Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to all GROB-WERKE (GROB) Model G120A airplanes. This proposed AD would require you to modify the flight control system operating levers. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this proposed AD are intended to prevent failure of a ball bearing in flight control system operating levers. Such failure could lead to reduced control or loss of control of the airplane.
