Abstract
This amendment adopts a new airworthiness directive (AD) that requires replacing certain AlliedSignal Inc. VN 411B VHF navigation receivers installed on aircraft if the receivers do not have Modification 21 incorporated. This AD is the result of a report of navigation receiver interference during landing operations. The actions specified by this AD are intended to prevent VHF navigation receiver interference from frequency modulation (FM) radio station broadcasts, which could cause distortion of the navigation audio and deflection of the desired flight path of the airplane during landing operations with possible loss of control of the airplane.
