If left unchecked, this could cause the flaps to fail during flight, potentially leading to loss of control. The directive mandates:\n- An **initial inspection** before 19 September 1997\n- **Follow-up inspections** as specified in the manufacturer's service bulletin\n\n**Who must comply:** Anyone operating or maintaining a Short SD3-60 aircraft in Australia.\n\n**Key point:** This is a **safety-critical maintenance requirement**, not optional.
