Pitot/AOA Probes (Part Numbers 100435–39, 100435–39–001, 100435–40, and 100435–40–001) Federal Aviation Administration (FAA), DOT. ACTION: Final rule; request for comments. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Harco Labs, Inc. part numbers 100435– 39, 100435–39–001, 100435–40, and 100435–40–001 pitot/angle of attack (AOA) probes installed on, but not limited to Eclipse Aviation Inc. Model EA500 airplanes. This AD requires you to incorporate information into the Limitations section of the airplane flight manual (AFM) that will allow operation only under day visual flight rules (VFR) and allow only a VFR flight plan. This AD also requires you to test the pitot/ AOA probes for heater performance and replace the pitot/AOA probe if it fails the heater performance test. This AD results from several reports of airspeed disagree caution indication due to blockage from freezing condensation within the pitot/AOA system. We are issuing this AD to detect and correct improperly performing pitot/AOA probe heaters, which could result in blockage within the pitot/AOA system from condensation freezing with consequent incorrect indication of impact air pressure (airspeed/AOA). This blockage could lead to the stall warning becoming unreliable and the stick pusher, overspeed warning, autopilot, and yaw damper to malfunction. DATES: This AD becomes effective on September 29, 2008. On September 29, 2008, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION: Discussion We received several reports of airspeed disagree caution indication due to blockage within the pitot/AOA system from freezing condensation. We are issuing this AD to detect and correct improperly performing pitot/AOA probe heaters. This condition, if not corrected, could result in a blockage within the pitot/ AOA system from condensation freezing with consequent incorrect indication of impact air pressure (airspeed/AOA). This blockage could lead to the stall warning becoming unreliable and the stick pusher, overspeed warning, autopilot, and yaw damper to malfunction. Relevant Service Information We reviewed Harco Labs, Inc. Service Bulletin SB–34–10–10–001, Revision F, dated August 19, 2008; Harco Pitot AOA Probe Internal Tubing Heater Verification Test Procedure No. P1149, Rev: E, referenced in 8. Appendix A of Harco Labs, Inc. Service Bulletin SB– E:\FR\FM\09SER1.SGM 09SER1 52206 Federal Register / Vol. 73, No. 175 / Tuesday, September 9, 2008 / Rules and Regulations 34–10–10–001, Revision F, dated August 19, 2008; and Eclipse Aviation Alert Service Bulletin SB 500–34–019, Rev C, dated August 20, 2008. The service information describes procedures for verification of the internal tube (wedge) heater performance on pitot/AOA probes. FAA’s Determination and Requirements of This AD We are issuing this AD because we evaluated all the information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This AD requires you to incorporate information into the Limitations section of the airplane flight manual (AFM) that will allow operation only under day visual flight rules (VFR) and allow only a VFR flight plan. This AD also requires you to test the pitot/ AOA probes for heater performance and replace the pitot/AOA probe if it fails the heater performance test. FAA’s 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 the potential for the stall warning to become unreliable and the stick pusher, overspeed warning, autopilot, and yaw damper to malfunction due to blockage from condensation freezing in the pitot/AOA system compromises the continued operational safety of the airplanes. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. yshivers on PROD1PC62 with RULES Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and an opportunity for public comment. We invite you to send any written relevant data, views, or arguments regarding this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number ‘‘FAA– 2008–0955; Directorate Identifier 2008– CE–040–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the AD. We will consider all comments received by the closing date and may amend the AD in light of those comments. VerDate Aug<31>2005 15:16 Sep 08, 2008 Jkt 214001 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 concerning 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 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. Examining the AD Docket You may examine the AD docket that contains the 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.

Additional controlled airspace is necessary to support flight operations at Abbotsford Airport, BC. The FAA is taking this action to improve the safety and management of Instrument Flight Rules (IFR) operations at the request of the Canadian Government. DATES: Effective Date: 0901 UTC, November 20, 2008. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments. FOR FURTHER INFORMATION CONTACT: Richard Roberts, Federal Aviation Administration, Operations Support Group, Western Service Area, 1601 Lind Avenue, SW., Renton, WA 98057; telephone (425) 203–4517. SUPPLEMENTARY INFORMATION: This action amends Title 14 Code of Federal Regulations (14 CFR) part 71 by establishing Class E airspace at Point Roberts, WA. Additional controlled airspace is necessary to support IFR operations at Abbotsford Airport, BC. The FAA has determined that 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 that 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 of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it establishes controlled airspace at Point Roberts, WA. History List of Subjects in 14 CFR Part 71 On February 7, 2008, the FAA published in the Federal Register a notice of proposed rulemaking to establish controlled airspace at Point Roberts, WA (73 FR 7228). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9R signed August 15, 2007, and effective September 15, 2007, 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. Airspace, Incorporation by reference, Navigation (air).

Airworthiness Directives; Harco Labs, Inc. Pitot/AOA Probes (Part 
Numbers 100435-39, 100435-39-001, 100435-40, and 100435-40-001)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Harco Labs, Inc. part numbers 100435-39, 100435-39-001, 100435-
40, and 100435-40-001 pitot/angle of attack (AOA) probes installed on, 
but not limited to Eclipse Aviation Inc. Model EA500 airplanes. This AD 
requires you to incorporate information into the Limitations section of 
the airplane flight manual (AFM) that will allow operation only under 
day visual flight rules (VFR) and allow only a VFR flight plan. This AD 
also requires you to test the pitot/AOA probes for heater performance 
and replace the pitot/AOA probe if it fails the heater performance 
test. This AD results from several reports of airspeed disagree caution 
indication due to blockage from freezing condensation within the pitot/
AOA system. We are issuing this AD to detect and correct improperly 
performing pitot/AOA probe heaters, which could result in blockage 
within the pitot/AOA system from condensation freezing with consequent 
incorrect indication of impact air pressure (airspeed/AOA). This 
blockage could lead to the stall warning becoming unreliable and the 
stick pusher, overspeed warning, autopilot, and yaw damper to 
malfunction.

SUPPLEMENTARY INFORMATION:

Discussion

    We received several reports of airspeed disagree caution indication 
due to blockage within the pitot/AOA system from freezing condensation. 
We are issuing this AD to detect and correct improperly performing 
pitot/AOA probe heaters.
    This condition, if not corrected, could result in a blockage within 
the pitot/AOA system from condensation freezing with consequent 
incorrect indication of impact air pressure (airspeed/AOA). This 
blockage could lead to the stall warning becoming unreliable and the 
stick pusher, overspeed warning, autopilot, and yaw damper to 
malfunction.

Relevant Service Information

    We reviewed Harco Labs, Inc. Service Bulletin SB-34-10-10-001, 
Revision F, dated August 19, 2008; Harco Pitot AOA Probe Internal 
Tubing Heater Verification Test Procedure No. P1149, Rev: E, referenced 
in 8. Appendix A of Harco Labs, Inc. Service Bulletin SB-

[[Page 52206]]

34-10-10-001, Revision F, dated August 19, 2008; and Eclipse Aviation 
Alert Service Bulletin SB 500-34-019, Rev C, dated August 20, 2008. The 
service information describes procedures for verification of the 
internal tube (wedge) heater performance on pitot/AOA probes.

FAA's Determination and Requirements of This AD

    We are issuing this AD because we evaluated all the information and 
determined the unsafe condition described previously is likely to exist 
or develop on other products of the same type design. This AD requires 
you to incorporate information into the Limitations section of the 
airplane flight manual (AFM) that will allow operation only under day 
visual flight rules (VFR) and allow only a VFR flight plan. This AD 
also requires you to test the pitot/AOA probes for heater performance 
and replace the pitot/AOA probe if it fails the heater performance 
test.

FAA's 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 the 
potential for the stall warning to become unreliable and the stick 
pusher, overspeed warning, autopilot, and yaw damper to malfunction due 
to blockage from condensation freezing in the pitot/AOA system 
compromises the continued operational safety of the airplanes. 
Therefore, we determined that notice and opportunity for public comment 
before issuing this AD are impracticable and that good cause exists for 
making this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and an opportunity for 
public comment. We invite you to send any written relevant data, views, 
or arguments regarding this AD. Send your comments to an address listed 
under the ADDRESSES section. Include the docket number ``FAA-2008-0955; 
Directorate Identifier 2008-CE-040-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD. We will consider 
all comments received by the closing date and may amend the AD in light 
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 concerning 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 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.

Examining the AD Docket

    You may examine the AD docket that contains the 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) 647-5527) 
is located at the street address stated in the ADDRESSES section. 
Comments will be available in the AD docket shortly after receipt.
