## Abstract

The FAA is superseding Airworthiness Directive (AD) 2019-19- 06, which applied to certain Airbus SAS Model A330-202, -243, -243F, - 302, -323, and -343 airplanes. AD 2019-19-06 required an inspection to determine the part number and serial number of the slat geared rotary actuators (SGRAs), and replacement of each affected SGRA with a serviceable part. This AD continues to require replacement of each affected SGRA with a serviceable part, expands the applicability to include all airplanes on which the affected part may be installed, and also prohibits installation of an affected part; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a report that cracks have been found within the ring gears of the SGRAs due to a change in the manufacturing process and inadequate post-production non-destructive testing for potential cracking, and a determination that the requirements of AD 2019-19-06 may not ensure the permanent removal from service of affected SGRAs. The FAA is issuing this AD to address the unsafe condition on these products.
