(EMBRAER) Model EMB–500 Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). 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. E:\FR\FM\22AUR1.SGM 22AUR1 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. mstockstill on DSK4VPTVN1PROD with RULES 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.

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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding 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 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 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.

Before 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. (3) Reporting Requirements: For any reporting requirement in this AD, a Federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number. The OMB Control Number for this information collection is 2120–0056.

Airworthiness Directives; Embraer--Empresa Brasileira de 
Aeronautica S.A. (EMBRAER) Model EMB-500 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final Rule.

-----------------------------------------------------------------------

SUMMARY: 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:

    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 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.

    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.

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,

    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, 
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 ATTN: Jim Rutherford, Aerospace Engineer, FAA, Small 
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri

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.
    (3) Reporting Requirements: For any reporting requirement in 
this AD, a Federal agency may not conduct or sponsor, and a person 
is not required to respond to, nor shall a person be subject to a 
penalty for failure to comply with a collection of information 
subject to the requirements of the Paperwork Reduction Act unless 
that collection of information displays a current valid OMB Control 
Number. The OMB Control Number for this information collection is 
2120-0056. Public reporting for this collection of information is 
estimated to be approximately 5 minutes per response, including the 
time for reviewing instructions, completing and reviewing the
