Airworthiness Directive · Amendment 39-13887 · Schempp-Hirth Flugzeugbau GmbH Model Duo-Discus Gliders
Schempp-Hirth Flugzeugbau GmbH Model Duo-Discus Gliders
This AD affects Model Duo-Discus gliders, serial numbers 1 through 164, that are certificated in any category
The FAA is adopting a new airworthiness directive (AD) for certain Schempp-Hirth (SCHEMPP-HIRTH) Flugzeugbau GmbH Model Duo-Discus gliders. This AD requires you to do a one-time inspection of the bonding of the spar cap and spar web and repair any defective bonding of the spar cap and spar web. 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 detect and correct failure of the bonding of the spar cap and spar web, which, if not detected and corrected, could result in an in-flight wing failure.
To address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Inspect the bonding between the spar cap and the spar web for defects | Within the next 10 hours time-in-service (TIS) after December 30, 2004 (the effective date of this AD) | Follow SCHEMPP-HIRTH Flugzeugbau GmbH. Kircheim/Teck Technical Note No. 396-9, dated January 30, 2004; and SCHEMPP-HIRTH Flugzeugbau GmbH. Kircheim/Teck Appendix to Technical Note No. 396-9, dated January 30, 2004. |
| (2) Repair any defect in the bonding between the spar cap and the spar web | Prior to further flight after the inspection required by paragraph (e)(1) of this AD | Follow SCHEMPP-HIRTH Flugzeugbau GmbH. Kircheim/Teck Technical Note No. 396-9, dated January 30, 2004; SCHEMPP-HIRTH Flugzeugbau GmbH. Kircheim/Teck Appendix to Technical Note No. 396-9, dated January 30, 2004; and the applicable maintenance manual. |
