Read the full NTSB narrative

THE RIGHT LANDING GEAR MADE A LOUD NOISE DURING RETRACTION AND THE GEAR 'UNLOCKED' LIGHT REMAINED ON. THE COMMERCIAL PILOT OF THE AIR TAXI CARGO FLIGHT FLEW BY A CONTROL TOWER AT HOLLOMAN AIR FORCE BASE FOR A VISUAL CHECK OF THE LANDING GEAR. TOWER PERSONNEL WERE ABLE TO CONFIRM THE GEAR DID NOT APPEAR TO BE LOCKED DOWN. DURING LANDING ROLL, THE RIGHT MAIN LANDING GEAR FOLDED, THE PLANE SWERVED TO THE RIGHT AND CAME TO REST OFF THE RIGHT SIDE OF THE RUNWAY. A POSTACCIDENT INVESTIGATION REVEALED THAT THE TORQUE TUBE BRACKET ASSEMBLY HAD FAILED AND RESULTED IN THE GEAR DOWN LOCK ASSEMBLY MALFUNCTION.
