Rockwell International 500s

Twin Piston

The Rockwell Aero Commander 500S, marketed as the Shrike Commander, represents the refined evolution of a twin-engine piston design that first flew in 1948 and became a workhorse for corporate, charter, and utility operators throughout the latter half of the twentieth century. Built by what became Rockwell International after several corporate mergers, the 500S variant introduced in the 1970s featured fuel-injected Lycoming IO-540 engines producing 290 horsepower each, giving the aircraft a maximum cruise speed around 215 knots and a service ceiling of 19,600 feet. Its high-wing configuration and robust landing gear made it popular for operations into unimproved strips, while the pressurized cabin variants appealed to business operators seeking comfort without the operating costs of turbine power. The Shrike Commander earned a reputation for docile handling and solid single-engine performance, though like many piston twins of its era it demanded respect during engine-out scenarios at high weights. Today the type survives primarily in training fleets, cargo operations, and with owner-pilots who value its combination of speed, payload, and relatively straightforward maintenance compared to more complex twins. SkyMeter has tracked 10 flights across 3 airframes and 3 operators, with SMITH STEVEN J the largest observed operator.
