The FAA on Friday granted type certification to Cessna’s Model 525 Citation CJ1+, keeping the program on schedule and bringing the aircraft one step closer to customer deliveries, which are expected to begin in the fourth quarter. The $4.1 million CJ1+ offers more performance, new Collins Pro Line 21 integrated avionics, enhanced cabin features and expanded standard equipment compared with the CJ1. The new jet is powered by two Williams FJ44-1AP dual-channel FADEC-controlled turbofans. At 41,000 feet, the CJ1+ can travel more than 20 knots faster than the CJ1, Cessna said. In addition, a 100-pound gross weight increase of the CJ1+ allows it to carry more payload over greater distances. NBAA IFR range with one pilot and three passengers is 1,285 nm. Standard CJ1+ features in the cabin include a left side flushing toilet with seat belt, “deluxe” refreshment center, LED indirect lighting and over-water life vests.
