Can we please have more info and discussion on the issues the aircraft faced before turnaround, eg the PAX reported electrical issues.
Also, Yasmin Vora (sadly a PAX on AI141), reported on a phone call that the aircon wasn't working immediately before takeoff.
What maintenance would have been performed to rectify these electrical malfunctions and is it possible this impacted critical systems?
Is it possible maintenance crew thought they'd addressed an 'intermittent fault' but failed to do so, if so, what could this have been?
Thanks.

CALLOUT TO MAINTENANCE CREW!

Can we please have a productive discussion on maintenance, to examine a new area and avoid the hamster wheel? Can someone from turnaround crew working on 787's generally (or ex A-I staff) comment on what standard checks are performed in the allocated time?

PAX have reported cabin issues on the inbound flight, (and other A-I flights), from no aircon for the whole flight to unresponsive screens etc. TDRacer has explained that the FADEC is shielded from other electrical systems. However, is there ANY correlation with these cabin malfunctions and the crash other than 'poor maintenance' we can find here? E.g. what if one of Air Canada's 787's entered YYZ with the packs malfunctioning - what inspection and maintenance would be performed? C ould a maintenance engineer working on fixing the packs do something to trigger a later plane-wide power loss? Or could non-functioning cabin electrics give us a clue as to other more fatal issues present? Could the system isolation protections have failed somehow? E.g. water ingress?

*Each time I post this, it gets ignored, but it's an unexplored area and my view is maintenance may have played a large part in this crash, - please help to narrow it down. Thanks.

I really think this is worth looking at. I keep asking a maintenance engineer to comment on what they'd do if a 787 with these issues presented itself to them on a turnaround shift and whether those faults could be connected to engine failure in some way.

This. If power was lost first, it's complicated. If switches to cutoff was first, it may be a simple and unpalatable answer.

One suggestion about why the report was sanitised and a fuller transcript was not provided could be to delay public reaction on this and avoid copycat events.
Jump seaters should be mandatory on all flights. On AS2059 the jumpseater maniac was overpowered by the other pilots. Two against one is better than pilot against pilot.
The 10 second delay could be explained by a cabin altercation when one pilot saw the other one deliberately perform the cutoff.

and frankly having spoken to some of these cabin crew who are quite open about their mental \x91struggles\x92 I can\x92t say I\x92d feel more secure with them sat out of my eye line but within reach of certain critical controls\x85.

wasn\x92t the 2 person rule initiated after Germanwings and then quite quickly abandoned because many airlines saw the risks of cabin crew in the flight deck more routinely with a single pilot as more of a risk factor than the alternative?
not cabin crew. Suggestion was for 3 fully trained pilots to monitor one another.
