## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to HB Flugtechnik GmbH (Flugtechnik) Model HB-23/ 2400 sailplanes. The proposed action would require inspecting (one time) the elevator control system for incorrect rigging and repetitively inspecting the threaded adjustable extension joints in the push rod to control lever connection for cracks, and, if cracked, replacing the threaded adjustable joints at both ends of the push rod. Cracking of the threaded adjustable extension joints and incorrect rigging of the elevator control system prompted the proposed action. The actions specified by the proposed AD are intended to prevent failure of the elevator control system, which, if not detected and corrected, could result in possible loss of elevator control and loss of the sailplane.
