This is a "domed" inspection plate measuring 4-7/8 inches in diameter, with two spring steel straps; commonly called the "four pronger" inspection plate. Approved for the Citabria series, it is also desired by other owners of aerobatic aircraft. It is ideal for replacing standard inspection plates that have a tendency to come off too easily in the prop wash area under the wing.
