Plain English Summary

2/10 complexity

This directive mandates a one‑time inspection, within 25 hours time‑in‑service after 10 November 1981, of specific shackles (P/N 486‑566 / MS 20115‑5) used on rudder cable/horn and upper seat belt/cable attachments of Piper PA‑36‑285/300 and PA‑36‑375 aeroplanes listed in Piper Service Bulletin No. 729 (or later revisions).

It affects owners/operators and maintenance personnel, who must pay for and schedule the inspection; it aims to detect cracking before failure but may cause short‑term downtime and relies on the service bulletin to define scope.
