I dont remember time frame, the C1 through C11 are line checks, the C12 and the S-checks are done in heavy, cant remember the exact time frame for the C12, but I do believe its less than 48 months, you can do into the US maintenance system and do CCDAS and it will tell you what checks are done, and when the next checks are due and the time intervals.
