Boeing’s 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 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.
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 Airport after a battery in an auxiliary power system explodes.
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.
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.
January 11 – The 787 will undergo a comprehensive review of its critical systems by regulators, the US Department of Transportation says.
