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

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2004-11-10 for 
Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa ``PZL-Bielsko'' 
Model SZD-50-3 ``Puchacz'' sailplanes. 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 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 AD to require actions to address the 
unsafe condition on these products.

DATES: This AD is effective July 22, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of July 22, 
2014.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to add an AD that would apply to Przedsiebiorstwo 
Doswiadczalno-Produkcyjne Model SZD-50-3 ``Puchacz'' airplanes. The 
NPRM was published in the Federal Register on March 25, 2014 (79 FR 
16248), and proposed to supersede AD 2004-11-10, Amendment 39-13656 (69 
FR 31872, June 8, 2004).
    The NPRM proposed to correct an unsafe condition for the specified 
products and was based on mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country. The MCAI states that:

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.

The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2014-0180-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM 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:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 16248, March 25, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 16248, March 25, 2014).

Costs of Compliance

    We estimate that this AD will affect 5 products of U.S. registry. 
We also estimate that it would take about 5 work-hours for the annual 
inspection of sailplanes equipped with the old version torque tube; 1 
work-hour for the annual inspection of sailplanes equipped with the new 
version torque tube; and 5 work-hours for the 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.

[[Page 34407]]

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.

2. The FAA amends Sec.  39.13 by removing Amendment AD 2004-11-10, 
Amendment 39-13656 (69 FR 31872, June 8, 2004) and adding the following 
new AD:

2014-12-08 Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa 
``PZL-Bielsko'': Amendment 39-17869; Docket No. FAA-2014-0180; 
Directorate Identifier 2014-CE-004-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective July 22, 
2014.

(b) Affected ADs

    This AD supersedes AD 2004-11-10, Amendment 39-13656 (69 FR 
31872; June 8, 2004).

(c) Applicability

    This AD applies to Przedsiebiorstwo Doswiadczalno-Produkcyjne 
Szybownictwa ``PZL-Bielsko'' Model SZD-50-3 ``Puchacz'' sailplanes,

This packet is not an airworthiness determination and not legal or maintenance advice. AircraftDirectives reproduces official records and condenses their wording for easier reading. It does not decide, certify or imply whether any aircraft, engine, appliance or part is airworthy, compliant, affected by this directive, or eligible for return to service. No inspection, approval, or determination of any kind is performed or implied by this document.

Section 1 is a reading aid, not the rule. It is our own plain-language condensation, written to help a reader find the relevant directive quickly. It is NOT a substitute for the regulation, it may omit conditions, exceptions, compliance times, alternative methods of compliance (AMOCs) and applicability limits, and it has no legal force whatsoever. Only the official text governs. Where Section 1 and Section 2 differ in any respect, Section 2 - and the official source it was retrieved from - controls absolutely.

Responsibility remains with the owner/operator. Under 14 CFR §91.403 and §91.417 the owner or operator is responsible for maintaining airworthiness and for required records; under §39.7 no person may operate a product to which an airworthiness directive applies except in accordance with that directive. Determining applicability to a specific serial number and configuration, and performing or supervising any required action, is the responsibility of the owner/operator and appropriately certificated personnel.

Accuracy and currency. Section 2 was retrieved at the time stamped above and is reproduced without edit; Federal Register material is a work of the United States Government. Directives are amended, corrected and superseded over time, and this sheet is a snapshot, not a live record - it does not update after printing. Re-check the official sources before acting on it. This packet is provided without warranty of any kind, express or implied, including fitness for a particular purpose. We do not sell parts and have no commercial interest in any action a directive may require.
