The National Transportation Safety Board is ready to release its early findings about a battery fire that broke out in January on a Japan Airlines Boeing 787 Dreamliner, according to a media report.

The federal agency said it will issue an “interim factual report” at 11 a.m. Thursday, according to Reuters news service.

The board said the information to be released on the Jan. 7 incident at Boston Logan International Airport was “factual in nature and does not provide any analysis,” Reuters reported.

No one was hurt in the fire. Boeing has been trying to determine the root cause. It has submitted a permanent but undisclosed fix to the Federal Aviation Administration.

All 787s worldwide are grounded.

The passenger jets are made in North Charleston and Everett, Wash.
