Just read that the FAA is grounding the 787 fleet until fire problems with onboard batteries can be resolved.

It should be resolved by taking lithium ion batteries out of the aircraft :lol:

Not that easy, this aircraft does not use bleed air for engine start, it is almost wholly dependant on electrics. They chose Lithiun batteries because they are the lightest and most powerful, but alas, they are also the most unstable.

 

Replacing them will need a redesign, I don't think adding cooling will suffice, and I don't think Boeing will appease the FAA by simply providing statistics that point to low probability of a fire, they will need to do some hard core re-designing here.

 

Kudos to the FAA for taking action now and giving the manufacturer the breathing space to actually fix the battery issue, hope they also solve the fuel leaks while they are at it.

I agree--great for the FAA to act now. Does such a grounding also apply to the 787's in use in other countries?

Kudos for being the last governing agency to do so? The FAA is wholly reactionary and does very little to be proactive.

It is figure-of-speech. Better the administrator get in now before we have true costly accidents.

With JAL and ANA fleet grounded, do they get some sort of reimbursement for these circumstances for the lost revenue? This is not one aircraft, this is their whole fleet of brand new aircraft. That is alot of cancelled flights even though they can juggle aircraft. They must be irate to say the least.

I guess this of course affects other customers.

Depends what the commercial terms are. For entry to service there would be allowances Boeing would have made, such as Boeing technicians on site for a period of time, etc.

 

Grounding an entire fleet is a whole different matter, and I guess there would be some fast and furious phone calls to Seattle as we speak.

AFAIK the FAA were the first to mandate a grounding, although ANA and JAL had already voluntarily grounded their fleets, EASA followed FAA one or two days later. I'm not sure whether the Lan, Qatar and Ethiopian groundings are voluntary or not.

In principle the FAA only has a mandate over aircraft registered in the US, and, to a lesser extent, aircraft operated into, out of, or over the US. This means that the FAA grounding doesn't mean LOT (or JAL, ANA, etc) can't fly their 787s, although they may be prohibited from flying them into or out of the US (not sure how that works). In practise though if one of the two big regulators (FAA or EASA) announce something like an emergency grounding it would be very unusual for regulators in other countries not to follow suit. Indeed in this case EASA ordered a grounding within a day or two of the FAA order.

LOT's lot was to be caught on the ground here in the U.S., so until inspected and released, it's lot will be to remain here racking up ground fees...

 

...and there's not a lot LOT can do except grin and bear it.

I can't tell if you were trying to make a tongue twister or if you just happened to use the word lot so many times by accident.
