## Abstract

The FAA adopts a new airworthiness directive (AD) for all GROB-WERKE (GROB) Model G120A airplanes. This AD requires you to modify the flight control system operating levers. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this AD to prevent failure of a ball bearing in the flight control system operating levers. Such failure could lead to reduced control or loss of control of the airplane.
