Airworthiness Directives; Alexander Schleicher Segelflugzeugbau Model ASK 21 Gliders

Publication summary

This action confirms the effective date of Airworthiness Directive (AD) 95-11-15 R1, which applies to Alexander Schleicher Segelflugzeugbau (Alexander Schleicher) Model ASK 21 gliders. AD 95-11- 15 R1 requires replacing the parallel rocker with a part of improved design and incorporating flight manual revisions, but only for those gliders with the automatic elevator connection incorporated. AD 95-11- 15 was the result of two incidents of the parallel rocker breaking at the elevator connection on the affected gliders. Since that time, the FAA has determined that the AD should only affect those Model ASK 21 gliders equipped with the automatic elevator connection. The actions specified in this AD are intended to continue to prevent possible loss of elevator control that could result from a broken parallel rocker.

Airworthiness Directives; Alexander Schleicher Segelflugzeugbau 
Model ASK 21 Gliders

AGENCY: Federal Aviation Administration, DOT.

ACTION: Direct final rule; confirmation of effective date.

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

SUMMARY: This action confirms the effective date of Airworthiness 
Directive (AD) 95-11-15 R1, which applies to Alexander Schleicher 
Segelflugzeugbau (Alexander Schleicher) Model ASK 21 gliders. AD 95-11-
15 R1 requires replacing the parallel rocker with a part of improved 
design and incorporating flight manual revisions, but only for those 
gliders with the automatic elevator connection incorporated. AD 95-11-
15 was the result of two incidents of the parallel rocker breaking at 
the elevator connection on the affected gliders. Since that time, the 
FAA has determined that the AD should only affect those Model ASK 21 
gliders equipped with the automatic elevator connection. The actions 
specified in this AD are intended to continue to prevent possible loss 
of elevator control that could result from a broken parallel rocker.

EFFECTIVE DATE: July 25, 1999.

FOR FURTHER INFORMATION CONTACT: Mr. Mike Kiesov, Aerospace Engineer, 
FAA, Small Airplane Directorate, 1201 Walnut, suite 900, Kansas City, 
Missouri 64106; telephone: (816) 426-6932; facsimile: (816) 426-2169.

SUPPLEMENTARY INFORMATION: The FAA published this direct final rule 
with request for comments in the Federal Register on April 26, 1999 (64 
FR 20142). The FAA uses the direct final rulemaking procedure for a 
non-controversial rule where the FAA anticipates that there will be no 
adverse public comment. This direct final rule advised the public that 
no adverse comments were anticipated, and that unless a written adverse 
comment, or a written notice of intent to submit such an adverse 
comment, was received within the comment period, the regulation would 
become effective on July 25, 1999. No adverse comments were received, 
and thus this notice confirms that this final rule will become 
effective on that date.

    Issued in Kansas City, Missouri, on June 11, 1999.
Marvin R. Nuss,
Acting Manager, Small Airplane Directorate, Aircraft Certification 
Service.
