THE PILOT DISCOVERED THAT THE GEAR WOULD NOT EXTEND ELECTRICALLY. MANUAL EXTENSION WAS ATTEMPTED, BUT THE CRANK WOULD NOT TURN IN EITHER DIRECTION. WHILE APPLYING PRESSURE TO THE CRANKS, THE CHAIN DRIVE FAILED. THE PLANE WAS LANDED WITH THE GEAR RETRACTED. DISASSEMBLY OF THE EMERGENCY EXTENSION SYSTEM REVEALED THAT A SHAFT, PN 0843400-50, WAS BENT AND GOUGE MARKS WERE FOUND ON A TOOTH OF A BEVEL GEAR, PN 0843400-49. ALSO, THE MANUAL EXTENSION CHAIN, PN 500000-52, BETWEEN THE HAND CRANK AND BEVEL GEARS, HAD BROKEN. NO OTHER DISCREPANCIES WERE EVIDENT IN THE LANDING GEAR SYSTEM.
