Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A330-202, -243, -243F, -302, -323, and - 343 airplanes. This proposed AD was prompted by a report that cracks have been found within the ring gears of the slat geared rotary actuators (SGRAs) due to a change in the manufacturing process and inadequate post-production non-destructive testing for potential cracking. This proposed AD would require an inspection to determine the part number and serial number of the SGRAs, and replacement of each affected SGRA with a serviceable part, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
