WASHINGTON — The acting administrator of the Federal Aviation Administration, Billy Nolen, on Friday said he will depart this summer, worsening a leadership void at the agency.
The departure of Mr. Nolen, a former pilot and airline industry group executive, was announced in a letter to F.A.A.
The aviation regulator has been without permanent leadership since Stephen Dickson, a former Delta Air Lines executive who was appointed by President Donald J. Trump, stepped down a year ago.
Last month, President Biden’s pick to lead the F.A.A., Phillip A. Washington, withdrew his name from consideration after a series of attacks from Republicans on his qualifications to hold the post.
They had argued that Mr. Washington, the chief executive of Denver International Airport, lacked sufficient aviation experience, and raised questions about his connection to a corruption investigation in Los Angeles.
