Stuck Nose Strut C-205

Stuck Nose Strut C-205

I'm having continuing problem with my nose strut being fully extended upon landing and hanging up (or sticking) in the extented position. When the strut is extended, of course the nose wheel is locked and won't turn and makes plane difficult to control while going down runway and turning off runway. Eventually after I hit a rough spot on taxiway (or hard landing) the nose strut will drop to the normal position and I regain control of nose wheel steering.

This problem has been going on for several years. I've had that strut assembly apart many times and many parts replaced (and lots of $$$$$)...and this problem hasn't gone away. I've hired a couple of mechanics to look at and they can't come up with a solution.

This Strut is on early (1963) C-205. I believe it is the same model found on early C-182's.

Has anybody had a similar problem and found a solution.Thanks, Bill

Re: Stuck Nose Strut C-205

YUP!!! Had that problem with a customer's 175. Several things to look at. Make sure the torque links aren't too tight and lubed properly...with weight ON the nose tire you can disconnect the torque links at the top pivot and then move them to get a feel for tightness and condition. Next, with everything hooked up properly, extend the strut fully and CLEAN that thing ( I wipe it down with a little avgas on a clean rag )...then lube the chrome with LPS-2. This keeps the o-ring from rolling inside and helps the strut work properly. A rag and can of lube should be part of your preflight and you really should wipe down the exposed chrome and lube as often as you can. Don't use hydraulic fluid to lube the chrome...it will dry in flight and turn into glue...collecting all the dirt and junk and dragging that up into the wiper and, worse, cutting the o-ring. Remember, in flight that strut is fully extended...the lube you use should be good enough to stay on there. In the Air Force we used VVL-800C....an aerosol light weapons oil like 3-in-1 oil. I've found LPS-2 to be perfect and really helps that oleo do its thing. Obviously, the strut needs to be serviced correctly with fresh MIL-H-5606A hydraulic fluid and nitrogen...not air. Using a strut-pump or air compressor introduces water into the strut....not a good thing. I reseal these things all the time and you wouldn't believe what the insides look like on some of them. Hope this helps.

Make sure that you do not have too much pressure in the strut.  I did this once on a C-205 and it acted the same way as the one you described.

Re: Stuck Nose Strut C-205

The Aircraft Maintenance Manual has some very good instructions about how to maintain and service the nose gear strut.  The AMM is available through Cessna.  It all works good on my -205.
