Missing rivets could weaken the fuselage (the main body of the aircraft) and create a safety risk.\n\n**Who it affects:**\n- Owners and operators of **Beechcraft Model 400A** planes with serial numbers RK-1 through RK-41\n- Owners and operators of **Beechcraft Model 400T** planes with serial numbers TT-3 through TT-20\n\n**What must be done:**\nFollow the instructions in **Beechcraft Mandatory Service Bulletin 2482** — a technical repair guide from the manufacturer.\n\n**When:**\nWithin 100 hours of flying time after 9 December 1993.\n\n**Why it matters:**\nMissing structural rivets compromise the integrity of the aircraft fuselage.
