Cessna to Re-Enter Small-Aircraft Market: The Wichita, Kan.- based plane maker said the decision was made because Congress passed a law in August restricting liability for manufacturers of smaller aircraft. Cessna Aircraft Co. had stopped making the single-engine planes in 1986 because of product liability lawsuits alleging faulty construction. The company said it believes that by 1997 it will be selling 2,000 of its classic single-engine, fixed-wing planes annually, or $300 million a year in new sales. Cessna has said its revenue last year was more than $800 million, most from the sale of business jets. The first new single-engine unit is expected to roll off the assembly line at a new facility in Independence, Kan., in the fall of 1996.
