Chile's LAN has completed a test flight of its Boeing 787 with the airframer's improved battery solution, and expects to resume revenue service in "the coming days".
The carrier, part of the LATAM Airlines Group, conducted the nearly 2h test flight over Santiago.
LAN's three 787s have been grounded since January, when the US Federal Aviation Administration (FAA) issued an order to ground the type following incidents involving the 787's lithium-ion batteries. The FAA lifted the grounding in late April, after it cleared Boeing's proposed battery design for the aircraft.
LAN says it worked with 30 Boeing technicians to implement the changes to the 787s' battery systems.
"The operation of the aircraft was completely normal. We have complied with all of the required modifications of the Dirección General de Aeronáutica de Chile (DGAC) and the FAA, and have implemented the modifications alongside Boeing technicians. This aircraft is one of the most modern in the world, and we are confident that it will significantly improve the flying experience of passengers that fly with LAN," says LAN's chief executive Ignacio Cueto.
The airline says it will "resume 787 operations in the coming days" without elaborating on the timeline.
LAN says it has not experienced any battery incidents when it operated its 787s to Buenos Aires, Lima and Los Angeles from Santiago before the grounding took place.
