I wonder if others have problems in engaging these when rigging. Before
the flap root extensions were added it was difficult, with them it is a
real pain. I have tried two conditions 1) the self aligning bearing
lubricated and very free. Then the slightest engagement off-line and it
moves out of alignment completely. b) unlubricated and tight. Then it
won't move into alignment.
This all originates from the relative shapes of the pin (hemisphere on a
cylinder), and the socket (straight cylinder). If the pin had a conical
or paraboloidal) end, it would self align better. It can hardly be
reshaped in situ, and those who have already had to remove them (when the
length changed) will not want to do it again ! My only other thought is
to have a much bigger door than the 1" suggested, so that access is as
easy as it was before the extensions were added. It could be out of sight
in the lower surface, or perhaps a cut-out in the top, which would be
filled by a fuselage mounted plate when the flaps come up. Any other
ideas ?
