TOKYO (AP) -- Japan's All Nippon Airways has reported two new cases of problems with its Boeing 787 Dreamliners.
ANA spokeswoman Ayumi Kunimatsu said Friday a very small amount of oil was discovered leaking from the left engine of a 787 flight from southern Japan's Miyazaki airport to Tokyo. The jet returned to Miyazaki, but after checks found no safety risk it flew to Tokyo.
ANA said on another flight, to Matsuyama on Shikoku island, glass in a cockpit window cracked and the aircraft was grounded for repairs.
The airline cancelled a domestic flight to Tokyo on Wednesday after a computer wrongly indicated a problem with the 787's brakes.
Boeing has insisted that problems with the 787 are no worse than what it experienced when its 777 was new in the mid-1990s.
