Just a month after its historic first flight, United Airlines' brand-new 787 Dreamliner was forced to make an emergency landing due to a mechanical issue. United flight 1146 from Houston to Newark was diverted to New Orleans on Tuesday for an unspecified mechanical problem. Emergency personnel greeted the plane, that carried 174 passengers and 10 crew members, in Louisiana but there were no reports of injuries.

Will be interesting to see just what the cause of this is. And to see if there is any long term issues that may lead to modifications to future aircraft that are produced similar to those suffered by the A380?

They've had quite a few mechanical issues so far. Several engine issues that prompted replacement of some parts on various engines. They're just teething problems, like the A380 had, and every new plane will have. The A350 will have them, and so will everything else.

ANA had a delay to one of the first flights, and then within about 10 flights had one have to divert. Nothing major, a hydraulic issue for one, and I'm not sure they ever said what the other one was caused by. This is mostly media hype since it's a new plane and uses so much new technology.

What's new about it? Hyd system seems to be relatively run of the mill. Avionics aren't what I would call new...And airlines have had MFDs for years.

I understand that they do offer certain amenities to the passengers onboard but I'm not sure what new technology could be added to this airframe.

It's 50% composite among other things.

Well ok. Composite material vs aluminum is new as far as commercial aviation is concerned. But at the same time I've seen lot of things touted as new in the aviation world even though the tech and its applications have been in use for over a decade. Like carbon fiber composite skin, or more close to home, UH60M folding stabilators that the Army is using now...Navy's H60s have been using them forever.

"Among 787 flight systems, the most notable contribution to efficiency is the new electrical architecture, which replaces bleed air and hydraulic power sources with electrically powered compressors and pumps, as well as completely eliminating pneumatics and hydraulics from some subsystems (e.g., engine starters or brakes)

To do this 787 uses an electrical system that is a hybrid voltage system consisting of the following voltage types: 235 volts alternating current (VAC), 115 VAC, 28 volts direct current (VDC), and ±270 VDC."

Thats pretty unusual for a large commercial airliner.

Composite skin, new electrical architecture, digital instead of analog systems, new pressurization methods, none of which had been done on any aircraft that size.

Fuel leaks have prompted FAA mandated inspection:


The Federal Aviation Administration is ordering airlines to inspect 787 Dreamliners for improperly installed fuel-line connectors that could result in leaks or even fires.

The safety directive, to be published Wednesday, gives airlines a week to check fuel-line system fastening wires and 21 days to check connectors inside the pylons that hold the engines.

Fuel leaks were reported by airlines on two in-service 787s, and subsequent inspections by Boeing of jets in service or still in production revealed some fuel line connectors were installed incorrectly.


as has been said - every new aircraft has its share of issues.

Heck even old ones do - AD's are still coming out for 737-100's and none of those are still flying!!!!

They had a power panel failure, that led to nuisance generator alarms on one of their six generators. They replaced the panel, and the plane is back in service.

Qatar Airlines third Dreamliner had a similar problem on its delivery flight, but it's too early to tell if it's the same problem, or if it's a different problem.

Unsure if this is aircraft related or something in the cargo? dreamliner caught fire at Logan airport in Boston.

It appears that it was an Auxiliary Power Unit battery that exploded. The APU provides power on the ground. The earlier problem was a generator that provides power in flight, which is mounted in the engine.

Thanks though, there's a thread in aviation about the fire now.
