Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. That NPRM was published in the Federal Register on September 6, 2005 (70 FR 52947). That NPRM proposed to require modifying the wiring of the starter-generator terminal block. Conclusion Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. This AD affects about 57 airplanes of U.S. registry. The actions take about 10 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of this AD for U.S. operators is $37,050, or $650 per airplane. Support for the NPRM and Request for Further Information About Alternative Methods of Compliance (AMOCs) One commenter concurs with our decision to act on the manufacturer’s proposed solution to the unsafe condition. The commenter also requests information about what kinds of AMOCs we will find acceptable for compliance with the actions required by the final rule. It is difficult to describe the specific types of AMOCs that we will find acceptable for compliance with this AD because AMOCs vary according to the airplane operator, and cannot be predicted until we receive a written request. In general, AMOCs are different approaches or techniques that are not specified in an AD that can, after our approval, be used to correct an unsafe condition on an aircraft or aircraft product. The AMOC must be acceptable to accomplish the intent of the AD, provide an acceptable level of safety, and have sufficient technical justification so that we can evaluate the request. For example, a compliance time that differs from the requirements of the AD can be approved if the revised time period in combination with other mitigating actions provides an acceptable level of safety for the requirements of the AD. The purpose of AMOCs is to ensure the most efficient method of compliance for individual operators and also to eliminate the need for constant AD revisions when acceptable methods are developed for AD compliance. It is not necessary to change the final rule in this regard. Clarification of AMOC Paragraph We have revised this action to clarify the appropriate procedure for notifying the principal inspector before using any VerDate Aug<31>2005 16:47 Dec 12, 2005 Jkt 208001 We have carefully reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the change described previously. We have determined that this change will neither increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance 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 Frm 00032 Fmt 4700 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

No. 3145] Standard Instrument Approach Procedures; Miscellaneous Amendments Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: SUMMARY: This amendment amends Standard Instrument Approach Procedures (SIAPs) for operations at certain airports. These regulatory actions are needed because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, addition of new obstacles, or changes in air traffic requirements. These changes are VerDate Aug<31>2005 17:40 Dec 12, 2005 Jkt 208001 designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports. DATES: This rule is effective December 13, 2005. The compliance date for each SIAP is specified in the amendatory provisions. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of December 13, 2005. ADDRESSES: Availability of matter incorporated by reference in the amendment is as follows: For Examination: 1.

Pate, Flight Procedure Standards Branch (AFS–420), Flight Technologies and Programs Division, Flight Standards Service, Federal Aviation Administration, Mike Monroney Aeronautical Center, 6500 South MacArthur Blvd, Oklahoma City, OK 73169 (Mail Address: P.O. Box 25082 Oklahoma City, OK 73125) telephone: (405) 954–4164. SUPPLEMENTARY INFORMATION: This amendment to Title 14, Code of Federal Regulations, part 97 (14 CFR part 97) amends Standard Instrument Approach Procedures (SIAPs). The complete regulatory description of each SIAP is contained in the appropriate FAA Form PO 00000 Frm 00033 Fmt 4700 Sfmt 4700 73585 8260, as modified by the the National Flight Data Center (FDC)/Permanent Notice to Airmen (P-NOTAM), which is incorporated by reference in the amendment under 5 U.S.C. 552(a), 1 CFR part 51, and § 97.20 of the Code of Federal Regulations. Materials incorporated by reference are available for examination or purchase as stated above. The large number of SIAPs, their complex nature, and the need for a special format make their verbatim publication in the Federal Register expensive and impractical. Further, airmen do not use the regulatory text of the SIAPs, but refer to their graphic depiction on charts printed by publishers of aeronautical materials. Thus, the advantages of incorporation by reference are realized and publication of the complete description of each SIAP contained in FAA form documents is unnecessary. The provisions of this amendment state the affected CFR sections, with the types and effective dates of the SIAPs. This amendment also identifies the airport, its location, the procedure identification and the amendment number. The Rule This amendment to 14 CFR part 97 is effective upon publication of each separate SIAP as amended in the transmittal. For safety and timeliness of change considerations, this amendment incorporates only specific changes contained for each SIAP as modified by FDC/P–NOTAMs. The SIAPs, as modified by FDC P– NOTAM, and contained in this amendment are based on the criteria contained in the U.S. Standard for Terminal Instrument Procedures (TERPS). In developing these chart changes to SIAPs, the TERPS criteria were applied to only these specific conditions existing at the affected airports. All SIAP amendments in this rule have been previously issued by the FAA in a FDC NOTAM as an emergency action of immediate flight safety relating directly to published aeronautical charts. The circumstances which created the need for all these SIAP amendments requires making them effective in less than 30 days. Further, the SIAPs contained in this amendment are based on the criteria contained in TERPS. Because of the close and immediate relationship between these SIAPs and safety in air commerce, I find that notice and public procedure before adopting these SIAPs are impracticable and contrary to the public interest and, where applicable, that good cause exists for making these SIAPs effective in less than 30 days.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to all BAE Systems 
(Operations) Limited (Jetstream) Model 4101 airplanes. That NPRM was 
published in the Federal Register on September 6, 2005 (70 FR 52947). 
That NPRM proposed to require modifying the wiring of the starter-
generator terminal block.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Support for the NPRM and Request for Further Information About 
Alternative Methods of Compliance (AMOCs)

    One commenter concurs with our decision to act on the 
manufacturer's proposed solution to the unsafe condition. The commenter 
also requests information about what kinds of AMOCs we will find 
acceptable for compliance with the actions required by the final rule.
    It is difficult to describe the specific types of AMOCs that we 
will find acceptable for compliance with this AD because AMOCs vary 
according to the airplane operator, and cannot be predicted until we 
receive a written request. In general, AMOCs are different approaches 
or techniques that are not specified in an AD that can, after our 
approval, be used to correct an unsafe condition on an aircraft or 
aircraft product. The AMOC must be acceptable to accomplish the intent 
of the AD, provide an acceptable level of safety, and have sufficient 
technical justification so that we can evaluate the request. For 
example, a compliance time that differs from the requirements of the AD 
can be approved if the revised time period in combination with other 
mitigating actions provides an acceptable level of safety for the 
requirements of the AD. The purpose of AMOCs is to ensure the most 
efficient method of compliance for individual operators and also to 
eliminate the need for constant AD revisions when acceptable methods 
are developed for AD compliance.
    It is not necessary to change the final rule in this regard.

Clarification of AMOC Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, and determined that air safety and the public 
interest require adopting the AD with the change described previously. 
We have determined that this change will neither increase the economic 
burden on any operator nor increase the scope of the AD.

Costs of Compliance

    This AD affects about 57 airplanes of U.S. registry. The actions 
take about 10 work hours per airplane, at an average labor rate of $65 
per work hour. Based on these figures, the estimated cost of this AD 
for U.S. operators is $37,050, or $650 per airplane.

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.
