## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to all Airbus Model A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) series airplanes, that currently requires repetitive inspections to detect cracking of the upper radius of the forward fitting of frame 47, and repair if necessary. This amendment retains those requirements but shortens the initial compliance time and the repetitive inspection intervals. This amendment also expands the applicability to include additional airplanes. This amendment is prompted by issuance of mandatory continuing airworthiness information by a civil airworthiness authority. The actions specified by this AD are intended to detect and correct such fatigue cracking, which could result in propagation of the cracking to the rear fitting and reduced structural integrity of fuselage frame 47.
