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.

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.
