Civilian DHC-5 Buffalo

[Treetopflyer]

Hi all,

I figured this is the best place to ask this question as there is probably amongst you quite a few ex-Buf' drivers:

The DHC-5D is the latest Buffalo version, mostly sold to foreign military operators. It features CT64-820-4 engines & 49000 lbs MTOW.

There is no mention about the DHC-5D version on Transport Canada civilian type certificate list. The closest I can find there is the DHC-5E.

--> My question: can anyone of you tell me what modifications need to be made to a military -5D to bring it to civilian -5E standards?

Thanks in advance.
