Narrative:

Transition from group 1 to group 2 aircraft I completed IOE. Per company instructions the check airman signed off my flight record and I began line flying per company instructions, then learned that the 121 group 1 FAA inspector's signature did not constitute approval for 121 group 2 aircraft. I halted my line flying until a group 2 FAA observation ride and signature could be completed and was completed successfully.
