Plain English Summary

1/10 complexity

This CASA Airworthiness Directive cancels the 1966 AD that required replacing weak lower flying‑wire attachment lugs on Ryan ST Series aeroplanes. Because the original compliance deadline passed decades ago, CASA considers the modification effectively completed and the directive redundant. Owners/operators of Ryan ST aircraft no longer have that historic obligation—this is routine housekeeping.
