ACTION: Final Rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
issued by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
SUMMARY:
mstockstill on DSK4VPTVN1PROD with RULES
It has been found that moisture may
accumulate and freeze, under certain
conditions, in the gap between the AOA vane
base assembly and the stationary ring of the
sensor’s body. If freezing occurs both AOA
sensors may get stuck and the Stall Warning
Protection System (SWPS) will be no longer
effective without alerting. This may result in
inadvertent aerodynamic stall and loss of
controllability of the airplane.
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
September 26, 2011.
On September 26, 2011, the Director
of the Federal Register approved the
incorporation by reference of certain
publications listed in this AD.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on May 10, 2011 (76 FR 26959).
That NPRM proposed to correct an
unsafe condition for the specified
products. The MCAI states:
It has been found that moisture may
accumulate and freeze, under certain
conditions, in the gap between the AOA vane
base assembly and the stationary ring of the
sensor’s body. If freezing occurs both AOA
sensors may get stuck and the Stall Warning
Protection System (SWPS) will be no longer
effective without alerting. This may result in
inadvertent aerodynamic stall and loss of
controllability of the airplane.
Since this condition may occur in other
airplanes of the same type and affects flight
safety, a corrective action is required. Thus,
sufficient reason exists to request compliance
with this AD in the indicated time limit.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
PO 00000
Frm 00008
Fmt 4700
Sfmt 4700
on the determination of the cost to the
public.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow FAA policies.
Any such differences are highlighted in
a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect
101 products of U.S. registry.
We estimate that 85 products of U.S.
registry will require the modification
and that it will take about 9.5 workhours per product to comply with the
modification requirements of this AD.
The average labor rate is $85 per workhour. Required parts will cost about
$1,550 per product.
Based on these figures, we estimate
the cost of the modification requirement
of this AD on U.S. operators to be
$200,387.50, or $2,357.50 per product.
We estimate that 101 products of U.S.
registry will require an inspection for
sealant application. We estimate it will
take .5 hour to comply with the
inspection requirements of this AD.
Based on these figures, we estimate
the cost of the inspection for the sealant
application requirement of this AD on
U.S. operators to be $4,292.50, or $42.50
per product.
In addition, we estimate that any
necessary follow-on actions will take
about 1.5 work-hours and require parts
costing $50, for a cost of $177.50 per
product. We have no way of
determining the number of products
that may need these actions.

Federal Register / Vol. 76, No. 162 / Monday, August 22, 2011 / Rules and Regulations
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 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.

the following new AD:
■
2011–17–15 Embraer—Empresa Brasileira
de Aeronautica S.A.: Amendment 39–
16779; Docket No. FAA–2011–0088;
Directorate Identifier 2010–CE–072–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective September 26, 2011.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the following
airplanes, certificated in any category:
(1) Group I airplanes:
Empresa Brasileira de Aeronautica S.A.
(EMBRAER) EMB–500 airplanes, serial
numbers 50000005 through 50000119,
50000121 through 50000130, 50000132
through 50000134, 50000136, 50000137,
50000139, 50000141 through 50000158,
50000160 through 50000162, 50000164,
50000165, 50000167 through 50000175,
50000177, and 50000178, that are equipped

number (P/N) C–100117–2 and cover plates
P/N 500–01702–401 and/or P/N 500–01702–
402.
(2) Group II airplanes:
Empresa Brasileira de Aeronautica S.A.
(EMBRAER) EMB–500 airplanes, serial
numbers 50000005 through 50000217,
50000219 through 50000221, and 50000226.
Note 1: In-production effectivity—Empresa
Brasileira de Aeronautica S.A. (EMBRAER)
EMB–500 airplanes, serial numbers
500000218, 50000222 through 50000225,
50000227, and on, have incorporated the
actions of this AD at the factory and are not
included in the applicability of this AD.
Subject
(d) Air Transport Association of America
(ATA) Code 27: Flight Controls.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
It has been found that moisture may
accumulate and freeze, under certain
conditions, in the gap between the AOA vane
PO 00000
Frm 00009
Fmt 4700
Sfmt 4700
52221
base assembly and the stationary ring of the
sensor’s body. If freezing occurs both AOA
sensors may get stuck and the Stall Warning
Protection System (SWPS) will be no longer
effective without alerting. This may result in
inadvertent aerodynamic stall and loss of
controllability of the airplane.
Since this condition may occur in other
airplanes of the same type and affects flight
safety, a corrective action is required. Thus,
sufficient reason exists to request compliance
with this AD in the indicated time limit.
The MCAI requires replacement of both
Angle of Attack (AOA) sensors and cover
plates, inspection of the sensor area, and, if
needed, application of sealant between the
AOA covers and the AOA sensors.
Actions and Compliance
(f) Unless already done, do the following
actions:
(1) For group I airplanes: Within 300 hours
time-in-service (TIS) after the effective date
of this AD or within 12 months after the
effective date of this AD, whichever comes
first, do the following actions following part
I of PHENOM Service Bulletin SB No.: 500–
27–0006, Revision No.: 02, dated January 14,
2011:
(i) Replace the left hand (LH) and the right
hand (RH) AOA sensors P/N C–100117–2
with LH and RH AOA sensors P/N C–
100117–3.
(ii) Replace the LH cover plate P/N 500–
01702–401 and the RH cover plate P/N 500–
01702–402 with LH cover plate P/N 500–
01702–403 and RH cover plate P/N 500–
01702–404.
(iii) If, before the effective date of this AD,
the replacement actions required in
paragraphs (f)(1)(i) and (f)(1)(ii) of this AD
have already been done following PHENOM
Service Bulletin SB No.: 500–27–0006, dated
September 2, 2010, and/or PHENOM Service
Bulletin SB No.: 500–27–0006, Revision No.:
01, dated November 29, 2010, we will allow
‘‘unless already done’’ credit for corrective
actions already done.
(2) For group I and group II airplanes:
Within 300 hours TIS after the effective date
of this AD or within 12 months after the
effective date of this AD, whichever comes
first, inspect the interface between the AOA
covers and the AOA sensors, and, if the
sealant is missing, clean the areas and apply
new sealant following part II of PHENOM
Service Bulletin SB No.: 500–27–0006,
Revision No.: 02, dated January 14, 2011.
FAA AD Differences
Note 2: This AD differs from the MCAI
and/or service information as follows: No
differences.
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, Standards Office,
FAA, has the authority to approve AMOCs
for this AD, if requested using the procedures
found in 14 CFR 39.19. Send information to

using any approved AMOC on any airplane
to which the AMOC applies, notify your
appropriate principal inspector (PI) in the
FAA Flight Standards District Office (FSDO),
or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement
in this AD to obtain corrective actions from
a manufacturer or other source, use these
actions if they are FAA-approved. Corrective
actions are considered FAA-approved if they
are approved by the State of Design Authority
(or their delegated agent). You are required
to assure the product is airworthy before it
is returned to service.

14 CFR part 39 to include an AD that
would apply to the specified products.
That supplemental NPRM was
published in the Federal Register on
April 6, 2011 (76 FR 18957). That
supplemental NPRM proposed to
correct an unsafe condition for the
specified products. The MCAI states:
Several cases have been reported of cracks

This [Canadian] directive mandates
inspection, repair (if necessary) and
reinforcement of the transcowl assemblies.
The loss of an acoustic panel during
rejected take-off or emergency landing
load conditions could leave debris on
the runway. This debris, if not removed,
creates an unsafe condition for other
airplanes during take-off or landing, as
those airplanes could impact debris on
the runway and sustain damage. The
inspection is a detailed visual
inspection of the outboard edge of the
transcowl joint extrusion for evidence of
cracking. The repair consists of doing an
eddy current or liquid penetrant
inspection for cracking, and depending
on the results, either removing the
affected joint extrusion area and
replacing with packers, or contacting
Bombardier for repair instructions and

26959). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
It has been found that moisture may accumulate and freeze, under
certain conditions, in the gap between the AOA vane base assembly
and the stationary ring of the sensor's body. If freezing occurs
both AOA sensors may get stuck and the Stall Warning Protection
System (SWPS) will be no longer effective without alerting. This may
result in inadvertent aerodynamic stall and loss of controllability
of the airplane.
Since this condition may occur in other airplanes of the same
type and affects flight safety, a corrective action is required.
Thus, sufficient reason exists to request compliance with this AD in
the indicated time limit.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect 101 products of U.S. registry.
We estimate that 85 products of U.S. registry will require the
modification and that it will take about 9.5 work-hours per product to
comply with the modification requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $1,550 per
product.
Based on these figures, we estimate the cost of the modification
requirement of this AD on U.S. operators to be $200,387.50, or
$2,357.50 per product.
We estimate that 101 products of U.S. registry will require an
inspection for sealant application. We estimate it will take .5 hour to
comply with the inspection requirements of this AD.
Based on these figures, we estimate the cost of the inspection for
the sealant application requirement of this AD on U.S. operators to be
$4,292.50, or $42.50 per product.
In addition, we estimate that any necessary follow-on actions will
take about 1.5 work-hours and require parts costing $50, for a cost of
$177.50 per product. We have no way of determining the number of
products that may need these actions.

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 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.
Examining the AD Docket
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 the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.

Applicability
(c) This AD applies to the following airplanes, certificated in
any category:
(1) Group I airplanes:
Empresa Brasileira de Aeronautica S.A. (EMBRAER) EMB-500
airplanes, serial numbers 50000005 through 50000119, 50000121
through 50000130, 50000132 through 50000134, 50000136, 50000137,
50000139, 50000141 through 50000158, 50000160 through 50000162,
50000164, 50000165, 50000167 through 50000175, 50000177, and
50000178, that are equipped with Angle of Attack (AOA) sensors, part
number (P/N) C-100117-2 and cover plates P/N 500-01702-401 and/or P/
N 500-01702-402.
(2) Group II airplanes:
Empresa Brasileira de Aeronautica S.A. (EMBRAER) EMB-500
airplanes, serial numbers 50000005 through 50000217, 50000219
through 50000221, and 50000226.
Note 1: In-production effectivity--Empresa Brasileira de
Aeronautica S.A. (EMBRAER) EMB-500 airplanes, serial numbers
500000218, 50000222 through 50000225, 50000227, and on, have
incorporated the actions of this AD at the factory and are not
included in the applicability of this AD.
Subject
(d) Air Transport Association of America (ATA) Code 27: Flight
Controls.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
It has been found that moisture may accumulate and freeze, under
certain conditions, in the gap between the AOA vane base assembly
and the stationary ring of the sensor's body. If freezing occurs
both AOA sensors may get stuck and the Stall Warning Protection
System (SWPS) will be no longer effective without alerting. This may
result in inadvertent aerodynamic stall and loss of controllability
of the airplane.
Since this condition may occur in other airplanes of the same
type and affects flight safety, a corrective action is required.
Thus, sufficient reason exists to request compliance with this AD in
the indicated time limit.
The MCAI requires replacement of both Angle of Attack (AOA) sensors
and cover plates, inspection of the sensor area, and, if needed,
application of sealant between the AOA covers and the AOA sensors.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) For group I airplanes: Within 300 hours time-in-service
(TIS) after the effective date of this AD or within 12 months after
the effective date of this AD, whichever comes first, do the
following actions following part I of PHENOM Service Bulletin SB
No.: 500-27-0006, Revision No.: 02, dated January 14, 2011:
(i) Replace the left hand (LH) and the right hand (RH) AOA
sensors P/N C-100117-2 with LH and RH AOA sensors P/N C-100117-3.
(ii) Replace the LH cover plate P/N 500-01702-401 and the RH
cover plate P/N 500-01702-402 with LH cover plate P/N 500-01702-403
and RH cover plate P/N 500-01702-404.
(iii) If, before the effective date of this AD, the replacement
actions required in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD
have already been done following PHENOM Service Bulletin SB No.:
500-27-0006, dated September 2, 2010, and/or PHENOM Service Bulletin
SB No.: 500-27-0006, Revision No.: 01, dated November 29, 2010, we
will allow ``unless already done'' credit for corrective actions
already done.
(2) For group I and group II airplanes: Within 300 hours TIS
after the effective date of this AD or within 12 months after the
effective date of this AD, whichever comes first, inspect the
interface between the AOA covers and the AOA sensors, and, if the
sealant is missing, clean the areas and apply new sealant following
part II of PHENOM Service Bulletin SB No.: 500-27-0006, Revision
No.: 02, dated January 14, 2011.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service
information as follows: No differences.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
