Boeing Face to Face with one more penalty

Boeing engineers discovered in 2017 that a software glitch had rendered a warning light on the newly introduced 737 Max inoperable on 80% of the planes. But the company chose not to fix it or to inform U.S. regulators.

Now the inoperable warning light is threatening to become a costly new headache for the planemaker: its absence on the jet violated U.S. Federal Aviation Administration regulations.

The FAA is considering imposing civil penalties, according to documents and officials, which can amount to millions of dollars.
