Pratt & Whitney Canada (PWC) Authorized Kits for the PT6A Engines
We are aware of other vendors out there trying to sell their own kits under our PWC37410-108 and PWC374910-109 Part Numbers. See for yourself: we are the ONLY company authorized to use these Part Numbers as certified by Pratt & Whitney.
