A second notice of claim against the county was filed on behalf of the estate of a man  killed in a November plane crash at the Knox County Regional Airport in Owls Head.

William J. Hannigan Jr., of Portland and Carolyn M. Door of Windham, are the personal representatives of the estate of William J. Hannigan III. They have filed a claim of $2 million against the county and airport.

Hannigan, from South Portland, was a University of Maine alumnus and the pilot of the single-engine Cessna plane.

Also killed was UMaine student David Cheney, 22, of Beverly, Mass and UMaine student Marcelo Rugini, 24, of Rio Grande do Sul, Brazil. All three were members of Lambda Chi Alpha fraternity at the university.

Hannigan and Dorr are represented by Portland attorney Ken Hovermale.

The claim cites negligence of the county and its employees that resulted in the death of Hannigan, including the truck being allowed on the runway by the Knox County Airport and the county with inadequate lighting equipment and other defects.

The aircraft in which Hannigan was piloting collided on the runway with a vehicle driven by Stephen Turner, 62, an employee of Penobscot Island Air, according to previous reports.

The crash that caused Hannigan's injuries and death was “proximately caused by the negligence of County of Knox and its employees included, but was not limited to: failure to adopt and enforce adequate safety rules, regulations and guidelines for the operation, maintenance, or use of the airport facilities and the safety of vehicles and/or aircraft being operated at the airport," the claim states.

The claim also cited failure of the airport “to adequately train, advise, or warn persons using its airport facilities regarding proper and safe methods of use and operation.”

The claim cited the county’s “failure to properly construct, use, design and manage airport runways and related facilities,” and its “failure to properly construct, use, and design and manage its airport runways and related facilities; and failure to properly construct, operate and maintain airport buildings, grounds, and appurtenances to provide for safe passage of aircraft and vehicles being operated on or near runways.”

"The injuries suffered by the pilot, William J. Hannigan Ill, were extreme conscious emotional and physical pain and suffering, death, pecuniary loss, loss of care, comfort, society and companionship of his family and other damages," the file states.

Jeffrey Spear of Nobleboro filed a notice of claim for the estate of Rugini Dec. 20.

Attorney Peter Marchesi of the Waterville law firm Wheeler and Arey, PA, represents Knox County in defense of the claims.

The claim is not a lawsuit but an intent to sue, which must be filed within 180 days of the accident.
