April 9th, local time, Boeing issued a statement saying that it had made suggestions to 16 customers to solve potential electrical problems before some 737 MAX passenger planes continued to operate. The statement said that the proposal was made to verify that a power system component has sufficient grounding paths.
Boeing is cooperating with the Federal Aviation Administration (FAA) in response to this issue, the statement said. Boeing notified customers of the affected aircraft number and will provide guidance on corrective measures.
It is understood that this “potential problem” was discovered by Boeing from an aircraft still on the production line. Boeing did not mention the specific customers of the problem aircraft in the statement.
Boeing 737 MAX suffered two major air crashes in October 2018 and March 2019, killing a total of 346 people. Since March 2019, many countries and regions around the world have announced that they have stopped or banned the 737 MAX series of passenger planes. At the end of 2020, civil aviation agencies, including the United States, Brazil, the European Union and other civil aviation agencies, have successively agreed to fly the aircraft again.
