The news agency, Reuters, has listed the various events that have cast doubt on the Boeing 787 Dreamliner’s safety levels. 2012 July - A General Electric engine on a 787 in North Charleston, South Carolina, breaks up during a pre-flight 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 - US regulators say there is a manufacturing fault in 787 fuel lines and advises operators to make extra inspections to guard against engine failures.

January 8 - A second 787 operated by Japan Airlines leaks fuel at Boston, 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 cancels a 787 flight scheduled for a domestic trip within Japan due to brake problems.
