The Citation S550-based Sierra Super S-II completed a 36-minute maiden flight September 26 at Sierra’s Uvalde, Texas modification center. The flight demonstrated the “dramatic” improvements of the dual fadec-controlled Williams FJ44-3A engines, the company said.

The aircraft reached 18,000 feet in three minutes and 45 seconds.
