REFLECTOR: Nose wheel shimmy

[Scott Derrick]

Kirk,

Every time I hear about an "incurable" nose gear shimmy I wonder, what 
is different.  There are too many flying V's with no problem, like my 
airplane for this to be a design flaw. 

I experienced mild shimmy one time. After pulling up to the hanger I 
discovered the nose wheel was almost free spinning. I had just replaced 
the nose wheel tire and "thought" I had tightened it enough when it was 
on the jacks but didn't check during pre-flight. Its a must item on my 
pre-flight now. 450 hours and only that one time.

If Velocity has a manufacturing problem with the nose gear strut where 
the angle is that far off that would explain it.  We already know a few 
were manufactured with the wrong hardness process.  This really sounds 
like Velocity "sometimes" has a QA problem for OEM parts.

thanks for the info,

Scott
