The successful 188 Agwagon agricultural aircraft were Cessna's only purpose designed agplanes. Cessna's Model 188 resulted from extensive research and consultation with agricultural aircraft operators conducted in the early 1960s. The design Cessna settled upon was of the conventional agricultural aircraft arrangement with a braced low wing (unique among Cessna singles) with seating for the pilot only. Like other ag aircraft the chemical hopper is of fibreglass and the rear fuselage is of semi monocoque construction and sealed to reduce the potential for damage from chemical contamination.
The Motat A188 Agwagon was the first 300 hp (250 kW) Cessna 188 and was powered by the Continental IO-520-D and featured a 200 US gallon chemical hopper. It was introduced in 1966 alongside the lower-horsepower AGpickup at a base price of $18,950. The A188 was named the AGwagon in 1972. It ceased production in 1980.
Cessna C 188 Agwagon ZK-COO is displayed in the colours of Phoenix Aviation of Gore. It was the second Agwagon to be registered in New Zealand, and was one of a large number of Agwagon's to be imported by Rural Aviation in 1966/67 (34 of them?), and they were nearly all painted in a similar colour scheme to the above but with red and black stripes. ZK-COO was first registered in February 1966 and was withdrawn from use at Ardmore in 1977 and was cancelled in July 1978.
The aircraft was stripped down the steel frame, sand blasted and repainted. An engine and propeller were obtained and fitted and slowly the entire aircraft restored and repainted. The wings were painted stripped, checked for corrosion, repaired where necessary, and repainted. All of this undertaken by volunteers working on Wednesdays and Sundays. The result has been excellent.
The aircraft was then placed on display in the main hanger beside the Solent for some time before being moved outside while the new aviation building completed. It was then suspended from the ceiling for display.
ZK-COO is a great part of a fleet of topdressing aircraft in the Motat collection including other classics such as the Fletcher, Airtruk and Tiger Moth.
