Don't know.  If Lancair did the mod I=20= think=20 they put an "A" after the serial # on the bottom of the flange.  I= f=20 the centering mod was done, I think the flange was changed.  Isn't this= =20 noted in the aircraft log?  Maybe Lancair would have a record if the pr= ior=20 owner had the strut serviced there.
