Airworthiness Directives; VALENTIN GmbH Model 17E Sailplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to all VALENTIN GmbH (Valentin) Model 17E sailplanes. This AD 
requires you to inspect for, and correct, cracked or improperly 
installed central wing bolts; install a stronger central bolt if not 
already installed; and inspect for, and replace, problem telescopic 
rods. This AD is the result of mandatory continuing airworthiness 
information (MCAI) issued by the airworthiness authority for Germany. 
The actions specified by this AD are intended to correct improperly 
installed or cracked central bolts and damaged, deformed, or loose 
telescopic rods. This condition, if not corrected, could cause the wing 
to separate from the sailplane, which could cause result in control of 
the sailplane.

DATES: This AD becomes effective on April 13, 2001.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the regulation as of April 
13, 2001.
    The Federal Aviation Administration (FAA) must receive any comments 
on this rule by April 13, 2001.

ADDRESSES: Send three copies of comments to FAA, Central Region, Office 
of the Regional Counsel, Attention: Rules Docket No. 2001-CE-05-AD, 901 
Locust, Room 506, Kansas City, Missouri 64106.

SUPPLEMENTARY INFORMATION:

Discussion

    What events have caused this AD? The Luftfahrt-Bundesamt (LBA), 
which is the airworthiness authority for Germany, recently notified FAA 
that an unsafe condition might exist on certain Valentin Model 17E 
sailplanes. The LBA reports:

--Occurrences of the manufacturer installing central bolts in the wrong 
direction;
--Cracks found in nine central bolts during inspections; and
--A fatal accident that could possibly be attributed to a weak central 
bolt breaking.

    What are the consequences if the condition is not corrected? This 
condition, if not corrected, could result in the wing separating from 
the sailplane, which could cause loss of control of the sailplane.
    Is there service information that applies to this subject? Valentin 
has issued Service Bulletin KOCO 05/818, issue 2, and Korff Work 
Instructions AW-KOCO-05/818, issue 2, both dated 16 January 2001. The 
service bulletin and work instructions include procedures for:

--Inspecting the central bolt for correct installation;
--Inspecting the central bolt for cracks;
--Installing a stronger central bolt; and
--Inspecting the telescopic rods and locking mechanisms for damage, 
removing any damaged parts, and repairing or replacing any damaged 
parts.

    What action did LBA take? The LBA classified this service bulletin 
as mandatory and issued German AD 2000-392, dated December 15, 2000, to 
ensure the continued airworthiness of these sailplanes in Germany.
    Was this in accordance with the bilateral airworthiness agreement? 
These sailplane models are manufactured in Germany 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.
    In carrying out this bilateral airworthiness agreement, the LBA has 
kept FAA informed of the situation described above.

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

    What has FAA decided? The FAA has examined the findings of the LBA; 
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 Valentin Model 17E 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 do the actions 
previously specified in accordance with Korff + Co. KG Service Bulletin 
KOCO 05/818, issue 2, and Korff Work Instructions AW-KOCO-05/818, issue 
2, both dated 16 January 2001.
    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 structural failure with possible loss of control of the 
sailplane, FAA finds that notice and opportunity for public comment 
before issuance are impractical. 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, we invite your comments on the rule. You may send whatever 
written data, views, or arguments you choose. You need to include the 
rule's docket number and send three copies of your comments to the 
address specified under the caption ADDRESSES. We will consider all 
comments received by the closing date specified above. We may change 
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? The FAA specifically invites comments on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
require a change to the rule. You may look at all comments we receive. 
We will file a report in the Rules Docket that summarizes each FAA 
contact with the public that concerns the substantive parts of this 
rule.
    We are reviewing the writing style we currently use in regulatory 
documents, in response to the Presidential memorandum of June 1, 1998. 
That memorandum requires federal agencies to communicate more clearly 
with the public. We are interested in your comments on whether the 
style of this document is clear, and any other suggestions you might 
have to improve the clarity of FAA communications that affect you. You 
can get more information about the Presidential memorandum and the 
plain language initiative at http://www.plainlanguage.gov.
    How can I be sure FAA receives my comment? If you want us to 
acknowledge the receipt of your comments, you must include a self-
addressed, stamped postcard. On the postcard, write ``Comments to 
Docket No. 2001-CE-05-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? The 
FAA has 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.

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

    (e) Can I comply with this AD in any other way? You may use an 
alternative method of compliance or adjust the compliance time if:
    (1) Your alternative method of compliance provides an equivalent 
level of safety; and
    (2) The Manager, Small Airplane Directorate, approves your 
alternative. Send your request through an FAA Principal Maintenance 
Inspector, who may add comments and then send it to the Manager, 
Small Airplane Directorate.

    Note 1: This AD applies to each sailplane identified in 
paragraph (a) of this AD, regardless of whether it has been 
modified, altered, or repaired in the area subject to the 
requirements of this AD. For sailplanes that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (e) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and, if you have not eliminated the unsafe 
condition, specific actions you propose to address it.

    (f) Where can I get information about any already-approved 
alternative methods of compliance? Contact Mike Kiesov, Aerospace 
Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, 
Kansas City, Missouri 64106; telephone: (816) 329-4144; facsimile: 
(816) 329-4090.
    (g) What if I need to fly the sailplane to another location to 
comply with this AD? The FAA can issue a special flight permit under 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate your sailplane to a location where 
you can accomplish the requirements of this AD.
    (h) Are any service bulletins incorporated into this AD by 
reference? Actions required by this AD must be done following Korff 
+ Co. KG Service Bulletin-KOCO 05/818, issue 2, and Korff Work 
Instructions AW-KOCO 05/818, issue 2, both dated January 16, 2001.
