## Summary

We propose to supersede Airworthiness Directive (AD) 2018-19- 18, which applies to certain Airbus SAS Model A300 B4-603, B4-620, and B4-622 airplanes; Model A300 B4-600R series airplanes; Model A300 C4- 605R Variant F airplanes; and Model A300 F4-605R airplanes. AD 2018-19- 18 requires, depending on airplane configuration, a modification of certain angle fitting attachment holes; repetitive inspections for cracking of certain holes of the internal lower angle fitting web, certain holes of the internal lower angle fitting horizontal splicing, the aft bottom panel, and a certain junction area; and related investigative and corrective actions if necessary. Since we issued AD 2018-19-18, we have determined that additional airplanes are affected by the unsafe condition. This proposed AD would retain the actions required by AD 2018-19-18, expand the applicability, and, for certain airplanes, would require repetitive inspections for cracking of certain holes of the center wing box (CWB) lower angle fittings and the CWB lower panel, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
