While I love to get inside information here, there seems to me a little problem with this account: the very small number of flights to date of the revised system.
Famously there was just one in the certification plan for the revised battery system. Also, I think, a handful under flight number BOE5 handling certification for an engine upgrade (mostly last week). Other than that, the reported recent flights (UAL ex Los Angeles, Qatar ex London) seem to have been relocations still carrying the old system.
My doubt on the runup to the situation does not address the possible truth of the weekly inspection requirement, which would be an unwelcome addition for several reasons. Still, 3 hours seems rather a lot unless the paperwork enormously outweighs the inspection work.
Please advise if you get updates on any aspect of this.
