Japan's two main airlines have grounded their Boeing 787 Dreamliners after one was forced to make an emergency landing because of battery problems.
All Nippon Airways (ANA) grounded its fleet of 17 Dreamliners when its flight NH 692 from Yamaguchi Ube was forced to land shortly after take-off.
Japan Airlines followed suit, saying it would ground its fleet of seven 787s from 16 January until further notice.
This is the latest setback for Boeing and its problem-hit Dreamliner planes.
Shares in Boeing fell more than 3% at the start of trading in New York following the Japanese announcements on Wednesday.
In recent weeks, Dreamliners have suffered issues including fuel leaks, a cracked cockpit window, brake problems and an electrical fire.
On Wednesday, ANA's flight NH 692 left Yamaguchi Ube in western Japan at 08:10 local time (23:10 GMT) and headed for Tokyo's Haneda airport.
Earlier reports that smoke was seen in the cockpit were inaccurate, ANA said. The pilots saw a warning on their computer screen telling them there was smoke inside one of the electrical compartments, the airline said. The source of the smoke is not yet known.
The pilots also received a warning that there was a fault in the battery system. ANA said the battery in the forward cargo hold was the same type as the one involved in a fire on another Dreamliner at a US airport last week.
The ANA flight landed at Takamatsu airport at 08:47 on Wednesday after the pilot saw an error message in the cockpit.
"There was a battery alert in the cockpit and there was an odd smell detected in the cockpit and cabin, and [the pilot] decided to make an emergency landing," said Osamu Shinobe, an ANA vice president, at a news conference.
ANA said that the 129 passengers and eight crew were evacuated, with a number of people sustaining minor injuries.
