Summary
We propose to supersede Airworthiness Directive (AD) 2018-20- 06, which applies to certain Airbus SAS Model A300 F4-600R series airplanes. AD 2018-20-06 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 2018-20-06, we determined certain compliance times need to be revised, depending on frame fork configuration. This proposed AD would continue to require the actions of AD 2018-20-06 and would require new compliance times, depending on frame fork configuration. We are proposing this AD to address the unsafe condition on these products.
