## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain The Lancair Company (Lancair) Models LC40-550FG and LC42-550FG airplanes. This AD requires you to incorporate additional takeoff chart distance values information into the Performance Section of the FAA- approved Airplane Flight Manual (AFM). This AD results from flight testing that revealed that the takeoff distance values for the affected airplanes could not be duplicated. We are issuing this AD to prevent potential impact with terrain or obstruction during takeoff due to incorrect takeoff distance values.
