Plain English Summary

4/10 complexity

This AD requires operators of certain Boeing 747s with class “C” lower-lobe cargo compartments and incomplete floors to install additional lower-lobe cargo liner panels, following the steps in FAA AD 90-25-08. It was issued after tests showed fire can migrate behind liners and risk structural damage. Affected operators must fund and schedule the retrofit, imposing downtime and maintenance costs while reducing fire risk.
