Good morning Alan,
This kit is very common in the UK and I would guess that more than half of all
Europas have it fitted. In my case I simply got my inspector to sign in the log
book that I had fitted it correctly. It seems to me that your inspector's
signature
would keep the LAA happy and probably whoever you bought the engine from
got such an endorsement.
In order to accommodate the extra 15 mm or so which the kit necessitates, I cut
the equivalent length off the hoses and/or spigots of the air intake filter box.
But why did I decide to install the carb heat kit at all?
Carb ice is rare in Rotax 912 engines as fitted to Europas, but it happened once
to one of my syndicate group members after a very long time at 2000 rpm idle
on the ground, while he was waiting at the runway threshold holding point.
Conditions
were ideal for icing, being a chilly day with near 100% relative humidity
and quite low rpm. If he had lined up and commenced his take off run slightly
earlier, he might have experienced the the engine cut shortly after take
off rather than at the threshold.
This incident which I witnessed was enough to provoke me into buying and fitting
the Skydrive kit without delay. Even though it keeps the carburettor bodies
permanently warmed, the engine power doesn't seem to have been significantly
affected.
