Airworthiness Directives; PZL-Bielsko Model SZD-50-3 ``Puchacz'' 
Gliders

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) issued 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 a 
discrepancy between the design documentation and the Technical Service 
Manual. In 1981, a castellated nut with cotter pin was introduced to 
secure the rudder, replacing the self-locking nut through PZL-Bielsko 
Bulletin No. BE-06/50-3/81. This change has not been introduced to the 
Technical Service Manual and use of a self-locking nut, in accordance 
with the Manual, is still possible. We are issuing this AD to require 
actions that are intended to address the unsafe condition described in 
the MCAI.

DATES: This AD becomes effective January 8, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 8, 
2007.

ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility, U.S. 
Department of Transportation, 400 Seventh Street SW., Nassif Building, 
Room PL-401, Washington, DC.

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. The streamlined process will allow us to adopt 
MCAI safety requirements in a more efficient manner and will reduce 
safety risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This AD references the MCAI and related service information that we 
considered in forming the engineering basis to correct the unsafe 
condition. The AD contains text copied from the MCAI and for this 
reason might not follow our plain language principles.

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on September 27, 2006 
(71 FR 56416). That NPRM proposed to correct an unsafe condition for 
the specific products. The MCAI states that a discrepancy between the 
design documentation and the Technical Service Manual has been 
identified. In 1981, a castellated nut with cotter pin was introduced 
to secure the rudder, replacing the self-locking nut through PZL-
Bielsko Bulletin No BE-06/50-3/81. This change has not been introduced 
to the Technical Service Manual and use of a self-locking nut, in 
accordance with the Manual, is still possible. This was probably the 
reason of rudder disconnection during flight which occurred recently. 
If not corrected, loss of the nut could result and allow the rudder to 
slip out of its hinges, separate from the glider, and lead to loss of 
control. This AD requires you to inspect and, if necessary, replace the 
Rudder Attachment parts in accordance with the instruction contained in 
the Allstar PZL Glider Sp. z o.o. Mandatory Bulletin No. BE-058/SZD-50-
3/2006 ``PUCHACZ'', dated August 10, 2006. Concurrently, changes in the 
Technical Service Manual must be introduced in accordance with the 
referenced bulletin.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comments received.
    Jack Buster with the Modification and Replacement Parts Association 
(MARPA) provides comments to the MCAI AD process pertaining to how the 
FAA addresses publishing manufacturer service information as part of a 
proposed AD action. Mr. Buster states that the rule, as proposed, 
attempts to require compliance with a public law by reference to a 
private writing (as referenced in paragraph (e) of the proposed AD). 
Mr. Buster would like the FAA to incorporate by reference (IBR) the 
Allstar PZL Glider Sp. z o.o. Mandatory Bulletin.
    We agree with Mr. Buster. However, we do not IBR any document in a 
proposed AD action, instead we IBR the document in the final rule. 
Since we are issuing the proposal as a final rule AD action, Allstar 
PZL Glider Sp. z o.o. Mandatory Bulletin No. BE-058/SZD-50-3/2006 
``PUCHACZ'', dated August 10, 2006, is incorporated by reference.
    Mr. Buster requests that IBR documents be made available to the 
public by publication in the Federal Register or in the Docket 
Management System (DMS).
    We are currently reviewing issues surrounding the posting of 
service bulletins in the Department of Transportation's DMS as part of 
the AD docket. Once we have thoroughly examined all aspects of this 
issue and have made a final determination, we will consider whether our 
current practice needs to be revised.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
the AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable in a U.S. court of 
law. In making these changes, we do not intend to differ substantively 
from the information provided in the MCAI and related service 
information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the AD. These requirements, if 
any, take precedence over the actions copied from the MCAI.

[[Page 70301]]

Costs of Compliance

    We estimate that this AD will affect about 8 products of U.S. 
registry. We also estimate that it will take about 1.5 work-hours per 
product to comply with this AD. The average labor rate is $80 per work-
hour. Required parts will cost about $2 per product. Where the service 
information lists required parts costs that are covered under warranty, 
we have assumed that there will be no charge for these parts. As we do 
not control warranty coverage for affected parties, some parties may 
incur costs higher than estimated here. Based on these figures, we 
estimate the cost of this AD to the U.S. operators to be $976 or $122 
per product.

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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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 regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD Docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://dms.dot.gov; or in person at the Docket Management Facility between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains the NPRM, the regulatory evaluation, any comments 
received, and other information. The street address for the Docket 
Office (telephone (800) 647-5227) is in the ADDRESSES section. Comments 
will be available in the AD docket shortly after receipt.

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

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

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


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2006-24-09 PZL-Bielsko: Amendment 39-14838; Docket No. FAA-2006-
25810; Directorate Identifier 2006-CE-49-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective January 
8, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to PZL-Bielsko Model SZD-50-3 ``Puchacz'' 
gliders, all serial numbers, certificated in any category.

Reason

    (d) The mandatory continuing airworthiness information (MCAI) 
states that the aircraft manufacturer has identified a discrepancy 
between the design documentation and the Technical Service Manual. 
In 1981, a castellated nut with cotter pin was introduced to secure 
the rudder, replacing the self-locking nut, through PZL Bielsko 
Bulletin No. BE-06/50-3/81. This change has not been introduced to 
the Technical Service Manual and use of a self-locking nut, in 
accordance with the Manual, is still possible. This was probably the 
reason for rudder disconnection during flight which occurred 
recently. If not corrected, loss of the nut could result and allow 
the rudder to slip out of its hinges, separate from the glider, and 
lead to loss of control.

Actions and Compliance

    (e) Unless already done, do the following actions except as 
stated in paragraph (f) below: Within 30 days of January 3, 2007 
(the effective date of this AD) or before further flight, whichever 
occurs later, inspect and, if necessary, replace the Rudder 
Attachment parts in accordance with the instruction contained in 
Allstar PZL Glider Sp. z o.o. Mandatory Bulletin No. BE-058/SZD-50-
3/2006 ``PUCHACZ'', dated August 10, 2006. Concurrently, changes in 
the Technical Service Manual must be introduced in accordance with 
the referenced Bulletin.

FAA AD Differences

    (f) None.
