Narrative:
While attempting to back-taxi into position for takeoff runway 14R oma, the nose gear departed the runway edge. Aircraft stopped with nose tires sunk into soft sand, approximately 6 ft off hard surface. I set brakes and shut down engines. Passenger were bussed to terminal. Aircraft returned to hard surface by trucks, towed to terminal, no damage noted. Narrow runway coupled with low time in type with no prior back-taxi experience was cause. Additional training conducted which stressed the placement of main and nose gear from cockpit centerline. In addition, proper technique for successful execution of a 180 degree turn on runway was discussed and reviewed. Minimum distance to turn B757 when utilizing proper technique is 120 ft. For B767-200 it is 129 ft and for B767-300 146 ft.

Title: LGT FLC ON BACK-TAXI HAS NOSEWHEEL DEPART THE RWY EDGE AND BECOME STUCK IN THE SAND.
Narrative: WHILE ATTEMPTING TO BACK-TAXI INTO POS FOR TKOF RWY 14R OMA, THE NOSE GEAR DEPARTED THE RWY EDGE. ACFT STOPPED WITH NOSE TIRES SUNK INTO SOFT SAND, APPROX 6 FT OFF HARD SURFACE. I SET BRAKES AND SHUT DOWN ENGS. PAX WERE BUSSED TO TERMINAL. ACFT RETURNED TO HARD SURFACE BY TRUCKS, TOWED TO TERMINAL, NO DAMAGE NOTED. NARROW RWY COUPLED WITH LOW TIME IN TYPE WITH NO PRIOR BACK-TAXI EXPERIENCE WAS CAUSE. ADDITIONAL TRAINING CONDUCTED WHICH STRESSED THE PLACEMENT OF MAIN AND NOSE GEAR FROM COCKPIT CTRLINE. IN ADDITION, PROPER TECHNIQUE FOR SUCCESSFUL EXECUTION OF A 180 DEG TURN ON RWY WAS DISCUSSED AND REVIEWED. MINIMUM DISTANCE TO TURN B757 WHEN UTILIZING PROPER TECHNIQUE IS 120 FT. FOR B767-200 IT IS 129 FT AND FOR B767-300 146 FT.
