PIPER PA-23-250
DURING THE FLT, HYDRAULIC FAILURE OF THE LANDING SYS OCCURRED & THE AIRCREW WERE UNABLE TO GET THE GEAR LOCKED IN THE DOWN POSITION. AFTER ORBITING FOR OVER AN HOUR, A LANDING WAS MADE. DURING TOUCHDOWN, THE GEAR COLLAPSED. AN EXAM REVEALED THAT AN AILERON BALANCE CABLE HAD CHAFED AGAINST A HYDRAULIC LINE IN THE LANDING GEAR SYS UNTIL A HOLE WAS WORN THRU THE LINE. THIS ALLOWED THE HYDRAULIC FLUID TO LEAK OUT.
