Cheers,

	Yesterday, a buddy and I went to the airport and recovered the

Europa wings on the trailer, from the hangar. The intent was to match same

to fuselage for purposes of rationalising feed-through sites for wiring and

odd items. By the way, these and the other surfaces were beautifully

finished by a local firm to a tough mirror finish.

	All was normal on the 30-minute trek back home, and we unloaded same

onto brackets built to set them vertically (nose-down) prior to installing

them. When we began the sequence, I noticed a discolouration on the port

leading edge and discovered a smashed leading edge about two inches in

diameter, right on the leading edge - right down into the blue foam.

	This corresponded to the position of the wing in the rubber strap

(lined with bubble-wrap). I noted that the pip-pin for the strap structure

hinge release sits dead-centre under the strap. Sure enough the strap was

pure (?) rubber and I could stretch it downward with just my fist. There is

no question that, given the odd bump neatly handled by the trailer, evolved

into a surge of the wing down until the pip-pin punctured the wing.

	This is going to lead to at least a week's delay, in rebuilding the

wing and then driving it about 70 miles on country roads to the now-retired

re-finisher. He took the tools/fixtures with him to his home airport.

	So this is a belated warning:

(a) reposition the clamp-folding pip-pin to another suitable site away from

the wing leading edge, and 

(b) replace the rubbery slings with some (preferably white) rubber with

cloth reinforcement to resist excess stretching. I'm still going to line

same with bubble wrap as I have saved acres of it and it works. 

	I will be canvassing McMaster-Carr and similar sources for same. If

you are light years ahead of me and already possess same, please advise.

All advice gratefully accepted.......

Hi Ferg,



Sorry about your mishap. I might add my adventure here:

The trailer i have has woven strings, from a material as used by lorries  

as strap-down.

On my way to the painter i noticed in the mirror that a wing was moving  

around more then i would expect, so i stopped a few miles down the road.  

Then became clear that both wings had moved backward, and that there was  

only 2 inches of spar left in the clamps. It would not have taken very  

long anymore before a wing went flying! The wind force on the fairing,  

together with bouncing in the straps had been more then the friction of  

the otherwise tight clamps. Securing both spars with a rope around the  

aileron mechanism is really needed!



Regards,



Jos Okhuijsen

Hi! Ferg

Sorry to hear of your misfortune, you must be "gutted".  Just for the

record my wing carriers are made of spent conveyor belting lined with

carpet attached by heavy duty upholstery glue. I don't tie the wings

down but the carriers are about 12"/15" wide thereby spreading the load.

However since my trailor weighs in, loaded, at about 3 tonnes and has a

double axle linked weight transfer suspension nowt bounces! I do think

though that to spread the load is very relevant since it reduces the psi

point loading on the wing. 

They are also fixed laterally by the pip pins through the spar holes.

Regards

Ferg,

I am sure the Europa community feels for you in your misery over the crunced 

in leading edge.

None would like the same misfortune

Best Wishes for a good recovery which I hope will be easier than you now 

think.

Just a quick note to those who kindly replied to my message about the punched wing leading edge - Thank you. It's always an advantage to hear from others and get the true word.

This is first time I've used this form of reply so hope it works

Ferg, 

I had the same happen to me last year, only I have the foam inserts not the rubber sling.  On a long haul from the airport to the house (at night) I was unaware that the foam had split allowing the wing to slide down and make contact.  Very frustrating.  Mine wings had been painted for two years, however, I had been fortunate up to that point in that the paint was in pristine condition.  So, I definitely feel your pain.  I have since made a new wing support for the trailer which is 12" wide, thus spreading out the load.  Good luck

The link below will give you some photos of a wing support and holder that I have used. I have used it several times to carry the aircraft in excess of 1000 miles without so much as a hint of damage. I work in the oil and gas industry we do a lot of work with vibration dampening. I asked the guys that run the shake tables about a design to prevent road damage to my wing and reduce stress on both the leading edge and spar. The outcome was a firm blocking system clamping down on the spar with the bell cranks tight up against and additionally a bungee cord holding the aileron bell crank to the hold down. The wing tip is supported by two layers of floor carpet. The first layer is held in place with a metal clamp attached to another bungee cord running over a boat roller and designed to support and hold the wing. A second layer of carpet is placed loose over the first and a plastic bin liner is added to the wing skin to prevent the carpet from scratching the paint. It ends up that the carpet fibers are a really great vibration damper. I use the 3m Blue painters tape to hold the plastic liner in place and also to wrap around the flap hinges to prevent the flaps from moving or bouncing up and down.

Ferg, 

 

Hope the repair goes well. 

 

There are "Colorworks" franchisees in Burlington and Oakville. These people do repair work for the auto dealerships, fixing small dings, dents, scrapes, blemishes etc. 

They have mobile vans with the paint equipment, and can match colour and airspray the damaged area. 

May be the easiest way of getting the paintwork re-done.
