Airworthiness Directives; British Aerospace (Jetstream) Model HS 748 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace (Jetstream) Model HS 748 series airplanes. This action requires a one-time visual inspection of the retraction jack mounting brackets in the nose landing gear bay to determine the type of attachment bolts installed on the bracket bearing caps, and replacement of any incorrect bolt with a serviceable bolt of the correct type. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent failure of the bearing cap attachment bolts, which could result in detachment of the bearing caps and consequent collapse of the nose landing gear on landing.
