skyfox fuel tank sealer

[Guest Guest]

Some time ago I read an article about skyfox fuel tank sloshing sealer

 

with some confusion as to what was used in the factory to carry out

 

this task.It was indeed Randolph 802 sloshing sealer.Now,the

 

interesting thing about this product,is that the product,in my opinion

 

should never of been used in the first place.The Aircraft

 

Spruce&Specialty Company book states that, and I quote from the

 

book, 'However,due to the recent increased use of automotive gasoline

 

as an approved fuel for certain aircraft,Sloshing Sealer is recommended

 

for use only in those fuel tanks using aviation or automotive gasolines

 

that DO NOT CONTAIN CERTAIN ADDITIVES SUCH AS METHANOL.USE OF FUELS

 

CONTAINING SUCH ADDITIVES COULD RESULT IN DETERIORATION OF THE

 

SEALER,RESULTING IN SERIOUS ENGINE PROBLEMS.' I informed the then

 

airworthiness inspector of Skyfox, P.G., and also the reigning

 

management of the time (another fascinating story of absolute incompetance by company management),I

 

even put it in writing at the time,that the product we probably should

 

of used was Randolph 912 Sloshing Sealer.Again,I will quote from the

 

same page of the book-

 

'This new Randolph 912 Sloshing Sealer is recommended as a superior

 

product to 802 Sloshing Sealer in fuel tanks using fuels containing

 

alcohol.' The airworthiness inspector and management at the time were a

 

very arrogant and indeed quite 'thick upstairs!' and thus,nothing was

 

ever done to rectify the potential problem.

 

cheers PT.

The fact that they (Skyfox) needed to use sloshing sealer in their fibreglass tanks, says a lot about the quality of their glass work? As

 

for Randolph 802 versus mogas, our 1983 LightWing had pop riveted alloy

 

wing tanks with 'ProSeal' on the joints and as a good measure the tanks

 

were sloshed.About eight years later (I think we changed from using Super to using Unleaded) we suddenly found our fuel filters clogging up with this brownish 'gunge'which was the sloshing compound breaking down (I'll have to get the photo and scan it!)Howard sent us his new glass tanks (unsloshed) and they're still going.Arthur.

Fuel tank sealer.

 

I did a my usual preflight on a Gazelle, you know, fuel sample, except little bits of fuel tank sealer came out with the sample. Not good.

 

I wonder if there is a cure, apart from replacing tank. Anyone know?
