AD 95-13-09 60 FR 33685

This amendment adopts a new airworthiness directive (AD) that applies to certain Grob Luft Und Raumfahrt (Grob) Models G102 Astir CS, Club Astir IIb, Twin Astir, Speed Astir, Standard Astir II, and Speed Astir IIb sailplanes. This action requires inspecting all elevator and rudder hinges for damage (delamination, cracks, corrosion, or buckling), and repairing any damaged parts. Several occurrences of inner elevator hinges separating during flight operation prompted this AD action. The actions specified by this AD are intended to prevent these hinges from separating, which could result in sailplane flutter and eventual loss of control of the sailplane.
