Boeing has told the Federal Aviation Administration that more than 300 of its 737 jets — including the grounded 737 Max aircraft — may contain faulty parts on the wing, the FAA announced in a statement Sunday.

[W]e have determined that up to 148 parts manufactured by a Boeing sub-tier supplier are affected. ... The affected parts may be susceptible to premature failure or cracks resulting from the improper manufacturing process. "
— FAA statement

Details: Boeing identified issues with slat tracks, which are located at the front of a plane's wing. They play a vital role during take-off and landing. In the U.S., suspect parts were found in 33 of Boeing's 737 Max jets and 32 of its 737NG aircraft. "Affected worldwide fleet are 133 NG and 179 MAX aircraft," the FAA said.

"Although a complete failure of a leading edge slat track would not result in the loss of the aircraft, a risk remains that a failed part could lead to aircraft damage in fight."

What they're saying: Boeing said in a statement it had identified 21 of its 737NGs to most likely feature the faulty parts. "Boeing identified 20 737 MAX airplanes that are most likely to have the parts in question," it said.

Why it matters: This is the latest issue to hit the world’s largest aerospace company since its 737 Max series was grounded after the Ethiopian Airlines crash outside Addis Ababa in March, which killed 346 people, following a deadly October crash near Jakarta, involving a 737 Max operated by Lion Air.

  • In March, Boeing found flaws in its flight simulators that were used to train pilots.

Tech scrambles to derail inauguration threats

Tech companies are sharing more information with law enforcement in a frantic effort to prevent violence around the inauguration, after the government was caught flat-footed by the Capitol siege.

Between the lines: Tech knows it will be held accountable for any further violence that turns out to have been planned online if it doesn't act to stop it.

Uganda's election: Museveni declared winner, Wine claims fraud

Yoweri Museveni was declared the winner of a sixth presidential term on Saturday, with official results giving him 59% to 35% for Bobi Wine, the singer-turned-opposition leader.

Why it matters: This announcement was predictable, as the election was neither free nor fair and Museveni had no intention of surrendering power after 35 years. But Wine — who posed a strong challenged to Museveni, particularly in urban areas, and was beaten and arrested during the campaign — has said he will present evidence of fraud. The big question is whether he will mobilize mass resistance in the streets.

Off the Rails

Episode 1: A premeditated lie lit the fire

Beginning on election night 2020 and continuing through his final days in office, Donald Trump unraveled and dragged America with him, to the point that his followers sacked the U.S. Capitol with two weeks left in his term. Axios takes you inside the collapse of a president with a special series.

Episode 1: Trump’s refusal to believe the election results was premeditated. He had heard about the “red mirage” — the likelihood that early vote counts would tip more Republican than the final tallies — and he decided to exploit it.

"Jared, you call the Murdochs! Jason, you call Sammon and Hemmer!”
