NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE HYDRAULIC POWER PACK RESERVOIR WAS DEPLETED FROM A LEAK IN THE HAND PUMP SUCTION LINE, WHICH HAD BEEN CHAFED THROUGH BY INTERFERENCE WITH THE RIGHT RUDDER CABLE. APPARENTLY, THERE WAS SUFFICIENT BACK PRESSURE REMAINING TO LOWER AND LOCK THE NOSE GEAR, BUT THE MAIN GEAR NEVER EXTENDED BEYOND THE OVER-CENTER LOCKS AND COLLAPSED DURING THE LANDING ROLL. THE LANDING GEAR WARNING HORN WAS IMPROPERLY RIGGED AND NOT FUNCTIONAL. THE PILOT STATED HE OBSERVED A GEAR- DOWN INDICATION (LIGHT). THE INDICATING SYSTEM WAS FOUND TO BE PROPERLY CALIBRATED; HOWEVER, IT COULD NOT HAVE DISPLAYED A GEAR-DOWN LIGHT UNLESS THE MAIN GEAR WERE FULLY EXTENDED. THE PILOT'S STATEMENT IS IN ERROR IN THIS REGARD.
