Bob,

It could well be the adhesive...however, the need for the adhesive  
was created by the failure of the two rivets that originally held it  
on for 260+ hours.

I have a photo of the door.  The first latch is somewhere just east  
of the Nellis range, and the second one is in a field just North of  
Heber Valley Airport in Utah...
