14 CFR Part 39
[Docket No. 2001-CE-05-AD; Amendment 39-12145; AD 2001-05-08]
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.
You may get service information referenced in this AD from Korff + Co. KG, Luftfahrttechnischer Betrieb, LBA II-A 189, Dieselstrasse 5, D- 63128, Dietzenbach, Germany; telephone: (49) 6074/4006; facsimile: (49) 6074/4033. You may read this information at FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2001-CE-05-AD, 901 Locust, Room 506, Kansas City, Missouri 64106; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC.
FOR FURTHER INFORMATION 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.
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.
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.
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.
