Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2011– 0191, dated September 30, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Several occurrences have been reported of incorrect re-installation of rear cockpit securing rope for the headrest of the rear seat during maintenance. In one of these occurrences, the aeroplane suffered an accident. The technical investigations following this accident have revealed that the rear cockpit headrest securing rope was too long, which caused the rear seat to interfere with the control stick of the aeroplane. This condition if not detected and corrected, could lead to loss of control of the aeroplane. To address this unsafe condition, DG Flugzeugbau have developed a modification to be accomplished in accordance with the Working Instruction No. 1 for Technical Note (TN) 348/20 in issue 3, dated 13 September 2011, for the English language version and in issue 2, dated 22 October 2008, for the German language version (English version revised at issue 3 to correct a translation discrepancy), which aims to prevent wrong re-installation of the headrest securing rope. TN 500/05 embodies this Working Instruction. Frm 00010 Fmt 4702 Sfmt 4702 For the reasons described above, this AD requires a one-time inspection of the length of the rear cockpit headrest securing rope and, in case of discrepancy, readjustment of the length. In addition, this AD requires the installation of a modified headrest securing rope with snap hook. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information SUPPLEMENTARY INFORMATION: PO 00000 76331 DG Flugzeugbau GmbH has issued Technical Note No. 500/05, dated September 19, 2011, and Working Instruction No. 1 for TN348/20, Issue 3, dated September 13, 2011. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of the Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This Proposed 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 proposed 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 proposed AD. Costs of Compliance We estimate that this proposed AD will affect 14 products of U.S. registry. We also estimate that it would take about 2.5 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $1,088 per product. Based on these figures, we estimate the cost of the proposed AD on U.S. E:\FR\FM\07DEP1.SGM 07DEP1 76332 Federal Register / Vol. 76, No. 235 / Wednesday, December 7, 2011 / Proposed Rules operators to be $18,207 or $1,300.50 per product. In addition, we estimate that any necessary follow-on actions would take about 0.5 work-hour, for a cost of $42.50 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. emcdonald on DSK5VPTVN1PROD with PROPOSALS Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Is not a ‘‘significant rule’’ under the 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, VerDate Mar<15>2010 16:21 Dec 06, 2011 Jkt 226001 the FAA proposes to amend 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: DG Flugzeugbau GmbH: Docket No. FAA– 2011–1342; Directorate Identifier 2011– CE–038–AD.

SUPPLEMENTARY INFORMATION: Authority Title 49 of the United States Code, section 40103 vests the Administrator with broad authority to regulate the safe and efficient use of the navigable airspace. The Administrator is authorized to issue rules and regulations to govern the flight, navigation, protection, and identification of aircraft for the protection of persons and property on the ground, and for the efficient use of the navigable airspace (49 U.S.C. 40103(b)). The Administrator also is authorized under § 44701(a)(5) to promote safe flight of civil aircraft in air commerce by prescribing regulations and minimum standards for other PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 76333 practices, methods, and procedures necessary for safety in air commerce and national security. Background During the past decade, there has been an increased focus on the use of clean renewable energy resources, including wind energy. The FAA has been approached by various entities, including manufacturers, scientists, engineers, and advocacy groups representing the wind energy community, who are researching the use of more sustained and consistent winds at higher altitudes where conventional ground-based wind turbines cannot reach. As part of their research, the energy community is examining various concepts for system designs to harness high altitude winds as a potential source of energy. Airborne Wind Energy Systems (AWES) are described broadly as mechanical devices that are moored to the ground, via a tether or cabling component, for the purpose of capturing the fluid stream kinetic energy of winds. The kinetic energy captured by the device is then utilized in various fashions to generate electricity. In one option, the wind energy is immediately converted into consumable power, at the system component keeping the system aloft, and then transferred to the ground by a mechanical tether, cabling conductor, or other method. In another option, the combination of the wind, the aloft device, and the mooring cables are systematically utilized to drive an electrical generator located on the ground. The basic overall components that comprise various AWESs are fairly similar in concept, however, the technologies and the specific devices that keep them aloft differ dramatically. Such devices have leveraged on similar engineering designs that apply to kites, balloons, kytoons, aircraft wings, aircraft, airfoils, as well as others.1 Although some of these AWES components could be covered by 14 CFR part 101, Moored balloons, kites, amateur rockets and unmanned free balloons, some conceptual designs include hybrid concepts or utilize new innovative techniques that are not as easily classifiable. For example, the FAA identified some AWESs employing ‘‘balloon-like’’ design structures with 1 14 CFR 1.1 defines a balloon as a ‘‘lighter-thanair aircraft that is not engine driven, and that sustains flight through the use of either gas buoyancy or an airborne heater,’’ and defines a kite as a ‘‘framework, covered with paper, cloth, metal, or other material, intended to be flown at the end of a rope or cable, and having as its only support the force of the wind moving past its surfaces.’’ E:\FR\FM\07DEP1.SGM 07DEP1

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2011-0191, dated September 30, 2011 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Several occurrences have been reported of incorrect re-
installation of rear cockpit securing rope for the headrest of the 
rear seat during maintenance. In one of these occurrences, the 
aeroplane suffered an accident. The technical investigations 
following this accident have revealed that the rear cockpit headrest 
securing rope was too long, which caused the rear seat to interfere 
with the control stick of the aeroplane.
    This condition if not detected and corrected, could lead to loss 
of control of the aeroplane.
    To address this unsafe condition, DG Flugzeugbau have developed 
a modification to be accomplished in accordance with the Working 
Instruction No. 1 for Technical Note (TN) 348/20 in issue 3, dated 
13 September 2011, for the English language version and in issue 2, 
dated 22 October 2008, for the German language version (English 
version revised at issue 3 to correct a translation discrepancy), 
which aims to prevent wrong re-installation of the headrest securing 
rope. TN 500/05 embodies this Working Instruction.
    For the reasons described above, this AD requires a one-time 
inspection of the length of the rear cockpit headrest securing rope 
and, in case of discrepancy, readjustment of the length. In 
addition, this AD requires the installation of a modified headrest 
securing rope with snap hook.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    DG Flugzeugbau GmbH has issued Technical Note No. 500/05, dated 
September 19, 2011, and Working Instruction No. 1 for TN348/20, Issue 
3, dated September 13, 2011. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

FAA's Determination and Requirements of the Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Differences Between This Proposed 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 proposed 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 proposed AD.

Costs of Compliance

    We estimate that this proposed AD will affect 14 products of U.S. 
registry. We also estimate that it would take about 2.5 work-hours per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $1,088 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S.

[[Page 76332]]

operators to be $18,207 or $1,300.50 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 0.5 work-hour, for a cost of $42.50 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.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

DG Flugzeugbau GmbH: Docket No. FAA-2011-1342; Directorate 
Identifier 2011-CE-038-AD.

(a) Comments Due Date

    We must receive comments by January 23, 2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to DG Flugzeugbau GmbH Models DG-500 Elan Orion 
sailplanes and DG-500M and DG-500MB powered sailplanes, all serial 
numbers, that are:
    (i) Equipped with a headrest on the rear seat; and
    (ii) certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 25: Equipment/
Furnishing.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) originated 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 incorrect re-
installation of the rear cockpit securing rope for the headrest of 
the rear seat during maintenance. We are issuing this AD to correct 
the length of the rear cockpit headrest securing rope, which if too 
long, could cause the rear seat to interfere with the control stick 
of the sailplane and could result in loss of control of the 
sailplane.

(f) Actions and Compliance

    Unless already done, do the following actions:
    (1) Within the next 30 days after the effective date of this AD, 
inspect the rear cockpit headrest securing rope to determine the 
length. Do the inspection as specified in Instruction No. 2 of DG 
Flugzeugbau GmbH Technical Note No. 500/05, dated September 19, 
2011.
    (i) If the length of the rear cockpit headrest securing rope is 
more than 450 millimeters (mm) or less than 400 mm, before further 
flight, adjust the length of the rear cockpit headrest securing rope 
to a length between 400 mm and 450 mm as shown in Sketch 2 of DG 
Flugzeugbau GmbH Working Instruction No. 1 for TN348/20, Issue 3, 
dated September 13, 2011. After doing the adjustment, do the action 
required in paragraph (f)(2) of this AD.
    (ii) If the length of the rear cockpit headrest securing rope is 
between 400 mm and 450 mm, do the action required in paragraph 
(f)(2) of this AD.
    (2) Within 3 months after the effective date of this AD, replace 
the rear cockpit headrest securing rope with a rear cockpit headrest 
securing rope with a snap hook. Do the replacement following DG 
Flugzeugbau GmbH Working Instruction No. 1 for TN348/20, Issue 3, 
dated September 13, 2011, as specified in Instruction No. 3 of DG 
Flugzeugbau GmbH Technical Note No. 500/05, dated September 19, 
2011.
    (3) Replacement of the rear cockpit headrest securing rope with 
a rear cockpit headrest securing rope with a snap hook done before 
the effective date of this AD following DG Flugzeugbau GmbH Working 
Instruction No. 1 for TN348/20, Issue 2, is considered acceptable 
for compliance with paragraph (f)(2) of this AD.

(g) FAA AD Differences

    Note:  This AD differs from the MCAI and/or service information 
as follows: No differences.

(h) Other FAA AD Provisions
