WASHINGTON (Reuters) - The U.S. National Transportation Safety Board said on Wednesday that investigative work on a battery fire aboard a Japan Airlines (9201.T: Quote) Boeing 787 Dreamliner jet in January 2013 would be completed by the end of March.

The agency gave no indications about the cause of the fire and said its final report on the incident at Boston Logan International Airport would be presented at a public meeting in Washington in the fall.

Members of the investigative team have been working for months in the United States, Japan, France, and Taiwan in their study of the Dreamliner battery and charging system.

Regulators grounded the global fleet of Boeing Co (BA.N: Quote) Dreamliners for 3-1/2 months after the January 7, 2013, incident at the Boston airport and a second battery incident on an All Nippon Airways (9202.T: Quote) flight in Japan several days later that prompted an emergency landing and evacuation.

The Boston fire was discovered by a mechanic who was performing a routine post-flight inspection and was the only person aboard at the time. Fire fighters responded and contained the blaze.

Crew aboard the ANA flight reported smelling smoke, but the incident was never officially ruled a fire.

The NTSB investigation only covers the Boston fire, though the U.S. agency has assisted Japan's Transport Safety Board with its investigation.

The Dreamliner, launched in 2004, offered saving fuel and maintenance costs through use of lightweight materials and new construction methods, including global outsourcing of its major components.

Assembly lags put the jet into service in 2011, more than three years behind schedule. And it has been plagued by problems, often involving its advanced electrical system.   Continued...
