Weatherly Aviation

Weatherly Aviation Company, formed in California on March 28, 1961, is an American agricultural aircraft manufacturer. Initially, the company was focused on modifying surplus Fairchild M-62 Cornell military trainers for agricultural purposes, such as the Weatherley WM-62C.

As one of three American agricultural aircraft manufacturers, the company produces new aircraft and has been doing so since 1976. Its well-known current product is the Weatherly 620-B aircraft, designed for small-grain farming, with plans to resume production of the 620-B and 620-BTG models. The company also offers technical services and parts for its traditional market.
