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 E:\FR\FM\10AUP1.SGM 10AUP1 46440 Federal Register / Vol. 70, No. 153 / Wednesday, August 10, 2005 / Proposed Rules the 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 cost Total cost per glider Total 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 cost Parts cost Total 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 VerDate jul<14>2003 15:14 Aug 09, 2005 Jkt 205001 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 PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 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; E:\FR\FM\10AUP1.SGM 10AUP1 Federal Register / Vol. 70, No. 153 / Wednesday, August 10, 2005 / Proposed Rules Directorate Identifier 2005–CE–36–AD’’ in your request. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the Federal Aviation Administration 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 [Amended] 2.

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

[[Page 46440]]

the 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:

------------------------------------------------------------------------
                                       Total cost per     Total cost on
             Labor cost                    glider        U.S. operators
------------------------------------------------------------------------
1 workhour x $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:

------------------------------------------------------------------------
                                                         Total cost per
             Labor cost                  Parts cost          glider
------------------------------------------------------------------------
1 workhour x $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;
