Plain English Summary

4/10 complexity

This directive requires operators of SAFT Nickel‑Cadmium aircraft batteries (two SAFT part numbers manufactured before December 1997) to replace battery terminal screws, confirm the cells match the approved design and replace any non‑conforming cells, and to fit a compliance label — all performed per SAFT Aviation Batteries Service Bulletin A00027 Rev G. Compliance is due at the next scheduled battery maintenance within three months or within 15 months, whichever is sooner. The stated safety purpose is to prevent shorting or explosion that could cause loss of emergency electrical power.
