Boeing Co's sophisticated new aircraft, the 787 Dreamliner, will undergo a comprehensive review of its critical systems by regulators, the U.S. Department of Transportation said on Friday after a series of problems in recent weeks.
The review of the jet will include design, manufacture and assembly, including a battery that caught fire on an empty 787 parked in Boston on Monday.

Adding to the tally of incidents that have tested confidence in the Dreamliner, on Friday the passenger jet suffered a cracked cockpit window and an oil leak on separate flights in Japan.
The U.S. Department of Transportation said it plans to announce more details of the review at a press conference Friday at 9:30 am ET (1430 GMT).
In Japan, All Nippon Airways Co said a domestic flight from Tokyo landed safely at Matsuyama airport in western Japan after a crack developed on the cockpit windscreen, and the plane's return to Tokyo was canceled.
The same airline later said oil was found leaking from an engine of a 787 Dreamliner after the plane landed at Miyazaki airport in southern Japan. An airline spokeswoman said it later returned to Tokyo after some delay. No one was injured in either incident.
