Plain English Summary

3/10 complexity

This AD mandates that operators of specific Saab SF340A (S/N 004–159) and SF340B (S/N 160–346) inspect and, if needed, correct nose and main landing gear per Saab Service Bulletin 340‑32‑094. It was issued after bolt‑head shear on retract actuator brackets caused gear extension/retraction problems. Work must be done within 600 landings after 3 February 1994, shifting inspection/repair costs and downtime to affected aircraft operators.
