Aero-TV: CJ4 Precision Assembly Pt. 2 – Cessna’s Mating Process for Section Alignment

At Cessna Aircraft, “safety begins with a durable airframe.” Each airframe is stress-tested five times the aircraft’s standard lifetime; yet, Cessna’s renowned safety and reliability begins on the production line. State-of-the-art technology allows employees to create replicable, seamless assembly for each new aircraft on the line. In the second of his four-part series, Baker describes Cessna’s CJ4 mate and alignment tools to assure precision assembly for every aircraft on the production line.

The Citation CJ4 will debut two new dual-channel, FADEC controlled Williams International FJ44-4A engines. The turbofan engines each produce 3,400 pounds of takeoff thrust, allowing the aircraft to takeoff at max weight with as little as 3,300 feet of runway. After takeoff, the Citation CJ4 is capable of a direct climb to 45,000 feet in just 28 minutes. In addition, the CJ4 will offer increased performance over earlier projections with a maximum cruise speed of more than 450 knots and a maximum range of over 2,000 nautical miles.

On February 2nd, 2010, Cessna announced the completion of all certification testing. Three Citation CJ4 test aircraft completed over 1,100 flights with more than 2,000 flight hours accumulated. With the CJ4 in the final stages of F.A.A. type certification approvals, the company expects deliveries to begin in late 2010.
