Piper’s aircraft deliveries and revenues “trended up” for three consecutive quarters, continuing an improving trend in a challenging economy for general aviation aircraft. During the third quarter, Piper delivered 41 aircraft, including eight Meridian turboprop singles, worth $37.2 million. In the first nine months, the Vero Beach, Fla. aircraft manufacturer shipped 127 aircraft, including 20 Meridians, and revenue from new aircraft sales grew to $113.9 million, compared with $106.9 million during the same period last year.
