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.

SUPPLEMENTARY INFORMATION: History On June 28, 2010, the FAA published in the Federal Register a NPRM to establish Class E airspace extending upward from 700 feet above the surface at Panguitch, UT (75 FR 36585). The FAA agreed with a comment received to also expand controlled airspace from 1,200 feet, and on October 18, 2010, published in the Federal Register a supplemental notice of proposed rulemaking to expand the proposed Class E 700 foot airspace to include Class E airspace from 1,200 feet above the surface at Panguitch, UT (75 FR 63730). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the supplemental proposal to the FAA. The FAA received one comment to an increase to the southern boundary of the 1,200′AGL airspace description. The FAA found merit in this comment, and will incorporate this change in the final rule. With the exception of editorial changes and the changes described above, this rule is the same as that proposed in the NPRM and SNPRM. 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 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 establishing Class E airspace extending upward from 700 feet above the surface, at Panguitch Municipal Airport, to accommodate IFR aircraft executing new RNAV GPS Standard Instrument Approach Procedures at the airport. This action is necessary for the safety and management of IFR operations at the airport. The FAA has determined this regulation only involves an established PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 Date December 1, 2010. 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 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 Panguitch Municipal Airport, Panguitch, UT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD requires repetitively inspecting the
cockpit heated windshields for damage and replacing damaged
windshields. This AD was prompted by reports from the windshield
manufacturer of inner glass ply fracture. We are issuing this AD to
detect and correct damage to the cockpit heated windshield, which could
result in failure of the windshield with consequent rapid cabin
decompression and loss of control of the airplane.

DATES: This AD is effective January 24, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publication listed in the AD as of January 24,
2011.

SUPPLEMENTARY INFORMATION:

Discussion

We received reports from the windshield manufacturer of inner glass
ply fractures found on 19 windshields over a 32-month period. As a
result of the fractures, a windshield on one of the affected airplanes
was reported to have failed completely.
This condition, if not corrected, could result in failure of the
cockpit heated windshield, causing rapid cabin decompression and loss
of control of the airplane.

Relevant Service Information

We reviewed M7 Aerospace Service Bulletins 26-56-001, 226-56-011,
227-56-012, and CC7-56-009, all dated December 1, 2010. These service
bulletins describe procedures for repetitively inspecting the cockpit
heated windshield for damage and replacing damaged windshields.

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 accomplishing the actions specified in the service
information described previously, except as discussed under
``Differences Between the AD and the Service Information.''

Interim Action

We consider this AD interim action. The design approval holder is
currently developing a modification that will address the unsafe
condition identified in this AD. Once this modification is developed,
approved, and available, we might consider additional rulemaking.

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 this
condition could result in failure of the cockpit windshield. This
failure could lead to rapid cabin decompression and loss of control of
the airplane. 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

Costs of Compliance

We estimate that this AD affects 362 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Action Labor cost Parts cost Cost per product Cost on U.S. operators

We estimate the following costs to do any necessary replacements
that would be required based on the results of the inspection. We have
no way of determining the number of aircraft that might need this
replacement:

On-Condition Costs

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.
