Piper Aircraft ended 2012 with nearly $149 million in annual revenue from new aircraft sales, up more than 13 percent from the previous year. This revenue increase was the result of a 16-percent rise in deliveries last year to 158 aircraft, 22 more than in 2011. Piper delivered 93 of its top-line M-Class aircraft–including 39 Meridian turboprop singles–compared with 82 the previous year, which also helped the annual revenue mix. Meanwhile, the company named Jack Mill as vice president of engineering today. He had been leading the Piper engineering team in an interim role for the past several months.
