Nothing new re the specific failure I reported a week or so ago, but some
thoughts on the subject.

Seems that there are at least two other similar failures noted.  That
seem to indicate a generic problem.

The GM3 linkage has self aligninig bearings at each end.  The inclination
is to install that linkage with the landing gear DOWN.  No problem there.
 But - -  with the LG retracted. there can be a consequential problem if
the two ends of the GM3 linkage are not co-planar, or nearly so.  With
the linkage folded  nearly double on itself, the two bearings have very
little "wiggle room" to self align.  If they are not nearly co-planar,
there could be significant forces generated to force the pressed-in
bearing out of the inboard GM3.

Just a theory.  <Dick Alden>        N425A      LNC2/320
