CAA to Part FCL
According to AIC W086 04NOV 10, one of the new privileges of a CRE (HPCA), traditionally an SPA qualification, is to 'conduct skill tests for ATPL (A) issue on SP HPCA types', which traditionally was an MPA privilege, hence my question.
So it appears that changing from CRE to TRE does make a difference as to who is authorised to perform MPA ATPL skill tests on HPCA aircraft.
