Corroded control rods could fail in flight, causing loss of pitch control and potentially a crash.\n\n**Who must comply:**\nOwners of EMB-110 aircraft with specific serial numbers (roughly serial numbers 110001 through 110376, with some gaps), **unless** the plane has already been modified according to two specific service bulletins (SB 110-27-056 or SB 110-55-022).\n\n**What must be done:**\n- **Immediate action:** Inspect the control rods within 50 flight hours or 10 days after 7 February 1985 (whichever comes first), then re-inspect every 125 flight hours or monthly until the permanent fix is done.\n- **Permanent fix:** Replace the parts within 500 flight hours or 3 months after 30 April 1985 (whichever comes first).\n\n**The bottom line:**\nThis is a \"fix it or ground it\" safety order.
