On March 15th, Boeing advised airlines to inspect the cockpit seats of their 787 aircraft in response to frequent aircraft accidents. The company also suggested that airlines check the cockpit seat switches when repairing the 787 aircraft and provided a guide on how to turn off the seat switch power. Boeing stated that this suggestion is only a preventive measure, but the Federal Aviation Administration of the United States stated that the suggestion is aimed at the accident that occurred on the Boeing 787 aircraft on the 11th, and they are convening an expert group to review Boeing's recommendation information.
