The Wall Street Journal earlier reported that Dickson was the White House pick and that an announcement could come as early as Tuesday.
The FAA declined to comment.
Earlier this month, multiple media reports said Dickson was expected to be named the new FAA chief. Those reports came just days before Ethiopian Airlines Flight 302 crashed and killed all 157 people on board.
Earlier Tuesday, Transportation Secretary Elaine Chao sent a memo to the department’s inspector general, formalizing a request for an audit of the FAA’s certification of the Boeing planes.
Dickson, who previously served as senior vice president of flight operations at Delta, retired from the company on Oct. 1. The executive was a 27-year veteran of the company and had previously served as a U.S. Air Force officer. Dickson is a graduate of the Air Force Academy and F-15 fighter pilot.
