## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(.4) WHILE ON APPROACH, THE PILOT PLACED THE LANDING-GEAR HANDLE IN THE DOWN POSITION BUT THE RIGHT MAIN GEAR DID NOT EXTEND. ALL ATTEMPTS TO EXTEND THE RIGHT MAIN GEAR FAILED. THE PILOT LANDED ON THE LEFT MAIN GEAR AND THE NOSE WHEEL. THE RIGHT WING SETTLED TO THE RUNWAY AND THE AIRPLANE VEERED OFF THE RIGHT SIDE OF THE RUNWAY AND COLLIDED WITH A DITCH. A POST-ACCIDENT INSPECTION OF THE LANDING GEAR SYSTEM BY THE FAA REVEALED THAT THE RIGHT MAIN GEAR DRIVE SHAFT HAD BEEN SHEARED, DISABLING THE ACTUATOR. EXAMINATION OF THE ACTUATOR PARTS REVEALED THAT THE RING GEAR WAS MISSING ONE TOOTH AND THE PINION GEAR, WHICH MESHES WITH THE RING GEAR, HAD MISSING AND DAMAGED TEETH. EXAMINATION OF THE UPPER AND LOWER THRUST BEARINGS REVEALED THAT THE LOWER THRUST BEARING HAD BEEN INSTALLED IN REVERSE. THE TYPE OF DAMAGE THE RING AND PINION GEARS EXHIBITED INDICATED THAT THE GEARS WERE NOT MESHING PROPERLY. A THRUST BEARING INSTALLED IN REVERSE COULD CREATE AN INTERFERENCE CONDITION BETWEEN THE GEARS.
