Airworthiness Directives; Barry Aviation, LLC Model PZL-Krosno 
KR-03A ``Peregrine'' (Puchatek) Sailplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to certain Barry Aviation, LLC

[[Page 53476]]

Model PZL-Krosno KR-03A ``Peregrine'' (Puchatek) sailplanes. This AD 
requires you to inspect to ensure that the correct horizontal 
stabilizer attachment fittings are installed, install the correct 
fittings if necessary, and incorporate a ``NO LIFT'' placard to the 
vertical stabilizer. This AD is the result of reports of cracks in the 
horizontal stabilizer attachment fittings on the affected sailplanes. 
Analysis of these incidents reveals that incorrect fittings were 
installed. The actions specified by this AD are intended to prevent 
such cracks in the horizontal stabilizer attachment fittings, which 
could result in the horizontal stabilizer separating from the sailplane 
with consequent loss of control of the sailplane.

DATES: This AD becomes effective on August 30, 2002.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulation as of August 
30, 2002.
    The Federal Aviation Administration (FAA) must receive any comments 
on this rule on or before September 27, 2002.

ADDRESSES: Submit comments to FAA, Central Region, Office of the 
Regional Counsel, Attention: Rules Docket No. 2002-CE-30-AD, 901

SUPPLEMENTARY INFORMATION:

Discussion

What Events Have Caused This AD?

    The FAA has received several reports of cracked horizontal 
stabilizer attachment fittings on certain Barry Aviation, LLC Model 
PZL-Krosno KR-03A ``Peregrine'' (Puchatek) sailplanes. Polish 
manufacturer PZL-Krosno previously held the type certificate for these 
sailplanes.
    Metallurgical analysis of one fitting indicated fatigue as the 
cause of the incidents. In 1993, PZL-Krosno issued a design note to 
specify the installation of horizontal stabilizer attachment fittings 
that had a flange of 3 millimeters (mm) thick instead of 1.5 mm thick.
    All reports of cracked horizontal stabilizer attachment fittings 
incorporated horizontal stabilizer attachment fittings with a flange of 
1.5 mm thick.

What Are the Consequences if the Condition Is Not Corrected?

    Cracked horizontal stabilizer attachment fittings, if not 
prevented, could result in the horizontal stabilizer separating from 
the sailplane with consequent loss of control of the sailplane.

Is There Service Information That Applies to This Subject?

    The following service information relates to this subject:

--Barry Aviation ``Krosno KR-03A Glider'' Service Bulletin No. 1-02, 
dated June 10, 2002: This document includes procedures for inspecting 
the stabilizer attachment fittings to ensure that the increased 
thickness flange fittings are installed and specifies replacement if 
necessary; and
--WSK ``PZL-Krosno'' Service Bulletin No. BE-29/KR-03A/93, dated 
November 16, 1993: This document includes procedures for replacing the 
stabilizer attachment fittings with fittings that have increased 
thickness flanges and incorporating a ``NO LIFT'' placard to the 
vertical stabilizer.

The FAA's Determination and an Explanation of the Provisions of This AD

What Has FAA Decided?

    The FAA has reviewed all available information, including the 
service information referenced above; and determined that:

--The unsafe condition referenced in this document exists or could 
develop on other Barry Aviation, LLC Model PZL-Krosno KR-03A 
``Peregrine'' (Puchatek) sailplanes of the same type design;
--The actions specified in the previously-referenced service 
information (as specified in this AD) should be accomplished on the 
affected sailplanes; and
--AD action should be taken in order to correct this unsafe condition.

What Does This AD Require?

    This AD requires you to inspect to ensure that the correct 
horizontal stabilizer attachment fittings are installed, install the 
correct fittings if necessary, and incorporate a ``NO LIFT'' placard to 
the vertical stabilizer.

Will I Have the Opportunity To Comment Prior to the Issuance of the 
Rule?

    Because the unsafe condition described in this document could 
result in the horizontal stabilizer separating from the sailplane with 
consequent loss of control of the sailplane, we find that notice and 
opportunity for public prior comment are impracticable. Therefore, good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

How Do I Comment on This AD?

    Although this action is in the form of a final rule and was not 
preceded by notice and opportunity for public comment, FAA invites your 
comments on the rule. You may submit whatever written data, views, or 
arguments you choose. You need to include the rule's docket number and 
submit your comments to the address specified under the caption 
ADDRESSES. We will consider all comments received on or before the 
closing date specified above. We may amend this rule in light of 
comments received. Factual information that supports your ideas and 
suggestions is extremely helpful in evaluating the effectiveness of the 
AD action and determining whether we need to take additional rulemaking 
action.

Are There Any Specific Portions of the AD I Should Pay Attention to?

    We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify the rule. You may view all comments we receive 
before and after the closing date of the rule in the Rules Docket. We 
will file a report in the Rules Docket that summarizes each FAA contact 
with the public that concerns the substantive parts of this AD.

[[Page 53477]]

How Can I Be Sure FAA Receives My Comment?

    If you want us to acknowledge the receipt of your written comments, 
you must include a self-addressed, stamped postcard. On the postcard, 
write ``Comments to Docket No. 2002-CE-30-AD.'' We will date stamp and 
mail the postcard back to you.

Regulatory Impact

Does This AD Impact Various Entities?

    These regulations 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. Therefore, FAA has determined that this 
final rule does not have federalism implications under Executive Order 
13132.

Does This AD Involve a Significant Rule or Regulatory Action?

    We have determined that this regulation is an emergency regulation 
that must be issued immediately to correct an unsafe condition in 
aircraft, and is not a significant regulatory action under Executive 
Order 12866. It has been determined further that this action involves 
an emergency regulation under DOT Regulatory Policies and Procedures 
(44 FR 11034, February 26, 1979). If it is determined that this 
emergency regulation otherwise would be significant under DOT 
Regulatory Policies and Procedures, a final regulatory evaluation will 
be prepared and placed in the Rules Docket (otherwise, an evaluation is 
not required). A copy of it, if filed, may be obtained from the Rules 
Docket.
