Eyerly Aircraft Company was an amusement ride manufacturing company in Salem, Oregon, founded by Lee Eyerly in 1930. The company originally intended to design flight simulators for the aircraft industry but shifted to amusement rides after an early simulator, called Orientator, became a popular pay-per-ride attraction with the public. The company manufactured rides until 1985 and went bankrupt in 1990, following a fatal accident in 1988 on a ride built by the company.

Lee Eyerly founded Eyerly Aircraft Company in 1930 to manufacture two inexpensive ways to train pilots which he devised when the Great Depression hit: the Whiffle Hen,^[1] a plane which only burned two US gallons (8 L) of fuel per hour of flight, and a ground-based flight training device patented under the name "Orientator". The Orientator consisted of a small airplane suspended in what looked like the tines of a giant tuning fork. Air from the electrically driven propeller passed over the wings and rudder, and the operator controlled the movements of the plane in a manner similar to a real aircraft.^[2] The Orientator was produced commercially and eventually renamed "Acroplane".

A salesman approached Eyerly about selling Acroplanes to carnivals and parks as an amusement ride after noticing several stored on the lot outside Eyerly's shop. While Eyerly was initially skeptical, he agreed to a deal which led to selling about 50 Acroplanes as an amusement ride. The following year, Eyerly changed the company's focus from aircraft to amusement rides based on the successful sales.^[2] Eyerly developed and patented numerous amusement rides which would become staples of carnival midways, including The Loop-O-Plane (1933),^[2][3] the Roll-O-Plane,^[4] the Fly-O-Plane and the Rock-O-Plane (1947).^[5][6] Perhaps their most popular design was the Octopus,^[4] which resulted in later variations: the Spider and the Monster. Two of the company's kiddie carousel rides were the Midge-O-Racer and Bulgy the Whale.^[7]

Although Eyerly's manufacturing business became amusement rides, the name of the company remained Eyerly Aircraft Company.^[7]

A partial list of the Eyerly Aircraft Company rides and their locations follows.

Eyerly Aircraft Company continued to produce amusement rides until 1985.^[72] A fatal accident occurred at the Broward County Fair in Florida in 1988, when an arm (carrying four rider baskets) of a Monster ride snapped along an existing crack that had been painted over years before, and had then been missed in inspections.^[73] A 17-year-old girl died of head injuries when the basket she was riding in collided with another as it fell to the ground, and at least six others were injured.^[73][74] A wrongful death lawsuit was brought against the ride's owner and county fair operator for failure to properly inspect and reinforce the ride, despite Eyerley's warning bulletins recommending maintenance.^[75][74] Following the lawsuit against the operator, Eyerly Aircraft's insurance premiums increased and became unaffordable; the company filed for bankruptcy and closed in 1990.^[72] The rights to their rides were later purchased by Oregon Rides Inc.^[6]
