Very few facets of tower ownership pose the liability to the tower owner that improper lighting, marking, and monitoring do. In Order 13-30 released March 1, 2013, the FCC states, “An aviation accident attributable to an air obstacle occurs every twelve days on average. More than ninety-five percent of those accidents are related to wires, utility poles, or static lines, and eighty five percent of them occur during the day.” Wrongful death or serious injury lawsuits and settlements associated with aircraft impacts to tower structures are commonly in the seven figure range.
