Express Series 90

The Express Series 90 is an American homebuilt aircraft that was designed and produced by the Express Aircraft Company of Olympia, Washington, introduced in the late 1980s. When it was available the aircraft was supplied as a kit for amateur construction.

Design and development
The Express Series 90 is a development of the earlier Wheeler Express designed by Ken Wheeler. It incorporates a 20% larger tail which gives it a wider center of gravity range, while also enhancing pitch and yaw stability.

The aircraft features a cantilever low-wing, a four-seat enclosed cabin, fixed tricycle landing gear with wheel pants and a single engine in tractor configuration.

The Series 90 is made from composites. Its 31.00 ft span wing mounts flaps and has a wing area of 130.00 sqft. The cabin width is 46 in. The standard engine used is the 300 hp Lycoming IO-540 four stroke, air-cooled, six cylinder powerplant.

The aircraft has a typical empty weight of 1840 lb and a gross weight of 3200 lb, giving a useful load of 1360 lb. With full fuel of 92 u.s.gal the payload for pilot, passengers and baggage is 808 lb.

The manufacturer estimated the construction time from the supplied kit as 2000 hours.

Operational history
In December 2013 three examples were registered in the United States with the Federal Aviation Administration.
