Bill,

 

I ran into the same problem and I understand this is inherit in the legacy.  Check your core length from the leading edge of the wing to the “outside”  flap hinge on the underside of the wing.  Compare both sides.  I believe you will find that the right-wing is about ¾” of an inch narrower compared to left wing.

The fix I came up was to shim the right outside hinge bracket to correct the placement of the flap.  The other item was the outside hinge arm on the right flap was not located symmetrical compared to left flap. So I removed the right outside hinge arm fill the holes and redrilled. This brought the flap into acceptable tolerances for my aircraft.

 

This is a note from my log of the time when I ran into the problem.

“Measured flaps hinge placement from right to left.  Found that the right outside flap change is three quarters of an inch shorter compared to the right flap.  The problem is the core length at the outside hinges for the flaps comparing right leaning to the left wing.  It is found that the core length on the right-wing is shorter.

Removed flaps and compared hinged arm mounting points.  Found that the right outside hinge is not mounted as the same to left.”

 

Bill where are you located?  I see that you are with BellSouth.
