Fuel inlet skin deformation. I forget whos plane this was, but think it was in AZ.
We are hoping Balsa/ BID and keeping fuel hose stress off filler will prevent both print through and this.
Bill,
In the early days (1996)the manual stated that the plastic 'cobra' tube
should be fibre glassed with Bid directly onto the fuselage skin in two
places.
It was then found on early models that exposure to the sun on a hot day
would cause the cobra to expand and therefore deform the fuselage skin
inwards. This happened to me. I then found via the builders web, that other
people were reinforcing the inside fuse skin with BID layers and placing
blue foam between the cobra and fuselage skin to absorb that expansion. I
am not sure if that was a Europa Club Mod or Company Mod however
it does avoid that deformation. I had to take my cobra out, push the skin
back out with the help of hot water over the outside and my son pushing
from the inside on a moulded piece of wood! Then reinforce the inside
fuselage skin, blue foam between and replace the cobra with new Bid
brackets.
Why it happened to me? I left the aircraft out in the open on a very hot 33
degree C day without the reinforcement.
Does it now say not to affix it to the fuseskin? If not, then do they expect
it to support itself, or the cover to support it?
