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 all Przedsiebiorstwo Doswiadczalno-Produkcyjne Szybownictwa “PZL-Bielsko” Model SZD-50-3 “Puchacz” gliders. This proposed AD would require you to perform a visual inspection of the turnbuckle link for cracks or wear and replace if cracks or wear is found. This proposed action would only apply to those gliders where the turnbuckle is directly connected to the pedal. 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 correct cracks in the turnbuckle link, which could result in failure of the rudder cable. This failure could lead to loss of control of the glider.

DATES:

We must receive any comments on this proposed AD by September 29, 2005.

Discussion

What events have caused this proposed AD? The Civil Aviation Office, which is the airworthiness authority for Poland, recently notified FAA that an unsafe condition may exist on all Przedsiebiorstwo Doswiadczalno—Produkcyjne Szybownictwa “PZL-Bielsko” Model SZD-50-3 “Puchacz” gliders. The Civil Aviation Office reports a broken turnbuckle on a glider performing rudder operations in flight. Specifically, material fatigue caused the end of the turnbuckle that connects the rudder cable with rear seat, right-side pedal to break. Occupants, because of glider design, may have stepped on the rudder cable while entering or exiting Start Printed Page 46440the glider, putting stress on the turnbuckle link. This may have contributed to the material fatigue.

What is the potential impact if FAA took no action? Cracks or wear in the turnbuckle link could result in failure of the rudder cable. This failure could lead to loss of control of the glider.

Is there service information that applies to this subject? PZL-Bielsko has issued Mandatory Bulletin No. BE-054/SZD-50-3/2003 “Puchacz,” as approved in the Republic of Poland Civil Aviation Office AD No. SP-0012-2004-A, dated February 5, 2004.

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

—Visually inspecting the turnbuckle end for excessive wear and cracks; and

—Replacing the turnbuckle end if wear or cracks are found.

What action did the Civil Aviation Office take? The Civil Aviation Office classified this service bulletin as mandatory and issued Polish AD Number SP-0012-2004-A, dated February 5, 2004, to ensure the continued airworthiness of these gliders in Poland.

Did the Civil Aviation Office inform the United States under the bilateral airworthiness agreement? These PZL-Bielsko Model SZD-50-3 “Puchacz” gliders are manufactured in Poland and are type-certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement.

Under this bilateral airworthiness agreement, the Civil Aviation Office 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 Civil Aviation Office'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-Bielsko Model SZD-50-3 “Puchacz” gliders of the same type design that are registered in the United States, we are proposing AD action to detect and correct cracks in the turnbuckle link that could result in failure of the rudder cable. 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 8 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:

Labor costTotal cost per gliderTotal cost on U.S. operators
1 workhour × $65 = $65$65$520

We estimate the following costs to do any necessary 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 repair/replacement:

Labor costParts costTotal cost per glider
1 workhour × $65 = $65$20$85

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-2005-21836; Start Printed Page 46441Directorate Identifier 2005-CE-36-AD” in your request.
