Summary
This document revises an earlier proposed airworthiness directive (AD), applicable to all Airbus Model A300 B4 series airplanes and all Airbus Model A300-600 series airplanes, that would have superseded an existing AD that currently requires a one-time high frequency eddy current inspection to detect cracking of the splice fitting at fuselage frame (FR) 47 between stringers 24 and 25; and corrective actions if necessary. The original NPRM proposed to require new repetitive inspections of an expanded area, and would have added airplanes to the applicability in the existing AD. This new action revises the original NPRM by adding airplanes to the applicability. The actions specified by this new proposed AD are intended to detect and correct cracking of the splice fitting at fuselage FR 47, which could result in reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
