Flight 7 landed as a “precautionary” measure at Logan International Airport where Japan Airlines’ mechanics are examining it for any possible damage, Carol Anderson, a spokeswoman for the carrier, said in a telephone interview. She added that 184 passengers and 12 crew members were on board.
The pilots didn’t declare an emergency and the plane landed safely after dumping fuel, Lynn Lunsford, a spokesman for the U.S. Federal Aviation Administration, said in an e-mail.
The incident came hours after investigators focused on a beacon made by Honeywell International Inc. as being linked to the July 12 Dreamliner fire at London’s Heathrow airport. That eased investor concern that the U.K. probe would raise new questions about the electrical system whose battery meltdowns spurred a global 787 grounding this year.
Boeing rallied 2.7 percent at the New York close on news of the U.K. inquiry’s preliminary report, then fell 1.3 percent to $106.25 at 7:59 p.m. in extended trading as word spread of Flight 7’s diversion.
The flight departed Logan at 1:19 p.m. local time and was scheduled to last more than 13 hours before the twin-engine 787 returned at 6:16 p.m., according to industry data tracker FlightAware.com.
