It seems my nose gear failure was at least
partially caused by an overcenter link that was never properly
adjusted.
To be more precise, the cylinder extension put down
pressure on the link when down and locked.
Combine this pressure with the air spring and lots
of landings over 20 years - and it failed with one firm landing in gusty
wind.
Chris Zavatson suggested I look into the extension
length and pressure - thank you very much.
And, Angier Ames told me he solved the
problem by disassembling the cylinder and putting a shim inside to limit the
down travel.
Thanks for that too.
Does anyone else have another
suggestion. I've measured my linkage already and am planning to add
a shim.
I can see where this problem might develop if
the locknut that holds the rod end becomes loose. This would allow the
cylinder rod to unscrew itself in time making the extended length greater.
This locknut is completely hidden when assembled.
be safe,
