Japan Airlines Co. today conducted its first test flight of the Boeing 787 Dreamliner jet since the aircraft was grounded worldwide due to battery troubles in January.
All Nippon Airways Co., another Japanese carrier with a Dreamliner fleet, started test flight of the fuel-efficient airplane earlier in the week following the US regulators’ approval of Boeing’s modified battery system, aiming to resume commercial flights in June.
Japan Airlines, commonly known as JAL, said its Dreamliner took off from Haneda airport in Tokyo early today for a two-hour flight over the north-eastern region to check a modified battery system,
JAL, which owns seven 787s, also plans to resume the jet’s commercial service in June after confirming the safety of the new battery system in test flights.
The airline will conduct a test flight using another 787 aircraft later in the day at Narita airport near Tokyo.
