(Tony Renshaw) ________________________________ Message 1 _____________________________________ Time: 12:59:01 AM PST US From: Nigel Graham Subject: Re: Europa-List: DOT4 and filling the monowheel brake line Hi Ferg, I was about to respond when Nev replied with the same suggestion. I have recently worked on two XS Mono kits that have been well stored (warm and dry) for the last twelve years. As a matter of course, I strip and inspect all components before assembling and on both I found that the brake slave cylinder pistons were stuck fast. Using a compressed air line to pop them out, I discovered that both were covered in a glutinous substance (see Picture). I am not sure what this is but would hazard a guess that it is old hydraulic fluid that would have been used to lubricate the piston during manufacture and being hygroscopic, has absorbed water over the years and degraded. I would suggest dismantling all of your hydraulic components and carefully cleaning and reassembling with fresh hydraulic fluid. I pretty sure that you will then be able to bleed the system as described by others. As an aside, I am certain that this is the cause of high brake disc and pad wear with associated hot discs that other mono pilots have complained about over the years. If you intend to keep the aircraft and have a desire to reduce subsequent maintenance, I would also highly recommend having all the components anodised. I have done this to mine and can send picture offline if you are interested.

My unit had been stored for a similar time. After soaking in various fluids for several weeks, using heat and compressed air to no avail, I borrowed the hand pump from a hydraulic press which finally shifted to piston. The piston was dry and so badly corroded I turned up a new one, also adding concentric grooves to the rear face to allow fluid easier access to the piston when fully retracted. The bore of the cylinder I was able to salvage.

The fault was mine, the stupidy rampant. I discovered a stuck piston in the reservoir/lever component, due to deterioration in the piston rings/cap - sitting for 5 years without inspection. The jammed lever gave clue, so opened up the piston area, replaced the cap and ring and cleaned it. Perfect BUT forgot the condition when I installed the system and ignored the brake cylinder. There we were, squeezing wildly on the syringe, dripping fluid all over the place. Finally sense slowly prevailed, I took out the brake cylinder and the piston was frozen solid. Took it to a nearby brake repair facility and in twenty minutes we had it cleaned. (Thanks, Neville) I bought another horse syringe, clipped the nozzle to increase the end diameter to fit and screw into the top master cylinder filler, (Upper Syringe). I then borrowed a neighbour's boroscope and aimed it at the upper syringe so I could monitor progress while below.. Re-assembled the system. Then I created a suction by pulling the upper syringe to get some suction. Loaded a 600 ml syringe and applied fluid to released bleed valve below. Magic - flowed in like water... When the boroscope showed fluid bubbling into the upper syringe, I pumped the bottom one until no more bubbles arose in it , pulled the bottom to drag the meniscus down to the cap level and removed and capped the master cylinder.. Pulled the bottom syringe, closed the bleed valve, and tried the lever. Pressure, no spongy response and the wheel brakes.......! Now I know if I had checked both cylinders properly, read the clues and thought a little more about it, I wouldn't have disturbed my buddies, would have done the job, and saved gas, 15 dollars, and a day's exertion, plus the celean-up........ Thanks again, Max, Remi and Neville!

I am not 100% sure on this myself, as I have been Retired for some years and no longer a CAA Examiner. But just posting the comments of a friend who is a currently an Examiner. He seems to think you can not do an IMC rating using a Europa. It must be a certified aeroplane with the appropriate licenced equipment. So it would be wise to check this out for yourself if you are talking about a UK rating, I asked the question just out of interest,as I have an nppl and no interest in an IMC Rating. Regards.

The rotax flanges are known to crack and come off the metal flange. These new flanges are aluminum flanges tha use a rubber joiner to connect to the carb with two clamps. All that will ever be needed to be replaced is a $3 rubber. I have a few of these made up and am looking for someone in the US that is interested in trying a set of these and reporting their thoughts on them. If anyone is interested please email me off list to discuss it.

From: Tony Renshaw Gidday, Whilst working around in the lower fuse it has concerned me that my fuselage has what appears to be an intentional absence of core material such that an obvious weakness exists in the fuselage directly above the penetrations for the flap drive cross tube. Has anyone externally reinforced this area, by a dding core material and strapping it in place, encapsulating it, and resulti ng in a conventional sandwich construction concept?
