Well the FAA MMEL says this about the SHZ-760 DAFCS:
May be inoperative for:
a) VFR operations.
OR
b) One helipilot may be inoperative for two pilot IFR operations provided one pitch, roll, and yaw channel
remains operative and limitations listed in the RFM and applicable supplements are complied with.
So, it's not clear if you are talking about a two pilot or single pilot operation.
More to the point, is not whether you can fly with one helipilot (for 3 days, in this case) but that the snag is being continuously re-defered.
