I think that 7 days to check a lockwire und 21 days to do a 10 work-hour job is far away from grounding.
From your link above:
Estimated Costs
Action Labor cost Parts
cost
Cost per
product
Cost on U.S.
operators
Coupling inspection, o-ring
replacement, retainer ring
installation, blade seal
inspection, and lockwire
installation and blah blah...
10 work-hours X $85 per hour = $850 / parts cost $54 / cost per aircraft (only 3 aircraft registered in USA at this time) $904 / total cost for all 3 x USA registered aircraft $2,712
We have received no definitive data that would enable us to provide cost estimates for the oncondition
actions specified in this proposed AD.
I'd question whether or not the "10 work-hours" required can be conducted
concurrently (by say using 10 engineers - problem resolved in 1hr) or that this would involve disabling the aircraft from flying operations for
10 hours - a small fortune (loss) for airlines, especially the few operating this new Boeing...?!
I can almost imagine an Irish low-cost carrier contributing: "We were envisaging the replacement of some of our smaller Boeing B737s with B787s on certain routes. Unless the fuel leakages reach significant quantities, which cannot be recovered by simply adding 20 pence for access to the coin-operated toilets aboard our aircraft, sales of sandwiches recovered from the French autoroute opeartors the day before, or just excess baggage, we'll be reconsidering all options. Including relocating our HQ to Luxembourg for all online ticket sales.
