CROSSVILLE, Tenn. — After nearly three decades at the helm of his family’s company, Cosby Stone has retired as chief executive officer of TAP Publishing Company, publisher of Trade-A-Plane.

“After serving as TAPPCO’s CEO for 28 years, it’s time for a change in role for me,” said Stone. “I will still be very involved in the company as an owner, as a board member and, at least for this next year, as board chairman.”

Succeeding Cosby Stone as interim CEO is Steve Stone, his brother, who is also a third generation owner.

Adam Strachn, a fourth generation owner, has been appointed CEO Designate.

Strachn, who also serves as legal counsel for TAP, joined the company in 2014 as human resources director.

“I’m very humbled to have been selected to serve in the capacity of CEO Designate,” he said. “I grew up in the company and I’m proud to be a part of it.”
