# 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. 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 detachment of the rudder cable fitting block from the fuselage. We are issuing this proposed AD to require actions to address the unsafe condition on these products.

## Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2015-0046, dated March 16, 2015 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

An occurrence was reported involving a SZD-50-3 “Puchacz” sailplane, where a rudder cable fitting block, located in the forward part of the fuselage, detached after application of a high load on the steering pedal during spin recovery operation. Subsequent investigations determined that the failure was either caused by a manufacturing deficiency or originated by a crack.

This condition, if not detected and corrected, could lead to further cases of rudder cable fitting block detachment, resulting in reduced control of the sailplane.

To address this unsafe condition, Allstar PZL issued Service Bulletin (SB) No. BE-063/SZD-50-3/2014, to provide inspection and reinforcement instructions.

For the reasons described above, this AD requires accomplishment of a one-time inspection of both (right hand (RH) and left hand (LH)) rudder cable fitting blocks to verify proper attachment to the fuselage shell and, depending on finding(s), a repair. This AD also requires reinforcement of the affected structural area.

                    You may examine the MCAI on the Internet at                     *http://www.regulations.gov*                     by searching for and locating Docket No. FAA-2015-0951.                

## Related Service Information Under 1 CFR part 51

                    Allstar PZL Glider has issued Mandatory Service Bulletin No.  BE-063/SZD-50-3/2014 “Puchacz”, dated December 14, 2014. The service bulletin describes procedures for inspecting the area around the left-hand and right-hand rudder cable fitting blocks for cracks and detachment and making all necessary repairs. This service information is reasonably available because the interested parties have access to it through their normal course                           ( print page 21192)                        of business or by the means identified in the                     **ADDRESSES**                     section of this NPRM.                

## 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 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 1 work-hour per product to comply with the inspection requirement of this proposed AD. The average labor rate is $85 per work-hour.

Based on these figures, we estimate the cost of the proposed inspection requirement of this proposed AD on U.S. operators to be $425, or $85 per product.

In addition, we estimate that it would take about 2 work-hours per product to comply with the modification requirement of this proposed AD and would require parts costing $100.

## 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.

## The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

# PART 39—AIRWORTHINESS DIRECTIVES

1. The authority citation for part 39 continues to read as follows: 

Authority:49 U.S.C. 106(g), 40113, 44701.

§ 39.13 

2. The FAA amends § 39.13 by adding the following new AD: 

**Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa “PZL-Bielsko”:**                         Docket No. FAA-2015-0951; Directorate Identifier 2015-CE-007-AD.                    

## (a) Comments Due Date

We must receive comments by June 1, 2015.

## (b) Affected ADs

None.
