Transport Canada Engine Certification Data

[PPRuNeUser0211]

Anyone know where Transport Canada keep their engine certification data online? I've been using EASA data quite a lot in my project, but I'm looking for some data on PT6B-67A, which doesn't appear in EASA land, Cheers all!

Is it possible you're looking for a PT6A-67, or PT6C-67? I don't recall a PT6B with that dash number nor is there a B-67 listed in the FAA TCDS either.

That's really the issue - I've found data on every other variant I'm after. This one is only fitted to AC31 3. Definitely PT6B-67A

It appears the B-67 was only produced for the 313 and never certified under any western CAA. Perhaps a email to the CAAC can provide the data as they are the only ones who seem to have certified it for use?

The PT6B-67A is indeed unique to the Z8F/AC313, a rehashed Super Frelon. For reference it's simply a "-67" barrel in a "B" configuration.

The sale of this engine resulted in a serious (and deliberate) ITAR breach and consequential monitoring of all United Technologies divisions for ITAR compliance. Some may remember when you couldn't get a part out of Sikorsky without a signature from a Company Officer or the President. I'll let you read the settlement and draw your own conclusions. I doubt that you'll get any information from China, or P&W for that matter.

The TCDS for the PT6B-67A is available on the Transport Canada website, i can't post a link though. Try searching "NAPA issued certificates"

Hero! The power of pprune. Thanks team, I'd have never found that in a million years of googling! The above explanations make sense. My next question is why that particular model has never been sold to anyone else? No requirement for something in that class? I didn't know about the United Tech sanctions either, pretty interesting!
