Staff ReportVERO BEACH — Citing the need to ‘temporarily redirect resources’ from the PiperJet during the current economic slump, Piper Aircraft said in a letter to stakeholders it will delay rolling out the first of its much-anticipated jets until the middle of 2013.Piper had set a target date of late 2011 or early 2012, but in its letter, posted on aviation Web site www.AVweb.com, the company said the economic conditions and a change in ownership had set back the timetable for completion of its foray into the very light jet market. “Even as the PiperJet program is gaining momentum, we find it necessary to make a change to the PiperJet delivery schedule,” the letter signed by CEO Kevin Gould and President John Becker stated. “Deliveries will now begin in Q2-2013 instead of Q4-2011. Our successful efforts to engage a strategic, long-term ownership group coincided with a drastically weakened business environment. This forced us to temporarily redirect resources from the jet, but the end result is that we are today a better company with a brighter future.”
