Nextant Aerospace announced today at the NBAA Convention that it has received STC approval for its Rockwell Collins Pro Line 21 flight deck retrofit for Beechjet 400s and Hawker 400XPs. The Pro Line 21 retrofit, consisting of two large LCD primary flight displays and one large LCD multifunction display, is priced at $390,000. An additional second MFD can be installed for about $50,000, and any orders placed during the NBAA Convention for this fourth screen will receive a 50-percent discount on this option. According to Nextant CEO Kenneth Ricci, the company has received Pro Line 21 upgrade orders for five aircraft. Installation takes three to four weeks, Ricci said, and customer deliveries are to begin next month. Nextant, based in Richmond Heights, Ohio, is also busily working on certification efforts for its 400Next remanufactured 400/400XPs with Pro Line 21 avionics and new Williams FJ44-3AP engines. Ricci said that the remanufactured aircraft are now priced at $3.9 million, which is a $1 million price reduction due to lower costs to obtain pre-owned Beechjets that the company can refurbish. Nextant says it has orders for 15 copies of the 400Next.
