The big news in the last week is that the FAA has approved the recertification process that Boeing has proposed for the Li-ion batteries in the 787. From their press release:
The certification plan is the first step in the process to evaluate the 787’s return to flight and requires Boeing to conduct extensive testing and analysis to demonstrate compliance with the applicable safety regulations and special conditions.
The important thing to understand is that the 787 is NOT cleared for flight. Nor has Boeing’s proposed fix been cleared for implementation. The FAA has approved a series of tests that Boeing must perform, and the Li-ion batteries must pass, to prove the proposed fix works properly.
There’s still a long road ahead of Boeing on this issue.
