Summary
We propose to supersede Airworthiness Directive (AD) 2016-25- 03, which applies to certain Airbus Model A300 F4-600R series airplanes. AD 2016-25-03 requires repetitive high frequency eddy current (HFEC) inspections of the aft lower deck cargo door (LDCD) frame forks; a one-time check of the LDCD clearances; and a one-time detailed visual inspection of hooks, eccentric bushes, and x-stops; and corrective actions if necessary. Since we issued AD 2016-25-03, we have determined that accomplishing a new frame fork repair or reinforcement would allow an extension of the repetitive inspection intervals as would a frame fork replacement. This proposed AD would retain the actions required by AD 2016-25-03, with revised corrective actions and compliance times. We are proposing this AD to address the unsafe condition on these products.
