Hawker 800 Series

The Hawker 800XP, 850XP, and 900XP are among the most successful midsize business jets ever built, powered by the proven Honeywell TFE731. Haggan Aviation's technicians know the 800 platform inside and out — along with the legacy 125, 600, 700, and 1000 airframes that share its heritage.

Hawker 800XP
Midsize · 1995–2005

The definitive midsize Hawker. "XP" for Extended Performance — uprated TFE731-5BR engines and an improved wing delivered better field, climb, and cruise performance. One of the best-selling midsize jets in history.
