After a week of 787 Dreamliner service interruptions in Norway, Boeing said Monday that power supply glitches on two separate 787s operated by Norwegian Air Shuttle have been resolved and both aircraft are now back in passenger service.

The Norwegian low-cost carrier has two 787s, and has six more on order. A week ago, the first was grounded for five days after a power supply issue to the electric brake system showed up during routine maintenance on the ground

Five days later, that was fixed, but on Saturday the carrier’s second 787 developed an apparently unrelated power supply problem, this time connected to the jet’s central computing system.

In a statement, a Boeing spokesman said the company is “committed to improving the 787’s in-service dispatch reliability …(with) a significant focus on component reliability improvements.”

The 787 fleet is averaging about 175 revenue flights per day around the world and has flown more than 12,000 revenue flights since the grounding of the fleet was lifted in April following implementation of a fix for an earlier battery problem.
