Plain English Summary

3/10 complexity

This directive mandates that operators inspect A6441 FN-606 and FN-606A propeller blades per Part 2 of Allison CSL 240, Revision 3, at intervals not exceeding 3,250 flight hours. Operators or their maintenance organisations must schedule, carry out, and fund the inspections and any follow-on work. It matters because the manufacturer added the requirement to reduce blade-failure risk, trading inspection costs and downtime for improved safety.
