Hi Jonathan
You will need to get the plane sitting with the horizontal datum set to
zero, I found that some 6x12in pieces of 1/2 inch chip board were useful to
pack up under my main wheels to achieve this. As for special jacks, I just
got under the wing on the side to be lifted and put my back against the
underside of the wing and lifted, remember its not going to be too heavy I
hope! Best of luck Richard

Subject: Europa-List: Re: Weight and Balance Scales
What's different about doing the weight and balance operation for a trigear,
compared with a monowheel? I'm just approaching the end of a mono- to tri-
conversion and I've booked my inspector to come and do the business later
this month.
He's done many weighings for many aircraft types and has all the necessary
kit. But I have the original instructions for this task in my old Europa
Owners Manual stating that the 0 datum is at the forward face of the
cowling, whereas these days the correct position is measured 29.25" forward
---From the rear edge of the cowling joggle in the fuselage.
Apart from that we'll need to measure the stations of the wheel centres aft
of the 0 datum and he'll use all that info including weight measured at each
wheel to make his calculations.
All I'm asking you kind people out there is to warn me of any "gotchas" so
that I don't embarrass myself when he arrives from 60 miles away. Like what
essential items should I provide? I already have realised that there's no
dedicated jacking point near each main wheel axle. In the absence of any
better suggestion, I'm going to make a little steel bracket which bolts on
through the spare holes in the brake torque plate and has a welded
projection for a trolley jack to lift against. Is this how it's done?
Yours in eager anticipation. Jonathan
