You may have excess friction or binding in = your system somewhere. To check the health of my gas strut, I free fall = the gear above 100kts. If I don't get a green on the nose gear right = away, I will very slowly bleed off airspeed until I see the strut pop into = place - usually around 100 kts. In an actual emergency extension, I would = slow down to 80 and let it come down with more authority, but this = technique shows me exactly how much margin I have in the gas strut. =20 from: Re: [LML] Re: nose gear bent-? pilot or mechanic error,Date: Thu, = 07 Jul 2005 <<......There are a number of places where friction or binding can occur = and prevent the standard gas strut from doing its job. The two links and = the nose gear must swing in the same plane during the entire retraction = cycle or else binding will occur. Excessive compression on the nose gear = bearings is another popular source of friction causing free fall difficulty= . Things to check: With the over center link disconnected from the nose = strut, it should swing freely, yet have no side play in the bearings. The = length of the spacer holding the two bearing plates apart is absolutely = critical. If it is too short the compression on the bearings will produce = friction. If it is too long you will have side play in the strut.=20 Once the bearings are ruled out as a source of friction, the alignment of = the over center linkage to the strut needs to be checked. A simple way of = doing this is to disconnect both the gas strut and hydraulic cylinder, so = that the linkage can be moved freely. With the nose strut in any position = from fully extended through fully retracted, the end of the over center = linkage should slide in and out of the from between the tabs on the nose = strut without applying any pressure to either tab. If at any time, the = links apply pressure to one tab or the other, then the axes of rotation = for the nose gear and the over center links are not parallel causing the = parts to swing through different planes.>> keep us posted, Chris Zavatson N91CZ 360 std www.N91CZ.com
