Airworthiness Directives; Fiberglas-Technik Rudolf Lindner GmbH & 
Co. KG Gliders

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for 
Fiberglas-Technik Rudolf Lindner GmbH & Co. KG (type certificates 
formerly held by GROB-WERKE GMBH & CO KG and BURKHART GROB LUFT- UND 
RAUMFAHRT GmbH & CO KG) Models G102 STANDARD ASTIR III, G102 CLUB ASTIR 
III, G102 CLUB ASTIR IIIb, G103 TWIN II, G103A TWIN II ACRO, G103C TWIN 
III ACRO, and G 103 C Twin III SL gliders. This AD revises AD 2014-15-
02, which required inspection of the rudder control unit for 
installation of plastic cable pulleys and replacement of plastic cable 
pulleys with aluminum cable pulleys. This AD retains the actions of AD 
2014-15-02 but clarifies the suffixes of serial numbers (S/Ns) in 
paragraph (c) Applicability. This AD was prompted by reports of plastic 
control cable pulleys developing cracks due to aging, which could lead 
to breaking of the pulley and potentially jamming the rudder control 
unit, possibly resulting in loss of control. We are issuing this AD to 
require actions to address the unsafe condition on these products.

DATES: This final rule is effective October 24, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 27, 
2014 (79 FR 42658, July 23, 2014).
    We must receive comments on this AD by December 8, 2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    On July 14, 2014, we issued AD 2014-15-02, Amendment 39-17904 (79 
FR 42658, July 23, 2014), for GROB-WERKE GMBH & CO KG Models G102 
STANDARD ASTIR III, G102 CLUB ASTIR III, and G102 CLUB ASTIR IIIb 
gliders and BURKHART GROB LUFT--UND RAUMFAHRT GmbH & CO KG Models G103 
TWIN II, G103A TWIN II ACRO, G103C TWIN III ACRO, and G 103 C Twin III 
SL gliders. That AD required inspection of the rudder control unit for 
installation of plastic cable pulleys and replacement of plastic cable 
pulleys with aluminum cable pulleys. That AD resulted from reports of 
plastic control cable pulleys developing cracks due to aging, which 
could lead to breaking of the pulley and potentially jamming the rudder 
control unit, possibly 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 2014-15-02 (79 FR 42658, July 23, 2014), it was 
determined that to avoid any confusion regarding applicability to a 
given glider, the AD should be revised to include references to certain 
suffixes of S/Ns in paragraph (c) Applicability.

Relevant Service Information

    We reviewed Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Service 
Bulletin SB-G05, dated January 17, 2014; and Fiberglas-Technik Rudolf 
Lindner GmbH & Co. KG Instructions A/I-G05, dated January 17, 2014. The 
service information describes procedures for inspection of the rudder 
control unit for installation of plastic cable pulleys and replacement 
of plastic cable pulleys with aluminum cable pulleys.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined that to avoid any confusion about 
applicability to a given glider, AD 2014-15-02 (79 FR 42658, July 23, 
2014) should be revised to include references to certain suffixes of S/
Ns in paragraph (c) Applicability.

AD Requirements

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

Change to Existing AD

    This AD retains all requirements of AD 2014-15-02 (79 FR 42658, 
July 23, 2014), but revises paragraph (c) Applicability to include 
references to certain suffixes in referenced S/Ns of gliders.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. We received no comments on the previous AD, and this action 
only clarifies the applicability to a given glider and does not add any 
actions that increase the burden over the previous AD. 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-2014-0292 and directorate identifier 2014-CE-011-
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 118 products of U.S. registry. 
We also estimate that it would take about .5 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of the AD on U.S. 
operators to be $5,015, or $42.50 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 2 work-hours and require parts costing $244, for a cost of 
$414 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.

[[Page 63504]]

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.

(d) Subject

    Air Transport Association of America (ATA) Code 27: Flight 
Controls.

(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 plastic control 
cable pulleys developing cracks due to aging. We are issuing this AD 
to detect and correct plastic control cable pulleys in the rudder 
control unit, which could lead to breaking of the pulley and 
potentially jamming the rudder control unit, possibly resulting in 
loss of control of the glider.

(f) Actions and Compliance

    Comply with this AD within the compliance times specified in 
paragraphs (f)(1) through (f)(3) of this AD, unless already done.
    (1) For all Models G103C TWIN III ACRO and G 103 C Twin III SL 
gliders: Within 3 months after August 27, 2014 (the effective date 
retained from AD 2014-15-02, Amendment 39-17904 (79 FR 42658, July 
23, 2014)), inspect the rudder control unit for installation of 
plastic cable pulleys. If plastic cable pulleys are installed, 
before further flight, replace the plastic cable pulleys with 
aluminum cable pulleys following the actions and instructions of 
Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Service Bulletin SB-
G05 and Fiberglas-Technik Rudolf Lindner GmbH & Co. KG Instructions
