Plain English Summary

3/10 complexity

This amendment mandates operators of specified SAAB SF340A/340B aeroplanes to carry out the inspections and maintenance set out in Swedish LFV AD 1‑049 Revision A, with technical detail in SAAB service bulletin 340‑54‑027 Rev 1, because bolts and collars on the lower drag strut fitting have been losing torque. It affects the listed serial numbers, places costs and downtime on operators, and only changes the Australian compliance date to 14 November 1991.
