Boeing's 737 Max plane, which was previously involved in two fatal crashes, has another issue affecting more than 100 aircraft worldwide.

The company first said on April 9 that some of the planes were facing "a potential electrical issue" and recommended that 16 airlines immediately ground their affected models so the issue could be resolved. At the time, few other details were released.

On April 22, the Federal Aviation Administration gave notice to international air regulators about the problem and said 106 airplanes were affected, 71 of which were registered in the US, Reuters reported.

"We are working closely with the US Federal Aviation Administration on this production issue," Boeing said. "We are also informing our customers of specific tail numbers affected and we will provide direction on appropriate corrective actions."

Boeing and the FAA did not specify which airlines were affected, but Southwest Airlines, United, and American Airlines confirmed separately that they were pulling affected planes from operation. Southwest said 30 of its planes were affected. For American, it was 17, and 16 for United, the companies said.

Boeing's 737 has been in production since the late '60s, but the most recent model - the 737 Max - has been problem-riddled. It was involved in two fatal crashes, with 346 fatalities, and was grounded worldwide for more than a year as Boeing worked with the FAA and international regulators to sort out the plane's issues.

It was recertified for flight in late 2020, and Boeing recently began delivering new models to waiting customers.
