A probe has been launched into a landing gear problem with the first of two Boeing 787 Dreamliners delivered to All Nippon Airways less than two weeks ago.
Pilots were forced to deploy the landing gear using a manual backup system after an indicator lamp suggested the wheels were not properly down.
The aircraft landed at Okayama at the second attempt following the incident on Sunday, the airline said.
“We are not yet sure what the problem was, but we are investigating,” an ANA spokesman said, adding that Boeing is also involved in the investigation.
A Boeing spokesman said: “We are aware of this matter and are on site in Japan with ANA offering whatever assistance they require.”
The incident comes days after a Boeing 767 landed on its belly in Warsaw after the landing gear failed to deploy. ANA plans to fly the new generation lightweight aircraft on domestic routes in Japan on a trial basis before putting it on long international routes.
