## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to all Fokker Model F.28 Mark 0070 and 0100 series airplanes, that requires installation of new, improved bonding jumpers on the horizontal stabilizer. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to ensure adequate electrical bonding between the horizontal and vertical stabilizers. Inadequate electrical bonding, in the event of a lightning strike, could cause electrical arcing, and result in damage to the hydraulic lines and consequent failure of the hydraulic systems.
