## Abstract

This amendment adopts a new airworthiness directive (AD) that applies to all Ursula Hanle (Hanle) Model H101 ``Salto'' sailplanes. This AD requires replacing the airbrake lever with one of improved design. 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 prevent the airbrake from deploying during high g maneuvers, which could result in an overstressing effect on the airframe with consequent reduced sailplane control.
