Airworthiness Directives; GROB-WERKE GMBH & CO KG Gliders

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) 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. This AD results from mandatory 
continuing airworthiness information (MCAI) issued 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 require actions to address the unsafe 
condition on these products.

DATES: This AD is effective August 27, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of August 27, 
2014.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to 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. The NPRM was published in the Federal Register 
on May 6, 2014 (79 FR 25753). The NPRM proposed to correct an unsafe 
condition for the specified products and was based on MCAI originated 
by an aviation authority of another country. The MCAI states:

    Control cable pulleys made from plastic (white or brown 
material) in the rudder control unit were reported to develop cracks 
due to aging. In one case, jamming of the rudder control unit was 
reported.
    This condition, if not detected and corrected, could cause cable 
pulleys to break, potentially jamming the rudder control unit and 
resulting in loss of control of the sailplane.
    To address this potential unsafe condition, Fiberglas-Technik 
issued Technische Mitteilung/Service Bulletin TM-G05/SB-G05 and 
Anweisung/Instructions A/I-G05 (one document) to provide 
instructions for the replacement of plastic cable pulleys with 
pulleys made from aluminium.
    For the reason described above, this AD requires identification 
and replacement of plastic cable pulleys in the rudder control unit.
    Plastic cable pulleys may also be installed in the cable 
circuits of pedal adjustment and/or tow hook actuation, their 
replacement is not required by this AD.

The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2014-0292-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 25753, May 6, 2014) 
or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting the AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (79 FR 25753, May 6, 2014) for correcting the unsafe condition; 
and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 25753, May 6, 2014).

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.

Regulatory Findings

    We 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 this AD:
    (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.

(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.
