There have been a number of developments within the past two hours on the Boeing 787 situation. Unfortunately, the key articles are from The Wall Street Journal (subscription required).
- Boeing has a series of design changes it is proposing to the FAA to serve as an interim fix to mitigate fire risk until a permanent solution is found. The WSJ reports that these include spacing the battery cells; adding some rigidity to prevent shifting from vibrations and interfering with electronics; eventually shifting to a new battery altogether; fire containment; and more.
- The WSJ reports that the FAA also wants longer warning times to alert the crew to any problems.
- The paper reports the FAA was still weighing approving a test flight; we heard on the radio after the WSJ posting that this has been done.
- The paper says Boeing hopes to be able to ship new batteries to airlines with grounded airplanes by the end of this month. This might mean flight resumptions in March.
- Moisture protection is also an element of the interim fix.
The WSJ also reported that the NTSB is examining the FAA’s approval and testing process, but we don’t consider this to be particularly new news.
The NTSB has a briefing Thursday at 11am EST. We’ll doing live updates on this blog.
