Abstract
This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR42-500 series airplanes. This action requires a one-time inspection to verify the installation of certain stringer clips at the junction of frame 34 and stringer 6, and installation of stringer clips, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent fatigue cracking in the skin of the fuselage, which could result in loss of pressure inside the airplane.
