## Abstract

The FAA adopts a new airworthiness directive (AD) for all CENTRAIR 101 series gliders with other than elevator or aileron part number (P/N) SY991A hinge pins installed. This AD requires you to replace any installed elevator or aileron hinge pins that are not P/N SY991A hinge pins with P/N SY991A pins. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. We are issuing this AD to replace incorrectly heat-treated elevator or aileron hinge pins, which could result in failure of the elevator or ailerons. Such failure during takeoff, landing, or flight operations could lead to loss of glider control.
