I don't quite follow what you mean by "Type Certificate" but the only calendar limited parts in the R44 ALS that I recall are the M/R and T/R
blades at 12 years. I believe all the GB items are all hourly limits in the ALS. The R22 is different with a few bearings at 12 years (I think). Did something change on the R44?
