack of 2.35
inches just below the outboard hinge of
the right-hand elevator. We are issuing
this AD to prevent structural failure of
the elevator spar due to such cracking,
which could result in separation of the
elevator from the airplane with
consequent loss of control.
DATES: This AD is effective April 4,
2011.
We must receive comments on this
AD by May 19, 2011.
ADDRESSES: You may send comments by
any of the following methods:
• Federal eRulemaking Portal: Go to
https://www.regulations.gov. Follow the
instructions for submitting comments.
• Fax: 202–493–2251.

SUMMARY:
You may examine the AD docket 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 AD
docket contains this AD, the regulatory
evaluation, any comments received, and
other information. The street address for
the Docket Office (phone: 800–647–
5527) is in the ADDRESSES section.
Comments will be available in the AD
docket shortly after receipt.
The FAA has received a report from
CPAC, Inc. describing a crack of 2.35
inches just below the outboard hinge of
the right-hand elevator on a CPAC, Inc.
Model 114 airplane. The Models 112,
112B, 112TC, 112TCA, 114, 114A, 114B,
and 114TC have the same design of the
elevator spar and are all part of Type
Certificate A12SO. There have been a
total of nine elevator spar cracks across
seven of these airplanes.
Type Certificate A12SO does not
include Models 112A and 115. The
Model 112A is a Rockwell ‘‘marketing
name’’ for the Model 112. The Model
115 is a Rockwell ‘‘marketing name’’ for
the Model 114.
If not corrected, structural failure of
the elevator spar could result in
separation of the elevator from the
airplane with consequent loss of
control.
Relevant Service Information
We have included in this AD
procedures for removing the elevator
and inspecting the forward and aft sides
of the right-hand and left-hand elevator
forward spar web near and around the
outboard hinge area.
FAA’s Determination
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 same
type design.

AD Requirements
This AD requires an inspection of the
elevator spar for cracks and, if any crack
is found, replacement of the elevator
spar with a serviceable spar that is
found free of cracks or repair/
modification with an FAA-approved
method. This AD also requires reporting
to the FAA of the results of the
inspection.
Interim Action
We consider this AD interim action.
We are requiring a one-time inspection
of the elevator spar with a report to the
FAA of the results. We will work with
the type certificate holder to evaluate
that information to determine repetitive
inspection intervals and subsequent
terminating action. Based on this
evaluation, we may initiate further
rulemaking action to address the unsafe
condition identified in this AD.
FAA’s Justification and 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 structural failure of the
elevator spar would result in potential
separation of the elevator with
consequent loss of control.
Therefore, we find that notice and
opportunity for prior public comment
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
was not preceded by notice and an
opportunity for public comment.
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 the docket number
FAA–2011–0302 and Directorate
Identifier 2011–CE–008–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
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
about this AD.

Costs of Compliance
We estimate that this AD affects 773
airplanes of U.S. registry.
We estimate the following costs to
comply with this AD:
ESTIMATED COSTS

Currently, there is no FAA-approved
repair/modification for a cracked
elevator spar. Further flight is
prohibited until an FAA-approved
repair/modification is submitted to the
FAA and FAA-approved. A cracked
elevator spar could be replaced with a
serviceable one if one is available. The
FAA does not have availability and cost
information on serviceable elevator
spars. Therefore, at this time, the FAA
has no way of determining any oncondition costs associated with cracks
found in the elevator spar.
sroberts on DSK69SOYB1PROD with RULES
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),
VerDate Mar<15>2010
18:24 Apr 01, 2011

(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.

SUPPLEMENTARY INFORMATION:
SUMMARY:
History
On January 20, 2011, the FAA
published in the Federal Register a
notice of proposed rulemaking to amend
controlled airspace at Taylor, AZ (76 FR
3570). Interested parties were invited to
participate in this rulemaking effort by
submitting written comments on the
proposal to the FAA. No comments
were received. Subsequent to
publication, the FAA found the
geographic coordinates for Taylor
Airport needed to be adjusted to
coincide with the FAA’s aeronautical
database. This action makes the
adjustment. Also, the airport names
PO 00000
Frm 00032
Fmt 4700
Sfmt 4700
have been changed: Taylor Municipal
Airport to Taylor Airport, and Show
Low Municipal Airport to Show Low
Regional Airport. With the exception of
editorial changes, and the changes
described above, this rule is the same as
that proposed in the NPRM.
Class E airspace designations are
published in paragraph 6005 of FAA
Order 7400.9U dated August 18, 2010,
and effective September 15, 2010, 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
modifying Class E airspace extending
upward from 700 feet above the surface
at Taylor Airport, Taylor, AZ, to
accommodate IFR aircraft using the
CAMBO One Departure, and the RNAV
standard instrument approach
procedures at the airport. This action is
necessary for the safety and
management of IFR operations. The
geographic coordinates for Taylor
Airport will be adjusted to coincide
with the FAA’s aeronautical database.
Also, Taylor Municipal Airport has been
renamed Taylor Airport and Show Low
Municipal Airport has been renamed
Show Low Regional Airport.
The FAA has determined 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 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
discusses 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

SUPPLEMENTARY INFORMATION:
Discussion
The FAA has received a report from CPAC, Inc. describing a crack of
2.35 inches just below the outboard hinge of the right-hand elevator on
a CPAC, Inc. Model 114 airplane. The Models 112, 112B, 112TC, 112TCA,
114, 114A, 114B, and 114TC have the same design of the elevator spar
and are all part of Type Certificate A12SO. There have been a total of
nine elevator spar cracks across seven of these airplanes.
Type Certificate A12SO does not include Models 112A and 115. The
Model 112A is a Rockwell ``marketing name'' for the Model 112. The
Model 115 is a Rockwell ``marketing name'' for the Model 114.
If not corrected, structural failure of the elevator spar could
result in separation of the elevator from the airplane with consequent
loss of control.
Relevant Service Information
We have included in this AD procedures for removing the elevator
and inspecting the forward and aft sides of the right-hand and left-
hand elevator forward spar web near and around the outboard hinge area.
FAA's Determination
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 same type design.
AD Requirements
This AD requires an inspection of the elevator spar for cracks and,
if any crack is found, replacement of the elevator spar with a
serviceable spar that is found free of cracks or repair/modification
with an FAA-approved method. This AD also requires reporting to the FAA
of the results of the inspection.
Interim Action
We consider this AD interim action. We are requiring a one-time
inspection of the elevator spar with a report to the FAA of the
results. We will work with the type certificate holder to evaluate that
information to determine repetitive inspection intervals and subsequent
terminating action. Based on this evaluation, we may initiate further

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
structural failure of the elevator spar would result in potential
separation of the elevator with consequent loss of control.
Therefore, we find that notice and opportunity for prior public

Costs of Compliance
We estimate that this AD affects 773 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection of the elevator spar..... 8 work-hours x $85 per N/A $680 $525,640
hour = $680.
----------------------------------------------------------------------------------------------------------------
Currently, there is no FAA-approved repair/modification for a
cracked elevator spar. Further flight is prohibited until an FAA-
approved repair/modification is submitted to the FAA and FAA-approved.
A cracked elevator spar could be replaced with a serviceable one if one
is available. The FAA does not have availability and cost information
on serviceable elevator spars. Therefore, at this time, the FAA has no
way of determining any on-condition costs associated with cracks found
in the elevator spar.
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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2011-07-13 CPAC, Inc. (Type Certificate Formerly Held by Commander
Aircraft Corporation, Gulfstream Aerospace Corporation, and Rockwell
International): Amendment 39-16650; Docket No. FAA-2011-0302;
Directorate Identifier 2011-CE-008-AD.
Effective Date
(a) This AD is effective April 4, 2011.
Affected ADs
(b) None.
Applicability
(c) This AD applies to CPAC, Inc. (type certificate formerly
held by Commander Aircraft Corporation, Gulfstream Aerospace
Corporation, and Rockwell International) Models 112, 112B, 112TC,
112TCA, 114, 114A, 114B, and 114TC airplanes, all serial numbers,
certificated in any category. Type Certificate No. A12SO does not
include Models 112A and 115. The Model 112A is a Rockwell
``marketing name'' for the Model 112. The Model 115 is a Rockwell
``marketing name'' for the Model 114. Since they are type-
certificated as Model 112 and Model 114, this AD is applicable to
the Models 112A and 115.
Subject
(d) Joint Aircraft System Component (JASC)/Air Transport
Association (ATA) of America Code 55, Stabilizers.
Unsafe Condition
(e) This AD was prompted by reports of a total of nine elevator
spar cracks across seven of the affected airplanes, including a
crack of 2.35 inches just below the outboard hinge of the right-hand
elevator. We are issuing this AD to prevent structural failure of
the elevator spar due to such cracking, which could result in
separation of the elevator from the airplane with consequent loss of
control.
Compliance
(f) Comply with this AD within the compliance times specified.
Inspection/Repair
(g) Within the next 5 hours time-in-service after the effective
date of this AD, do the following for the left-hand and right-hand
elevators:
(1) Disconnect the elevator trim pushrod at the trim tab.
(2) Remove the hinge bolts at the horizontal stabilizer points.
(3) Remove six screws and two bolts at the inboard end of the
elevator and remove the elevator.
(4) Remove all fasteners common to the elevator outboard aft end
rib, part number (P/N) 44330, and elevator skin, P/N 44323.
(5) Remove the remaining two fasteners common to the elevator
outboard aft End rib (P/N 44330) and the elevator spar, P/N 44211.
(6) Remove the elevator aft end rib, P/N 44330, to gain access
to the aft side of the elevator spar.
(7) Remove the four bolts, washers, and nuts that secure the
outboard elevator hinge, P/N 44285.
(8) Remove elevator hinge, P/N 44285, from the elevator spar.
(9) Clean in and around the location of the outboard bracket on
the elevator spar and visually inspect for cracks. Use a 10X
magnifier to facilitate the detection of any crack.
(10) If cracks are found, before further flight, do the
following:
(i) Either replace the elevator spar with a serviceable spar
that is found free of cracks or repair/modify the elevator spar
following a procedure approved for this AD by the FAA, Wichita
Aircraft Certification Office (ACO); and
(ii) Reassemble the elevator assembly, rebalance the elevator,
and reinstall on the
[[Page 18378]]
airplane following standard repair practices. Ensure elevator
rigging is within tolerance, and that the system operates with ease,
smoothness, and positiveness appropriate to its function.
Note: Elevator rigging and rebalancing, torque values, and other
general maintenance information can be found in the maintenance
manual.
