Plain English Summary

3/10 complexity

This AD mandates that certain Airbus A319/A320/A321 aeroplanes (those serial‑numbers listed in the directive) have the pylon fuel return‑line connection and pylon drain sealant inspected and corrected per Airbus Industrie AOT 28‑04 Rev 1, to be done within 500 flying hours from 1 Jan 1993.
