David Stone is stepping down as head of the U.S. Transportation Security Administration in June.
The announcement was made April 8 by TSA spokesman Mark Hatfield. Stone will be the third top administrator to leave TSA since the agency was created three years ago.
Stone was in the U.S. Navy from 1974 until his April 2002 retirement at the rank of rear admiral. Stone has led the TSA since Dec. 4, 2003, the first seven months as acting administrator.
As TSA’s first federal security director at the Los Angeles International Airport, he trained and deployed the largest federalized work force in the United States two weeks before the operation’s deadline and put into place a 100 percent electronic checked-baggage screening program.
