The weight gain, stress effects the engines and other parts of the planes systems. It all new, no previous experience given the composite of the plane is new.
I do wonder if it is economies of scale that made AIR just go just the one supplier way. Not proven to be a great risk management strategy regardless.
I am not aware of any serious concerns over the fuselage of these new fangled plastic planes.
However there always exists the possibility/probability that some problem will emerge in the future.
Rolls-Royce recently (a few months ago) concluded that their fix for the blade longevity problem did not last that long and are reworking it.
Here is an interesting link with regard to an ongoing engine issue:

Great how they are experimenting with parts in the Trent 1000 engine through trial and error isn't it.
But Houston we have a problem, as I once watched a RR video that said there were 30,000 individual parts in those engines...that's a lot of potential trial and error
But no worries because on CNBC the other day they said RR are picking up the tab for all costs with this latest aspect of this long running fiasco.
I see RR provisioning is now up to a whopping 2.4 Billion pounds and I sure hope AIR are going to get their fair share of that compensation

"The news that a permanent fix for the engines would not be available until 2021 would be a blow for the airline, she said."

An interesting item has quietly emerged for road racing bicycles made of carbon fiber. Professional Tour deFrance level cyclists can apply above average stress loading to their cycles (rough road conditions, frame flexing, high speed judders, oscillations, resonance etc). The frames have been examined and found to have developed microscopic fracture lines not visible to the eye but detectable with ultrasonic tools used for testing pipes in the steel industry. Carbon fiber sheet is composed of millions of very thin threads "bonded" into place with epoxy resin. Individual fibers can break and/or de-laminate over time. Both of these materials are technically "inert" and as such ideal for manufacturing items that wont "rust", but oxidization is just one element of industrial processes, chemical bonding and slow degradation of certain chemical elements over time is normal. Carbon fiber is flexible when in sheet form, the glue "epoxy" is the "solid" part of the process, epoxy breaks down over time and will develop micro fractures when repeatedly exposed to stresses such a when used to connect/interface to metallic components. The micro fractures are normally not a concern due to the combined flexibility and high number of carbon fibers in the sheet, unless the cycle is used for more than 4 years...

My carbon bike is 7 years ....Presumably it would be how much use it has actually had and the type of use . NZ chips roads not the best ?

Mine is about the same. I dont quite reach the tour defrance level of energy... by a country mile.
The early versions had carbon to metal joints and I know they definitely had problems. Im hoping that they have found very effective ways to mitigate the joining effect, as modern aircraft have carbon wings...

AIR social media team asked whats your dream view from the window seat.
I responded - allowing punters to actually see out the windows (blinds up / tinting off)
Best response was:
Dream view?
A banner saying all further flights suspended until your aircraft can carry us without further damage to the earth's climate.
At the top of every bubble, everyone is convinced it's not yet a bubble.
