2004-23-20 MANUFACTURER: Airbus SUBJECT: Airworthiness Directive 2004-23-20 SUMMARY: The FAA is superseding an existing
airworthiness directive (AD) that applies to all Airbus Model A300
B4-601, A300 B4-603, A300 B4-620, A300 B4-605R, A300 B4-622R, and
A300 F4-605R airplanes. That AD currently requires repetitive
inspections for cracking in the area surrounding certain fuselage
attachment holes, installation of new fasteners for certain
airplanes, and certain follow-on corrective actions if necessary.
This new AD requires modifying certain fuselage frames, which would
terminate certain repetitive inspections. This AD also adds
airplanes to the applicability. This AD is prompted by the
development of a modification intended to prevent cracking of the
center section of the fuselage, which could result in a ruptured
frame foot and reduced structural integrity of the airplane.
