JAL finds fault on modified Dreamliner, say reports From:AFP June 03, 2013 8:12AM JAPAN Airlines found a fault with a modified Dreamliner yesterday, reports said, a day after it resumed full operation of Boeing's flagship 787 fleet following battery problems. JAL was forced to use another aircraft for a flight scheduled from Tokyo to Beijing after it found a fault with an air pressure sensor in the Dreamliner's battery container, Kyodo News and Jiji Press said. The incident comes only a day after JAL and All Nippon Airways, the single biggest operator of 787s, put their full fleet of Dreamliners back into service following a four-month suspension due to battery problems. ANA had started using Dreamliner planes for irregular flights last month. JAL said the pressure sensor of the battery container in the plane showed a difference in air pressure between inside and outside during a safety check before departure, according to the media reports.
