Hi,
I'm trying to find a copy of an S92 noise certificate. I have found an EASA type certificate that mentions that the aircraft complies with ICAO Annex 16 etc but can't find a specific noise certificate. Does anyone have a link that may point me in the correct direction?
Many thanks.

It's in the last page of the Performace section of the RFM (Pt1 Section IV)

They were obtained by analysis of approved data from noise tests conducted under the provisions of FAR Part 36, Amendment 36-24.
