Do you have daily comparisons against the B777 as well?
Probably not - but what's the global 777 fleet size compared to the 787? With Japan being the most prolific user of the type and with both public and pilots expressing concern/subjecting to scruitiny ANY event is going to be reported - and 2 (minor) events in two days on a fleet of 50ish aircraft resulting in a cnx and a turn back isn't great
PR.
The problem is if there are multiple sensor/valve/switch events then questions start to be raised about quality. Is there not already history of nuts working loose causing minor scorching, misfit battery boxes/tape over sensors?
