This is a safety fix to prevent potential fuel system failures that could lead to engine stoppage.\n\n**Who it affects:**\n- **Aircraft models:** All Cessna 210 series planes with serial numbers between 210-57841 to 210-59351, and T210-0001 to T210-0454\n- **People affected:** Aircraft owners, operators, and maintenance engineers responsible for these specific planes\n\n**What must be done:**\n- Follow one of two Cessna Service Letters (SL SE69-9 or SL SE70-25) to make the modification\n- Complete the work within **100 hours of flight time** after 29 August 1969\n\n**Why it matters:**\nFuel pump electrical failures can cause engines to cut out mid-flight.
