Those aircraft that have the forging replaced now may have to do it all again when better forgings are available.
Excerpt from the AD.
"The FAA considers this AD interim action. The inspection reports that are required by this AD will enable the manufacturer to obtain better insight into the nature, cause, and extent of the cracking, and eventually to develop final action to address the unsafe condition. Once final action has been identified, the FAA might consider further rulemaking."
"Develop Final Action" could mean the re-design and manufacturing processes of the pickle forks.
