I considered the same solution, but have the impression that nose gear collapses are almost as common as mono collapses??

Frustrating and expensive indeed Paul Boulet N914PB ----- Original Message ---- From: Graeme Smith Sent: Friday, February 23, 2007 2:26:29 PM Subject: Europa-List: Undercarriage Overcentre Locking Greetings, Having suffered an undercarriage collapse during the takeoff roll on my monowheel, I am now pondering what corrective actions to take to prevent a re-ocurrence. As far as I can figure out, the overcentre locking went 'under centre' when the aircraft went over a large 'ski-jump undulation' at just below flying speed on takeoff from a grass strip. Having spent a lot of time and money cleaning up the mess and fitting a new prop etc, I'm reluctant to go flying again, even if I confine my operations to an absolutely glass-smooth runway, until I understand why it happened in the first place and have some degree of confidence that it won't happen again. I've looked for any possible 'builder variations' in this area to see if there is anything that I could have screwed up, but it seems that the geometry in this area is totally determined by the manufacture of the landing gear frame and the u/c components, what's more, this area has been rigorously inspected on several occasions by some very fastidious inspectors. (although my landing gear frame was modified in the factory to add reinforcing following some very early landing frame failures, it's possible that the geometry was affected during this mod). Are any other mono owners aware of the amount of overcentre on their installations, it would be interesting to see if there is much variation. On my aircraft, the degree of overcentre in the 'down and locked' position is 1/64 of hardly anything at all, (i.e. very small) and it occurs to me that shaving a few mm off the stops on the landing gear frame would be a good way of increasing the security of the overcentre locking. Question: has anyone tried this? Can anyone think of a reason why not?
