When an AD is issued (or superseded), aircraft operators must comply with the current version to keep their aircraft legally flyable. This document serves as a historical reference point showing that the old safety requirement (AD/PL 12/9) is no longer in force and has been updated by AD/PL-12/15. Anyone relying on the old directive needs to check the replacement for current requirements."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The entry explicitly records that AD/PL 12/9 has been superseded by AD/PL-12/15.
