Plain English Summary

3/10 complexity

This directive requires owners/operators of SAAB SF340 aeroplanes (serials -004 through -106) to have a small electrical jumper fitted to the mid‑level and tank‑full fuel‑level optical sensors, performed exactly per SAAB Service Bulletin SF340‑28‑006, to prevent hazardous lightning effects on the fuel‑sensing system. Maintenance organisations must carry out and operators pay for the one‑off retrofit; compliance was required by 6 October 1988.
