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.

Just as they caused issues in laptops and EV's, lithium-ion batteries are causing issues for the 787 auxilary power generator system. Fix that and some other minor issues and the 787's will be pretty damn reliable considering all the tech upgrades. At least their wings don't crack at the fuselage like the A380's do...

The wing damage was progressive and noticed long before it could ever have caused any possible failure. Not good, but not dangerous either.

Over-heating batteries, or batteries catching fire without warning is a far more serious issue as it could knock out many systems without any previous warning.

Given the choice, I'd prefer to travel by train, but between those two planes, I'd choose the A380. That way I wouldn't be gambling against a fire-risk on every flight.

Really? I disagree most strongly! ANYONE who knows anything about metallurgy can tell you that under stress, ANY small crack can turn into a great big one very quickly. Such a thing is just as serious as the battery problem.

This is why the effected A380's were grounded until the repair could be made. Unlike the current 787 battery problem, the wing cracks were not present in all A380's and thus only the ones effected needed grounding. In this situation with the 787's, no one knows for sure which batteries are effected and safety being a primary concern grounding the fleet was the wise and responsible thing to do. Both Boeing and Airbus are working the problems in the correct way.

Do they?

News to me.

Now, cracks on the wing rib feet (which are in the wing and connect the ribs to the skin) have been observed.

Cracks at the wingbox would be a much bigger concern than some small cracks on a few rib feet.

Yes they do. Cracks on a piece of metal that deals with tension and torsion loads by design is a serious problem. No less serious than a fire hazard caused by faulty batteries.
