Air India said that regulators in India have grounded Boeing's 787 Dreamliners, too

After a series of issues with Boeing's 787 Dreamliner over the last week (including today), Japan decided to gound the planes until further notice. Now, the Federal Aviation Administration (FAA) has announced that all 787s will be grounded in the U.S. as well.

The FAA made this decision today after a 787, which was an All Nippon Airways (ANA) flight to Tokyo, had an issue with its main battery only 15 minutes into a 90-minute flight. After 40 minutes, a burning smell made its way into the cabin and cockpit, and the plane made an emergency landing at Takamatsu Airport on the southern island of Shikoku. Thankfully, all passengers and staff evacuated safely.

"We are very sorry to have caused passengers and their family members so much concern," said ANA Senior Executive Vice President Osamu Shinobe.

Even later, Air India said that regulators in India have grounded Boeing's 787 Dreamliners, too.

"Boeing deeply regrets the impact that recent events have had on the operating schedules of our customers and the inconvenience to them and their passengers," said Jim McNerney, Boeing chairman, president and CEO.

Unfortunately, this wasn't the only incident that Boeing's 787 Dreamliner experienced lately. Early last week, a 787 operated by Japan Airlines had experienced an electrical fire at Boston's Logan International Airport after coming in from Tokyo. According to the National Transportation Safety Board, a battery in the auxiliary power unit suffered severe fire damage.

Just one day later, a Boeing 787 operated by the same airline at the same airport suffered a fuel leak. The fuel leak was discovered at 12:25 p.m. ET right after the 787 left the gate for a trip to Tokyo. The flight was cancelled, and the plane was towed back to the gate where passengers were instructed to exit and stay in the airport. No one was injured.

As it turns out, about 40 gallons of fuel had leaked from the 787. The plane ended up being delayed four hours before leaving for Tokyo.

On Friday of last week, two more issues occurred.
It was discovered that a 787 Dreamliner with All Nippon Airways (ANA), which had arrived at the Matsuyama airport in western Japan from Tokyo on Friday, developed a web-like crack in the cockpit window. The pilot found it about 70 minutes into the flight, but no one was injured. In a separate incident on Friday, but also with ANA, another 787 Dreamliner had an oil leak after traveling to the Miyazaki airport in southern Japan. It is unclear how much oil had leaked.

its a complex plane, manufactured and designed in a novel complex way.

they'll sort this out.

the a380 was a similarly complex project and had its uncontained engine explosion issue (also potentially very serious) which has been resolved.

Agreed. You can look at most airliners and see similar trends during the "growing pains" phase. I suspect that in 5 years or so, the 787 will be as reliable and trouble-free as the 707 was in its hey-day.

"Vince Weldon's experience in the use of composite materials led to him being asked by Boeing to research how advanced composites could be used to build its next generation passenger airliner, the 787 Dreamliner.[1] Weldon told Boeing management that the carbon fiber-reinforced plastic material which was being used to construct the Boeing 787 Dreamliner was unsafe, less safe than a conventional aluminium aircraft, and that in the event of a crash the composite fuselage would "shatter too easily and burn with toxic fumes".[7] Boeing fired Weldon in July 2006.[8]"

unrelated to the battery problems, but still worth reading.

So they do crach test them? Or is performance in crash based on theory?

Have they ever actually crash tested this plane? As far as I know they don't normally, but it would seem like a sensible thing to do especially when using new materials.

15 ft drop test (of a fuselage section).

Well that doesn't entirely tell the story

New aircraft are Statically and Fatigue Tested as well as interior things such as seat tracks, galleys, etc tested to near "crash" conditions.

The 15 foot drop test was a hard belly landing test specifically designed for the 787.

Most telling is that Boeing decided not to test the 787 wings to failure (as it had on previous models), in part due to safety concerns over composite dust.

Clearly composites are not safe on fracture in a controlled lab enviroment, why would they be safe in an actually accident.

Offsetting this is the massive amount of deflection required to actually fracture composites. If I am in a plane that hit the ground with enough force to shatter the composites...

Don't think that's correct.

787 wing test to failure (which happened at 150% of design limit):

Hah, that's not a real wing break test.

That's a very small part of the wing being tested to failure. Lots of the parts/components were tested to failure

This is a wing failure test. Done full scale. Notice all the people watching in the same building? Notice that you don't see the same thing on the component failure test?

Actually, that IS the whole wing. The FAA and other authorities world wide would not accept the test validation without a whole wing test. Further, the test can not be done with a prototype wing it must be a "ready for production" unit.

Were there any major issues with the 777 the first few years after it was introduced ? I don't remember any.

The 777 didn't have all of the technological changes that the 787 has, so it was more an evolution of prior models.

The Trent engines on the 777 did have issues although I'm not sure if you'd call that a problem with the airplane.

I'll second that. And this is not a problem with the aircraft structure, but rather it's batteries. The batteries in question are made by a contractor. Boeing is taking a great deal of flak for a problem they are not fully in control of. However, grounding the aircraft world wide was a recommendation made by Boeing themselves to the FAA and other authorities. This, to me, seems like the act of a company that is taking safety seriously. Grounding the aircraft is the right thing to do until the fire hazard can be solved. I personally applaud the actions taken. These issues will solved and the aircraft will be cleared to fly again.

Every aircraft ever to fly has had growing pains and problems to be worked out. This kind of thing is not new. But public over-reactionism can be a real problem. So folks how about you all keep a cool head and let the experts work the problem, eh? I speak to the hot-heads making irrational posts.

The A380 has had 2 incidents which were both caused by there engines, which is NOT an Airbus issue but an engine manufacturer issue in this case Rolls-Royce.

These are issues that should have been addressed during construction, quality testing and design, and should not be in a production aircraft. This is simply sloppy quick work to get it to customers. Airbus spend two years to address cable issues. In fact, in the industry these are one of the most experienced issues in complex machinery that should be fixed before delivery.

Besides, electric wiring problems have been going on for months and Qatar Airways had grounded their 787 since December. The recent Japanese accident were only the first serious events.

Once again, the BATTERIES are made by a contractor. Your "sloppy" comment would be like blaming Ford for fires caused by the batteries installed in them, or for crashes resulting from failed tires put on the wheels. Boeing is being blamed for something beyond their complete control.

HOWEVER, they are being responsible and working the problem. I wouldn't want to be the maker of those batteries at this moment...
