Plain English Summary

3/10 complexity

Requires operators of Boeing 727‑100/‑200 aeroplanes fitted with specified Argo‑Tech/TRW fuel boost pumps (listed P/Ns) to perform a one‑time detailed visual inspection for loose, damaged or missing breather plugs. If discrepancies are found, the directive requires installing a new breather plug or replacing the pump per the cited Boeing/Argo‑Tech manuals, and forbids installing those pump P/Ns unless inspected and corrected. It affects aircraft operators, maintenance organisations and parts installers and addresses an identified unsafe condition.
