## Discrepancy

FWD WING ATTACHMENTS, LEFT & RIGHT WINGS, FWD & AFT BRACKETS WERE NEVER RIVETED TO TOP & BOTTOM WING SKINS & INBOARD RIB FLANGES ALLOWING ALL LOADING TO BE TAKEN BY BRACKET FLANGES & INBD WING RIBS. ALL 4 BRACKETS ARE CRACKED. PICTURES AVAILABLE.  IT SEEMED MORE THAN COINCIDENTAL TO ME THAT THE FOUR RIVETS NEEDED TO ATTACH THE WING SKIN TO THE RIB AND THE ATTACHMENT BRACKET WERE MISSING ON BOTH WINGS, TOP AND BOTTOM. PERHAPS THERE WAS A MISTAKE ON THE ASSEMBLY DRAWING AT THE TIME OF MANUFACTURE. THE HOLES WERE NEVER EVEN DRILLED FOR THE RIVETS. THE AIRCRAFT WAS MANUF. IN 1978, 4 NEWER MODELS WERE INSPECTED AND FOUND TO BE CORRECTLY ASSEMBLED. PICTURES PROVIDED.
