ANA 787 grounded for inspection after being hit by lightning

http://flyteam.jp/news/article/5417

Sorry only in Japanese. It was performing the KIX-OKJ training on Oct 22 and got hit by lightning. It was then grounded at OKJ for inspection. ANA resumed training flights after inspection is completed the next day.

Poor thing...first it's the boarding bridge, now it's lightning Hopefully it doesn't take this long for inspection next time it's hit by lightning

wow... strange karma...

all the delays... then had to rework the wings... finally comes the first delivery to ANA...

then the poor baby hits a boarding bridge, gets a damaged engine cowl... and now this?



i hope all will go smoothly on the HKG flights!

good thing they did not decide on Frankfurt right out

Hey ANA you better take good care of Princess Dreamliner!

What happening there? Is that something wrong the 787? Did lightning got strikes the plane. I wasn't sure why has happening the 787. Do they have any damaged the plane? They have be more extremely careful out there.

They have resumed the training flights the next day so everything seems ok for now

No panic need you.

Unless planes avoid clouds of any type all together, there's no way to avoid lightening strikes, which happen quite frequently. Thankfully, they design planes to withstand even the powerful strikes. In most cases the plane would continue onward to its destination.

...But since it's a brand new design, it doesn't hurt to err on the side of caution.

I wonder how differently the carbon-fiber body reacts to lightning than a typical aluminum fuselage. I would guess that the all-aluminum cans would simply conduct the bolt via whatever path provides the least resistance to...where? Does the current continue past the airplane to the adjoining cloud with a different charge? Or is there a positive "sink" somewhere in the aircraft (can't imagine...that's a lot of power).

But with the 787, I would think there aren't as many readily-available paths for the current, and the resulting current density would be greater through portions of the 787 airframe than similar airframe components of the aluminum cans.

Or do I have no freaking clue what I'm talking about?

I've seen video of the lightening bolt going through a 747 and continue to go straight to the ground. But you raise an interesting question about carbon-fiber's ability to withstand direct strikes. Perhaps the paint is metallic or something. Its worth looking into.

Boeing Co.’s new composite-plastic 787 Dreamliner survived its first lightning strike with no damage as the plane approaches the halfway point in flight testing, program manager Scott Fancher said.

The jet was flying last month above Puget Sound, near Seattle’s Boeing Field, when it was hit unexpectedly by a lightning bolt during a rare thunderstorm in the area, Fancher said yesterday in a telephone interview. The aircraft’s systems, fuselage and wings all appeared to be unscathed, he said.

Local Seattle media report she's now suffered a landing gear system failure too.
