What was found
FOUND SAFETY ISSUES WITH ALL FOUR WING SPARS ON THIS AIRCRAFT. THE WOODEN SPARS HAD SEVERAL CRACKS AND VARIOUS OTHER DEFECTS. I HAVE ALSO E-MAILED PICTURES OF SOME OF THE MORE NOTICEABLE AREAS. THIS AIRCRAFT WAS RECENTLY RESTORED AND NEW FABRIC WAS INSTALLED OVER THE OLD WOOD SPARS. I SUSPECT THAT THIS AIRCRAFT PROBABLY HAD A GROUND LOOP OR 2 IN IT'S PAST HISTORY WHICH CAUSED MOST OF THESE FAILURES. ORIGINAL SPAR DESIGN WITH REINFORCEMENT PLATES NEAR THE INBOARD WING ATTACH POINTS ARE OF POOR DESIGN BECAUSE OF THE WAY THE WOOD SPAR IS MILLED DOWN TO ALLOW FOR THE PLATES TO BE ATTACHED AND STILL MAINTAIN ORIGINAL MATERIAL THICKNESS. THIS IS A WEAK SPOT AND VERY HARD TO INSPECT PROPERLY.
