Gulfstream/Rockwell (Aero) Turbo Commander

The Turbo Commander is a family of twin-turboprop aircraft developed from the original piston-engined Aero Commander line. The aircraft features a distinctive high-wing configuration and has been produced under several corporate identities, including Aero Commander, Rockwell, and later Gulfstream American, reflecting multiple ownership changes over its production history. The Turbo Commander variants, particularly the 690 and 900 series, were widely used in executive transport, air taxi, charter, and utility roles. The aircraft earned a reputation for reliable performance and was popular with fractional ownership programs and corporate flight departments. Production of the Turbo Commander line concluded in the 1980s, though many examples remain in active service around the world. The type is certified under various designations depending on the specific sub-variant, with the ICAO code AC90 applying broadly to the 690/900 series.
