AD NUMBER: 2019-16-11

PRODUCT: Certain Airbus SAS Model A300 F4-600R series airplanes.

ACTION: Final Rule.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2018-20-06, which applied to the airplanes listed above.

AD 2018-20-06 required 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; a one-time detailed visual inspection of hooks, eccentric bushes, and x-stops; and corrective actions if necessary.

This AD retains the actions of AD 2018-20- 06 and requires new compliance times, depending on frame fork configuration. This AD was prompted by a report of two adjacent frame forks that were found cracked on the aft LDCD of two airplanes during scheduled maintenance, and a determination that certain compliance times need to be revised.

DATES: This AD is effective October 2, 2019.

COST: The FAA estimates that this AD affects 58 airplanes of U.S. registry. Operators may incur the following costs in order to comply with this AD:

• Retained actions from AD 2018-20-06: Labor: 17 work-hours × $85 per hour = $1,445 per aircraft.
• On-Condition Costs: Up to 65 work-hours × $85 per hour = Up to $5,525. Parts: Up to $10,000. Cost per airplane: Up to $15,525.
