## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to all Fokker Model F.28 Mark 0100 series airplanes, that currently requires replacement of the anti-skid control boxes with improved units. This amendment requires modification or replacement of the anti-skid control boxes with new, improved units, which render the skid control boxes even less susceptible to electromagnetic interference during power-up and power-down transients. This action is prompted by continuing mandatory airworthiness information from a foreign airworthiness authority. The actions specified by this AD are necessary to prevent electromagnetic interference with the anti-skid control system, which could result in reduced brake pressure during low-speed taxiing, and consequent reduced controllability and performance of the airplane. This action is intended to address the identified unsafe condition.
