Norwegian has put its second delivered Boeing 787 back into operation after technical problems led the twinjet to be taken out of service for some 12 days.
Chief executive Bjørn Kjos says that "small items" were enough for the airline to put the aircraft on the ground so that passengers would not be subjected to delays.
He stresses that work required under service bulletins was a factor in the duration of the grounding, along with the need to address "discrepancies". The airline had previously delayed the introduction of the aircraft (EI-LNB) after identifying "malfunctioning brakes" as a problem.
When the latest issues arose, Norwegian enlisted Boeing to fix them, The airline is enrolled in the airframer's GoldCare maintenance programme.
Kjos says 15 Boeing technicians worked "nose to tail" on the aircraft.
Norwegian's other Dreamliner (EI-LNA), delivered in June, has performed "wonderfully" in service within the low-cost carrier's newly launched long-haul network, says Kjos.
A third 787 is to be delivered to Norwegian on 20 November, and a fourth in January 2014.
In total, four Dreamliners are to be handed over to the Oslo-based airline over the full course of 2014, and its eighth is due by the end of the first quarter of 2015.
On the subject of compensation for in-service problems Norwegian has encountered with the type, Kjos says the costs caused by the disruptions are not yet known, and discussions with Boeing are ongoing. However, the airline has "good relations" with the airframer, he emphasises.
