In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, approach
  - landing gear,gear locking mechanism - jammed (cause)
  - gear extension - not possible, pilot in command
- In flight collision with terrain/water, landing - flare/touchdown
  - wheels up landing - performed, pilot in command

## Analysis

DURING ARRIVAL AT THE DESTINATION ARPT, THE AIRCREW WAS UNABLE TO EXTEND THE LANDING GEAR BY USING EITHER THE NORMAL OR EMERGENCY SYSTEMS. THEY ELECTED TO RETURN TO ANCHORAGE WHERE EMERGENCY EQUIPMENT WAS AVAILABLE. FUEL WAS REDUCED & SUBSEQUENTLY A WHEELS UP LANDING WAS MADE ON A FOAMED RWY. AN EXAM REVEALED THAT THE RIGHT GIMBAL RING/TRAVEL NUT, P/N A7601A, HAD TRAVELED BEYOND ITS NORMAL DISTANCE & JAMMED AGAINST THE COLLAR ON THE ELECTRIC ACTUATOR.
