Not the best way of giving a baptism to the newest toy in the fleet  http://www.flightglobal.com/news/art...t-787-into-boarding-bridge-363604/


Apparently the damage was very minor, but still, come on guys... be careful with this baby !!!

Oh boy. Not a good start. But these things can happen. Bad luck that it was the 787.

Will repairs to the fuselage be more expensive or complex now that they are using composites compared to aluminum?

I think yes, but will not happen as often as aliminum.

Depends . . .

If they decide to do a standard bolt-on repair, then the cost would be almost the same.
If they decide to do a "bonded" repair, then it could be more costly.

As far as this incident is concern, looks like the damage was to the engine cowl which would have been composite anyway whether the fuselage was aluminum or composite.

It's not like this aircraft is the biggest in the ANA fleet... It is only really slightly bigger than the 767!

When the A380 entered service there were a number of mishaps, which although avoidable were slightly more understandable due to the aircraft's size and dimensions.

Did ANA put its most inexperienced ground crew in charge of towing this expensive piece of gear around?



Next Flights: LCY-DUB (E70), DUB-LHR (319), LHR-PHL (772), PHL-LAX (321), LAX-HNL (752), HNL-LAX (752), LAX-LHR (388)

Article is dated 14 October.

I am sure the new ANA beauty is very fine by now and back to the skies.

I will have to SevenWaitSeven until 21 January to be on the flight from HND to FRA - first long haul for Princess Dreamliner.

It will not be the same aircraft as this HND-FRA will have the new "Staggered" Business Class seats for international operations. A two-cabin aircraft. The one they will fly to HKG is the domestic version - first delivered aircraft to ANA. "We Fly First".

The HND-FRA flight will be more like the true first international commercial flight as it is opened to all to fly on. The 26 October inaugural was by lottery, invitations, the press and a few rare outlandish priced Business seats for charity on Yahoo Japan and ebay (3 each).

This answers the question...what is ANA going to be doing with the 787 for a month before service...playing bumper cars...

Seriously, they need to stop toying with this thing and put the damn thing in service...they have had plenty of time to prepare for this plane...for crying out loud, the 748F went directly into service...rant over...

Some slight differences, you may note the 748F is not an entirely new design while the 787 has some quirks about it. The freighter is also not carrying passengers...

Pretty unfair comparison imho.

The 787 is a brand new aircraft with completely new systems and an all new flightdeck. It is also made up of many composite parts so not only do flight crews and cabin crew need to get used to it but also engineers and other maintenance staff.

The 748F has the exact same flight deck as the 747-400, many of the same systems with the main differences being in the wings, engines and the fuselage lengthening. Probably explains why the 748i hasn't sold very well as it isn't much of an upgauge on the 744. I am suprised the 748 1980s flight deck has not been replaced by a more modern 787/777 style full glass cockpit.

So will the damage to the engine cowl cause a performance penalty in the laminar flow? Remember the discussions on how Boeing will require the engines to all be white so as not to disturb the laminar flow. You would think that any type of surface damage would hinder performance, albeit slight.

For the 787 fuselage. The composite is a laminate type. Small damage to the skin (like a hole) can be covered with an aluminum sheet (or composite sheet) bolted on with fasteners (and sealant/adhesivve).

If the damage include the stringer and shear ties, then the repair may be a little more complicated.

I think there was a presentation floating out there to show how they were planning to do it.

I think you ill find just the opposite!

Bonded repairs are cheaper!

The fasteners used in a bolt-on repair being the most costly item!

A bonded repair may take longer, because of cure time.

Composites are not my specialty, but with the limited 787 structural knowledge I have, you can not use a bolt on repair on the 787. A few of the critical design features of the 787 are large single piece fuselage sections and integral (co-bonded) fuselage stringers, eliminating tens of skin joints and thousands of fasteners and therefore reducing weight and drag. Without bolt holes already in the fuselage (to join fuselage sections and stringers) to perform a bolt on repair on the 787 would require bolt holes to be drilled and drilling composites is a BIG problem. Drilling cured composites can de-laminate layers or fray fibers resulting in significant strength loss around the bolt hole.

This has probably not been tested in Boeing-training. So better test it before the inaugural service. After all, these things happen. No big deal if you ask me.

ANA has auctioned seats for the inaugural 787 flight...would you want to go forward with that plan without *two* service-ready aircraft in case one goes tech?

It's not that big deal...the OEM's do it all the time during initial build and all repair shops know how to do it because you have to do it to maintain many of today's components (nacelles, control surfaces, flap fairings, etc.).

It's clear from this thread that the 787 will be under tremendous scrutiny. No surprise there. We are talking about composites and repairs when it was only an an engine cowling getting scraped. I wonder how many of us half-expected the second paragraph in the story to begin, "Sadly, the aircraft will be a write-off ... "

True. You need a sharp bit when drilling in CFRP. And that bit won't stay sharp for long.

On the other hand, you don't need to de-bur every single hole in the CFRP because you don't have to worry about crack propragation.

Plenty of factors could've caused this incident. Just one of those things which happens from time to time at an airport, it's just unfortunate that on this day it was the 787! Sounds like the damage is merely cosmetic, nothing to worry about!
