Boeing yanks Air Canada 787 from service over structural issue

From https://theaircurrent.com/aviation-s...uctural-issue/

“Two manufacturing issues compromised an area of the structure in the rear of the 787 that is unable to withstand the maximum stress that would be experienced by the aircraft in service and could fail.

Boeing earlier this week instructed airlines to pull a batch of eight recently-manufactured 787 Dreamliners from service, prompting their immediate grounding, after the plane maker determined that a manufacturing issue undermined the strength of an area of the jet’s carbon fiber composite structure.

So far, eight 787s — all built in the last few years — have been withdrawn from flying. Aircraft for United Airlines, Singapore Airlines and Air Canada are impacted by the impromptu grounding, according to a person familiar with the situation.”


Any idea which AC frame is at risk?

It would appear that UA and SQ only got one each, so the last six should be AC's?

Mind you, odds are that they are not really needed at this point. It appears neither of the other two are currently in service...

Given it includes 78Xs, I assume it is one of AC's most recent 789s...

Of these, the final fin, 859/C-FVNF hasn't flown since the weekend (unlike its compatriots):

That would be my guess, at least!

EDIT: I assumed it was only 1 AC aircraft... so I may be wrong

Does anyone have any update on this and if it will affect the current schedule?

I heard on the news that 8 Air Canada aircraft were involved, also Singapore Airlines, United etc.

With 737s and now some 787s parked, there must be some serious dollars in compensation going AC way??

According to OP's article from The Air Current, I believe it is 8 787s in total which have this manufacturing defect. Not all 8 from AC though. Hard to tell which fins though since AC has parked many of its 789s given COVID.

Yes that appears correct--on another site:

Dreamliners Grounded

"Boeing declined to identify the airlines involved, but United Airlines, Air Canada and Singapore Airlines confirmed that each has one plane grounded for inspection."

...the affected airframes are from a batch produced sequentially in 2019,...

I doubt the airlines involved can prove much of a financial impact for compensation. All of them have way more frames then they need.

AC list 2 789s produced in 2019
  • C-FVND Fin 858 - February 2019
  • C-FVNF Fin 859 - April 2019
C-FVND has been flying regularly but C-FVNF has been in YYZ since the 25th (and was flying regularly before that)

I flew on C-FVNF in late July. Yeesh.

So narrowing things down to the two AC jets delivered in 2019, it would appear to be fin 858 (C-FVND) - Boeing's 812th unit produced since both United and Singapore Airlines have nearby airframes. In the case of C-FVNF, there is a nearby United but not Singapore delivery.

If these assumptions are correct and the airframes were sequentially built according to the line numbers, then airlines affected would include:
Air Canada
United
Norwegian Air
Shanghai Airlines (x2)
Westjet (1 or possibly 2)

Possibles:
ANA
Korean
https://www.airfleets.net/listing/b787-4-lndesc.htm

Take the above analysis with a grain of salt since it is unclear whether this is sequential production at one site or both sites combined (i.e. Charleston vs. Everett)

There apparently was a -10 from SQ.

Just splitting hair here... But technically FIN stands for Fleet Identification Number, so FIN goes with a number (e.g. FIN 858). C-FVND would be the actual registration of the aircraft.
