Airlines pulled dozens of Boeing Max 737s out of service for inspections, for the second time. It was requested by the aircraft maker. Discussions are about a possible electrical problem which was discovered on a plane on the production line. Boeing said the new issue, in which a component in the electrical power system might not be correctly grounded, was unrelated to the flight-control system. Boeing said Friday that the issue affected planes used by 16 airlines but did not say how many planes are affected. Southwest Airlines, which began flying the Max again last month, said it removed 30 of its 58 Max jets from its schedule to inspect them. American Airlines temporarily removed 17 of its 41 Max planes from service. United Airlines said it temporarily grounded 16 of its 30 Max planes. Alaska Airlines said it removed all four of its Max jets from service.
Boeing said it is working with the US Federal Aviation Administration to address the problem. The newly discovered issue could undermine efforts by Boeing and airlines to restore passenger confidence in the plane. Shares of Boeing Co., based in Chicago, fell about 1% in afternoon trading.
