Puncture preventing sealant in light aircraft tyres?
Punctures and under inflated tyres seem to be a common problem on gliders, particularly on tailwheels, given the relatively thin tread and low volume of the tube. As a result, I asked my technical examiner if I could put a pre-emptive sealant of the type used on bicycles and baby buggies in mine to prevent smaller holes causing a flat. His reply was that this would constitute a modification and invalidate the insurance. Fair enough, I won't do it then, but I just wondered if anyone in the UK has experience of trying to get approval to use the stuff in their aircraft tyre?
Is anyone aware of any issues that sealants could have on tubed tyres apart from the possibility of putting wheels out of balance?
Have you tried a sealant in an aircraft tyre and did it work?
