Boeing Co's new 787 Dreamliner is the pride of the company's passenger jet fleet, but a series of incidents in the last few months have raised questions about its safety and image. Following is a list of the events:
July - A General Electric Co engine on a 787 in North Charleston, South Carolina, breaks during a preflight test. The National Transportation Safety Board rules it a "contained" failure, meaning the broken pieces did not exit through the engine wall. GE orders inspections of the engines. The Federal Aviation Administration stops short of grounding planes for inspections.
December 4 - A United Airlines 787 with 184 people aboard is forced to make an emergency landing in New Orleans after experiencing electrical problems.
December 5 - U.S. regulators say there is a manufacturing fault in 787 fuel lines and advises operators to make extra inspections to guard against engine failures.
December 13 - Qatar Airways grounds one of its three 787s after finding the same electrical problem that affected the December 4 United flight.
December 17 - United confirms finding an electrical problem in a second plane in its 787 fleet.
January 7 - A parked 787 operated by Japan Airlines catches fire at Boston Logan International Airport after a battery in an auxiliary power system explodes.
January 8 - A second 787 operated by Japan Airlines leaks fuel at Logan, forcing it to cancel its takeoff and return to the gate. The plane departs later.
Following a safety inspection, United finds a wiring problem in the same electrical system that caused the January 7 fire in Boston, the Wall Street Journal reports.
January 9 - Japan's All Nippon Airways Co cancels a 787 flight scheduled for a domestic trip within Japan due to brake problems.
January 11 - A cockpit window on an ANA 787 cracks during a Japanese domestic flight. The plane lands safely with no injuries.
A separate ANA 787 springs an oil leak from its left engine, which is discovered after the plane lands safely.
The U.S. Department of Transportation says the 787 will undergo a comprehensive review of its critical systems.
January 13 - The Japan Airlines 787 that leaked fuel in Boston on January 8 experiences another, separate fuel leak while undergoing checks in Tokyo.
January 15 - A 787 operated by ANA makes an emergency landing at Takamatsu in western Japan after smoke appears in the plane's cockpit.
