William "Bill" R. Weaver, a more than 40-year aviation industry veteran and former co-owner of Million Air White Plains in New York, died on April 12. He was 66.

A commercial pilot and former Air National Guard mechanic, Weaver and Mike Mason grew up around the FBO and flight school at Westchester County Airport (HPN) that was owned by their fathers, and in 1983 purchased the business from them. In 2007 they announced a rebranding of their Westair FBO to Million Air, along with an expansion. Weaver also served the industry as a volunteer on the board of the Westchester Aviation Association and as a member of the Patient Air Lift Services (PALS) charity.

In addition to his aviation career, Weaver was an 18-year member of North Castle town board, including two years as town supervisor. For 13 years he was a member of the fire department in his hometown of Armonk.

Weaver is survived by his wife, Susan Trumm Weaver, and sons, Darrell (Jaclyn), Devin, and Brandon Weaver. A celebration of his life is planned for 4 to 8 p.m. today at Million Air White Plains.
