At LIMA, the Sheltair improvements will include upgrading two hangars, improving drainage, updating customer parking, repaving ramp and tie-down areas, and removing old fuel tanks.

"General aviation serves as a crucial transportation link for Long Island businesses and the economy as a whole, with Long Island MacArthur Airport playing a vital role in supporting that function," said Todd Anderson, Sheltair's senior vice president for real estate and development, in the release.

"Our sustained commitment to serving that segment of the aviation community continues to be self-evident through our investment under way at Long Island MacArthur, as well as our other properties in the New York metro area."

This new project brings Sheltair's investment in its LIMA facility to $1.1 million total.
