The FAA has confirmed that Lirio Liu, the executive director of the Aircraft Certification Service, will retire next month. "Lirio Liu plans to retire from the FAA at the end of June after 33 years with the agency. The FAA has not selected a permanent replacement," the agency said in a statement. "We continually develop leaders to ensure a seamless transition when senior officials depart." Liu is also the co-chair of the End Aviation Gasoline Lead Emissions and will presumably be leaving that post.
