WASHINGTON -- Randy Babbitt resigned as administrator of the Federal Aviation Administration on Tuesday after being charged over the weekend with driving while intoxicated.

"Today I submitted my resignation to Secretary Ray LaHood and it has been accepted," he said in a written statement. "Serving as FAA Administrator has been an absolute honor and the highlight of my professional career. But I am unwilling to let anything cast a shadow on the outstanding work done 24 hours a day, 7 days a week by my colleagues at the FAA."

Police in Fairfax, Va., a suburb of Washington, said Babbitt, 65, was driving on the wrong side of the road when he was stopped at 10:30 p.m. ET Saturday. Babbitt, who was alone in the vehicle, was found to be intoxicated, police said, and was held at a detention center, where he was charged and released on a personal recognizance bond.

Police said that Babbitt wasn't involved in an accident and that he cooperated with police.

Babbitt was appointed to lead the FAA in 2009. LaHood praised Babbitt on Tuesday for being an "outstanding leader."

"I'm proud to say that we have the safest aviation system in the world, and thanks to Randy's stewardship, it became safer and stronger," he said in a written statement.

Babbitt apparently delayed telling administration officials about the arrest. White House spokesman Jay Carney said President Barack Obama and Transportation Department officials learned of the arrest Monday afternoon, about an hour before a 1:30 p.m. statement was released saying Babbitt had been placed on leave at his request.

Separately, Fairfax City police issued a statement on the arrest to the media at about noon Monday, which their policies require in cases where a public official has been arrested. Police refused to disclose the results of Babbitt's blood alcohol test. The legal limit is .08.

LaHood has aggressively campaigned against drunken driving, and is working with police agencies and safety advocates on an annual holiday crackdown on drinking and driving later this month. Safety advocates credit LaHood with doing more to raise the visibility of human factors in highway safety — including drunken driving, drivers distracted by cell phone use, and parents who fail to buckle in their children — than any previous transportation secretary.

Deputy FAA Administrator Michael Huerta will serve as acting administrator, the Transportation Department statement said. In recent months Huerta has been leading the FAA's troubled NextGen effort to transition from an air traffic control system based on World War II-era radar technology to one based on satellite technology.

Babbitt was a former airline captain and internationally recognized expert in aviation and labor relations when Obama tapped him in 2009 to head the FAA. He was a pilot for the now-defunct Eastern Airlines for 25 years, and had served as president of the Air Line Pilots Association. As head of ALPA, he championed the "one level of safety" initiative implemented in 1995 to improve safety standards across the airline industry.

Babbitt's nomination in 2009 was warmly received by both industry officials and airline unions. His easy manner and insider's knowledge of the airline industry generated respect in Congress, where he regularly testified on safety issues and in support of NextGen.

Babbitt took over at the FAA when the agency was still reeling from the exposure of widespread safety gaps in the regional airline industry. The problems were revealed by a National Transportation Safety Board investigation of the February 2009 crash of a regional airliner near Buffalo, N.Y., that killed 50 people.

Babbitt and LaHood promised to immediately implement a series of safety initiatives. At Babbitt's urging airlines adopted a series of voluntary safety measures, although safety advocates say voluntary measures aren't enough. The FAA under Babbitt has also initiated several efforts to craft major new safety regulations, ranging from preventing pilot fatigue to boosting experience levels and training of airline pilots.

But Babbitt has struggled to realize several of those safety proposals. Some proposals have stalled as industry opponents lobbied White House officials against the proposed regulations, saying they would cost too much or be too burdensome.

The biggest crisis of Babbitt's FAA tenure occurred last spring over a period of several weeks when nine air traffic controllers were allegedly caught sleeping on the job or were unresponsive to radio calls while on duty. The head of the FAA's Air Traffic Organization was forced to resign during the ensuing uproar.

As the FAA's top official, Babbitt has the final say in disciplinary proceedings involving controllers who violate the agency's drug and alcohol regulations.
