## Discrepancy

AFTER LANDING IT WAS NOTICED THAT THE RIGHT INBOARD LANDING GEAR DOOR SKIN HAD PEELED OFF FROM THE REST OF THE DOOR AT THE LEADING EDGE. UPON FURTHER EXAMINATION THE DOOR SKIN AND SUPPORTING STRUCTURE WHICH ARE BONDED TOGETHER WITH STRUCTURAL ADHESIVE SHOWED CORROSION AT THE BONDING SURFACE ON BOTH THE DOOR SKIN AND THE DOOR STRUCTURE. OPERATORS OF PA42-720 AIRCRAFT MAY WANT TO INSPECT THE LEADING EDGE OF THE INB. LNDG. DOORS FOR CORROSION AND SEPARATION OF THE SKIN.
