TOKYO--Boeing Co. (BA) said Thursday it will explain its proposed package of fixes for the batteries on its 787 Dreamliner in Tokyo on Friday, the first time company executives will openly discuss details of safety enhancements they hope will enable airlines to resume worldwide commercial service using the aircraft.

Raymond Conner, CEO of Boeing Commercial Airplanes, and Mike Sinnett, head of Boeing's 787 program, will speak Friday morning to "provide details on the proposed permanent solution to the 787 battery issue." The solution aims to prevent possible overheating and fires in the 787's lithium-ion batteries.

Boeing said the 90-minute briefing will also be broadcast as a live webcast from 10 a.m. local time (0100 GMT).

The briefing comes the same week Boeing received initial approval from the U.S. Federal Aviation Administration for its proposed set of fixes. The decision came as welcome news for the Chicago-based plane maker as it seeks to end the two-month-long grounding of its flagship jetliner.

The FAA described the decision as "the first step in the process to evaluate the 787's return to" commercial service. Boeing now has the green light to start test flights as well as "extensive" additional safety analysis of the new safety measures.

Two separate incidents involving overheated and burned lithium-ion batteries installed on two Dreamliners in January sparked a worldwide grounding of the jet. High-profile investigations in the U.S. and Japan--where the two incidents occurred--have made frustratingly little progress in identifying the root cause.

Boeing's decision to hold the event in Tokyo over its home base in the U.S. indicates the importance of keeping two of the 787's biggest customers happy. Japan Airlines Co. (9201.TO) and All Nippon Airways Co. (9202.TO) together own nearly half of the 50 jets that were in service before the grounding. Both battery incidents also took place on 787s operated by the Japanese carriers.

The Boeing executives came to Tokyo in late February to relay its proposed "permanent solution" to Japan's transport minister, regulators and the two airlines.
