RICHMOND HEIGHTS, OH-Aircraft remanufacturer Nextant Aerospace has announced that the Williams FJ44-3AP engine that will power the world’s first remanufactured business jet has received FAA certification.

“This was the last significant hurdle as we work towards the final STC for the 400XT,” says President Jim Miller. “This engine represents a significant evolution in technology and it is one of the key components that will make the 400XT the most efficient and cost effective aircraft in its class.”

The Williams FJ44-3AP is a Full Authority Digital Engine Control (FADEC) turbofan engine and it will replace the outdated Pratt & Whitney JT15D-5 on the new 400XT. Key product features for the FJ44-3AP include:

  • Thirty two percent more fuel efficiency than the original Pratt and Whitney JT15D-5;
  • Savings of 240 pounds, which allows for better thrust-to-weight ratios; and
  • Lower Engine Maintenance Costs: Nearly 30% less on a cost per hour basis compared to the JT15D-5.

    During a press conference at EBACE, Nextant Aerospace reported that the engine performed flawlessly during flight testing. The company also outlined a timeline that anticipates the conclusion of FAA required test flights this week. Nextant has started manufacturing the 400XT in anticipation of the final STC which they expect to receive by the end of the quarter. This will allow retail deliveries to begin in July.
