Boeing said Sunday it knew of a safety alert flaw in the cockpit of its 737 MAX jetliners months before the first of 2 fatal crashes involving the now-grounded aircraft, but it didn't immediately notify regulators.

Details: The issue concerns a warning light in the cockpit, known as the AOA Disagree alert. This alert is meant to notify the flight crew that two angle-of-attack (AOA) sensors are providing data that disagree with each other, which suggests one is erroneous. The company said in a statement the aircraft’s "display system software did not correctly meet" the AOA alert requirements in 2017 — well before October's Lion Air crash in Indonesia, which killed 189 people.

The big picture: A Federal Aviation Administration official told Reuters that Boeing waited 13 months before reporting the issue in November. Southwest Airlines told CNBC that Boeing didn't inform it about the issues until after the Indonesia crash. It's unclear if Boeing reporting the warning light issues could've prevented the Lion Air crash or March's Ethiopian Airways disaster, which killed 157 people.

What they're saying: Boeing said neither the AOA indicator nor the AOA Disagree alert identified in the flaws are necessary for the safe operation of a plane. "They provide supplemental information only, and have never been considered safety features on commercial jet transport airplanes," it said.

Detailing the issue, Boeing said in 2017, "within several months after beginning 737 MAX deliveries, engineers at Boeing identified that the 737 MAX display system software did not correctly meet the AOA Disagree alert requirements."

Why it matters: Boeing is the world's largest aerospace company, and its fortunes can ricochet throughout the economy, per Axios science editor Andrew Freedman. As federal investigators examine the two crashes and evaluate the safety of the plane, this latest issue raises questions about Boeing’s candor with regulators.

The 737 MAX's success is essential to Boeing's future, given that the airline has thousands on order.

White House stands by imperiled Tanden nomination after Senate panel postpones hearing

The Senate Homeland Security Committee is postponing a confirmation hearing scheduled Wednesday for Neera Tanden, Axios has learned, a potential death knell for President Biden's nominee to lead the Office of Management and Budget.

The latest: Asked Wednesday afternoon whether Tanden has offered to withdraw her nomination, Psaki told reporters, "That’s not the stage we’re in." She noted that it's a "numbers game" and a "matter of getting one Republican" to support the nomination.

Acting Capitol Police chief: Officers were unsure of lethal force rules on Jan. 6

Acting U.S. Capitol Police Chief Yogananda Pittman wrote in prepared remarks for a House hearing on Thursday that officers in her department were "unsure of when to use lethal force" during the Jan. 6 insurrection.

Why it matters: Capitol Police did deploy lethal force on Jan. 6 — shooting and killing 35-year-old Ashli Babbit — but have faced questions over why officers appeared to be less forceful against pro-Trump rioters than participants in previous demonstrations, including those over Black Lives Matter and now-Supreme Court Justice Brett Kavanaugh.

United CEO is confident people will feel safe traveling again by 2022

United Airlines CEO Scott Kirby believes that people will feel safe traveling again by this time next year, depending on the pace of vaccinations and the government's ongoing response to the pandemic, he said at an Axios virtual event.

Why it matters: Misery for global aviation is likely to continue and hold back a broader economic recovery if nothing changes, especially with new restrictions on international border crossings. U.S. airlines carried about 60% fewer passengers in 2020 compared with 2019.
