Take a look at the schematic. I further suggest that ALL CJ's are updated at the next annual to the YAK 52 emg system of separating the 2 circuits. Gives greater redundancy. Again, this was changed on the Y52 to that of the earlier YAK11, YAK 18, Yak 18A, Yak 50. I suspect because of the type of accident that happened in Australia 2 years back. Manufactures learn from experience!! Do owners?? Some how if it costs money I suspect they don't :)) MJ. The emergency bottle on my Yak 52 has a slow leak and I just today noticed (I usually just fill it on the ground before flight) that the engine pump isn't filling the bottle in flight. I am guessing that the 2 are somehow connected (sticking valve between the pump and the bottle?) but was hoping one of you smart guys might have some insight into my problem. Thanks.

Any suggestions on how best to proceed? What features should I look for? What should I look out for? Any and all advice would be appreciated.

I know that this is obvious but with no knowledge you should buy from someone with a track record in the industry. This is a small community and bad experiences spread faster than Montezuma's revenge on a Spanish holiday resort. Some names from my experience. I bought my first Yak from Mark Jeffries in the UK. It is a beautiful aircraft and I never had a problem with her. When I came to the US, with more knowledge, I bought privately and she is a wonderful aircraft. She was originally imported by George Coy in VT. I have had many dealings with George and have always found them to be reliable and very good. I have also had dealings with Carl Hayes in San Diego. He and Jill are also very knowledgeable and I have always found them a pleasure to do business with. There are very many people out there who will offer you deals on wheels. Trouble is that turning these deals into deals on wings can be expensive. I think my advice is to trust those who know. They have their reputations at stake and it is certainly in their interest to provide you good service. Any of the folks above will do you proud. It just depends where you live. When you get your bird I can recommend Tom Johnson at Cannon Aviation insurance, a fellow Yak owner, he loves these birds as much as we do. Not much specific engineering help but, I feel, as important a bit of advice as telling you to check all bulletins are up to date. If you buy from a good source they will be.

I had not heard of the accident you mentioned, would you please expand on that.

When we pushed the primer the powers went up.The primer was well and this seems to be a gasoline problem. We checked all the filters and at the end we changed the carburator. After that the engine runs well. Probably there was anything wrong there. The mechanics told something about an anerobic sensor, but I dont know what is this. Thank you for all your cooperation.
