Dave,

The same symptoms occurred in my IV-P.  In my case it was the door hanging
against one of the axle attach bolts.  The door did not show any damage.  It
was possible to get the gear up by slowing the airplane down to about 85
kias, cycle the gear and complete a normal retraction.

It would seem that this is not all that uncommon a problem.  Charlie Kohler
knew just what to do to correct it.  He advised me to add a 6 bid carbon
lay-up to the entire length of each main gear door.   I found that it was
further necessary to cut a new set of sliders with a ramp high enough to
bring the doors into firm contact when fully open.  The airload is such that
the doors never contact in flight.

  I've been flying with the doors in this configuration for more than 100
hours and there is no evidence that the doors ever touch each other.  As a
precaution I try to hold the airspeed at 110 kias until retraction is
complete.

Hope this helps.

Merrill Smith
