HONEYCOMB SIDEPANELS HAVE BECOME DELAMINATED IN NUMEROUS AREAS, EVEN IN THE AREA THAT THE CARRY THROUGH SPAR IS BOLTED TO. THE DELAMINATION OF THE HONEYCOMB PANELS IN THIS AREA REDUCE THE STRUCTURAL INTEGRITY AND MAY ALLOW POSSIBLE SPAR SLIPPAGE AFFECTING THE ANGLE OF INCIDENCE OF THE WINGS WHICH WILL DIRECTLY AFFECT THE FLIGHT CONTROLS BY BINDING THE FLAP AND AILERON TORQUE TUBES. LARGE AMOUNT OF MFG AIRCRAFT WERE BUILT USING A PURPLE GLUE. THIS GLUE WAS WIDELY USED IN THE MID 1970`S AND WAS SUSCEPTIBLE TO BONDED SKIN SECTIONS AND REFERS TO DELAMINATION. (200206996)
