Japan Airlines Co. said it had to replace a Boeing Co. 787 with another plane after a sensor indicated a problem with the Dreamliner’s battery box.
Tape covering two holes used to regulate airflow in case of a battery fault in the auxiliary power unit was not removed after testing, triggering the alert, JAL said in a statement today. “The battery showed no abnormality,” it added.
The global 787 fleet has only just begun resuming operations after a battery flaw in January triggered a worldwide grounding that also halted new deliveries. Boeing had to modify the battery system to address safety concerns.
JAL replaced the Dreamliner to be used for Flight JL021 with a Boeing 767-300, incurring a 1 hour 5 minute delay in the process. The swap took place at Haneda airport in Tokyo.
The affected Dreamliner had flown twice the day before without incident, JAL said.
