Alan, raises a good question about the monowheel - can anyone who has
experienced a monowheel puncture on touch-down say what happened please?


On aircraft with the brake slave cylinder in the original (bottom)
position, you could imagine that landing on a flat tyre would be quite a
nasty event. The tyre must quickly snag the brake cylinder with
potentially vicious results. 

Apparently one solution is to move the monowheel brake cylinder to the
horizontal position but on some Europas insufficient rudder cable
clearance can prevent this - unless someone has come up with a neat
solution. Some mountain bikers fill their tubed tyres with some form of
self-healing foam - but is that a viable, permissible solution for an
aircraft?

Any views?

Best regards
Roger Mills

Hi Jerry and Forum,

Are you refering to a puncture on the mainwheel of the mono variant ? 

I suspect not. Does your advice apply to this situation as well ?
(avoiding lower tyre pressure).

How many out there have suffered a mono mainwheel puncture, particularly
away from home ?

... and how have you resolved the issue ? 

Like a random prop strike, it's one of the scenarios that I dread. I can
imagine being completely stuck !

Alan

One of my customers has had several punctures. The rest of us have had
few with more hours. Perhaps he chooses bad fields but someone who may
know suggested his punctures were due to low tyre pressures. He checked
and found his were low (not just the punctured one). I have no idea if
low pressure does make a tyre prone to puncture but its worth checking
the pressures in any case. Being a bit woolly on top I have taken to
writing my correct tyre pressures on the wheel rims in white paint so I
don't have to look it up.
