Plain English Summary

4/10 complexity

This airworthiness directive (AD/DC4/11) requires replacement of AN‑type bolts in the vertical stabiliser attachment fittings on Douglas DC‑4 series aeroplanes. Issued under CASA/Part 39, it makes the replacement mandatory for owners/operators and maintenance providers, who must follow one of three referenced technical documents for the procedure. The AD addresses a safety risk but imposes parts, labour and downtime costs and relies on external service/airworthiness documents for compliance detail.
