The affected planes are those fitted with either:\n- Hoskins part number 30-0187-21, or  \n- Grimes part number 30-0669-1\n\nThe required fix must follow the instructions in **Beechcraft Service Instruction No. 0800-362** (a technical bulletin from the manufacturer).\n\n**Who it affects:** \n- Owners and operators of Beechcraft 60 and A60 models with serial numbers P-3 through P-222\n- Maintenance organisations servicing these aircraft\n\n**Why it matters:** Wing strobe lights are critical safety equipment — they make aircraft visible to other planes, especially in low-light conditions.
