Steve, if you are looking for just the tail WHEEL itself and nothing else... if
you run out of luck here, try the Sukhoi parts dealers.
The Sukhoi's, (26,29,31) series use the exact same tailwheel as the YAK-50.
Good luck,
Mark Bitterlich
p.s. A number of Sukhoi aerobatic pilots have replaced their stock tailwheel with
one made of solid rubber. Stands to reason you could do the same thing on
the 50 if you got really desperate.

| Subject: | Yak-52 fuel starvation |
My 1985 Yak-52=99s engine quite about 3 miles from the airport
last Saturday. After some rapid pumping on the hand primer, the engine
fired then quite again, it repeated this several times before running
without stopping although somewhat on the rough side. After landing,
runup for over 1 minute was normal. Right tank was empty and the left
tank had about 10 gallons. I have not torn into the system yet, but
have been told to check the screens for debris, and the flexible fuel
lines for cavitation. I consulted Dennis Savarese and he said that the
right tank running out of fuel would not stop fuel flow to the engine.
Anyone have any thoughts on this subject and what to check while I am
going through the system?

The right tank out of fuel could well cause the problem. If you were
banking or the ball was not centered for any reason, the non return
flapper valves on the header tank could choose the empty tank and suck
air instead of fuel.

Same happened to me with my 18T with an empty left tank and 60L in the
right. It was after a rapid descent from 8000 to 1500 feet, 22 miles
off the coast of France
and engine stopped with just a wind milling prop.
Did the same, steep left 360 with lots of pumping and it started again,
500=99 above the water and it got me the 22 miles I had left to
Cannes. Checked fuel filters but they were clean.
I also suspect it sucked air from the empty tank and stopped because of
that.
I now try to fly with fuel in both tanks.

George,
If I am not confused I believe Mr. Burke has been modified to fuel bladders.
I'm totally clueless on this with the bladders in place of the metal tanks.

| Subject: | Re: Yak-52 fuel starvation |
Jim,=0AI gave you some things to check regarding the fuel system.=C2- ie:
fuel screens etc.=C2- Since you have never checked them before and as I
told you, the foam in the bladders may have some foam dust from the manufac
turing process which easily can block or reduce the flow through the fine f
uel screen.=C2- If you haven't checked it, you may want to do that.=0A=0A
I also explained to you about the fuel junction below the front seat.=C2-
Both tanks feed to this common point.=C2- The flapper valves on each sid
e of this junction do not block fuel from flowing from the tank.=C2- They
are designed to prevent fuel transferring between the tanks, particularly
during slips or yawing of the airplane.=0A=0ADid you check the fuel screens

fuel starvation=0A =0A=0A=0AThe right tank out of fuel could well cause the
problem. If you were banking or the ball was not centered for any reason,
the non return flapper valves on the header tank could choose the empty tan
k and suck air instead of fuel. =0AGeorge Coy=0A=C2-=0AFrom:owner-yak-lis
