Sheet 1 of 1 \TM\20\20tm39e.doc //translated RBG// ASW 20, all production versions Technical Note No. 39 Alexander Schleicher GmbH & Co. Segelflugzeugbau D - 36163 Poppenhausen Subject: A) Amendment of the Maintenance Manual. B) Inspection Program To Increase The Service Life. Serial number applicability: ASW 20, all production versions, Data Sheet No. L-314. Compliance: A) Prior to the next annual C. of A. inspection, but before or on Dec. 31, 1998, at the latest. B) Prior to reaching a total service life of 3000 or 6000 flight hours respectively. Reason: Fatigue tests on CFRP wings and CFRP wing spars have shown that a service life ex- pectancy of 12000 hours can be reached for these components without problems. However, as this fatigue test program did not examine the entire aircraft made of CFRP and GRP, this service life of 12000 hours can be granted only if the long-term airworthi- ness of each individual aircraft is demonstrated in a special multi-stage inspection pro- gram (over and above the mandatory annual C of A inspections) for the purpose of in- creasing the service life. Action: The Maintenance Manual pages must be exchanged for new pages with the same page no., but with the revision entry & date „Issue 16.02.98 Jumtow / Revision: TN-No. 39“ and the additional new pages must be inserted. The accomplishment of the change to the Manual must be documented on Page "Index of Corrections" (Maintenance Manual) or Page "Amendments to the Manual" (Operations Manual) respectively. The instruc- tions and notes given in the amended and in the new manual pages must be regarded!
