This was what I believed...until I watched this video (2:00 - 3:00): https://www.youtube.com/watch?v=HDsQIgUYvxY Remi Read this topic online here: http://forums.matronics.com/viewtopic.php?p=497022#497022 ________________________________ Message 2 _____________________________________ Time: 08:28:28 AM PST US From: Pete Subject: Europa-List: Frame/gear offset error? Hi Folks, My kit=99s (circa-2001) frame seem to have an offset error on the swi ng-arm tube centering tabs, making it not possible to drop the gear without i nterference. Anyone else seen this error? Looks like a fiddly fix to carefu lly grind down one tab and adding to the other. Picture is attached (if it gets through - also posted on the Europa Aircraf t Owners FB page) Thoughts/experiences anyone? Many thanks, Pete A239 ________________________________ Message 3 _____________________________________ Time: 06:14:18 PM PST US Subject: Europa-List: Re: Propeller? Gearbox? "Wow-wow-wow" resonance From: "JonathanMilbank" Bud and friends, Today I found what I believe is the "smoking gun" i.e. the possible cause of the strange "wow-wow-wow" resonance. While standing in front of the aircraft I saw that the propeller spinner is now displaced about 5mm to the left and is sagging about 4 mm. On standing closer it was easy to see that the 2 screws which secure the upper cowl nearest the spinner, are no longer equally spaced either side of the spinner. Voila! Off came the cowls and a couple of hours were spent closely investigating both the engine bearer frame ( a la Neville Eyre ) which is built to battleship standards and the undercarriage frame which was found to be crack free and as strongly secured to the fuselage tunnel as ever. A friend assisted by repeatedly lifting the engine up and down and side to side, while I used a strong light and felt all over for evidence of movement due to cracking. Then we swapped roles, before reaching the conclusion that both frames are sound and solid. So all this suggests to me that it could be time to replace the Lord engine suspension rubbers, which haven't been replaced in living memory or 12+ years! But I seem to recall that there was a bit of indignation in this forum about the excessive hardness of rubbers supplied by Europa. Please refresh my memory and let me know if the hardness problem was ever resolved. I've tried a search and trawling through various topics, to little avail. All I could find was someone's query about MT04 and Lord J 3608-1.
