The Federal Aviation Administration (FAA) chief Steve Dickson sent a memo to his staff on Wednesday evening that he will be resigning effective March 31, 2022.Dickson wrote in the memo, "Over the past several years, my family has been a source of tremendous encouragement, strength and support." He continued, "Nevertheless, after sometimes long and unavoidable periods of separation from my loved ones during the pandemic, it is time to devote my full time and attention to them. As I wrote in my letter to President Biden, it is time to go home."The memo was reported by the Seattle Times citing the FAA administrator's mixed emotions and heavy heart in making the decision to resign from the position he has held for just under three years.The decision to resign was reportedly made over the Christmas holiday, and a person close to the situation noted that the U.S. Department of Transportation was told of the decision in January.Dickson, 64, has spent most of the pandemic, and his term with the FAA, residing in Washington D.C. while his family, including a grandson, was living in Georgia and Florida.A former Delta Air Lines pilot, Dickson was appointed by then-President Trump in August of 2019 to serve a five-year term. This appointment came just months after the global grounding of the Boeing 737 MAX. Dickson led the recertification of the aircraft and even flew the aircraft in a test flight.Dickson has faced turbulence since the beginning of his term, leading the FAA through the COVID-19 pandemic and facing the rollout of the 5G C-band service."Steve has been the FAA's steady and skilled captain, and his tenure has been marked by steadfast commitment to the FAA's safety mission and the 45,000 employees who work tirelessly every day to fulfill it," said Transportation Secretary Pete Buttigieg in a statement reported by CNBC.The industry will now look to President Biden to nominate a new leader of the FAA.
