Plain English Summary

2/10 complexity

This directive requires a rigging revision to the fairing‑mounted escape‑slide firing mechanism on certain Boeing 747s (per Boeing SB 747‑25A2581). Owners/operators of affected serial numbers must have the work done within 1,200 flight hours after 31 December 1981.

The change addresses reduced fairing door travel that can interfere with the firing mechanism and prevent slide inflation; operators are responsible for scheduling and funding the work and following the referenced service bulletin.
