SUPPLEMENTARY INFORMATION: Discussion On February 14, 2013, we issued AD 2013–04–08, amendment 39–17365 (78 FR 14160, March 5, 2013), for all Diamond Aircraft Industries GmbH Models HK 36 R, HK 36 TS, and HK 36 TTS powered gliders. That AD requires replacement of the elevator bell crank assembly and elevator bell crank mount. That AD resulted from installation of an unsuitable self-locking nut on the bell crank of the elevator push rod that can cause failure of the elevator, resulting in loss of control. We issued that AD to require actions to address the unsafe condition on these products. Actions Since AD Was Issued Since we issued AD 2013–04–08 (78 FR 14160, March 5, 2013), it was determined that Model H–36 airplanes do not have the elevator control and bellcrank assembly part numbers associated with the unsafe condition of this AD. Since Model H–36 airplanes do not have the unsafe condition, it is not necessary or possible for those airplanes to comply with this AD, so we are removing the Model H–36 from the Applicability section. Relevant Service Information We reviewed Diamond Aircraft Industries GmbH Mandatory Service Bulletin MSB 36–108, dated February 28, 2012; and Diamond Aircraft E:\FR\FM\06MYR1.SGM 06MYR1 26242 Federal Register / Vol. 78, No. 87 / Monday, May 6, 2013 / Rules and Regulations Industries GmbH Work Instruction WI– MSB 36–108, dated February 28, 2012. The service information describes procedures for replacement of the elevator bell crank assembly and elevator bell crank mount. FAA’s Determination We are issuing this AD because we evaluated all the relevant information and determined it is not necessary or possible for Diamond Aircraft Industries GmbH Model H–36 airplanes to comply with the previous AD. AD Requirements This AD requires accomplishing the actions specified in the service information described previously. pmangrum on DSK3VPTVN1PROD with RULES 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 the Diamond Model H–36 does not have the same elevator control and bell crank assembly. It is not necessary and not possible for these powered gliders to comply with the AD action items. Therefore, we find that notice and opportunity for prior public comment are unnecessary 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 we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA–2012–1172 and directorate identifier 2012–CE–040–AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We 15:01 May 03, 2013 Jkt 229001 Costs of Compliance We estimate that this AD will affect 25 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts would cost about $352 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $13,050, or $522 per product. Authority for This Rulemaking Change to Existing AD This AD would retain all requirements of 2013–04–08 (78 FR 14160, March 5, 2013), but decrease the Applicability by removing Model H–36. VerDate Mar<15>2010 will also post a report summarizing each substantive verbal contact we receive about this AD. 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.

ACTION: Final rule. AGENCY: This action amends Class E Airspace at Easton, PA, as the Allentown VORTAC has been decommissioned and new Standard Instrument Approach Procedures have been developed at Braden Airpark. This action enhances the safety and management of Instrument Flight Rules (IFR) operations at the airport. This action also recognizes the airport’s name change and updates the geographic coordinates of the airport. DATES: Effective 0901 UTC, June 27, 2013. The Director of the Federal Register approves this incorporation by reference action under title 1, Code of Federal Regulations, part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments. SUMMARY: John Fornito, Operations Support Group, Eastern Service Center, Federal Aviation Administration, P.O. Box 20636, Atlanta, Georgia 30320; telephone (404) 305–6364. SUPPLEMENTARY INFORMATION: FOR FURTHER INFORMATION CONTACT: History On January 24, 2013, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to amend Class E airspace at Easton, PA (78 FR 5152) Docket No. FAA–2012– 0394. Interested parties were invited to PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 26243 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 7400.9W dated August 8, 2012, and effective September 15, 2012, 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 the Order. The Rule This amendment to Title 14, Code of Federal Regulations (14 CFR) part 71 amends the Class E airspace extending upward from 700 feet above the surface at Easton, PA to accommodate the new Standard Instrument Approach Procedures developed for Braden Airpark. The Allentown VORTAC has been decommissioned, and the VOR/ DME approach cancelled. The controlled airspace area is increased to within an 8.2-mile radius of the airport due to terrain in the surrounding area. Also, the airport name is changed from Easton Airport to Braden Airpark, and the geographic coordinates of the airport are adjusted to coincide with the FAA’s aeronautical database. Also, the sentence in the regulatory text referencing the effectiveness of the airspace from sunrise to sunset, daily, is removed. Except for editorial changes and the changes noted above, this rule is the same as published in the NPRM. 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, is non-controversial and unlikely to result in adverse or negative comments. It, therefore, (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 United States Code. 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. This rulemaking is E:\FR\FM\06MYR1.SGM 06MYR1

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are revising an airworthiness directive (AD) for certain 
Diamond Aircraft Industries GmbH Models HK 36 R, HK 36 TS, and HK 36 
TTS powered gliders. AD 2013-04-08 required replacement of each 
elevator bell crank assembly and elevator bell crank mount. This AD 
retains the actions of AD 2013-04-08 but decreases gliders in the 
Applicability by removing the Model H-36 from the Applicability. This 
AD was prompted by reports of installation of an unsuitable self-
locking nut on the bell crank of the elevator push rod that can cause 
failure of the elevator, resulting in loss of control. We are issuing 
this AD to correct the unsafe condition on these products.

DATES: This final rule is effective May 6, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 9, 2013

SUPPLEMENTARY INFORMATION: 

Discussion

    On February 14, 2013, we issued AD 2013-04-08, amendment 39-17365 
(78 FR 14160, March 5, 2013), for all Diamond Aircraft Industries GmbH 
Models HK 36 R, HK 36 TS, and HK 36 TTS powered gliders. That AD 
requires replacement of the elevator bell crank assembly and elevator 
bell crank mount. That AD resulted from installation of an unsuitable 
self-locking nut on the bell crank of the elevator push rod that can 
cause failure of the elevator, resulting in loss of control. We issued 
that AD to require actions to address the unsafe condition on these 
products.

Actions Since AD Was Issued

    Since we issued AD 2013-04-08 (78 FR 14160, March 5, 2013), it was 
determined that Model H-36 airplanes do not have the elevator control 
and bellcrank assembly part numbers associated with the unsafe 
condition of this AD. Since Model H-36 airplanes do not have the unsafe 
condition, it is not necessary or possible for those airplanes to 
comply with this AD, so we are removing the Model H-36 from the 
Applicability section.

Relevant Service Information

    We reviewed Diamond Aircraft Industries GmbH Mandatory Service 
Bulletin MSB 36-108, dated February 28, 2012; and Diamond Aircraft

[[Page 26242]]

Industries GmbH Work Instruction WI-MSB 36-108, dated February 28, 
2012. The service information describes procedures for replacement of 
the elevator bell crank assembly and elevator bell crank mount.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined it is not necessary or possible for Diamond 
Aircraft Industries GmbH Model H-36 airplanes to comply with the 
previous AD.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously.

Change to Existing AD

    This AD would retain all requirements of 2013-04-08 (78 FR 14160, 
March 5, 2013), but decrease the Applicability by removing Model H-36.

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 the 
Diamond Model H-36 does not have the same elevator control and bell 
crank assembly. It is not necessary and not possible for these powered 
gliders to comply with the AD action items. Therefore, we find that 
notice and opportunity for prior public comment are unnecessary 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 we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
the docket number FAA-2012-1172 and directorate identifier 2012-CE-040-
AD at the beginning of your comments. We specifically invite comments 
on the overall regulatory, economic, environmental, and energy aspects 
of this AD. We will consider all comments received by the closing date 
and may amend this AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD will affect 25 products of U.S. registry. 
We also estimate that it would take about 2 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts would cost about $352 per product.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $13,050, or $522 per product.

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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends part 39 of the Federal Aviation 
Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing airworthiness directive (AD) 
2013-04-08 (78 FR 14160, March 5, 2013) and adding the following new 
AD:

2013-04-08 R1 Diamond Aircraft Industries GmbH: Amendment 39-17447; 
Docket No. FAA-2012-1172; Directorate Identifier 2012-CE-040-AD.

(a) Effective Date

    This AD is effective May 6, 2013.

(b) Affected ADs

    This AD revises AD 2013-04-08 (78 FR 14160, March 5, 2013), 
Amendment 39-17365.

(c) Applicability

    This AD applies to the following Diamond Aircraft Industries 
GmbH models and serial number (S/N) powered gliders, certificated in 
any category: HK 36 R powered gliders, S/Ns 36.300 through 36.414; 
HK 36 TS powered gliders, S/Ns 36.415 and 36.416; and HK 36 TTS 
powered gliders, S/N 36.393.

 (d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) Code 27: Flight Controls.

(e) Unsafe Condition

    This AD was prompted by reports of installation of an unsuitable 
self-locking nut on the bell crank of the elevator push rod that can 
cause failure of the elevator, resulting in loss of control. We are 
issuing this revised AD because we evaluated all the relevant 
information and determined it is not necessary or possible for the 
Diamond Aircraft Industries GmbH Model H-36 to comply with the 
previous AD. Installation of an unsuitable self-locking nut on the 
bell crank of the elevator push rod that can cause failure of the 
elevator, resulting in loss of control.

(f) Actions and Compliance

    Unless already done, do the following actions specified in 
paragraphs (f)(1) and (f)(2) of this AD following Diamond Aircraft
