Guest Guest Posted May 27, 2006 Share Posted May 27, 2006 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.

pylon500 Posted May 27, 2006 Share Posted May 27, 2006 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.

Guest micgrace Posted May 29, 2006 Share Posted May 29, 2006 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? Micgrace :) Link to comment Share on other sites More sharing options...
