No. It's for (A) licences only.
Apparently this might change, according to a quick response I got from EASA:
Thanks for your mail to EASA and your query related to EASA SIB 2011-01R2.
EASA confirm that, for the time being, this SIB is only applicable for aeroplanes (not rotorcraft).
Please note however that EASA is in contact with the different rotorcraft
Design Approval Holders to verify whether this SIB can be extended to
their respective rotorcrafts.
When conclusions are made, if possible, EASA should amend the SIB to
extend its scope.
