I would need a field or an STC from them to install it here in Canada,,, I am aware of one MP-14 installed here in Canada !!! 1999,, which at the time, he was allotted an stc based on a letter that was written from Nanchang at the time that this was a approved engine that could be installed. ( Lost, filed away, or misplaced copy) Question if any one can help is,, does anyone have a copy, or have documentation from Nanchang that it is allowed. I sure would like to have this so I can present my case to Transport Canada.

Annealing before welding might help but the metal is probably an alloy that doesn't weld well. Annealing will burn off the paint So you can't win. -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of danbooker Sent: Wednesday, January 18, 2017 4:36 PM Subject: Yak-List: Crack fix Just wondering what is the best way to fix small cracks in the aluminum fairings starting around the screw holes?

Interestingly we in the UK are allowed to fly Yak 50 and 52 only on the basis that they are "ex-military", since we do not have any form of an experimental category. The Nanchang, similarly, fits into the same category. We have recently sold an M 14 P to a UK customer to put into his Nanchang, but he is having a bureaucratic nightmare with UK CAA to authorise the conversion. They have asked for stress calculations on the engine mounts; proof that the engine will be sufficiently cooled et cetera. I would be very doubtful whether there is any "official" documentation from China authorising the installation of the Russian engine, but I could be wrong!
