Airworthiness Directives; Diamond Aircraft Industries GmbH Models HK 36 R “Super Dimona”, HK 36 TC, HK 36 TS, HK 36 TTC, HK 36 TTC-ECO, HK 36 TTC-ECO (Restricted Category), and HK 36 TTS Sailplanes

This amendment clarifies information contained in Airworthiness Directive (AD) 2002-15-01, which currently requires you to inspect the long aileron push rods in both wings for damage and modify the push rods on all Diamond Aircraft Industries GmbH (Diamond) Models H-36 "Dimona", HK 36 R "Super Dimona", HK 36 TC, HK 36 TS, HK 36 TTC, HK 36 TTC-ECO, HK 36 TTC-ECO (Restricted Category), and HK 36 TTS sailplanes. The Model H-36 "Dimona" sailplane has a different flight control system than the rest of the affected sailplanes. This particular flight control system makes it impossible for the Model H-36 "Dimona" sailplanes to be in compliance with AD 2002-15-01. This document deletes these sailplanes from the AD applicability. The actions specified by this AD are intended to detect and correct damage in the long aileron push control rods, which could result in failure of the aileron push rods and decreased control. Such failure could lead to aeroelastic flutter.
