Excerpted from the NY Times article supra,
All Nippon Airlines of Japan reported cracks in the cockpit window of a 787 Dreamliner heading from Tokyo to Matsuyama, the third time that cracks had appeared in the windshield of one of the 17 787s operated by the airline.
The cracks were on the outermost of five layers that compose the cockpit windshield and did not endanger the aircraft, said Megumi Tezuka, a company spokeswoman.
Moreover, she said, cracks of this kind are not unique to the 787 Dreamliner; cracks have appeared in other aircraft types operated by All Nippon from time to time.
In a separate matter, Japan Airlines said that an incident on Tuesday involving a fuel leak on a 787 was because one of four fuel valves connecting two tanks had been left open. This caused fuel to flow into a surge tank near the wing tip and out a vent. The plane was towed back to its gate but eventually left Boston for Tokyo after a delay of nearly four hours.
