Hi list,
I smelled a a *very slight* fuel scent in the cockpit today and went fishing for a fuel leak.

It looks like the rigid ~3/4" dia tube that links main & aux tanks has developed a c ...

One quick new datapoint (this problem is notoriously hard to reproduce). Did have another occurrence just a few days ago. Mag checked and there was zero difference between sides.

OK, here I am again with the same problem. Coming into the break today at home airport at full throttle / 82% rpm, all of a sudden had the same engine vibe/ roughness. Pulling throttle back 1/4 did no ...

O great Yak-list:
Does anyone have access to factory-recommended strut pressures for the Yak-50 MLG and tailwheel? We've "felt our way to it" after a strut rebuild but would be good to unde ...

Thanks! Yep, in touch with Mike now.

Also Doug Sapp recommended a "Final Filter" to be added in front of the landing gear selector valve to filter out any foreign matter that we're going ...

If I understand you correctly... when I did this, it was really difficult to align the upper end of the tube into the core. What ended up working was connecting the bottom connection to the cylinder w ...

Hi List,
Awhile back I wrote the list mentioning that there was rust-colored dust coming out of my landing gear selector valve handle.

The (relative) good news is that we've located the rust in a ...

Hi All,
Am looking to buy a spare Series II M14P/PF motor. Would look at a wide range of ages.

If anyone has one they are looking to sell, please contact me off list: apatton (at) gmail.com
Thank ...

Hi All,
Does anyone know if there is any sort of task card / instruction set to replace the seals on a Yak-50 main landing gear strut?

Have been told there are 4 seals (and have ordered kit from M ...

What's interesting is that I tried shutting off the plane today by pulling the fuel shutoff valve several times. The engine dies around 10sec later, but the carb still drips! Was not expecting that.

Hi All,
I've noticed twice now that my carb (overhauled unit w/ ~50 hrs on it) will leak gas after I land and refuel.

More detail:

ø It seems to leak through the throat of the carb
ø It drip ...

Hi all,
I've had a landing gear handle with an intermittent air leak on my Yak-50. I say "intermittent" because it emits a very faint hissing noise when the main air is on... have been flyi ...

An update! Have been much delayed by work and other undesirable activities in my troubleshooting.

Yesterday I pulled cowl and checked tightness of intake tube connections as recommended. Visually i ...

Firstly: huge thanks for all the responses! Smile

Richard - yes, I am having a hard time believing that it could be a ignition coil, with the overhauled mags being so young. But I will try to t/s ag ...

O Gods of M14:
Here's a riddle for you.

I have a Yak-50 with a stock M14P. I have been flying it regularly since I purchased it around 8mo and 40hr ago. It is a very stock airplane (no digital eng ...

Just to confirm - Richard is indeed correct and Watts Tyres (http://wattsaviation.co.uk/) were happy to fix me up with new tailwheel innertubes. The tires themselves are currently on backorder.

Hi all,
I am now faced with a leaky tailwheel innertube.

Does anyone have a good source for original versions of these OR is there some sort of stem (not filler) extension/modification? The Desser ...

Hi All,
I have a friend who is looking to make a Garmin G3X tach display work with the M14.

Does anyone have experience in doing this?
Many thanks,
Andrew

Hi All,
Having ~15h time in my 2nd Yak-50 right now, I am moving away from the "that's just how the airplanes are" perspective I had during my first 200h hours in the old airplane and tryin ...

Hi Richard - in the past it has helped to be able to google search things like this via p/n (especially if there were 20,000 made for Mi-17 helos). Worth a shot.
Best
Andrew
