Despite a year packed with turmoil surrounding safety issues, particularly related to the blowout of a door plug on an Alaska Airlines Boeing 737 MAX flight and subsequent investigations that followed, Whitaker gained respect from politicians on both sides of the aisle.
During his tenure, Whitaker helped address major issues including the nation's air traffic controller shortages and challenges related to aging infrastructure at airports across the United States and referred to the opportunity to lead the FAA as the "honor of a lifetime," according to reports from Politico.
Whitaker leaves behind a strong legacy of providing unwavering leadership despite industry uncertainty and multiple crises.
He is most noteworthy for forcing Boeing to cap 737 MAX production at 38 planes per month as a result of the aforementioned incident when further investigations revealed a problematic safety culture at the manufacturer.
The accident, alongside whistleblower reports of the company brushing aside safety concerns, resulted in an increased level of scrutiny for the Seattle-based planemaker and multiple audits.
Whitaker's resignation, which was not a surprise to most industry analysts, has been met with bipartisan praise mixed with concern over the future.
Democratic lawmakers have been quick to commend Whitaker for his contributions both to the aviation industry and to passenger safety.
Some even indicated that they wished he had not stepped down at all, with Senator Tammy Duckworth stating as follows:
"He’s really working hard to keep the public safe, including important oversight of Boeing, and I’ve heard a lot of bipartisan appreciation for his efforts. So I hope that he does get to stay."
Representative Rick Larsen would further go on to note that Whitaker's background and reputation have earned him extensive respect from both sides of the aisle.
Republican legislators, including Texas Senator Ted Cruz, also acknowledged the administrator's important commitment to safety and noted the importance of ensuring that the next FAA chief continues these efforts.
