I have a 52W with aux tanks outboard of the mains.  Each side holds 21 gals for a total of 74 gals.  The aux tanks are made by wetting wing bays (no bladder).  Why not do the same with your  52's. I believe the wing is identical.  Would require a few access panels fabricated to seal, vent, drain and to put the senders and output fittings in.  Engineering drawings could be optained from Aerostar or from an existing 52W.  No additional structural engineering. The 52W uses 2, cockpit switched, facet 24v pumps to move fuel from the aux tanks to the mains.

Is anyone doing this fuel tank conversion in the US? if so how much? On the same subject is anyone doing the Termikas TD conversion here in the States? Again at what price.

  Thanks Bill Wade

Modifying a stock Yak 52 for wet wing tanks has  proven to be a real problem.  They eventually leak...plain and  simple.  The wing was not designed for a wet wing cavity.  Making one  in the existing wings creates more problems than they are worth.  If one of  my customers mandates a wet wing tank modification to his stock, 1980's model  Yak 52, I ask them to sign a release which relieves me of any responsibility for  any and all problems that can (and will) occur with the wet wing tank  conversion.  Including the inevitable blue stains on the underside of the  wing, which as we know is the telltale sign of a 100LL avgas leak.

  

 For those that are interested, I will have the  first set of fuel tank bladders that we designed (yes, bladders) for the Yak 52  in the next couple of weeks.  They will replace the standard, metal fuel  tanks.  I will be testing them on my personal airplane.  Estimated  useable fuel will be in the 50 total gallons range giving us a real 2.5 hour  + airplane, PLUS 30 minutes reserve.  More information will be  available very soon.

Bill,

 No one that I know of is doing the wet wing tank  modification on the stock 52 and no one as far as I know is doing the TD  conversion here in the states on their stock 52.  As I said in my previous  email, a wet wing modification on the stock Yak 52's has been a  problem.  If you want more fuel, wait for the fuel bladders.  They  will go right into the existing fuel cavity.

Patience great one. A fix is in the works if all works out. That is all I can say for now. That also goes for the fix for Carbon Monoxide. Which is very high in the 52 and the 50 also. Just finished doing the primary flight profile measurements. All those little airframe seals are not lowering the levels down to safe limits ( PMEL – permissible  exposure limits) during start, taxi, TO, decent, landing and shutdown.

We just completed our first wet wing modification for a standard Yak-52.

9 gallons per side which pump into the mains.  We can go farther 

outboard for not a whole lot more labor.



We're quoting the second system at $6500.



E-mail me for more information and pictures!



Cheers,

Cliff

Cliff,

What is the estimated total time to complete the modification?

Termikas gets an extra 80 litres (17.6 imperial gallons) per SIDE from their 

wet wings, priced about the same.

Expect about 2 weeks roll-in to roll-out.

Cliff,

I had Anabaras in Lithuania do a wet wing mod for me when they did my plane. 

It leaked like hell form the day I got it to the point where I simply 

disconnected it. Liutauras at Anabaras would not even email me back. They 

also simply ran a vent line from the main aluminum tank about 3/4 of the way 

up into the new wet wing. Fuel would leak into the wet wing when the main 

was full and leak out.

Do you have any type of liquid sealer that you can recommend and a method 

to apply it? Thanks,

Cy Kissling Stuart Fl

That's like comparing apples and oranges.  It may cost the same when the 

airplane is already in Lithuania.  But if it's not in Lithuania, there IS no 

comparison.  Let's see - approximate cost to ship a set of wings in a 

container to LT from the US is now around $5K+ each way.  Plus $6500 for the 

wet wing conversion.  Plus if Cliff does the conversion, you can bet they 

will stand behind the conversion.  Not that Termikas won't.  But who's going 

to do the repair?  Most likely......Cliff Coy.
