Do the New Engines of the Hawker 900XP Make a Difference?

The short answer is: yes. The Hawker 900XP’s advantage over its predecessor, the Hawker 850XP can be attributed to its TFE731-50R engines, flat-rated to 4,660 pounds of thrust apiece. Although they produce the same amount of thrust as the TFE731-5BR models used on the Hawker 850XP, they burn less fuel and require maintenance much less often. The inspection interval for the Hawker 900XP’s engines is 6,000 cycles, a marked improvement over the 4,200 cycle inspection interval of the engines on the Hawker 850XP.
