Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to adopt a new airworthiness directive (AD) for certain PZL-Swidnik S.A. (PZL-Swidnik) Models PW-5 “Smyk” and PW-6U gliders. This proposed AD would require you to inspect for the minimum dimension of the left side aileron, right side aileron, and airbrake push-rod ends for certain Model PW-5 “Smyk” gliders; inspect for the minimum dimension of the aileron, airbrake, and elevator control push-rod ends for certain Model PW-6U gliders; and replace any push-rod end that does not meet the minimum dimension. This proposed AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Poland. We are issuing this proposed AD to detect and replace any push-rod end that does not meet the minimum dimension, which could result in failure of the control system. This failure could lead to loss of control of the glider.

DATES:

We must receive any comments on this proposed AD by May 27, 2005.

Discussion

What events have caused this proposed AD? The General Inspectorate of Civil Aviation (GICA), which is the airworthiness authority for Poland, recently notified FAA that an unsafe condition may exist on certain PZL-Swidnik S.A. (PZL-Swidnik) gliders. The GICA reports that an owner of a Model PW-6U glider found the dimension of the push-rod end to not meet the minimum dimension of 0.165 inches (in.) or 4.2 millimeter (mm). Further, the GICA reports that the manufacturer has identified a production run of these parts that do not meet the minimum dimension of the push-rod end. Similar push-rod ends, where applicable, are used to link the ailerons, airbrakes, and elevator control systems in the Models PW-5 “Smyk” and PW-6U gliders.

What is the potential impact if FAA took no action? Any push-rod end that does not meet the minimum dimension could result in failure of the control system. This failure could lead to loss of control of the glider.

Is there service information that applies to this subject? PZL-Swidnik has issued:

—Mandatory Bulletin Number BO-17-03-18, dated December 22, 2003, for the Model PW-5 “Smyk” gliders.

—Mandatory Bulletin Number BO-78-03-06, dated December 22, 2003, for the Model PW-6U gliders.

What are the provisions of this service information? The service information includes procedures for:

—Inspecting for the minimum dimension of the left side aileron, right side aileron, and airbrake push-rod ends for the Model PW-5 “Smyk” gliders;

—Inspecting for the minimum dimension of the aileron, airbrake, and elevator control push-rod ends for the Model PW-6U gliders; and

—Replacing any push-rod end that does not meet the minimum dimension.

What action did the GICA take? The GICA classified this service bulletin as mandatory and issued Polish AD Numbers SP-0085-2003-A, dated December 22, 2003, and SP-0086-2003, dated December 22, 2003, to ensure the continued airworthiness of these gliders in Poland.

Did the GICA inform the United States under the bilateral airworthiness agreement? These PZL-Swidnik Models PW-5 “Smyk” and PW-6U gliders are manufactured in Poland and are type-certificated for operation in the United States under the provisions of § 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement.

Under this bilateral airworthiness agreement, the GICA has kept us informed of the situation described above.

FAA's Determination and Requirements of This Proposed AD

What has FAA decided? We have examined the GICA's findings, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States.

Since the unsafe condition described previously is likely to exist or develop on other PZL-Swidnik Models PW-5 “Smyk” and PW-6U gliders of the same type design that are registered in the United States, we are proposing AD action to detect and replace any push-rod end that does not meet the minimum dimension, which could result in failure of the control system. This failure could lead to loss of control of the glider.

What would this proposed AD require? This proposed AD would require you to incorporate the actions in the previously-referenced service bulletin.

How does the revision to 14 CFR part 39 affect this proposed AD? On July 10, 2002, we published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs FAA's AD system. This regulation now includes material that relates to altered products, special flight permits, and alternative methods of compliance. This material previously was included in each individual AD. Since this material is included in 14 CFR part 39, we will not include it in future AD actions.

Costs of Compliance

How many gliders would this proposed AD impact? We estimate that this proposed AD affects 67 gliders in the U.S. registry.

What would be the cost impact of this proposed AD on owners/operators of the affected gliders? We estimate the following costs to do this proposed inspection of the push-rod ends:

Labor costParts costTotal cost per gliderTotal cost on U.S. operators
1 work hour × $65 = $65Not Applicable$6567 × $65 = $4,355

We estimate the following costs to do any necessary push-rod end replacements that would be required based on the results of this proposed inspection. We have no way of determining the number of gliders that may need this replacement:

Labor cost per push-rod endParts costTotal cost per push-rod end per glider
1 work hour × $65 = $65Not Applicable$65
Start Printed Page 21693

The manufacturer has stated that the costs for any required parts and transportation will be covered under the manufacturer's warranty.

Authority for This Rulemaking

What authority does FAA have for issuing this rulemaking action? 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 AD.

Regulatory Findings

Would this proposed AD impact various entities? We have 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.

Would this proposed AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this proposed 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); and

3. 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.

We prepared a summary of the costs to comply with this proposed AD (and other information as included in the Regulatory Evaluation) and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include “AD Docket FAA-2005-20802; Directorate Identifier 2005-CE-18-AD” in your request.
