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.

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 Start Printed Page 16249Design 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.
