Narrowing the Cause: Aviation Week has a good article with some behind-the-scenes snippets about the grounding of the Boeing 787. Toward the end are comments from Japan Air Lines about narrowing the cause of the battery problems.
The JAL comments support what we heard on Friday: that Boeing and investigators are indeed beginning to focus on what they think may be behind the battery incidents. Things are still too fluid and uncertain to provide details here–we don’t want to head people or media off in the wrong direction, even inadvertently–but we’re cautiously optimistic.
Aviation Week also has this story about failure mode testing and the 787 batteries.
Reuters has this story about the progress being made in the investigation.
What this means for grounding: So the continuing question remains, how long will the 787 be on the ground? Boeing wants to get the airplanes in the air this month. A source, citing conversations he’s had with the FAA, says the federal agency sees the 787 grounded a minimum of 30 days and a maximum of 120.
Lithium-ion Batteries OK to Fly: The Detroit News has an interesting story: while the 787 is grounded, lithium-ion batteries are continued to allow to fly in cargo holds.
Air Lease Orders 25 A350s: This is the long-overdue order (it was expected last November). Included are 20 A350-900s and five A350-1000s.
