All Nippon Airways has admitted that its first Boeing 787 suffered some slight surface damage to its engine inlet cowl after it hit a passenger boarding bridge.
The incident took place while ground crew were towing the aircraft, JA801A, on 13 October, said the spokesman.
He added that the Rolls-Royce Trent 1000-powered aircraft suffered only surface damage, and that it resumed regular flight tests on 14 October after the company did some checks.
"Everything was fine. There was only some surface damage, and the aircraft was back in operation on schedule," said the spokesman.
The inaugural flight for the 787 is on track for 26 October. This will be a special charter service between Tokyo's Narita airport and Hong Kong.
Regular scheduled services start on 1 November, with daily flights between Tokyo's Haneda airport and the cities of Okayama and Hiroshima. International operations are due to begin in December on the Haneda-Beijing route.
The spokesman also said that ANA has received its second 787, which was delivered to the Japanese carrier on 16 October.
