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.

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.
