Vero Beach, Fla.-based Piper Aircraft last month announced a 24-percent increase in third-quarter deliveries and an increase in year-over-year deliveries of 18 percent, resulting in a $25 million increase in billings compared with the same period last year. The manufacturer delivered 195 aircraft, compared with 166 deliveries during the same period last year. Piper will be discontinuing the Saratoga TC and the Arrow, however, due to declining market demand for the two aircraft.
