Airworthiness Directives; Przedsiebiorstwo Doswiadczalno-
Produkcyjne Szybownictwa ``PZL-Bielsko'' Model SZD-50-3 ``Puchacz'' 
Sailplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa ``PZL-Bielsko'' 
Model SZD-50-3 ``Puchacz'' sailplanes that would supersede AD 2004-11-
10. This proposed AD results from 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 fatigue damage of 
the welded joint between the airbrake torque tube and the airbrake 
control system lever located inside the fuselage. We are issuing this 
proposed AD to require actions to address the unsafe condition on these 
products.

DATES: We must receive comments on this proposed AD by May 9, 2014.

Discussion

    On May 27, 2004, we issued AD 2004-11-10, Amendment 39-13656 (69 FR 
31872; June 8, 2004). That AD required actions intended to address an 
unsafe condition on Przedsiebiorstwo Doswiadczalno-Produkcyjne 
Szybownictwa ``PZL-Bielsko'' Model SZD-50-3 ``Puchacz'' sailplanes.
    Since we issued AD 2004-11-10 (69 FR 31872; June 8, 2004), service 
information has been introduced that identifies new inspection and 
replacement requirements on the airbrake torque tube and the airbrake 
control system lever.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No.: 2014-0015, dated January 14, 2014 (referred to after this as 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Several occurrences of airbrake torque tube failure were 
reported on SZD-50-3 ``Puchacz'' sailplanes. In all cases, as a 
result of disruption of the welded joint between torque tube and the 
lever, the broken torque tube detached from the lever located in the 
fuselage. The result of subsequent investigations identified fatigue 
damage, as a consequence of periodical striking load exceeding the 
established maximum value, to be a possible failure cause. 
Additionally, corrosion damage was identified at internal surface of 
the opened tube.
    This condition, if not detected and corrected, would inhibit the 
function of the airbrake, possibly resulting in reduced control of 
the sailplane.
    Prompted by these findings, Allstar PZL issued Service Bulletin 
(SB) No. BE-052/SZD-50-3/2003 to provide inspection instructions. 
CAO of Poland issued AD SP-0052-2003-A to require a one-time 
inspection of the airbrake torque tube in the area of welded joint 
in accordance with that SB.
    Since that AD was issued, Allstar PZL issued SB No. BE-062/SZD-
50-3/2013 to introduce repetitive inspections and accomplishment 
instructions for reinforced torque tube inspections.
    For the reasons described above, this AD supersedes CAO of 
Poland AD SP-0052-2003-A and requires repetitive inspections of the 
airbrake torque tube and, depending on findings, replacement with a 
serviceable part.

You may examine the MCAI on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2014-0180.

Relevant Service Information

    Allstar PZL Glider has issued Allstar PZL Glider Sp. Z o.o. 
Mandatory Service Bulletin No. BE-062/SZD-50-3/2013 ``Puchacz'', dated 
September 16, 2013. 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

[[Page 16249]]

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.

Costs of Compliance

    We estimate that this proposed AD will affect 5 products of U.S. 
registry. We also estimate that it would take about 5 hours for the 
proposed annual inspection of sailplanes equipped with the old version 
torque tube; 1 hour for the proposed annual inspection of sailplanes 
equipped with the new version torque tube; and 5 hours for the proposed 
1,000-hour annual inspection of sailplanes equipped with the new 
version torque tube. The average labor rate is $85 per work-hour.
    In addition, we estimate that any necessary follow-on actions would 
take about 5 work-hours and require parts costing $875, for a cost of 
$1,300 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.
