From the FAA:
The Federal Aviation Administration (FAA) today approved the Boeing Commercial Airplane Company’s certification plan for the redesigned 787 battery system, after thoroughly reviewing Boeing’s proposed modifications and the company’s plan to demonstrate that the system will meet FAA requirements. 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.
“This comprehensive series of tests will show us whether the proposed battery improvements will work as designed,” said Transportation Secretary Ray LaHood. “We won’t allow the plane to return to service unless we’re satisfied that the new design ensures the safety of the aircraft and its passengers.”
The battery system improvements include a redesign of the internal battery components to minimize initiation of a short circuit within the battery, better insulation of the cells and the addition of a new containment and venting system.
“We are confident the plan we approved today includes all the right elements to conduct a comprehensive evaluation of the battery system redesign,” said FAA Administrator Michael P. Huerta. “Today’s announcement starts a testing process which will demonstrate whether the proposed fix will work as designed.”
The certification plan requires a series of tests which must be passed before the 787 could return to service. The plan establishes specific pass/fail criteria, defines the parameters that should be measured, prescribes the test methodology and specifies the test setup and design. FAA engineers will be present for the testing and will be closely involved in all aspects of the process.
The FAA also has approved limited test flights for two aircraft. These aircraft will have the prototype versions of the new containment system installed. The purpose of the flight tests will be to validate the aircraft instrumentation for the battery and battery enclosure testing in addition to product improvements for other systems.
The FAA will approve the redesign only if the company successfully completes all required tests and analysis to demonstrate the new design complies with FAA requirements. The FAA’s January 16, 2013 airworthiness directive, which required operators to temporarily cease 787 operations, is still in effect, and the FAA is continuing its comprehensive review of the 787 design, production and manufacturing process.

Tanker-like Redux: As you read this story, it sounds a lot like Boeing vs EADS, right down to the build-it-in-the-USA element.
Ryanair’s 200 737s: News emerged that Ryanair will firm up an order soon for 200 Boeing 737s. This has been hanging “out there” for some time. We learned of this likelihood a couple of months ago. It was all hush-hush while Ryanair took another run at Aer Lingus.
Pan Am landmark: For those filled with nostalgia, this news is sad: the famed Pan Am Worldport faces the wrecking ball.

777X ATO: Aviation Week reports that Boeing’s Board will grant Authority to Offer the 777X at the next meeting, in April.
Emirates Airlines has previously said it will order 100 or more of the X to begin replacing its 777-300ERs. Lufthansa and Air Lease Corp are likely co-launch customers.
Update: The Wall Street Journal now has an article identifying British Airways and Japan Air Lines as possible launch customers.
787 and the FAA: The FAA is expected to green light this week going forward with Boeing’s proposed fixes for the battery issues in the 787, but this doesn’t mean the challenges are over for Boeing. Extensive lab and flight testing will be required, meaning it still will be some time before the grounding is lifted.
A318 Done: Bloomberg has a story about the Airbus A318 and its dried-up sales. It was never a good seller.

The National Transportation Safety Board (NTSB) notes that the information discussed in this interim factual report is based on initial findings from the investigation of this incident. Because the investigation is continuing , no conclusions or recommendations are being made at this time. Readers are encouraged to access the public docket for this incident (DCA13IA037) for further details about the information presented in this report.
In addition, readers are advised that the information presented in this report could change if new evidence becomes available.
The Seattle Times reports the NTSB plans public hearings on lithium-ion battery safety.
Reuters reports that the NTSB has not found the root cause of the Japan Air Lines incident.

LOT wants $$, Norwegian Leases A340s: The fall-out gets worse over the 787 grounding. LOT Airlines says it wants compensation by the end of June. TUI is rebooking passengers on Boeing 767s and will refund a price differential for those paying a premium to fly the 787. Norwegian Air is wet-leasing Airbus A340s to fill in for the 787s it was supposed to get.
Aeroturbopower has an interesting analysis of the Norwegian lease cost of the A343 v 788, including some admittedly speculative costs to Boeing.
In other news:
We’ve been reading a lot of comments from our own readers and some from more qualified analysts or experts who are constantly criticizing the Boeing proposal to have a containment box for the lithium ion battery on the 787. The gist of the criticism is that this “super box” is a bad idea that doesn’t solve the problem.
While we’ve joked that the box is a fire place, we feel compelled to point out that the Boeing solution is similar to that adopted by Cessna. Readers forget The Seattle Times published this article January 29 describing the Cessna solution, which is pictured here.
This approach, according to The Times article, is well advanced through FAA review.
The aviation industry doesn’t work in a vacuum and clearly Boeing is aware of this approach.
For those enthusiasts and more qualified critics of the super box, keep the Cessna approach in mind.
