We index directives by model, not by serial number or N-number; the record page and the official document say which serials apply.

How to use this page: check the newest directives at every annual, keep the repetitive items on your inspection calendar, and open the official Federal Register text before any work - our summaries are a reading aid, not a determination of compliance.

Airworthiness Directives; HB Flugtechnik GmbH Model HB-23/2400 Sailplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain HB Flugtechnik GmbH (Flugtechnik) Model HB-23/2400 sailplanes. This action requires inspecting (one time) the elevator control push rod tube for dents or bending and replacing the push rod tube, if damaged, inspecting 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. If cracks are found, 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 this AD action. The actions specified by this 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.
